Contributing Guide

Android Image Cropper

Powerful (Zoom, Rotation, Multi-Source); Customizable (Shape, Limits, Style); Optimized (Async, Sampling, Matrix); Simple image cropping library for Android.

Add to your project

See GitHub Wiki for more info.

Step 1. Add the JitPack repository to your root build.gradle

  allprojects {
     repositories {
       ....
       maven { url 'https://jitpack.io' }
     }
  }

Step 2. Add the dependency

  dependencies {
       implementation 'com.github.CanHub:Android-Image-Cropper:${version}'
  }

Latest Release Version

Step 3. Add permissions to manifest

Only need if you run on devices under OS10 (SDK 29)

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"
                android:maxSdkVersion="28" />

Step 4. Add this line to your Proguard config file

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

Step 5. Set source compatibility version to Java 8

Go to app level build.gradle file

Add this line inside android in build.gradle

 compileOptions {
     sourceCompatibility JavaVersion.VERSION_1_8
     targetCompatibility JavaVersion.VERSION_1_8
 }

This will set the java version to 8

Using Activity

Extend to make a custom activity

If you want to extend the CropImageActivity please be aware you will need to setup your CropImageView You can check a sample code in this project com.canhub.cropper.sample.extend_activity.app.ExtendActivity

Add CropImageActivity into your AndroidManifest.xml

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

Setup your CropImageView after call super.onCreate(savedInstanceState)

override fun onCreate(savedInstanceState: Bundle?) {
 super.onCreate(savedInstanceState)
 setCropImageView(binding.cropImageView)
}

Start the default Activity

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);

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

Add CropImageView into your activity

<!-- Image Cropper fill the remaining available height -->
<com.canhub.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"/>

Set image to crop

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

Get cropped image

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