Я вызываю намерение камеры во вложенном фрагменте и без проблем получаю изображение в onActivityResult во фрагменте. Поскольку я хочу обрезать изображение, я вызываю (второе) намерение в onActivityResult передать изображение в намерение Crop. Тем не менее, onActivityResult не вызывается в этом случае (Только релевантно, если приложение завершается в фоновом режиме во время одного из намерений).Вызов второго намерения в onActivityResult вложенного фрагмента не вызовет onActivityResult снова
@Override
public void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
super.onActivityResult(requestCode, resultCode, imageReturnedIntent);
switch (requestCode) {
// Camera onActivityResult
case INTENT_CAMERA:
Toast.makeText(getActivity(), "IN CARD ONACTIVITY - CAMERA INTENT", Toast.LENGTH_LONG).show();
if (resultCode == RESULT_OK) {
SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences(getActivity());
String uriString = getPrefs.getString("photoUri", null);
if (uriString != null) {
Uri selectedImage = Uri.parse(uriString);
Intent intent = CropImage.activity(selectedImage).setAspectRatio(1, 1).setMinCropResultSize(800, 800).getIntent(getContext());
startActivityForResult(intent, INTENT_CROP);
} else {
Toast.makeText(getActivity(), "ERROR", Toast.LENGTH_LONG).show();
}
}
break;
// Crop ActivityOnResult
case INTENT_CROP:
Toast.makeText(getActivity(), "IN CARD ONACTIVITY - CROP INTENT", Toast.LENGTH_LONG).show();
CropImage.ActivityResult result = CropImage.getActivityResult(imageReturnedIntent);
if (resultCode == RESULT_OK) {
Uri resultUri = result.getUri();
try {
bitmap = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), resultUri);
uploadImage();
} catch (IOException e) {
e.printStackTrace();
}
} else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
Exception error = result.getError();
}
}
}
я нашел следующую строку в журналах:
W/FragmentActivity: Activity result no fragment exists for who: android:fragment:0:1
Это только бросили, когда цель урожая называется - не для первого намерения камеры. Должен ли я ждать, пока фрагмент будет создан снова, прежде чем вызывать второе намерение? Или есть ли другой надежный способ справиться с этой ситуацией? Спасибо!

Вы можете указать код своей деятельности? –
@JayminPanchal Я добавил код активности выше – mojo
, вы уверены, что правильно вызвали намерение cropImage? –
