Tango & Proguard

[jazzyjester]

Hey ,

Does anybody succeeded to sign tango libs with proguard ?

I'm trying to sign it using eclipse, and receive many errors...

I found the solution,
Need to add to the project the tango-cloud-lib.jar library from Here

or Here with more updated library

And after that, need to ignore the tango classes :

-keep class com.google.atap.** { ; }
-keep interface com.google.atap.* { *; }

This worked for me.

As a suggestion, since .AARs now support the addition of custom Proguard rules, this could be added to the SDK.

Proguard support is important when you need to include more libraries in a project, since these days just adding Google SDKs to a project brings you close to the 64k method limit, and a lot of developers will solve that by minifying their builds.
