I want to make my alarmmanager to rings although after my application closed.

But now my code don`t call broadcastreceiver after my application closed.

I reg my broadcastreceiver in my manifest.

This is code that setting alarmmanager

final AlarmManager alarmManager=(AlarmManager) getSystemService(ALARM_SERVICE);
Intent intent=new Intent(setTimeActivity.this,autoCheckReceiver.class);
intent.setAction("com.dayo.selfcheck.autoCheckReceiver");
final PendingIntent pendingIntent=PendingIntent.getBroadcast(setTimeActivity.this,0,intent,PendingIntent.FLAG_UPDATE_CURRENT);

alarmManager.cancel(pendingIntent);
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, timePicker.getHour());
calendar.set(Calendar.MINUTE, timePicker.getMinute());
calendar.set(Calendar.SECOND, 0);
calendar.set(Calendar.MILLISECOND, 0);
alarmManager.setInexactRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), AlarmManager.INTERVAL_DAY, pendingIntent);

And this code is my broadcastreceiver.

public class autoCheckReceiver extends BroadcastReceiver {

    private String TAG="autoCR";
    @Override
    public void onReceive(Context context, Intent it) {
        Log.d(TAG,"asdf");
        Intent i = new Intent();
        i.setClassName("com.dayo.selfcheck", "com.dayo.selfcheck.MainActivity");
        i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(i);
    }
}

this is my manifest file.

<receiver
            android:name=".autoCheckReceiver"
            android:exported="false">
            <intent-filter>
                <action android:name="com.dayo.selfcheck.autoCheckReceiver"></action>
            </intent-filter>
</receiver>

thanks!

You MUST specify android:exported="true" on your <receiver> declaration in order for AlarmManager to launch your BroadcastReceiver.

You don't need to call cancel() on the AlarmManager to cancel the Intent before you schedule it, as AlarmManager automatically does this.

You do not need to set the ACTION in the Intent for the broadcast, since you are using an explicit Intent (you have specified the exact component to be used).

You also do not need to provide the <intent-filter> in your <receiver> declaration because you are using an explicit broadcast.
