Crop image after picking up from gallery android

Question

Want to crop image after user picks image from the Gallery.

So basically when user selects image from gallery, he should be able to crop it and when he clicks ok, image should get sent to server.

On button click, I have this code which launches gallery.

Intent intent = new Intent(Intent.ACTION_PICK);
intent.setType("image/*");
startActivityForResult(intent,RESULT_TRUE);

Then I have this code which select image from gallery and upload it to firebase.

@Override
    public  void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == RESULT_TRUE && resultCode == RESULT_OK) {
            dialog.show();
            Uri url = data.getData();
            StorageReference filepath = mstorage.child("photos").child(url.getLastPathSegment());
            filepath.putFile(url).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
                @Override
                public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
                    Toast.makeText(getContext(), "upload done", Toast.LENGTH_LONG).show();
                    Uri downloadurl = taskSnapshot.getDownloadUrl();
                    String imageUrl = downloadurl.toString();
                    Glide.with(getContext()).load(imageUrl).centerCrop().placeholder(R.drawable.ic_menu_camera).crossFade().into(mImage1);
                    SubscriberService subscriberService = new SubscriberService();
                    subscriberService.addItemChildList(AddImagesFragment.this, mAuth.getCurrentUser().getUid(), "images", imageUrl, place);
                    } catch (UnsupportedEncodingException e) {
                        e.printStackTrace();
                    } catch (JSONException e) {
                        e.printStackTrace();
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            });
        }

Can someone please help me with the code to crop image.

Thanks

Answer 1

Have a look at this library , May be you will get a proper solution.

Add uCrop to your Gradle first, than To use it write this onActivityResult,

case IMAGE:
    UCrop.of(data.getData(), Uri.fromFile(new File(this.getCacheDir(), "IMG_" + System.currentTimeMillis())))
                    .start(YourActivity.this);
break;

After that handle uCrop Result in onActivityResults as (You can take a switch case to handle multiple requestcodes over there):

                 case UCrop.REQUEST_CROP:
                    Uri imgUri = UCrop.getOutput(data);
                    if (imgUri != null) {
                        String selectedImage = imgUri.getPath();

                       // load selectedImage into ImageView
                    } else {
                        Snackbar.make(view, R.string.str_bad_image_file, Snackbar.LENGTH_LONG)
                                .show();
                    }
                    break;
                case UCrop.RESULT_ERROR:
                    Snackbar.make(view, R.string.str_bad_image_file, Snackbar.LENGTH_LONG)
                            .show();
                    break;

You can use this method to perform crop:-

private void performCrop(String picUri) {
        try {
            //Start Crop Activity

            Intent cropIntent = new Intent("com.android.camera.action.CROP");
            // indicate image type and Uri
            File f = new File(picUri);
            Uri contentUri = Uri.fromFile(f);

            cropIntent.setDataAndType(contentUri, "image/*");
            // set crop properties
            cropIntent.putExtra("crop", "true");
            // indicate aspect of desired crop
            cropIntent.putExtra("aspectX", 1);
            cropIntent.putExtra("aspectY", 1);
            // indicate output X and Y
            cropIntent.putExtra("outputX", 280);
            cropIntent.putExtra("outputY", 280);

            // retrieve data on return
            cropIntent.putExtra("return-data", true);
            // start the activity - we handle returning in onActivityResult
            startActivityForResult(cropIntent, RESULT_CROP);
        }
        // respond to users whose devices do not support the crop action
        catch (ActivityNotFoundException anfe) {
            // display an error message
            String errorMessage = "your device doesn't support the crop action!";
            Toast toast = Toast.makeText(this, errorMessage, Toast.LENGTH_SHORT);
            toast.show();
        }
    }

Look at this library. It provide basic cropping functionality and used by lots of people

