Likewise the input stream. "ls" is a text-oriented command.

Did you set up the project that generates the JAR as an "Android library
project"?
http://developer.android.com/tools/projects/index.html#LibraryProjects
Did you "create a /libs directory within your Android project directory and

Did you google for an answer?
