How to Crop Image from Camera and Gallery in Android?
In the previous article, we have discussed how to select an Image from Gallery in Android, but in this project, there is no crop functionality. Sometimes we take pictures on our phone and want to update them as our profile picture. But we need to need to remove the background. So in that case we can use the crop image feature to remove that background and then we can upload that image. A sample video is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language.
Step by Step Implementation
Step 1: Create a New Project
To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.
Step 2: Add dependency to the build.gradle(Module:app) file
Navigate to the Gradle Scripts > build.gradle(Module:app) and add the below dependency in the dependencies section.

Add below lines inside the <application> tag.
Below is the code for the complete AndroidManifest.xml file.
