Create simple Android application to execute filter as subprocess about diamond-android

[bamos]

I can run dog_filter from Android by pushing the ARM executable to my device.
/sdcard isn't executable, so on my rooted phone, I'm able to copy
dog_filter to /data/ and execute it.
It shows the output from a simple printf statement
I added in lib_filter.h.

Next, I think I'll be able to do this on an unrooted phone
since actual Android applications have their own directory in /data
and should be able to chmod and execute programs in it.

Hi @bgilbert - really great news, using the executable filters works well!

I've created an Android application and placed an executable filter in the
resource directory. At runtime, the filter is copied to the /data directory,
which allows the execute bit to be set.

I can use Java's runtime to spawn a subprocess and
read the InputStream. The following screenshot shows
the output bar, which is the string I added to the main method
to see if the program is actually executing.
