Update Fragment Ui With Data Passed From Activity

My Requirement : My MainActivity receives data from other app. MainActivity is listed as shareable. Now, I need to pass this data to a fragment in MainActivity and update the fragm

Solution 1:

Just add a proper method in your fragment, something like this:

publicvoidreceiveURL(String input){
//to handle what you want to pass to the fragment
}

And in your mainActivity call you can do something like this:

YourFragmentfragment= (YourFragment)getSupportFragmentManager.findFragmentById(R.id.your_fragment);
fragment.receive(sharedUrl);

Solution 2:

I'm assuming you already added the fragment via fragmentManager.add(..) so the fragment is already on the layout.

If this is true, then your AddTab fragobj = new AddTab() makes no sense since the Fragment already exists.

You need to either store a reference to this fragment in the activity, or use fragmentManager.findFragmentById() or findFragmentByTag().
