• 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)

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

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 the Library

There is 3 ways of using the library:

• Calling crop directly (Sample code: sample/crop_image)
• Using the CropView (Sample code: sample/crop_image_view)
• Extending the activity (Sample code: sample/extend_activity)
  Your choice depends on how you want your layout to look.

Obs: The library has a public pick image contract, more on wiki.

Calling crop directly

• Register for activity result with CropImageContract

class MainActivity {
   private val cropImage = registerForActivityResult(CropImageContract()) { result ->
           if (result.isSuccessful) {
               // use the returned uri
               val uriContent = result.uriContent 
               val uriFilePath = result.getUriFilePath(context) // optional usage
           } else {
               // an error occurred
               val exception = result.error
           }
       }

   private fun startCrop() {
       // start picker to get image for cropping and then use the image in cropping activity
       cropImage.launch(
           options {
               setGuidelines(Guidelines.ON)
           }
       )

       //start picker to get image for cropping from only gallery and then use the image in
       //cropping activity
       cropImage.launch(
           options {
               setImagePickerContractOptions(
                   PickImageContractOptions(includeGallery = true, includeCamera = false)
               )
           }
       )

       // start cropping activity for pre-acquired image saved on the device and customize settings
       cropImage.launch(
           options(uri = imageUri) {
               setGuidelines(Guidelines.ON)
               setOutputCompressFormat(CompressFormat.PNG)
           }
       )
   }
}

Using CropView

2. Add CropImageView into your activity

<!-- Image Cropper fill the remaining available height -->
<com.canhub.cropper.CropImageView
  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
val cropped: Bitmap = cropImageView.getCroppedImage()

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)
}
