android framework的一些默認配置修改

Reprinted from :

http://blog.csdn.net/tianruxishui/article/details/23277587

在最新代碼中不一定完全一樣修改，但是可以參考思路。

Launcher 總結:

1、launcher的佈局太居中，要想兩邊拉伸

<\packages\apps\Launcher2\res\values\dimens.xml>

apps tab欄的寬度（Launcher2 icon 數目、大小）

\packages\apps\Launcher2\res\layout-sw720dp\workspace.xml>

launcher:cellCountX="10"
launcher:cellCountY="6"

2、或者不想改數目：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizeTabHost.java>

protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {

mTabs.getLayoutParams().width = contentWidth + 108;

3、workspace、AppsCustomize的cell大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

4、裏面icon的大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>

5、workspace沒有拖動，第二頁第一個icon出現在第一頁的最右邊：

加大workspace的寬度，或間距：

workspace的paddingLeft、paddingRight：

<\packages\apps\Launcher2\res\values-sw600dp-land\dimens.xml>

workspace兩屏間距：

修改workspace的字體大小：

如果沒有就添加：

<\packages\apps\Launcher2\res\values-sw480dp\styles.xml>

</style>

6、加wallpaper：

1.<\packages\apps\Launcher2\res\values-sw600dp\wallpapers.xml>

加wallpaper的名字

2.<\packages\apps\Launcher2\res\drawable-nodpi>

加如wallpaper

7、gallery的widget默認添加到workspace上：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

<appwidget
        launcher:packageName="com.android.gallery3d"
        launcher:className="com.android.gallery3d.gadget.PhotoAppWidgetProvider"
        launcher:screen="2"
        launcher:x="1"
        launcher:y="0"
        launcher:spanX="3"
        launcher:spanY="3" />

<\packages\apps\Gallery2\src\com\android\gallery3d\gadget\PhotoAppWidgetProvider.java>

   @Override
   public void onUpdate(Context context,
   for (int id : appWidgetIds) {
                if(id == 2){

                    helper.setWidget(id,WidgetDatabaseHelper.TYPE_SHUFFLE, null);
                }

    }

8、在桌面上添加網頁的快捷方式：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

<shortcut

   launcher:title="@string/application_name"
        launcher:icon="@drawable/ic_no_applications"
        launcher:uri="http://www.aaa.com"
        launcher:screen="0"
        launcher:x="0"
        launcher:y="3" />

9、在桌面上默認放文件夾：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

10、桌面上添加快捷方式，點擊播放視頻：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut launcher:title="@string/application_name"

launcher:icon="@drawable/ic_launcher_application"

launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"

launcher:screen="2"

launcher:x="1"

launcher:y="1" />

11、安裝apk，顯示隱藏的google play：

1.寫google顯示的apk:

GooglePlayShow的activity：

        ComponentName componentname = new ComponentName("com.android.vending", "com.android.vending.AssetBrowserActivity");
        packagemanager.setComponentEnabledSetting(componentname, 1, 1);

        componentname = new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity");
        packagemanager.setComponentEnabledSetting(componentname, 2, 1);

2.<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

   } else if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {
                if (!replacing) {
                         if(packageName.equals("com.example.googleplayshow")){
                              context.startActivity(new Intent().setComponent(new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity")).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));
                         }
                    op = PackageUpdatedTask.OP_ADD;
                } else {
                    op = PackageUpdatedTask.OP_UPDATE;
                }
            }

隱藏google search：

<\packages\apps\Launcher2\src\com\android\launcher2\Launcher.java>

private void setupViews() {

mSearchDropTargetBar = (SearchDropTargetBar) mDragLayer.findViewById(R.id.qsb_bar);
mSearchDropTargetBar.hideSearchBar(false);

void showWorkspace(boolean animated, Runnable onCompleteRunnable) {

//mSearchDropTargetBar.showSearchBar(wasInSpringLoadedMode);

12、widget中隱藏google play：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>

updatePackages裏面添加：

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){

mWidgets.add(widget);

}

13、clock的widget下部分顯示不全，向上調

<\packages\amlogic\Launcher2\res\values\dimens.xml>

修改widget的text的size：

<\packages\amlogic\Launcher2\res\layout\apps_customize_widget.xml>

<TextView xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/widget_name"

android:textSize="20sp" />

14、launcher中隱藏一個app：

需要該app的packageName，例如要隱藏settings：

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

private void loadAllAppsByBatch() {

apps = packageManager.queryIntentActivities(mainIntent, 0);

