If you want to use a library, you can implement this library. And follow this code

From ArthurHub/Android-Image-Cropper

AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
android:theme="@style/Base.Theme.AppCompat"/> <!-- optional (needed if default theme has no action bar) -->

To start CropImageActivity

// start picker to get image for cropping and then use the image in cropping 
activity
CropImage.activity()
         .setGuidelines(CropImageView.Guidelines.ON)
         .start(this);

// start cropping activity for pre-acquired image saved on the device
CropImage.activity(imageUri)
         .start(this);

// for fragment (DO NOT use `getActivity()`)
CropImage.activity()
         .start(getContext(), this);

Override onActivityResult

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
           Uri resultUri = result.getUri();
        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
          Exception error = result.getError();
        }
      }
    }
