Android 11.0 接口方式实现 休眠和唤醒

Posted 2022-06-10 王睿丶

△需要权限

• 系统权限：android:sharedUserId="android.uid.system"
• 其他权限：<uses-permission android:name="android.permission.WAKE_LOCK"/>
• 其他权限：<uses-permission android:name="android.permission.DEVICE_POWER"/>

frameworks/base/…/MdmPolicy.java

写好接口供上层调用

    public void sleep()
        SleepAndWakeLockControl.sleep(mContext);
    
    
    public void wake()
        SleepAndWakeLockControl.wake(mContext);
    

frameworks/base/…/SleepAndWakeLockControl.java

具体实现

class SleepAndWakeLockControl 
    public static void sleep(Context context) 
        IPowerManager mPowerManager = IPowerManager.Stub.asInterface(ServiceManager.getService("power"));
        try
            mPowerManager.goToSleep(SystemClock.uptimeMillis()+1,0,0);
        catch (Exception e)
            Log.d("SleepAndWakeLockControl","休眠失败");
        
    

    public static void wake(Context context)
        IPowerManager mPowerManager = IPowerManager.Stub.asInterface(ServiceManager.getService("power"));
        try 
            mPowerManager.wakeUp(SystemClock.uptimeMillis()+1,0,"wakeUp",context.getOpPackageName());
        catch (Exception e)
            Log.d("SleepAndWakeLockControl","唤醒失败");
