Answer 1

Change

 public void cropImage()
    {
        CropImage.activity()
                .setGuidelines(CropImageView.Guidelines.ON)
                .setMinCropResultSize(512, 512)
                .setAspectRatio(1, 1)
                .getIntent(getContext());
    }

to

 public void cropImage()
    {
        CropImage.activity()
                .setGuidelines(CropImageView.Guidelines.ON)
                .setMinCropResultSize(512, 512)
                .setAspectRatio(1, 1)
                .start(getContext(), this);
    }

So the results will be delivered to the fragment and not to the activity

From Android Image Cropper repository

You can start the CropImageActivity from the fragment and receive the result in the fragment onActivityResult method. Using AppCompat fragment is the best option that allows you to use direct start method:

UPDATE:

Watch this issue in their Git Repository, suggesting another option,

you can get the intent and start the activity manually:

Intent intent = CropImage.activity(imageUri)
   .getIntent(getContext());
startActivityForResult(intent,CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE);

Answer 2

Overide onActivityResult in Activity

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    FragmentManager supportFragmentManager = getSupportFragmentManager();
    Fragment fragmentById = supportFragmentManager.findFragmentById(R.id.container);
    if (fragmentById != null) {
        fragmentById.onActivityResult(requestCode, resultCode, data);
    }
}
