我在 Android 上的闹钟程序不适用于许多三星和 HTC 设备；在手动打开屏幕之前，它不会打开屏幕并且不会播放警报。这个问题出现在 Sony Xperia P 和 Huawei Honor 手机中......我使用任何我认为可以在我的代码中解决我的问题的东西，但它没有解决！:(
这是我的代码：
try {
// baraye roshan kardane safe va roshan negah dashtane oon dar Huawei honor
PowerManager mPowerManager = (PowerManager) PlayAlarmActivity.this.getSystemService(Context.POWER_SERVICE);
mWakeLock = mPowerManager.newWakeLock((PowerManager.FULL_WAKE_LOCK
| PowerManager.ACQUIRE_CAUSES_WAKEUP), "Power Manager");
mWakeLock.acquire();
Log.i("Unlock Screen", "1");
} catch (Exception e) {
Log.e("Error in playalarmactivity for unlock screen 1 ...", e.toString());
}
try {
// 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);
Log.i("Unlock Screen", "2");
} catch (Exception e) {
Log.e("Error in playalarmactivity for unlock screen 2 ...", e.toString());
}
try {
// baraye baz kardane lock dar gooshihayi mesle sonye Masoud!!! :D
km = (KeyguardManager) PlayAlarmActivity.this.getSystemService(Context.KEYGUARD_SERVICE);
kl = km.newKeyguardLock("MyKeyguardLock");
kl.disableKeyguard();
Log.i("Unlock Screen", "3");
} catch (Exception e) {
Log.e("Error in playalarmactivity for unlock screen 3 ...", e.toString());
}
