I just started to use DialogFragment from the android support library and find it extremely annoying so far. I have some custom AsyncTasks that are called from different places in my app. There are two occasions when I run into problems with the DialogFragments:
Both, at least I think, are fairly common situations, and in both cases I get a
java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
This is how my AsyncTasks are structured:
private class UploadImageAsyncTask extends AsyncTask<Void, Void, Image> {
private ProgressDialogFragment dialog;
@Override
protected void onPreExecute() {
super.onPreExecute();
FragmentManager fm = getSupportFragmentManager();
dialog = new ProgressDialogFragment();
dialog.show(fm, "ProgressDialogFragment");
}
@Override
protected Image doInBackground(Void... params) {
...
}
@Override
protected void onPostExecute(Image result) {
super.onPostExecute(result);
dialog.dismiss();
...
}
}
}
I know i could set a setting that prevents the screen from going to sleep while debugging and i could set a flag in onActivityResult() and then open the dialog in onStart(), but that is not really what I'm looking for. Are there any better solutions??
Thanks Simon
use dialog.dismissAllowingStateLoss();
instead of dialog.dismiss();