ResolveInfo removeApp = null;

for(ResolveInfo info:apps){

if(info.activityInfo.packageName.equals("com.android.settings")){

removeApp = info;

}

if(removeApp != null){

apps.remove(removeApp);

}

15、launcher中隱藏多個app：紅色爲改動部分

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>

private void loadAllAppsByBatch() {

final PackageManager packageManager = mContext.getPackageManager();

List<ResolveInfo> apps = new ArrayList<ResolveInfo>();

List<ResolveInfo> allApps = null;

int N = Integer.MAX_VALUE;

int startIndex;

int i=0;

int batchSize = -1;

while (i < N && !mStopped) {

if (i == 0) {

mAllAppsList.clear();

final long qiaTime = DEBUG_LOADERS ? SystemClock.uptimeMillis() : 0;

allApps = packageManager.queryIntentActivities(mainIntent, 0);

for(ResolveInfo info : allApps){

if(info.activityInfo != null

&& !info.activityInfo.packageName.equalsIgnoreCase("com.android.email")

&& !info.activityInfo.packageName.equalsIgnoreCase("com.android.providers.downloads.ui")

&& !info.activityInfo.packageName.equalsIgnoreCase("com.adobe.flashplayer")){

apps.add(info);

}

settings 問題總結:

1.入口，設置分屏顯示

frameworks\base\core\res\res\values\bools.xml 下的 preferences_prefer_dual_pane 爲true.

2.top level headers--這裏可以去掉左邊的headers

<settings.java>

private void updateHeaderList(List<Header> target) {

if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {
target.remove(header);
}

3.默認字體：

public void readFontSizePreference(ListPreference pref) {

ActivityManagerNative.getDefault().getConfiguration()

系統的Configuration是從ActivityManagerService設置的：

<\frameworks\base\services\java\com\android\server\am\ActivityManagerService.java>

mConfiguration.setToDefaults();

fontScale = Float.parseFloat(SystemProperties.get("ro.fontScale","1"));

4.settings的theme:

<\packages\apps\Settings\AndroidManifest.xml>

<\frameworks\base\core\res\res\values\themes.xml>

字體顏色

<item name="textColorPrimary">@android:color/primary_text_holo_dark</item>

加亮框的顏色：

<item name="activatedBackgroundIndicator">@android:drawable/activated_background_holo_dark</item>

觸摸框的顏色：

<item name="listChoiceBackgroundIndicator">@android:drawable/list_selector_holo_dark</item>

左邊背景：

<item name="windowBackground">@android:drawable/screen_background_selector_dark</item>

右邊的背景：

<item name="detailsElementBackground">@android:drawable/panel_bg_holo_dark</item>
title的背景：

<item name="actionBarStyle">@android:style/Widget.Holo.ActionBar</item>

5.設置--》開發者選項--修改後臺進程限制

frameworks/base/services/java/com/android/server$ vi ./am/ActivityManagerService.java

大概839行把int mProcessLimitOverride = -1;改成4(不得超過4個進程)

標準限制對應 -1

不允許後臺進程對應 0

不得超過1個進程對應 1

不得超過2個進程對應 2

不得超過3個進程對應 3

6. 默認不要鎖屏，設置-安全--屏幕鎖定 (無)

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

7. 位置服務--- 默認Google的位置服務爲勾選

overlay/frameworks/base/packages/SettingsProvider/res/values/defaults.xml

改成

<string name="def_location_providers_allowed" translatable="false">gps,network</string>

常用修改
一. 修改默認(Settting.apk 中選項默認值一般存在於 frameworks\base\packages\SettingsProvider\res\values\defaults.xml)
1. 默認勾選未知來源
<bool name="def_install_non_market_apps">false</bool>

2. 默認鈴聲, 通知, 鬧鐘音樂
可以在system.prop 分別配置

ro.config.ringtone=Playa.ogg （默認鈴聲設置，文件在/system/media/audio/ringtones 把喜歡的鈴聲放這裏，比如123.MP3放入ringtones文件夾中，這裏代碼改爲ro.config.ringtone=123.mp3）

ro.config.notification_sound=regulus.ogg （默認提示音，文件在/system/media/audio/notifications 修改方法同上）

ro.config.alarm_alert=Alarm_Beep_03.ogg （默認鬧鈴，文件在/system/media/audio/alarms 修改方法同上）

