Ich rufe den Camera Intent in einem verschachtelten Fragment auf und erhalte das Image in onActivityResult im Fragment ohne Probleme. Da ich das Bild zuschneiden möchte, rufe ich eine (zweite) Absicht in onActivityResult auf, um das Bild an den Crop Intent zu übergeben. Das onActivityResult wird in diesem Fall jedoch nicht aufgerufen (Nur relevant, wenn die Anwendung während einer der Absichten im Hintergrund beendet wird).Aufruf des zweiten Intents in onActivityResult des verschachtelten Fragments ruft onActivityResult nicht erneut auf
@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();
}
}
}
fand ich die folgende Zeile in den Protokollen:
W/FragmentActivity: Activity result no fragment exists for who: android:fragment:0:1
Diese nur ausgelöst wird, wenn die Ernte Absicht genannt wird - nicht für die erste Kamera Absicht. Muss ich warten, bis das Fragment erneut erstellt wurde, bevor ich die zweite Absicht anrufe? Oder gibt es einen anderen zuverlässigen Weg, um mit dieser Situation umzugehen? Vielen Dank!

Können Sie Ihren Aktivitätscode angeben? –
@JayminPanchal Ich habe den Aktivitätscode über – mojo
hinzugefügt Sind Sie sicher, dass Sie den cropImage Intent richtig aufrufen? –
