[BUG] - Custom Activity CropImageActivity

[Canato]

Describe the bug
When extending CropImageActivity some methods are running null point exception.

To Reproduce

• Project with this library import
• create a new activity class CustomActivity : CropImageActivity {...}
• Try to run some methods like cropImage() or onBackPressed()

Expected behavior
Custom activity should work as expected

To fix this bug is import we have ability to test in the sample project.
For this, we need to add a new kotlin code that extend the activity
