App42 - Proguard setting necessary (because debug mode works and release mode fails)

Question

I create a query to check, if there exists new data. I compile my app in debug mode, run it and everything works fine. If I compile it in release mode, I get a NullPointerException...

Can this be related to proguard? Actually, I didn't find any proguard settings for App42...

I use version 3.0.1...

Storage storage =  storageService.findDocumentsByQueryWithPaging(db, collection, query, 1, 0);
storage.getRecordCount(); // <= this is NULL!!! But only in RELEASE build

Answer 1

Following proguard setting seems to work:

-keep class com.shephertz.** {*;}

There may be a better solution, but I could not find any documentation...
