WebAppInterface in WebView does not call onBackPressed

I've a fragment with a WebView inside. I added a custom WebAppInterface that has this method

@JavascriptInterface
public void submitCorrect() {
   Log.d("SUBMIT", "submit");
   getActivity().onBackPressed();
   //getActivity().getFragmentManager().popBackStack();
}

Debugging i saw that the method is called but, I don't know why, neither onBackPressed or popBackStack are working. Any advice?

The problem is, calling the onBackPressed method on WebView Thread, You should call it in the main thread. That's the reason it's not working.

Try changing the code as below:

getActivity().runOnUiThread(new Runnable() {
            @Override
            public void run() {
                getActivity().onBackPressed();
            }
        });

Perhaps finishing the activity instead will work:

@JavascriptInterface
public void submitCorrect() {
   Log.d("SUBMIT", "submit");
   Activity activity = getActivity();
   if (activity != null) 
       activity.finish();
}
