re-sign.jar has outdated hardcoded path for zipalign #694
Description
I have been trying to find current documentation on how to use Robotium for APK files (without using Robotium Recorder) and rediscovered the relevant wiki page exported from Google Code. Even though the documentation is dated I thought I'd try following it. The re-sign process fails as it looks for zipalign in the tools folder of the Android SDK. However, this program was moved several releases ago to a versioned folder in build-tools.
BTW: the issue was also reported on SO http://stackoverflow.com/questions/24672479/not-able-to-unsign-apk-file-using-re-sign-jar by someone else a while back.
Please could you modify re-sign.jar so it uses the path to find zipalign. Also, updated examples for using Robotium standalone to test APK files would be very helpful.
