Sms broadcastreceiver funktioniert nicht in meinem Fragment

Question

Ich habe ein Projekt erstellt, wo die App SMS empfangen kann. Es lief gut, aber als ich versuchte, es zu meinem Hauptprojekt zu implementieren, "würde es nicht funktionieren. Ich versuche, den Broadctreceiver zu meinem Fragment zu implementieren. Ich versuchte Google und verschiedene Foren die meisten von ihnen sagten, dass es die Berechtigungen waren, aber meins bereits gesetzt ist :(. hoffe wirklich, dass ich in dieser Klarheit bekommen.

Mein Fehlerprotokoll dies sagt.

Vielen Dank im Voraus!

Answer 1

Die Lösung war, dass der Code in meiner MainActivity.java gewesen sein sollte. Ich denke, Broadcastreceiver kann nur "von MainActivity und nicht in der Fragment.java aufgerufen werden. Ich legte den Code auf meinem onResume und es funktionierte: D. Meine Textansicht (wo die SMS ich geladen) ist in der Fragment-XML-Datei.

BroadcastReceiver receiver=null; 
 
    @Override 
 
    protected void onResume() { 
 
     super.onResume(); 
 
    
 

 

 
     IntentFilter filter = new IntentFilter("android.provider.Telephony.SMS_RECEIVED"); 
 
     receiver = new BroadcastReceiver() { 
 
      @Override 
 
      public void onReceive(Context arr0, Intent arr1) { 
 
       processReceive (arr0, arr1); 
 

 

 
      } 
 
     }; 
 
     registerReceiver(receiver,filter); 
 

 

 
    } 
 

 
    public void onDestroy() { 
 

 
     super.onDestroy(); 
 
     unregisterReceiver(receiver); 
 

 
    } 
 

 
    public void processReceive (Context context, Intent intent){ 
 

 
     Toast.makeText(context, "You got a message",Toast.LENGTH_LONG).show(); 
 
     TextView lbs = (TextView)findViewById(R.id.textvviewtsmsruta); 
 

 

 
     Bundle bundle = intent.getExtras(); 
 
     Object[] objArr= (Object[])bundle.get("pdus"); 
 
     String sms =""; 
 

 
     for (int i=0;i<objArr.length;i++){ 
 
      SmsMessage smsMsg = SmsMessage.createFromPdu((byte[])objArr[i]); 
 
      String smsBody = smsMsg.getMessageBody(); 
 
      String senderNumber = smsMsg.getDisplayOriginatingAddress(); 
 
      sms +="From: " + senderNumber+"\nContent: "+smsBody+"\n"; 
 
     } 
 
     lbs.setText(sms); 
 

 

 

 
    }