3. 壁紙不跟隨滑動
packages/apps/Launcher2/./src/com/android/launcher2/Workspace.java 大概 875行
private float wallpaperOffsetForCurrentScroll()
修改 wallpaperOffsetForCurrentScroll 的返回值。改成 return 0.5f;

二.隱藏或刪除某項
1.去掉設置中Wifi選項
device/amlogic/xxxref/xxxref.mk 文件中
# Device specific system feature description
PRODUCT_COPY_FILES += \
$(LOCAL_PATH)/tablet_core_hardware.xml:system/etc/permissions/tablet_core_hardware.xml \
frameworks/native/data/etc/android.hardware.wifi.xml:system/etc/permissions/android.hardware.wifi.xml \ (刪除)

2.去掉設置中藍牙選項
參考 wifi。
在 tablet_core_hardware.xml 刪除 <feature name="android.hardware.bluetooth" /> 這一行

3. HDMI 部分
1）去掉HDMI選項在system.prop中加入 ro.hdmi.autoswitch=false
2）去掉480p 選項在prop中設置 ro.hdmi480p.enable=false

4. 去掉 powerwidget 中某一項
以去掉 gps 爲例

在 packages\apps\Settings\res\layout\widget.xml 下，移除

<ImageView

android:layout_width="1dip"

android:layout_height="match_parent"

android:background="@drawable/appwidget_settings_divider_holo"

android:contentDescription="@null"

<LinearLayout

android:id="@+id/btn_bluetooth"

android:layout_width="0dip"

android:layout_weight="1"

android:layout_height="match_parent"

android:paddingTop="12dp"

android:background="@drawable/appwidget_button_center"

android:clickable="true"

android:focusable="true"

android:orientation="vertical">

<ImageView

android:id="@+id/img_bluetooth"

android:layout_width="match_parent"

android:layout_height="0dip"

android:layout_weight="1"

android:scaleType="center"

android:contentDescription="@null"

<ImageView

android:id="@+id/ind_bluetooth"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:scaleType="fitXY"

android:contentDescription="@null"

</LinearLayout>

然後 com.android.settings.widget.SettingsAppWidgetProvider.java
註釋 views.setOnClickPendingIntent(R.id.btn_gps, getLaunchPendingIntent(context, BUTTON_GPS)); 這一行。

5. 去掉 Setting widget 中某一項
以去掉 "網絡共享與便攜式熱點" 爲例
根據"網絡共享與便攜式熱點" 這個關鍵詞在 values-zh_rCN 中搜索到的 key值，然後在AndroidManifest.xml 搜索這個 key值。找到對於的Activity 配置
移除 <category android:name="com.android.settings.SHORTCUT" /> 這一行。

6. 修改瀏覽器默認瀏覽器模式

packages\apps\Browser\res\xml-sw600dp\advanced_preferences.xml

<ListPreference

android:key="user_agent"

android:title="@string/pref_development_uastring"

android:entries="@array/pref_development_ua_choices"

android:entryValues="@array/pref_development_ua_values"

android:defaultValue="3"/>

修改 android:defaultValue="3" 具體的值參考一下選項

<string-array name="pref_development_ua_choices" translatable="false">

<item>Android</item>

<item>Desktop</item>

<item>iPhone</item>

<item>Froyo-N1</item>

<item>Honeycomb-Xoom</item>

</string-array>

<string-array name="pref_development_ua_values" translatable="false">

7. workspace 預置文件夾

範例

folder 放到最前面。launcher:container 的值是folder的數據庫中的id。一般從1開始。

<folder

launcher:screen="2"

launcher:x="1"

launcher:y="1"

launcher:title ="@string/application_name" >

<favorite

launcher:className="com.android.settings"

launcher:packageName="com.android.settings.Settings"

launcher:container="2"

launcher:x="0"

launcher:y="0" />

<favorite

launcher:className="com.fb.FileBrower"

launcher:packageName="com.fb.FileBrower.FileBrower"

launcher:container="2"

launcher:x="0"

launcher:y="0" />

</folder>

widget 範例

<appwidget

launcher:packageName="com.android.calendar"

launcher:className="com.android.calendar.widget.CalendarAppWidgetProvider"

launcher:screen="1"

launcher:x="0"

