I am taking over an Android application that was originally signed with both a private keystore and the Titanium dev_keystore that ships with the SDK. The app was published to the Play Store being double-signed this way and the device will throw a signature error if the APK is not signed with both keys.
Does Titanium offer a free, perpetual license to use the keystore for signing of future applications which were originally developed with Titanium, but are later rewritten natively?
The alternative is to unpublish the old app and force new users to uninstall/install a different app assuming they respond to an email campaign.
