问题
I am implementing dark mode on my app, and I am facing a peculiar(to me) problem. Below is the logcat of the crash, which I am facing only in dark mode, no error/warning in Light/Default (I am in SDK<=29, so my default is battery saver) mode. Even when battery saver is on, i.e. the app is essentially in dark mode, this crash does not occur.
Log of the error:

This crash is happening only when (with explicit dark mode), when I am calling this (called in MainActivity, not in the Fragment):
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_searchplace:
onSearchCalled();
return true;
....
*other cases does not show this error*
...
}
public void onSearchCalled() {
// Set the fields to specify which types of place data to return.
List<Place.Field> fields = Arrays.asList(Place.Field.ID, Place.Field.NAME, Place.Field.ADDRESS, Place.Field.LAT_LNG);
// Start the autocomplete intent.
Intent intent = new Autocomplete.IntentBuilder(
AutocompleteActivityMode.OVERLAY, fields) //no .setCountry...Search whole world
.build(this);
startActivityForResult(intent, AUTOCOMPLETE_REQUEST_CODE);
}
@Override
protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == AUTOCOMPLETE_REQUEST_CODE) {
if (resultCode == RESULT_OK) {
Place place = Autocomplete.getPlaceFromIntent(data);
if (place.getLatLng() !=null) {
Lat = place.getLatLng().latitude;
Long = place.getLatLng().longitude;
// Toast.makeText(MainActivity.this, ""+Lat, Toast.LENGTH_LONG).show();
setupViewPager();
} else {
Toast.makeText(this, getString(R.string.location_not_found), Toast.LENGTH_LONG).show();
}
} else if (resultCode == AutocompleteActivity.RESULT_ERROR) {
// TODO: Handle the error.
Status status = Autocomplete.getStatusFromIntent(data);
Toast.makeText(MainActivity.this, "Error: " + status.getStatusMessage(), Toast.LENGTH_LONG).show();
// Log.i("LocationSearch", status.getStatusMessage());
}
}
and I have explicitly called for checking night mode in my fragments, like:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);
} else {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_AUTO_BATTERY);
}
SharedPreferences sharedPref = PreferenceManager.getDefaultSharedPreferences(mContext);
// AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
String theme = sharedPref.getString("theme", "Default");
// Toast.makeText(this, theme, Toast.LENGTH_LONG).show();
if (theme.equals("Dark")) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
} else if (theme.equals("Light")) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
} else {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_FOLLOW_SYSTEM);
} else {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_AUTO_BATTERY);
}
}
// Inflate the layout for this fragment
View rootView = inflater.inflate(R.layout.fragment_sun, container, false);
....
....
@Override
public void onAttach(@NonNull Context context) {
super.onAttach(context);
mContext = context;
}
I need this checking because, if I don't put this, then the cards of this fragment is light on start. I also have this code in MainActivity's onCreate, but that is not creating any error.
I am totally confused why I am getting this. Kindly help.
