android.view.WindowManager$BadTokenException: Unable to add window is not valid; is your activity running?

Question

I try to add dialog in my activity, but in vain, Following is my code.

    private void saveMissionFile() {
    final String defaultFilename = TextUtils.isEmpty(openedMissionFilename)
            ? FileStream.getWaypointFilename("waypoints")
            : openedMissionFilename;

    final SupportEditInputDialog dialog = SupportEditInputDialog.newInstance(MISSION_FILENAME_DIALOG_TAG,
            getString(R.string.label_enter_filename), defaultFilename, true);
 //       dialog.show(getSupportFragmentManager(), MISSION_FILENAME_DIALOG_TAG);

    dialog.show(MyFirstPlanFirstActivity.this.fragmentManager, MISSION_FILENAME_DIALOG_TAG);


}

After I implement app, I got this error than app crushed, what can I do?

It works for me, new AlertDialog.Builder(getParent()) .setTitle(R.string.choose_map_tile) .setView(v1) ...... } }) .show(); — Beatrice Lin, Mar 21 '17 at 06:42
I'm not sure what parameter I should put in dialog.show function. — Beatrice Lin, Mar 21 '17 at 06:46
