I am using below version of your library.
com.theartofdev.edmodo:android-image-cropper:2.3.+

Start at CropImageActivity.onCreateOptionsMenu in the stack trace, especially line 87, and inspect how the menu is inflated for version 2.3.+. Reproduce the reported NullPointerException using the supplied stack trace and Android library version. Done means identifying the cause of the null MenuBuilder state and verifying that menu creation no longer crashes.
