Android app crop an image and send it to another activity

Question

I'm creating an android app where the user crops the image, the cropped image is shown and then has to be sent in the Result activity.

The problem I have is that when I send the image, it sends me the original uncropped image.

So I wonder, am I wrong something or the image is not really cropped?

Can anyone help me figure out how to display the cropped image in the Result activity?

Thank you so much for your help guys.

onActivityResult

@Override
    protected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
         if (requestCode == UCrop.REQUEST_CROP && resultCode == RESULT_OK) {
            if (data != null) {
                Uri uri = UCrop.getOutput(data);
                showImage(uri);
            }
        } else if (requestCode == PICK_IMAGE_GALLERY_REQUEST_CODE && resultCode == RESULT_OK && data != null) {
            try {
                Uri sourceUri = data.getData();
                File file = getImageFile();
                Uri destinationUri = Uri.fromFile(file);
                openCropActivity(sourceUri, destinationUri);


                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(),sourceUri);

                imageView.setImageBitmap(bitmap);

            } catch (Exception e) {
                uiHelper.toast(this, "Please select another image");
            }
        }
    }

Crop method

private void openCropActivity(Uri sourceUri, Uri destinationUri) {
        UCrop.Options options = new UCrop.Options();
        options.setCropFrameColor(ContextCompat.getColor(this, R.color.colorAccent));
        UCrop.of(sourceUri, destinationUri)
                .withMaxResultSize(1080, 540)
                .withAspectRatio(16, 9)
                .start(this);
    }

show ImageCropped on MainActivity

private void showImage(Uri imageUri) {
        try {
            File file;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.KITKAT) {
                file = FileUtils.getFile(this, imageUri);
            } else {
                file = new File(currentPhotoPath);
            }
            InputStream inputStream = new FileInputStream(file);
            Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
            imageView.setImageBitmap(bitmap);
        } catch (Exception e) {
            uiHelper.toast(this, "Please select different profile picture.");
        }

            star.setImageBitmap(b);
            previewThumbnail.setImageBitmap(b);

        }

Instead of passing bitmap you should pass cropped image path to new activity. — Piyush, Jun 26 '19 at 10:50
but where do I write the code with intent? in the resultActivity? — Marie Hopkin, Jun 26 '19 at 12:41
I looked at this but I can't send the uri https://stackoverflow.com/questions/28348722/how-to-transfer-a-uri-image-from-one-activity-to-another/28354078 — Marie Hopkin, Jun 26 '19 at 12:48
and this, but don't work for me https://stackoverflow.com/questions/32664505/pass-uri-to-another-activity-and-convert-it-to-image?lq=1 — Marie Hopkin, Jun 26 '19 at 12:48

In _showImage()_ function declare _File file;_ as global. Now in _vaiii_ function write *Intent i = new Intent(this, risult.class); i.putExtra("imagePath", file.getAbsolutePath()); startActivity(i);* — Piyush, Jun 26 '19 at 12:54
I can't declare it global, that is I declare it in the activity complement but when I declare it inside the function ShowImage () is not global — Marie Hopkin, Jun 26 '19 at 13:20
yes I did, but it gives me the error `'java.lang.String java.io.File.getAbsolutePath()' on a null object reference` — Marie Hopkin, Jun 26 '19 at 13:23
no, that's why it didn't work, now it works, thanks a lot. If you answer me, the answer is correct — Marie Hopkin, Jun 26 '19 at 13:25
