Sometimes for file size optimization or just for making an image to fit a specific image view, a lot of applications need to handle the image cropping feature. This, unlike other implementation of widgets, can be pretty easy using a third party library.
In this top, we'll share with you 10 of the most imponent libraries to build image croppers in your native android application.

This is a lightweight Image Cropper for Android which also supports no-crop feature. It's a FrameLayout which contains a view for Grid and an imageview. This project supports only square cropping. CropperView contains some basic methods like setImageBitmap(), setMaxZoom(), setMinZoom(), etc which are forwarded to CropperImageView.
It's not an Activity or Fragment. It's just a FrameLayout which you can use anywhere and however you want in your app. There are some styling and customizations also available.

2. Android Image Cropper

But if you do want the resulting image pixels to reflect the oval shape you can use CropImage.toOvalBitmap(Bitmap) helper method that does exactly that.
