Instruction for upgrading the Onegini Android SDK to version 9.1

When upgrading to version 9.1 some changes have to be applied in the end application:

Minimum supported Token Server Version 8.2.0

Due to the SDK initialization improvement you need to update the Token Server to at least 8.2.0 version first.

New application signature algorithm

The application signature (secret) is now calculated using new algorithm that takes Google Play Store metadata into account. This algorithm is different than the one used by the Application Signature Calculator v1.x. Therefore, if you want to use the Application Signature Calculator you must use the updated v2.x

Onegini SDK ProGuard rules were embedded into the library

The proguard-onegini.pro file has been embedded in the Onegini SDK library and it no longer has to be explicitly specified in your application. You can remove the proguard-onegini.pro file from the application and edit your proguardFiles configuration in the buildTypes section of the application's build.gradle file to remove its usage.
