这是我的代码.它工作正常，但一段时间后(大约 1 小时)它不起作用.怎么了?提前致谢.

This is my code. It works correctly, but after some time (about 1 hour) it doesn't work. Whats wrong? Thanks in advance.

<uses-permission android:name="android.permission.READ_PHONE_STATE"></uses-permission> public class Alarm extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { Toast.makeText(context, "Alarm !!!!!!!!!!!!!", Toast.LENGTH_LONG).show(); } public void SetAlarm(Context context) { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, Alarm.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); am.setRepeating(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime(), 1000 * 60 * 10, pi); } public void StopAlarm(Context context) { Intent intent = new Intent(context, Alarm.class); PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarmManager.cancel(sender); } }

推荐答案

这是工作代码.它每 10 分钟唤醒一次 CPU 并显示通知.

This is working code. It wakes CPU every 10 minutes and shows notification.

添加到 Manifest.xml:

Add to Manifest.xml:

... <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> ... <receiver android:process=":remote" android:name="Alarm"></receiver> ...

代码:

public class Alarm extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) { PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "YOUR TAG"); wl.acquire(); // Put here YOUR code. Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); // For example wl.release(); } public void SetAlarm(Context context) { AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); Intent i = new Intent(context, Alarm.class); PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 10, pi); // Millisec * Second * Minute } public void CancelAlarm(Context context) { Intent intent = new Intent(context, Alarm.class); PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); alarmManager.cancel(sender); } }
