Android: got CalledFromWrongThreadException in onPostExecute() - How could it be?

Question

I have an app in production for a few weeks, using ACRA, and I had zero errors until one strange error reported today.

I\'ve got:

    android.view.Vi

Where is

runOnUiThread(new Runnable() {
    public void run() { /*code*/ } );

in your code

/*
             * runs on the ui thread
             */
            protected void onPostExecute(String result) {

                Activity a = getActivity();

                if (S.sHelpEnabled && a != null) {

                    in = new InstructionsView(a.getApplicationContext());

                    runOnUiThread(new Runnable() {
                       public void run() {

                    RelativeLayout mv = (RelativeLayout) a
                            .findViewById(R.id.main_place);

                    mv.addView(in.prepareView());
                   }
                }

            };

Try this code. I think this would fix the problem
