من يك فايل جاوا بنام MyNotification ساختم و اين كدها را داخلش گذشتم
public class MyNotification extends BroadcastReceiver {
PendingIntent pi;
Intent intent;
NotificationManager notificationManager;
Notification notification;
@Override
public void onReceive(Context context, Intent intent) {
context.startService(new Intent(context, MyService.class));
Log.d("AlarmController", "StartAlarm");
}
public class MyService extends Service {
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.d("AlarmController", "StartAlarm");
notificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
intent = new Intent(this,MyNotification.class);
pi = PendingIntent.getActivity(this, (int) System.currentTimeMillis(), intent, 0);
notification = new Notification.Builder(this)
.setContentTitle("عنوان")
.setContentText("متن اعلان")
.setSmallIcon(R.drawable.icon)
.setContentIntent(pi)
.setOngoing(true)
.build();
notificationManager.notify(0,notification);
return Service.START_FLAG_REDELIVERY;
//return START_STICKY;
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
public class AlarmController {
private Context m_Context;
private AlarmManager mgr;
private static final long PERIOD = 6000*60 ;
public AlarmController(Context context){
m_Context = context;
mgr = (AlarmManager)m_Context.getSystemService(Context.A LARM_SERVICE);
Log.d("AlarmController", "StartAlarm");
}
public void StartAlarm(){
StopAlarm();
Intent i = new Intent(m_Context, MyNotification.class);
PendingIntent pi=PendingIntent.getBroadcast(m_Context, 0,i, PendingIntent.FLAG_UPDATE_CURRENT);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAK EUP, SystemClock.elapsedRealtime(),PERIOD,pi);
Log.d("AlarmController", "StartAlarm");
}
public void StopAlarm(){
Intent i = new Intent(m_Context, MyNotification.class);
PendingIntent pi=PendingIntent.getBroadcast(m_Context, 0,i, PendingIntent.FLAG_UPDATE_CURRENT);
mgr.cancel(pi);
Log.d("AlarmController", "StopAlarm");
}
}
public class OnBootReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
AlarmController alarm = new AlarmController(context);
alarm.StartAlarm();
}
}
}
در مانيفست برنامه هم اينها را نوشتم
<receiver android:name=".MyNotification" ></receiver>
<receiver
android:name=".MyNotification$OnBootReceiver"
android:enabled="true" >
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service android:name=".MyNotification$MyService" >
</service>
اما وقتي موقع اجراي آلارم ميشه اين خطا را ميدهد:
MyNotification$MyService has no zero argument constructor
خيلي هم گشتم ولي چيزي پيدا نكردم
