Passing Data from Broadcast Receiver to another Activity

If you have your activity named ReceiveText, then in your BroadcastReceiver, you should do the following:

Intent i = new Intent(context, ReceiveText.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
i.putExtra("message", message.getMessageBody());
context.startActivity(i);

Then, in your activity, you will need to getExtra as so:

Intent intent = getIntent();
String message = intent.getStringExtra("message");

And then you will use message as you need.

If you simply want the ReceiveText activity to show the message as a dialog, declare <activity android:theme="@android:style/Theme.Dialog" /> in your manifest for ReceiveText and then set the message to a textview in the activity.

EDIT: This restarts your activity. this answer is likely a better solution for most people.

1. Instantiate a BroadcastReceiver in the activity you want to get your data to, for example:

   private BroadcastReceiver mServiceReceiver = new BroadcastReceiver(){
       @Override
       public void onReceive(Context context, Intent intent)
       {
           //Extract your data - better to use constants...
           String IncomingSms=intent.getStringExtra("incomingSms");//
           String phoneNumber=intent.getStringExtra("incomingPhoneNumber");
   
       }
   };
   

2. Unregister your receiver on onPause():

   @Override
   protected void onPause() {
       super.onPause();
       try {
           if(mServiceReceiver != null){
           unregisterReceiver(mServiceReceiver);
           }
       } catch (Exception e) {
          e.printStackTrace();
       }
   }
   

3. Register it on onResume():

   protected void onResume() {
       super.onResume();
       IntentFilter filter = new IntentFilter();
       filter.addAction("android.intent.action.SmsReceiver");
       registerReceiver(mServiceReceiver , filter);
   }
   

4. Broadcast your data from the service via an Intent, for Example:

   Intent i = new Intent("android.intent.action.SmsReceiver").putExtra("incomingSms", message);
   i.putExtra("incomingPhoneNumber", phoneNumber);
   context.sendBroadcast(i);
   

and that's it! goodLuck!
