Java Silent Fail

[Gary Adams]

Don't worry about the "unused DT entry" warnings.
Those are just VERNEED entries in the libraries,
that are not used on android.

I presume the executable and libraries are installed OK,
since the warnings below indicate they were found.

I assume the target android api is compatible with the
runtime device or emulator you are using.

Note that the use of java on the command line (adb shell)
is just a smoke test that the build was complete.
The real test of the libraries is when they've been
incorporated in an apk and installed as an app.
