copied!<p>Use Alarm Manager. Because your timer can die. But Alarm will wake your app. Try this working code: It wakes CPU every 10 minutes and shows notification.</p> <p>Add to Manifest.xml:</p> <pre><code>... <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> ... <receiver android:process=":remote" android:name="Alarm"></receiver> ... </code></pre> <p>Code:</p> <pre><code>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); } } </code></pre>
