[Galaxy S 4 i9505 Original Android Development] fefuzzo:
Ok thanks for the answer!

i'm trying to build from source, and now i stopped during the build of the android app:

i make this command with no problem

cmake .. -DMBP_BUILD_TARGET=android -DMBP_BUILD_TYPE=debug

but then i use make command and this was the error:
