When I tried to use troido.de’s APK re-signer, I encountered problems with the on PC and MAC with the
ANDROID_HOME variables not being set. Via StackOverflow and general poking around, I eventually got the re-signer to work:
add the following to your .bash_profile
In System Properties > Advanced > Environment Variables set two system variables (depending on your install locations);
Note: in the case of the re-signer tool, if double clicking on the jar doesn’t work (you are still asked to set the
JAVA_HOME variable), try running from your command line;
java -jar re-signer.jar.
