I learned that in every project we have only 1 AndroidManifest.xml file. BUT I found two of the same file name !! One is in the root folder, and the other is in the /bin folder...
How come, and what shell I do ?
thx !
project/bin folder is for compiled (to bytecode) source code and project resources.
Do not worry about it, your IDE is handling content of bin folder automaticly. When all code is compilled, your IDE (I think, it is Eclipse) can build your project.