Answer 4

This is a well tested code, so it will definitely work. Try to use below code, for cropping the image:
private CropImageView img_crop;
private int CROP_RESULT = 3;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_crop_);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    toolbar.setNavigationIcon(R.drawable.back_white);
    toolbar.setNavigationOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onBackPressed();
        }
    });
    img_crop = (CropImageView) findViewById(R.id.img_crop);
    img_crop.setInitialFrameScale(0.75f);

    img_crop.setAnimationEnabled(true);
    img_crop.setAnimationDuration(300);
    img_crop.setCropMode(CropImageView.CropMode.RATIO_3_4);
    configureDefaultImageLoader(Crop_Activity.this);
    Intent intent = getIntent();
    Bundle b = intent.getExtras();
    String path = " ";
    final String type = b.getString("type");
    path = b.getString("BitmapImage");
    Log.e("Crop_Uri>>", path.toString());
    {
        try {
            InputStream image_stream = null;

            image_stream = getContentResolver().openInputStream(Uri.parse("file://" + path.toString()));
            Bitmap bitmap1 = BitmapFactory.decodeStream(image_stream);
            if (bitmap1 != null) {
                bitmap1.recycle();
                bitmap1 = null;
            }
            ImageLoader.getInstance().displayImage(ImageDownloader.Scheme.FILE.wrap(path.toString()), img_crop);
            //  img_crop.setImageBitmap(bitmap1);
            Log.e("Image//", "//" + "yes");
        } catch (Exception e) {
            //handle exception
            Log.e("ExceptionImage>>", "//" + e);
        }
    }


    FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
    fab.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
          /*  Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                    .setAction("Action", null).show();*/
            if (img_crop.getImageBitmap() != null) {
                Bitmap crop_bitmap = img_crop.getCroppedBitmap();
                ByteArrayOutputStream stream = new ByteArrayOutputStream();

                File dest = new File(getFilename());
                try {
                    FileOutputStream out = new FileOutputStream(dest);
                    crop_bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);
                    out.flush();
                    out.close();
                } catch (Exception e) {
                    e.printStackTrace();
                }
                byte[] byteArray = stream.toByteArray();

                Intent intent = new Intent();
                intent.putExtra("croped_bitmap_uri", dest.getAbsolutePath());
                intent.setAction("ok");
                setResult(CROP_RESULT, intent);
                deleteFile();
                finish();
            } else {
                Toast.makeText(Crop_Activity.this, "Crop Images Not Processed !", Toast.LENGTH_SHORT).show();
            }

        }
    });
}

public String getFilename() {
    File myDirectory = new File(Environment.getExternalStorageDirectory(), "Konnect_Mom/Konnect_Mom_cropped_img");
    if (!myDirectory.exists()) {
        myDirectory.mkdirs();
    }

    String timeStamp = new SimpleDateFormat("ddMMyyyy_HHmm").format(new Date());
    String mImageName = "cropped_img" + ".jpg";
    String uriSting = (myDirectory.getAbsolutePath() + "/" + mImageName);
    return uriSting;

}

public void deleteFile() {
    File file = new File(Environment.getExternalStorageDirectory() + "Konnect_Mom/Konnect_Mom_cropped_img/cropped_img.jpg");
    if (file.exists()) {

        file.delete();
    }

}

public static void configureDefaultImageLoader(Context ctx) {
    ImageLoaderConfiguration config = new ImageLoaderConfiguration.Builder(ctx).threadPriority(Thread.NORM_PRIORITY - 2).denyCacheImageMultipleSizesInMemory().diskCacheFileNameGenerator(new Md5FileNameGenerator()).tasksProcessingOrder(QueueProcessingType.FIFO).build();
    ImageLoader.getInstance().init(config);
    DisplayImageOptions defaultOptions = new DisplayImageOptions.Builder()
            .cacheInMemory(true)
            .cacheOnDisk(true)
            .showImageOnLoading(android.R.drawable.stat_sys_download)
            .showImageForEmptyUri(android.R.drawable.ic_dialog_alert)
            .showImageOnFail(android.R.drawable.stat_notify_error)
            .considerExifParams(true)
            .bitmapConfig(Bitmap.Config.RGB_565)
            .imageScaleType(ImageScaleType.EXACTLY_STRETCHED) //filled width
            .build();
}

}

Just copy the above code and paste it in a class titled "CropActivity". After that in the activity where you open "Camera" or "Gallery" to fetch images, place the below code inside the "onActivityResult()" method:

 Intent i = new Intent(AddAChild.this, Crop_Activity.class);
                i.putExtra("BitmapImage", filename);
               startActivityForResult(i, CROP_RESULT);

That's it. Your good to go.
