最近到4412最基本的都調了 然後覺得沒事做了 所以增加一個HDMI的設置 不能閒着
以下使用的是廣州斯道的icool210開發板 源碼修改如下
最開始我是先在設置里加上這些設置然後在去實現功能 這裏就一起說了 之前android2.3裏有HDMI設置所以這裏就參照那個增加 首先修改Setting
查看libhdmi庫首先查看下hdmi能設置的格式 源碼路徑
device/samsung/common/s5p/libhdmi/SecHdmi.cpp
你會發現有如下代碼
mHdmiResolutionValueList[0] = 1080960;
mHdmiResolutionValueList[1] = 1080950;
mHdmiResolutionValueList[2] = 1080930;
mHdmiResolutionValueList[3] = 1080160;
mHdmiResolutionValueList[4] = 1080150;
mHdmiResolutionValueList[5] = 720960;
mHdmiResolutionValueList[6] = 720950;
mHdmiResolutionValueList[7] = 5769501;
mHdmiResolutionValueList[8] = 5769502;
mHdmiResolutionValueList[9] = 4809601;
mHdmiResolutionValueList[10] = 4809602;源碼路徑 packages/apps/Settings/res/values/arrays.xml
增加如下代碼
<!-- TV Out settings. -->

增加如下內容:
/**

*/
public static final String TV_MODE = "tv_mode";
/**
* The tv out resolution.
*/
public static final String TV_RESOLUTION = "tv_resolution";
/**
* The tv out mode.
*/
public static final String TV_HDCP = "tv_hdcp";會在public static final String[] SETTINGS_TO_BACKUP這個數組裏找到一個 然後在它下面增加如下
TV_MODE,
TV_RESOLUTION,
TV_HDCP,接着增加調用hdmi相關函數的接口 這裏我是直接把2.3的拷過來然後進行的修改
創建相應目錄增加以下文件frameworks/base/slsi/java/com/slsi/sec/android/HdmiService.java

}在FRAMEWORKS_BASE_SUBDIRS裏增加slsi \
我們要讓他啓動的時候能能自動設置成設置的參數所以
接着修改frameworks/base/services/java/com/android/server/SystemServer.java
