error when showing the dialog box

The app is running, but then suddenly it stops with the following error message:

Hey Tudor!

What's at lines 69-87 in your LoginActivity file?

Could you please provide them here so that we can take a look?

Thanks in advance! :)

This is what starts at line 69, and the 87 is the function call dialog.show();

ParseUser.logInInBackground(username, password, new LogInCallback() {
                        @Override
                        public void done(ParseUser user, ParseException e) {
                            setSupportProgressBarIndeterminateVisibility(false);

                            if(e == null){
                                // Success
                                Intent intent = new Intent(LoginActivity.this, MainActivity.class);
                                intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                                intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
                                startActivity(intent);
                            } else {
                                AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
                                builder.setMessage(e.getMessage());
                                builder.setTitle(R.string.login_error_title);
                                builder.setPositiveButton(android.R.string.ok, null);

                                AlertDialog dialog = builder.create();
                                dialog.show();
                            }
                        }
                    });

Thanks Tudor!

That code looks fine - it seems as though this is being caused because we're still in a background thread.

Luckily, we can go ahead and run this on the Main UI Thread like this:

runOnUiThread(new Runnable() {
    @Override
    public void run() {
        AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
            builder.setMessage(e.getMessage())
        builder.setTitle(R.string.login_error_title)
        builder.setPositiveButton(android.R.string.ok, null);

            AlertDialog dialog = builder.create();
            dialog.show();
    }
});

Note that you will also need to declare the e variable as final.

Hope it helps and let me know how it goes :)
