hi new android app development , trying implement simple ocr app found here: https://github.com/gautamgupta/simple-android-ocr using android studio, found errors had permission fixed getting error:

so if need post thing else please tell me , in advance!

@gabesechan right went through app files , there supposed file name, doing further google search learnt that file supposed generated when building tess-two library used in app, think didn't right. thank much.
