how many files can we put in the data folder?

Hello,

I'm trying to export a signed package and I have this problem : when I have 78 files (gif, jpg, mp3) in the data folder (less than 5Mb), the app is created. But when I have more than 78 files, the process doesn't go to its end and no error message is given. It's not due to a file in particular (I tried with different files).

Does anyone have an idea about how fixing this?

Thanks a lot for your help! Jim Rolland

PS : I work on windows 7, processing 2.2.1, Android Studio 1.3.2 and SDK manager API 19.