launcher:y="0"

launcher:spanX="2"

launcher:spanY="3" />

快捷方式範例

<favorite

launcher:packageName="com.android.settings"

launcher:className="com.android.settings.Settings"

launcher:screen="2"

launcher:x="1"

launcher:y="3" />

網頁快捷方式

<shortcut

launcher:title="@string/custom_google"

launcher:icon="@drawable/favicon_google"

launcher:uri="http://www.google.com/"

launcher:screen="3"

launcher:x="4"

launcher:y="1"/>

8. 系統自帶LatinIME 高級設置--按鍵音量設置修改默認值

java/res/values/keypress-volumes.xml

<string-array name="keypress_volumes" translatable="false">

<item>amlogic,0.3</item> //加入這行。把0.3改成自己的默認值。0.3代表30%

<item>herring,0.5</item>

<item>stingray,0.4</item>

9.lockscreen座標數字時鐘被遮住

請調整紅色的數字：

<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_tab_unlock_land.xml>

<RelativeLayout

android:layout_height="match_parent"

android:layout_weight="0.5"

<RelativeLayout

android:layout_height="match_parent"

android:layout_weight="0.5"

10.在4.1上修改默認字體大小：

比如改成大：

<frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

11.沒有藍牙的平臺，去掉窗口小部件－設置快捷方式－拉到桌面顯示的“藍牙”選項

<\packages\apps\Settings\src\com\android\settings\OutputSettingsBroadcastReceiver.java>

public void onReceive(Context context, Intent intent)

{

// boot completed

if(intent.getAction().equalsIgnoreCase(Intent.ACTION_BOOT_COMPLETED))

{

if(!context.getPackageManager().hasSystemFeature(context.getPackageManager().FEATURE_BLUETOOTH)){

ComponentName componentname = new ComponentName("com.android.settings", "com.android.settings.Settings$BluetoothSettingsActivity");

context.getPackageManager().setComponentEnabledSetting(componentname, 2, 1);

