A simple Android image cropper library using canvas.

• Just for learning canvas in Android
• Build a library project
• An image cropper for future use, alternative to Android image cropper.

• Custom aspect for cropped image (now only as square)
• Cropped image with higher resolution (now it's still depend on how ImageView can handle)

First declare CropActivity in your manifest file:

<activity android:name="gdg.ninja.croplib.CropActivity" >

###Crop

new Crop(inputUri).output(outputUri).quality(90).withMaxSize(maxWidth, maxHeight).start(activity);

Listen for the result of the crop:

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data){
	if(resultCode == RESULT_OK){
		if(requestCode == Crop.REQUEST_CROP){
			Uri croppedImageUri = data.getData();
			//DO SOMETHING WITH croppedImageUri
		}
	}
}
