Android framework累积

提高APK的进程级别：

....\frameworks\base\services\core\java\com\android\server\am\ActivityManagerSerice.java

 

ActivityManagerSerice类里 systemReady()  方法添加如下代码：

synchronized(this) {
            if (mSystemReady) {
                // If we're done calling all the receivers, run the next "boot phase" passed in by the SystemServer
                if (goingCallback != null) {
                    goingCallback.run();
                }
                return;
            }
			
			// add start
            starthService();
			
			Settings.Global.putInt(mContext.getContentResolver(), Settings.Global.AUTO_TIME, 1);
            Settings.Global.putInt(mContext.getContentResolver(), Settings.Global.AUTO_TIME_GPS, 1);
            Settings.System.putInt(mContext.getContentResolver(), Settings.System.AUTO_TIME_GPS, 1);
			
			String oper = SystemProperties.get("ro.operator.oper");
			if (oper != null) {
				if (oper.startsWith("xxxx")) {
				     // dosomething
				}
			}
			
			String model = Build.MODEL;
			if (model != null) {
				if (model.equals("CarL")) {
					Settings.System.putInt(mContext.getContentResolver(), "xxxxxxx", 0);
					
					int tasWallpaperIndex = SystemProperties.getInt("ro.tas.wallpaper", 0);
					Settings.System.putInt(mContext.getContentResolver(), "xxxxxxxx", tasWallpaperIndex);
				}
			}

 

 

只能安装指定的APK

。。。。。。。。\frameworks\base\services\core\java\com\android\server\pm\PackageManagerServicejava