}

11. 修改瀏覽器的默認標籤

分別在一下資源文件中添加自定義的標籤

packages\apps\Browser\res\values\strings.xml

<string-array name="bookmarks" translatable="false">

<item>Google</item>

<item>http://www.google.com/</item>

<item>Picasa</item>

<item>http://picasaweb.google.com/</item>

<item>Yahoo!</item>

<item>http://www.yahoo.com/</item>

<item>Twitter</item>

<item>http://twitter.com/</item>

<item>Facebook</item>

<item>http://www.facebook.com/</item>

<item>Wikipedia</item>

<item>http://www.wikipedia.org/</item>

<item>NY Times</item>

<item>http://www.nytimes.com/</item>

<item>Amazon</item>

<item>http://www.amazon.com/</item>

<item>Weather Channel</item>

<item>http://www.weather.com/</item>

</string-array>

packages\apps\Browser\res\values\bookmarks_icons.xml ，

注意：這裏每個網站對應一個縮略圖和一個favicon

<item>@raw/favicon_google</item>

<item>@raw/thumb_google</item>

<item>@raw/favicon_picasa</item>

<item>@raw/thumb_picasa</item>

<item>@raw/favicon_yahoo</item>

<item>@raw/thumb_yahoo</item>

<item>@raw/favicon_msn</item>

<item>@raw/thumb_msn</item>

<item>@raw/favicon_twitter</item>

<item>@raw/thumb_twitter</item>

<item>@raw/favicon_facebook</item>

<item>@raw/thumb_facebook</item>

<item>@raw/favicon_wikipedia</item>

<item>@raw/thumb_wikipedia</item>

<item>@raw/favicon_ebay</item>

<item>@raw/thumb_ebay</item>

<item>@raw/favicon_cnn</item>

<item>@raw/thumb_cnn</item>

<item>@raw/favicon_nytimes</item>

<item>@raw/thumb_nytimes</item>

<item>@raw/favicon_espn</item>

<item>@raw/thumb_espn</item>

<item>@raw/favicon_amazon</item>

<item>@raw/thumb_amazon</item>

<item>@raw/favicon_weatherchannel</item>

<item>@raw/thumb_weatherchannel</item>

<item>@raw/favicon_bbc</item>

<item>@raw/thumb_bbc</item>

</array>
對應的圖片在 packages\apps\Browser\res\raw

12. 鎖屏界面，解鎖組件增加圖標

已增加 VideoPlayer 爲例，

在frameworks/base/core/res/res/drawable-hdpi 下面

添加一個對應的png圖標

下面紅色爲增加的部分。

frameworks/core/res/res/values-sw600dp-land/arrays.xml

<item>@drawable/ic_lockscreen_unlock</item>

<item>@drawable/ic_action_assist_generic</item>

<item>@drawable/ic_lockscreen_camera</item>

- <item>@null</item>

+ <item>@drawable/ic_lockscreen_videoplayer</item>

</array>

frameworks/base/res/res/values/arrays.xml b/core/res/res/values/arrays.xml

<item>@drawable/ic_lockscreen_unlock</item>

<item>@drawable/ic_action_assist_generic</item>

<item>@drawable/ic_lockscreen_camera</item>

- <item>@null</item>

+ <item>@drawable/ic_lockscreen_videoplayer</item>

</array>

frameworks/base/res/res/values/public.xml b/core/res/res/values/public.xml

index ac0a457..be4257e 100755

--- a/core/res/res/values/public.xml

+++ b/core/res/res/values/public.xml

<java-symbol type="drawable" name="ic_lockscreen_unlock_phantom" />

<java-symbol type="drawable" name="ic_media_route_on_holo_dark" />

<java-symbol type="drawable" name="ic_media_route_disabled_holo_dark" />

<java-symbol type="drawable" name="ic_lockscreen_videoplayer" />

<java-symbol type="layout" name="action_bar_home" />

<java-symbol type="layout" name="action_bar_title_item" />

<java-symbol type="layout" name="action_menu_item_layout" />

frameworks/base/policy/src/com/android/internal/policy/impl/LockScreen.java

case com.android.internal.R.drawable.ic_lockscreen_camera:

launchActivity(new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA));

mCallback.pokeWakelock();

break;

case com.android.internal.R.drawable.ic_lockscreen_videoplayer:

launchActivity(new Intent().setClassName("com.farcore.videoplayer", "com.farcore.videoplayer.FileList"));

mCallback.pokeWakelock();

break;

注意：在 frameworks/base/core/res/ 中執行mm 。然後在frameworks/base/policy 中執行mm。看看能否編譯過。不行的話，在在根目錄下執行make update-api

13. 休眠策略

修改默認的休眠策略，請參考

frameworks\base\packages\SettingsProvider\res\values\defaults.xml

14. Launcher 半透明
4.0， 4.1 下載附件中的patch集合--- translucent.zip
如果是 4.2.2系統，還需修改

Launcher/src/com/android/launcher2/Launcher.java

mLauncherView.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);

mWorkspaceBackgroundDrawable = getResources().getDrawable(R.drawable.workspace_bg);

mBlackBackgroundDrawable = new ColorDrawable(Color.BLACK); // 修改爲 mBlackBackgroundDrawable = new ColorDrawable(0x7f000000);

packages\amlogic\Launcher2\src\com\android\launcher2\Launcher.java

mStateAnimation.addListener(new AnimatorListenerAdapter() {

boolean animationCancelled = false;

@Override

public void onAnimationStart(Animator animation) {

dispatchOnLauncherTransitionEnd(fromView, animated, false); //add

dispatchOnLauncherTransitionEnd(toView, animated, false); //add

updateWallpaperVisibility(false); //true 改成false

// Prepare the position

toView.setTranslationX(0.0f);

toView.setTranslationY(0.0f);

toView.setVisibility(View.VISIBLE);

toView.bringToFront();

}

15. APK 預裝時無法找到lib庫的問題

(1) 如果log報錯是找不到lib庫首先可以修改lib的路徑

jb4.1\frameworks\base\core\java\android\app\NativeActivity.java

public static final String SYSTEM_LIB_PATH = "/system/lib";

if (libraryFile.exists()) {

path = libraryFile.getPath();

}else{

File systemLibraryFile = new File(SYSTEM_LIB_PATH,System.mapLibraryName(libname));

if (systemLibraryFile.exists()) {

path = systemLibraryFile.getPath();

}

}

(2)apk本身會檢測檢測/data/data/lib路徑是否存在資源文件時方法1不適用，用第二種方法：

在項目上的mk文件 /device/amlogic/g18refg/8ref.mk 中,加上 preinstallation

PRODUCT_PACKAGES += \

lights.amlogic \

FileBrowser \

AppInstaller \

VideoPlayer \

HdmiSwitch \

Update \

fw_env \

preinstallation

將網頁底部的附件 Preinstallation.zip拷貝到packages\amlogic下面解壓將需要預裝安裝的apk拷貝到preinstallation目錄下面，編輯裏面的preinstall.sh文件內容如下：

