Android Image Cropper

:triangular_flag_on_post: The Project is NOT currently maintained :triangular_flag_on_post:

Please use CanHub's fork!

Thank everybody for using the library. It was very fun to create and a privilage to help you build awesome apps.

The same way I took an unmaintained initial implementation from edmodo, I'm happy to see CanHub taking it now.

Good luck and happy coding :octocat:

Powerful (Zoom, Rotation, Multi-Source), customizable (Shape, Limits, Style), optimized (Async, Sampling, Matrix) and simple image cropping library for Android.

Usage

For a working implementation, please have a look at the Sample Project

See GitHub Wiki for more info.

1. Include the library

dependencies {
    api 'com.theartofdev.edmodo:android-image-cropper:2.8.+'
}

Add permissions to manifest

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Add this line to your Proguard config file

-keep class androidx.appcompat.widget.** { *; }

Using Activity

2. Add CropImageActivity into your AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
  android:theme="@style/Base.Theme.AppCompat"/> <!-- optional (needed if default theme has no action bar) -->

3. Start CropImageActivity using builder pattern from your activity

// start picker to get image for cropping and then use the image in cropping activity
CropImage.activity()
  .setGuidelines(CropImageView.Guidelines.ON)
  .start(this);

// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
 .start(this);

// for fragment (DO NOT use `getActivity()`)
CropImage.activity()
  .start(getContext(), this);

4. Override onActivityResult method in your activity to get crop result

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
  if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
    CropImage.ActivityResult result = CropImage.getActivityResult(data);
    if (resultCode == RESULT_OK) {
      Uri resultUri = result.getUri();
    } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
      Exception error = result.getError();
    }
  }
}

Using View

2. Add CropImageView into your activity

<!-- Image Cropper fill the remaining available height -->
<com.theartofdev.edmodo.cropper.CropImageView
  xmlns:custom="http://schemas.android.com/apk/res-auto"
  android:id="@+id/cropImageView"
  android:layout_width="match_parent"
  android:layout_height="0dp"
  android:layout_weight="1"/>

3. Set image to crop

cropImageView.setImageUriAsync(uri);
// or (prefer using uri for performance and better user experience)
cropImageView.setImageBitmap(bitmap);

4. Get cropped image

// subscribe to async event using cropImageView.setOnCropImageCompleteListener(listener)
cropImageView.getCroppedImageAsync();
// or
Bitmap cropped = cropImageView.getCroppedImage();
