Question

我想要在启动或启动android mobile时显示消息或通知。通知显示，但是当我销毁应用程序时，它不显示消息或通知。所以请任何人帮助我。

public class BeaconService extends Service { 
    Handler mHandler = new Handler(); 
    @Override 
    public IBinder onBind(Intent arg0) { 
     return null; 
    } 

    @Override 
    public int onStartCommand(Intent intent, int flags, int startId) { 
     new Thread(new Runnable() { 
      @Override 
      public void run() { 
       while (true) { 
        try { 
         Thread.sleep(10000); 
         mHandler.post(new Runnable() { 
          @Override 
          public void run() { 
           showNotification(); 
          } 
         }); 
        }catch (Exception e){ 

        } 
       } 
      } 
     }).start(); 
     return START_STICKY; 
    } 

    private void showNotification() { 
     NotificationCompat.Builder mBuilder = 
       (NotificationCompat.Builder) new NotificationCompat.Builder(this) 
         .setSmallIcon(R.drawable.ic_loc) 
         .setContentTitle("Welcome to Ford Show Room") 
         .setContentText("Hello Puneet, Welcome to Ford! You'll be shortly attended by Karthik! ") 
         .setPriority(2) 
         .setOnlyAlertOnce(true); 
     Intent resultIntent = new Intent(this, SlideMenuActivity.class); 
     TaskStackBuilder stackBuilder = TaskStackBuilder.create(this); 
     stackBuilder.addParentStack(SlideMenuActivity.class); 
     stackBuilder.addNextIntent(resultIntent); 
     NotificationManager mNotificationManager = 
       (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
     mNotificationManager.notify(2001, mBuilder.build()); 
    } 
} 

BeaconReceiverService.java

public class BeaconReceiverService extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     Log.d("DEBUG", "Creating the intent"); 
     Intent service = new Intent(context, BeaconService.class); 
     context.startService(service); 
    } 
} 

服务在menifest.xml

<service 
      android:name=".BeaconService" 
      android:enabled="true" 
      android:exported="true"> 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      </intent-filter> 
     </service> 

     <receiver android:name=".BeaconReceiverService"> 
      <intent-filter> 
       <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      </intent-filter> 
     </receiver> 

Answer 1

这下面的事情肯定行之有效

AndroidManifest.xml中

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" /> 

<application 
    >  

    <receiver android:name=".BootCompletedReceiver" > 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
      <action android:name="android.intent.action.QUICKBOOT_POWERON" /> 
     </intent-filter> 
    </receiver> 

    <service android:name="NotifyingDailyService" > 
    </service> 

BootCompletedReceiver类

public class BootCompletedReceiver extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent arg1) { 
    // TODO Auto-generated method stub 
    context.startService(new Intent(context, NotifyingDailyService.class)); 
} 

} 

服务类

public class NotifyingDailyService extends Service { 

@Override 
public IBinder onBind(Intent arg0) { 
    // TODO Auto-generated method stub 
    return null; 
} 

    @Override 
    public int onStartCommand(Intent pIntent, int flags, int startId) { 
     // TODO Auto-generated method stub 
     Toast.makeText(this, "Notification", Toast.LENGTH_LONG).show(); 

     return super.onStartCommand(pIntent, flags, startId); 
    } 
    }