#!/system/xbin/busybox sh

echo "do preinstall applications"

# com.mxtech.videoplayer.ad apk包名

if [ ! -e /data/data/com.mxtech.videoplayer.ad/ ]; then

pm install /system/preinstall/com.mxtech.videoplayer.ad.50.apk

if [ ! -e /data/data/org.xbmc.xbmc/ ]; then

pm install /system/preinstall/xbmc-20130414-e2c3799-Frodo-armeabi-v7a.apk

。。。。。。

然後在device\amlogic\common\init\tablet\init.amlogic.rc 中,啓動預安裝腳本的服務.

MX:

service preinstall /system/bin/preinstall.sh

class main

user root

group root

oneshot

console

disabled

M3:

service preinstall /system/bin/preinstall.sh

user root

group root

disabled

oneshot

在init.amlogic.rc最後一行加上

start preinstall

16. 去掉 hotspot

把紅色的部分刪掉

device\amlogic\gXXXX\overlay\frameworks\base\core\res\res\values\config.xml

<string-array translatable="false" name="config_tether_wifi_regexs">

</string-array>

<integer-array translatable="false" name="config_tether_upstream_types">

</integer-array>

17.桌面上添加快捷方式，點擊播放視頻：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut

launcher:title="@string/application_name"

launcher:icon="@drawable/ic_launcher_application" launcher:uri="file:///mnt/sdcard/external_sdcard/1...playermenu;end"

launcher:screen="2" launcher:x="1" launcher:y="1" />

添加網頁的快捷方式：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

<shortcut

18.去掉camera的全景icon：

4.1：

<\packages\apps\Camera\res\layout-sw600dp-land\mode_picker.xml>

<com.android.camera.ui.RotateImageView android:id="@+id/mode_panorama"

android:contentDescription="@string/accessibility_switch_to_panorama"

android:layout_width="match_parent"

android:layout_height="wrap_content"

android:layout_weight="1"

android:visibility="gone"

android:scaleType="center"

android:background="@drawable/bg_pressed"

android:src="@drawable/ic_switch_pan_holo_light" />

4.2：

<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>

加上紅色加亮的地方：

public void init() {

for (int i = 0; i < mDrawables.length; i++) {

if ((i == LIGHTCYCLE_MODULE_INDEX && !LightCycleHelper.hasLightCycleCapture(this))||i == PANORAMA_MODULE_INDEX) {

continue; // not enabled, so don't add to UI

}

drawids[ix++] = DRAW_IDS[i];

}

<\packages\apps\Camera\src\com\android\camera\CameraActivity.java>

public void init() {

int[] drawids = new int[LightCycleHelper.hasLightCycleCapture(this)

? DRAW_IDS.length -1 : DRAW_IDS.length - 2];

19.鎖屏左邊clock太大顯示不全：

<\frameworks\base\core\res\res\layout-sw600dp\keyguard_screen_status_land.xml>

<TextView android:id="@+id/timeDisplayBackground"

android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"

<TextView android:id="@+id/timeDisplayForeground"

android:textSize="@dimen/keyguard_pattern_unlock_clock_font_size"

//dimens.xml裏的keyguard_pattern_unlock_clock_font_size調小

可以把clock調成居中顯示，不要靠右，造成右邊顯示不全

<LinearLayout

xmlns:android="http://schemas.android.com/apk/res/android"

android:orientation="vertical"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:gravity="right">

//改成center

20. 去掉settings的battery裏面的mobile network signal顯示

加上紅色語句：

<\packages\apps\Settings\src\com\android\settings\fuelgauge\BatteryHistoryChart.java>

if (!com.android.settings.Utils.isWifiOnly(getContext())) {

mHavePhoneSignal = true;

}

mHavePhoneSignal = false;

21. 去掉待機的CRT動畫

把自己項目overlay中的

frameworks/base/core/res/res/values/config.xml

<bool name="config_animateScreenLights">false</bool> 刪掉就可以了

22. 添加格式化內部sdcard

jb4.1\packages\amlogic\Settings\src\com\android\settings\deviceinfo\StorageVolumePreferenceCategory.java

public StorageVolumePreferenceCategory(Context context, Resources resources, StorageVolume storageVolume, StorageManager storageManager, boolean isPrimary) {

