Android系統之路(初識MTK) ------ 內置三方apk到Rom可移動/可卸載

客戶給了一個內置他們自己apk的需求，定製到Rom裏，我們需要在編譯系統源碼的時候配置好相關的文件即可將apk一起打包到ROM裏面，下面我們就來一起打包apk到系統

首先需要在 device/mediatek/common/device.mk 配置如下語句

$(call inherit-product-if-exists, vendor/公司名/product/您的命名.mk)

在mk文件裏面配置需要內置的apk label

eg:

#apps
PRODUCT_PACKAGES += \
			BDDataPlan\
			Facebook\
			MultiLingBengaliPlugin\
			Multilingkeyboard\
			SHAREit\
			Skype\
			Viber\
			WPSOffice\
			WST_WAL_C

配置好之後還需要導入 apk文件並且配置宏，就寫一個例子吧，也在這個文件夾下寫

路徑：vendor\公司名\ThirdpartyApps\

配置如下mk文件，沒有的自己創建

LOCAL_PATH := $(call my-dir)
#
include $(CLEAR_VARS)
LOCAL_MODULE := BDDataPlan
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Facebook
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := MultiLingBengaliPlugin
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Multilingkeyboard
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := SHAREit
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Skype
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := Viber
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := WPSOffice
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

#
include $(CLEAR_VARS)
LOCAL_MODULE := WST_WAL_C
LOCAL_MODULE_TAGS := optional
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/operator/app
#LOCAL_MODULE_PATH := $(TARGET_OUT)/vendor/thirdparty_apps
LOCAL_SRC_FILES := $(LOCAL_MODULE).apk
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_CERTIFICATE := PRESIGNED
include $(BUILD_PREBUILT)

工作算是完成了一半，接下來還需要修改frameworks下的java文件，讓內置的三分apk可卸載等操作

/frameworks/base/services/core/java/com/android/server/pm/PackageManagerService.java

添加：

+            final File thirdpartyAppDir = new File(Environment.getRootDirectory(), "/vendor/thirdparty_apps");

+            scanDirLI(thirdpartyAppDir, PackageParser.PARSE_IS_SYSTEM

+                    | PackageParser.PARSE_IS_SYSTEM_DIR, scanFlags, 0);

添加：

+    private static boolean isThirdpartyApp(int parseFlags) {

+               return (parseFlags & PackageParser.PARSE_IS_THIRDPARTY_APP) != 0;

+       }

public static int PackageParser.PARSE_IS_THIRDPARTY_APP = 1<<11;

修改：

+        if (isSystemApp(pkg) && !isUpdatedSystemApp(pkg) && !isThirdpartyApp(parseFlags)) {

不知道在那行的，可以搜索關鍵字，ctrl+L 索引行

修改完之後編譯工程，發現以下異常：

 No rule to make target `vendor/rmt/ThirdpartyApps/WST_WAL_C.apk', needed by `out/target/product/rmt8382_tb_l/obj/APPS/WST_WAL_C_intermediates/package.apk'.  Stop

檢查了下配置文件，發現客戶提供的apk文件跟我們的mk衝突了，於是修改

WST_WAL_C.APK 爲 WST_WAL_C.apk

重新編譯工程，完美運行

最終效果，內置9個apk，7個可見，2個後臺
