Android P中设置电池中省电模式默认开启

Android P中设置电池中省电模式默认开启

如图：

修改如下：

vendor/mediatek/proprietary/packages/apps/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java中t添加值：

 private void loadGlobalSettings(SQLiteDatabase db) {SQLiteStatement stmt = null;try {stmt = dbpileStatement("INSERT OR IGNORE INTO global(name,value)"+ " VALUES(?,?);");//add beginloadSetting(stmt, Settings.Global.LOW_POWER_MODE,1);loadSetting(stmt, Settings.Global.LOW_POWER_MODE_STICKY,1);//loadSetting(stmt, Settings.Global.LOW_POWER_MODE_TRIGGER_LEVEL,15);//end			// --- Previously in 'system'loadBooleanSetting(stmt, Settings.Global.AIRPLANE_MODE_ON,R.bool.def_airplane_mode_on);......................
}

或者修改如下类：

frameworks/base/services/core/java/com/android/server/power/batterysaver/BatterySaverStateMachine.java

 /*** {@link com.android.server.power.PowerManagerService} calls it when the system is booted.*/public void onBootCompleted() {if (DEBUG) {Slog.d(TAG, "onBootCompleted");}// Just booted. We don't want LOW_POWER_MODE to be persisted, so just always clear it.putGlobalSetting(Global.LOW_POWER_MODE, 1);//直接置为1
.....
.....
}