// Cannot format emulated storage

mAllowFormat = mStorageVolume != null && !mStorageVolume.isEmulated()&&mStorageVolume.isRemovable();

// For now we are disabling reformatting secondary external storage

// until some interoperability problems with MTP are fixed

//if (!isPrimary) mAllowFormat = false;

+ if(mStorageVolume != null && mStorageVolume.getPath().equals("/storage/sdcard0")){

+ mAllowFormat = true;

+ }

23. 4.2 LockScreen 任何方向都可以解鎖，修改成只有向右才能解鎖

4.2 Lockscreen 對應的java 文件不再是 Lockscreen, 而是KeyguardSelectorView.java

frameworks/base/core/res/res/values/arrays.xml b/core/res/res/values/arrays.xml

<item>@*android:drawable/ic_lockscreen_unlock</item>

+ <item>@null</item>

</array>

<item>@*android:string/description_target_unlock</item>

+ <item>@null</item>

</array>

24.android 4.2改launcher裏面的icon橫排的數目：

<\packages\apps\Launcher2\res\values-sw720dp\config.xml>

如果改成7，hotseat裏面第8個icon不見了，可以往第8個槽裏面放進去，但是重啓後，icon又不見了，可以這樣修改：

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>
final ItemInfo occupied[][][] =
new ItemInfo[Launcher.SCREEN_COUNT + 1][mCellCountX + 2][mCellCountY + 1]; //原來這裏是+1

25. 4.2 LockScreen 解鎖界面四個方向添加一個setting入口

frameworks\base\core\res\res\values/arrays.xml

<item>@drawable/ic_lockscreen_unlock</item>

<item>@drawable/ic_action_assist_generic</item>

<item>@drawable/ic_lockscreen_camera</item>

<item>@drawable/ic_lockscreen_settings</item>

</array>

在 frameworks\base\core\res\res\drawable 增加 ic_lockscreen_settings.xml 文件並添加 ic_lockscreen_settings_normal.phg ic_lockscreen_settings_activated.png 資源文件

<item

android:state_enabled="true"

android:state_active="false"

android:state_focused="false"

android:drawable="@drawable/ic_lockscreen_settings_normal" />

<item

android:state_enabled="true"

android:state_active="true"

android:state_focused="false"

android:drawable="@drawable/ic_lockscreen_settings_activated" />

<item

android:state_enabled="true"

android:state_active="false"

android:state_focused="true"

android:drawable="@drawable/ic_lockscreen_settings_activated" />

</selector>

frameworks\base\policy\src\com\android\internal\policy\impl\LockScreen.java

public void onTrigger(View v, int target) {

final int resId = mGlowPadView.getResourceIdForTarget(target);

switch (resId) {

case com.android.internal.R.drawable.ic_lockscreen_settings: //啓動setting 應用

launchActivity(new Intent().setComponent(new ComponentName("com.android.settings","com.android.settings.Settings")));

mCallback.pokeWakelock();

break;

26. 4.2 上隱藏 Wifi Display

去掉項目overlay/frameworks/base/core/res/res/config.xml 中的config_enableWifiDisplay

27. 默認音量修改

frameworks/base/media/java/android/media/AudioService.java

private final int[] MAX_STREAM_VOLUME = new int[] {

5, // STREAM_VOICE_CALL

7, // STREAM_SYSTEM

7, // STREAM_RING

15, // STREAM_MUSIC

7, // STREAM_ALARM

7, // STREAM_NOTIFICATION

15, // STREAM_BLUETOOTH_SCO

7, // STREAM_SYSTEM_ENFORCED

15, // STREAM_DTMF

15 // STREAM_TTS

};

frameworks/base/media/java/android/media/AudioManager.java

/** @hide Default volume index values for audio streams */

public static final int[] DEFAULT_STREAM_VOLUME = new int[] {

4, // STREAM_VOICE_CALL

7, // STREAM_SYSTEM

5, // STREAM_RING

11, // STREAM_MUSIC

6, // STREAM_ALARM

5, // STREAM_NOTIFICATION

7, // STREAM_BLUETOOTH_SCO

7, // STREAM_SYSTEM_ENFORCED

11, // STREAM_DTMF

11 // STREAM_TTS

};

