Show DialogFragment from onActivityResult

Question

I have the following code in my onActivityResult for a fragment of mine:

onActivityResult(int requestCode, int resultCode, Intent data){
   //other code
   P         


        

Answer 1

It happens because when #onActivityResult() is called, the parent activity has already call #onSaveInstanceState()

I would use a Runnable to "save" the action (show dialog) on #onActivityResult() to use it later when activity has been ready.

With this approach we make sure the action we want to will always work

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == YOUR_REQUEST_CODE) {
        mRunnable = new Runnable() {
            @Override
            public void run() {
                showDialog();
            }
        };
    } else {
        super.onActivityResult(requestCode, resultCode, data);
    }
}

@Override
public void onStart() {
    super.onStart();
    if (mRunnable != null) {
        mRunnable.run();
        mRunnable = null;
    }
}
