Using the Library

There are 3 ways of using the library. Check out the sample app for all details.

1. Calling crop directly

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)
      }
    )
  }
}

2. Using CropView

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"
  />

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.
val cropped: Bitmap = cropImageView.getCroppedImage()

3. Extend to make a custom activity

If you want to extend the CropImageActivity please be aware you will need to set up your CropImageView

Add CropImageActivity into your AndroidManifest.xml

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

Set up your CropImageView after call super.onCreate(savedInstanceState)

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

Custom dialog for image source pick

When calling crop directly the library will prompt a dialog for the user choose between gallery or camera (If you keep both enable). We use the Android default AlertDialog for this. If you wanna customised it with your app theme you need to override the method showImageSourceDialog(..) when extending the activity (above)

override fun showImageSourceDialog(openSource: (Source) -> Unit) {
  super.showImageSourceDialog(openCamera)
}

Android cropping image from camera or gallery

Migrating from Android Image Cropper

Start by using Version 4.3.3:

dependencies {
  implementation("com.vanniktech:android-image-cropper:4.3.3")
}

Update all imports

-import com.theartofdev.edmodo.cropper.CropImage
-import com.theartofdev.edmodo.cropper.CropImageActivity
+import com.canhub.cropper.CropImage
+import com.canhub.cropper.CropImageActivity

Update all XML references

-<com.theartofdev.edmodo.cropper.CropImageView
+<com.canhub.cropper.CropImageView

When using Activity Contracts, consult with the sample app on how to use our Activity Contracts since onActivityResult got deprecated.

Versions after 4.3.3 have changed the APIs quite a bit, it's best to upgrade to each minor version individually, remove deprecated API usages and continue upgrading. So after using 4.3.3, upgrade to 4.4.0, etc.