28.widget中隱藏google play：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>

updatePackages裏面添加：

if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){

mWidgets.add(widget);

}

29.去掉設置-->顯示-->亮度裏的“自動調整亮度”選項

<\packages\apps\Settings\res\layout\preference_dialog_brightness.xml>

<CheckBox android:id="@+id/automatic_mode"

加上

android:visibility="invisible"

30.設置-位置信息訪問權限默認關閉

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

這裏不要填寫gps或者network，清空

<bool name="def_package_verifier_enable">false</bool>

32.設置-聲音-觸摸提示音與鎖屏提示音默認不勾允狀態

<\frameworks\base\packages\SettingsProvider\res\values\defaults.xml>

<bool name="def_sound_effects_enabled">false</bool>

33.設置-以太網菜單請移動“更多”菜單下

請用附件ethernet.patch，開關是ro.ethernet.more，設置爲true，ethernet移到more裏面

在settings的git下打這個patch

34.窗口小部件“指針時鐘”顯示不全

把clock的widget向上調，下面的值改小：

<\packages\amlogic\Launcher2\res\values\dimens.xml>

35.去掉settings的more裏面的網絡共享與便攜式熱點

ro.tether.denied=true

36.平臺主界面底部工具欄上的圖標全部居中顯示，從左至右的圖標依次爲：vol-、back、home、窗口切換、vol+

1.在prop裏面將ro.statusbar.volume設置爲true

2.<\frameworks\base\packages\SystemUI\res\layout-sw600dp\navigation_bar.xml>

將

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/sub"

……

這段放到

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/back"

……

這段之前

<com.android.systemui.statusbar.policy.KeyButtonView android:id="@+id/add"

……

這段放到

<com.android.systemui.statusbar.policy.KeyButtonView

android:id="@+id/recent_apps"

……

這段之後

注意這個文件有兩處需要調換上面的

37.主界面模擬時鐘改成數字時鐘

default_workspace.xml裏面加上：

<appwidget

launcher:packageName="com.android.deskclock"

launcher:className="com.android.alarmclock.DigitalAppWidgetProvider"

38、settings中的developer options的開關打開，debug關掉：

<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

private void loadSecureSettings(SQLiteDatabase db) {

loadSetting(stmt, Settings.Secure.ADB_ENABLED, 0);
loadSetting(stmt, Settings.Secure.DEVELOPMENT_SETTINGS_ENABLED, 1);

39、改桌面icon行、列數：

<\packages\apps\Launcher2\res\layout-sw***dp\workspace.xml>

launcher:cellCountX="10"

launcher:cellCountY="6"

40、more裏面morebile data項默認不選：

1.<\frameworks\base\packages\SettingsProvider\src\com\android\providers\settings\DatabaseHelper.java>

private void loadSecureSettings(SQLiteDatabase db) {

SQLiteStatement stmt = null;

try {

stmt = db.compileStatement("INSERT OR IGNORE INTO secure(name,value)"

+ " VALUES(?,?);");

添加：

loadIntegerSetting(stmt, Settings.Secure.MOBILE_DATA,

R.integer.def_mobile_data);

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:launcher="http://schemas.android.com/apk/res/c...droid.launcher"

android:background="@drawable/wallpaper_03">

43、bluetooth tethering的checkbox去掉：

overlay裏面的

<\frameworks\base\core\res\res\values\config.xml>

<string-array translatable="false" name="config_tether_bluetooth_regexs">
<item>"bt-pan"</item>
</string-array>

去掉<item>"bt-pan"</item>

44. Google play 不是內置，而是安裝，導致出問題的解決辦法

frameworks/baseservices/java/com/android/server/pm/PackageManagerService.java

@@ -4594,6 +4594,9 @@ public class PackageManagerService extends IPackageManager.Stub {

}

+ if (pkg.packageName.equals("com.android.vending")){

+ allowed = true;

+ }

if (!allowed && (bp.protectionLevel

& PermissionInfo.PROTECTION_FLAG_DEVELOPMENT) != 0) {

// For development permissions, a development permission

45.以太網設置問題

以太網在settings.db中的條目是"eth_on", 默認值由系統屬性 ro.ethernet.default_on 決定，

ro.ethernet.default_on=false 默認關閉

ro.ethernet.default_on=true默認打開

不定義該屬性默認關閉
