title: broadcast Intent / receiver
body: <p>In my Application I have a Broadcast receiver (registered in manifest) class from which I want to send an Intent to MainActivity. Therefore I have another broadcast receiver (dynamically registered) in MainActivity and an Intent Filter. But I don't receive the Intent in Main Activity.
  This is the code:</p>
  
  <pre><code>public class SmsReceiver extends BroadcastReceiver {
  
      public static final String SMS_BUNDLE = "pdus";
  
      public SmsReceiver(){
  
      }
          String TAG = SmsReceiver.class.getSimpleName();
          @Override
          public void onReceive(Context context, Intent intent){
              Bundle bundle = intent.getExtras();
  
              if (bundle != null) {
                  Object[] sms = (Object[]) bundle.get(SMS_BUNDLE);
                  String str = "";
  
                  for (int i=0; i &lt; sms.length; i++) {
              SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) sms[i]);
                      String smsbody = smsMessage.getMessageBody().toString();
                      str += smsbody;
                  }
                  Intent bcIntent = new Intent();
                  bcIntent.setAction("SMS_RECEIVED_ACTION");
                  bcIntent.addCategory(Intent.CATEGORY_DEFAULT);
                  bcIntent.setFlags(Intent.FLAG_RECEIVER_FOREGROUND);
                  bcIntent.putExtra("message", str);
                  context.sendBroadcast(bcIntent);
              }
          }
      }
  </code></pre>
  
  <p>and in the MainActivity:</p>
  
  <pre><code>public class MainActivity extends AppCompatActivity
  {
  public boolean receivedSMS;
  public String displaySMS;
  
    private BroadcastReceiver iReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
      String qqq = intent.getExtras().getString("message");
      info2(intent.getExtras().getString("message"));
      evalMsg(qqq);
    }
  };
  
    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
  
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
  
      graphInit();
      timerInit();
      smnInit();
  
    }
  
    @Override
    protected void onResume(){
  
    super.onResume();
    IntentFilter iFilter = new IntentFilter();
      iFilter.addAction("SMS_RECEIVED_ACTION");
  
      registerReceiver(iReceiver, iFilter);
  
    }
  
    @Override
    protected void onPause(){
      unregisterReceiver(iReceiver);
      super.onPause();
    }
  </code></pre>
  
  <p>Does anyone know why the broadcast receiver in the main activity doesnt receive the intent? There should be a text displayed in the TextView but it is never shown. thanks for any idea</p>
