Some URL fixes from @jduck and exploit ideas from Andre Moulu.

The exploit works with the URLs fixed, installs the APK, but hangs at the Installing...
screen and never actually launches. We tried opening the APK in a setTimeout() intent
URI, but the previously launched intent seemed unresponsive. Andre had the bright
idea of re-opening the previously launched intent with invalid args, crashing it and
allow us to launch the payload.
