Sms broadcastreceiver isn't working in my fragment

Question

I created a project where the app can receive sms. It went well but when i tried to implement it to my Main project" it wouldn't work. I'm trying to implement the broadcastreceiver to my fragment. I tried google and different forums most of them said it was the permissions, but mine is already set :(. Really hope i can get some clarity in this.

My error log says this.

My fragment

Thank you all in advance!

Answer 1

The solution was that the code should have been in my MainActivity.java . I think broadcastreceiver only can be "called from MainActivity and not in the fragment.java. I put the code on my onResume and it worked :D. My textview (where the sms i loaded) is in the fragments xml file.

 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); }
