장치를 깨우지 않는 알람

Question

Athan Time에서 알람을 포함하는 Android 용기도 시간 앱을 만들었지 만 적시에 장치를 깨우지 않는 시간은 늦게

늦을 것입니다.

이것은 내 알람 의도

public class AlarmScreenActivity extends Activity {

public final String TAG = this.getClass().getSimpleName();

private WakeLock mWakeLock;
private MediaPlayer mPlayer;
private static final int WAKELOCK_TIMEOUT = 60 * 4000;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    //Setup layout
    this.setContentView(R.layout.activity_alarm_screen);

    // Set the window to keep screen on
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

    // Acquire wakelock
    PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
    if (mWakeLock == null) {
        mWakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK , TAG);
    }

    if (!mWakeLock.isHeld()) {
        mWakeLock.acquire();
        Log.i(TAG, "Wakelock aquired!!");
    }


    Button dismissButton = (Button) findViewById(R.id.alarm_screen_button);
    dismissButton.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View view) {
            mPlayer.stop();
            finish();
        }
    });
    dismissButton.setTypeface(face);
    dismissButton.setText(res.getString(R.string.rd_ok));
    //Play alarm tone
    mPlayer = new MediaPlayer();
    try {
        Uri toneUri = Uri.parse(tone);
        mPlayer.setDataSource(this, toneUri);
        mPlayer.setAudioStreamType(AudioManager.STREAM_ALARM);
        mPlayer.prepare();
        mPlayer.start();


    } catch (Exception e) {
        e.printStackTrace();
    }

    //Ensure wakelock release
    Runnable releaseWakelock = new Runnable() {

        @Override
        public void run() {
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
            getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);

            if (mWakeLock != null && mWakeLock.isHeld()) {
                mWakeLock.release();
            }
        }
    };

    new Handler().postDelayed(releaseWakelock, WAKELOCK_TIMEOUT);
}

@Override
protected void onPause() {
    super.onPause();

    if (mWakeLock != null && mWakeLock.isHeld()) {
        mWakeLock.release();
    }

}

@Override
protected void onDestroy() {
    super.onDestroy();

    if (mPlayer.isPlaying()) {
        mPlayer.stop();
    }
}

.

}

및 AndroidManifest 파일의 허가를 추가했습니다

<uses-permission android:name="android.permission.WAKE_LOCK" />

.

그것을 정정하도록 도와주세요

Answer 1

왜

로 시도하지 않습니까?

getWindow (). addFlags (windowmanager.layoutparams.flag_keep_screen_on);

이 스레드에서 권장하는대로

Wakelock과 Flag_keep_screen_on의 차이점?

알람을위한 것이면 더 의미가 있습니다.
