Answer 1

Your problem is with:

Caused by: java.lang.UnsatisfiedLinkError: Couldn't load lept: findLibrary returned null

You need to include the 'lept' jar and native c++ files in your project and reference them in your build path.

Also, take a look at best OCR (Optical character recognition) example in android
