Get Intent
Hi, I’ve been trying to use this library alongside with RxPermission and RxActivityResult. For that you need to obtain the Intent to run and that’s currently not possible, you can only launch it directly.
For now what I’ve done is to create my own camera and gallery intent and then attach the bundle to the imagepicker.
What could be the best approach to obtain the intent from the imagepicker?
Thank you
new RxPermissions(getActivity()).request(Manifest.permission.WRITE_EXTERNAL_STORAGE)
.flatMap(new Function<Boolean, ObservableSource<Result<VendaStepPhotosFragment>>>() {
@Override
public ObservableSource<Result<VendaStepPhotosFragment>> apply(Boolean aBoolean) throws Exception {
if (aBoolean) {
Intent intent = new Intent("android.intent.action.GET_CONTENT");
intent.setType("image/*");
return RxActivityResult.on(VendaStepPhotosFragment.this).startIntentSender(PendingIntent.getActivity(getActivity(), Picker.PICK_IMAGE_CAMERA, intent, 0).getIntentSender(), new Intent(), Integer.valueOf(0), Integer.valueOf(0), Integer.valueOf(0));
} else {
return Observable.error(new PermissionException());
}
}
})
.subscribe(new Consumer<Result<VendaStepPhotosFragment>>() {
@Override
public void accept(Result<VendaStepPhotosFragment> result) throws Exception {
if (result.resultCode() != Activity.RESULT_OK) {
Toast.makeText(getContext(), "Cancel!", Toast.LENGTH_SHORT).show();
} else {
imagePicker.submit(result.data());
}
}
});
I can write a helper method to provide you with the proper intents when you need. Would that work?
Hi! I got the crash:

I have implemented an internal class inheriting from ImagePickerImpl so that I can get the Intent temporarily. I build the Intent similarly pickLocalImage method in ImagePickerImpl class, so I don't understand the bug...
Thanks!
public class GetGalleryImageCase extends UseCase<List<ChosenImage>> {
private Fragment fragment;
private final MyImagePickerImpl imagePicker;
public GetGalleryImageCase(Context context, Fragment fragment) {
super(context);
this.fragment = fragment;
imagePicker = new MyImagePickerImpl(fragment);
}
@Override
public Observable<List<ChosenImage>> getObservable() {
return new RxPermissions(fragment.getActivity()).request(Manifest.permission.MANAGE_DOCUMENTS, Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE)
.flatMap(new Function<Boolean, ObservableSource<Result<Fragment>>>() {
@Override
public ObservableSource<Result<Fragment>> apply(Boolean aBoolean) throws Exception {
if (aBoolean) {
return RxActivityResult.on(fragment).startIntent(imagePicker.getIntent());
} else {
return Observable.error(new PermissionException());
}
}
})
.flatMap(new Function<Result<Fragment>, ObservableSource<List<ChosenImage>>>() {
@Override
public ObservableSource<List<ChosenImage>> apply(final Result<Fragment> result) throws Exception {
if (result.resultCode() != Activity.RESULT_OK) {
return Observable.error(new CaptureImageCanceledException());
} else {
return Observable.create(new ObservableOnSubscribe<List<ChosenImage>>() {
@Override
public void subscribe(final ObservableEmitter<List<ChosenImage>> e) throws Exception {
imagePicker.setImagePickerCallback(new ImagePickerCallback() {
@Override
public void onImagesChosen(List<ChosenImage> list) {
e.onNext(list);
e.onComplete();
}
@Override
public void onError(String s) {
e.onError(new CaptureImageErrorException(s));
}
});
imagePicker.submit(result.data());
}
});
}
}
});
}
private static class MyImagePickerImpl extends ImagePickerImpl {
public MyImagePickerImpl(Fragment fragment) {
super(fragment, Picker.PICK_IMAGE_DEVICE);
}
protected Intent getIntent() throws PickerException {
Intent intent = new Intent("android.intent.action.GET_CONTENT");
intent.setType("image/*");
if(this.extras != null) {
intent.putExtras(this.extras);
}
if(this.allowMultiple && Build.VERSION.SDK_INT >= 18) {
intent.putExtra("android.intent.extra.ALLOW_MULTIPLE", true);
}
return intent;
}
}
}
From where you are choosing the image? Also, can you provide a sample app for me to debug the issue?
Hi! Here you have a sample project to debug the issue: https://github.com/CristianMG/MultipickerRxJavaSample
Thanks!
if treatment URI with this line the function is correctly, I think that the bug comes from RxResult library because URI don't have permissions. fragment.getContext().grantUriPermission(fragment.getActivity().getPackageName(), result.data().getData(), Intent.FLAG_GRANT_READ_URI_PERMISSION);
Hi, I also got the same crash, while pick image from gallery in android 5.1.1
