Android Resign

This script allows you to resign any APK with any certificate.

Prerequisites

You'll only need the APK you want to sign and the Keystore with all it's informations.

Disclamer

The script was only used and tested on a Mac OS Environment. It should work fine on any Unix distribution though. Only native APKs were re-signed with this script, never tried anything else.

How to

1. Clone this project.
2. Create a file "whatever.properties" containing the following

storeFile=/Path/To/keystore.jks
keyAlias=your_key_alias
keyAliasPassword=your_key_password
storePassword=your_store_password

3. Execute the Script with the following command line

./signapk.sh my_apk.apk whatever.properties
