Passing Data Though Multiple Activities

1- is my first activity(main) 2- is my second activity 3 - is my third activity I want to run 2 from 1 and then form 2 run 3 , and then from 3 i am taking data and returning it to

Solution 1:

You cannot do this when starting 2 from 1:

Intent intent = newIntent(getApplicationContext(), MessageBox.class);
intent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
startActivityForResult(intent,5);

This will throw the exception you are getting. You cannot use FLAG_ACTIVITY_FORWARD_RESULT and startActivityForResult() together.

If you want 1 to get the result from 3, then you need to start 2 from 1 like this:

Intent intent = newIntent(getApplicationContext(), MessageBox.class);
startActivityForResult(intent, 5);

and then start 3 from 2 like this:

Intent intent = newIntent(getApplicationContext(), ImageReceiver.class);
intent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);
startActivity(intent);
finish();

This tells Android that activity 3 (ImageReceiver) should forward its result back to the activity that called activity 2 (MessageBox). When activity 3 sets its result and finishes, onActivityResult() in activity 1 will be called with the result data sent from activity 3.

Solution 2:

comment out this line in activity 1

intent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT);

and this line in activity 2

Intent intent = newIntent(getApplicationContext(),MainActivity.class);

You should be all set.
