Broadcast Empfänger weiter nach der Anwendung verlassen

Question

Ich habe ein Problem, das ich nicht lösen kann, der Broadcast-Empfänger meiner Anwendung läuft weiter, wenn ich meine Anwendung verlassen. Ich muss die Anwendung zwangsweise manuell stoppen, während ich geschlossen bin. Vielen Dank für Ihre Hilfe. Hier ist mein Manifest, und mein Empfänger:

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.locateit.antholife.locateit">

    <activity android:name=".Smsconnection"

und myreceiver:

public class MyReceiver extends BroadcastReceiver { 
public MyReceiver() {

public int lock = 0; 

@Override 
public void onReceive(Context context, Intent intent) { 


    Bundle extra = intent.getExtras(); 
    if (extra != null) { 
     Object[] pdus = (Object[]) extra.get("pdus"); 
     final SmsMessage[] messages = new SmsMessage[pdus.length]; 
     for (int i = 0; i < pdus.length; i++) { 
      messages[i] = SmsMessage.createFromPdu((byte[]) pdus[i]); 
     } 
     if (messages.length > -1) { 
      for (int i = 0; i < messages.length; i++) { 
       String messageBody = messages[i].getMessageBody(); 
       String phoneNumber = messages[i].getDisplayOriginatingAddress(); 
       Toast.makeText(context, "Expéditeur:" + "\n" + phoneNumber, Toast.LENGTH_LONG).show(); 
       Toast.makeText(context, "Message : " + "\n" + messageBody, Toast.LENGTH_LONG).show();

        Toast.makeText(context, "Merci de renseigner un numéro correct", Toast.LENGTH_LONG).show(); 

       } **/ 
      } 
     } 
    } 
    }

Answer 1

Sie haben MyReceiver im Manifest registriert. Daher ist es so eingerichtet, dass es ständig Sendungen empfängt.

Wenn Sie wollen nur Sendungen einen Teil der Zeit erhalten, entweder:

• Verwenden registerReceiver() und unregisterReceiver() auf einige Context, wodurch Ihr <receiver> Element aus dem Manifest, oder

• Verwenden PackageManager und setComponentEnabledSetting() zum Aktivieren oder Deaktivieren der <receiver> als geeignet

Als Beispiel für die ersteren this sample app ein Fragment besitzt, die für ACTION_BATTERY_CHANGED in onResume() und hebt die Registrierung in onPause() Register:

     bar.setProgress(pct); 
     level.setText(String.valueOf(pct)); 

     switch (intent.getIntExtra(BatteryManager.EXTRA_STATUS, -1)) {

     default: 
      status.setImageResource(R.drawable.unplugged); 
      break; 
     } 
    } 
    }; 
} 

Als Ergebnis wird es erhält nur diese Sendung während des Fragment im Vordergrund von einem ist Eingabestandpunkt.
