Application can not be signed while using SQLCipher

[KinjalDroid]

I am using SQLCipher library to encrypt database in Android.
It works perfectly fine and database is also get encrypted.
But I am using Proguard for better security..so when i am going to sign app, Proguard gives me error like "Proguard returned with error code 1.See console"

And in console, it shows too many warning..

Warning: com.google.common.base.Equivalence: can't find referenced class javax.annotation.Nullable
Warning: com.google.common.base.Objects$ToStringHelper: can't find referenced class javax.annotation.Nullable
Warning: com.google.common.base.Predicates$AndPredicate: can't find referenced class javax.annotation.Nullable
Warning: there were 607 unresolved references to classes or interfaces.
You may need to specify additional library jars (using '-libraryjars').
java.io.IOException: Please correct the above warnings first.

If anyone know,please correct me.
Thanks..

Hello KinjalDroid,

Please try the following ProGuard file as a reference for use with SQLCipher for Android.

It disabled obfuscation/shrinking for sqlcipher :(.
Why exactly sqlcipher cannot be obfuscated? Does it use such a dynamic class/method loading?

Hello @fikr4n

We provide a sample reference, however you may be able to make adjustments to the ProGuard that still allows for proper execution. Have you run into a problem removing the -dontobfuscate flag? You will likely need to include something such as native <methods>; within a keep clause.

I mean it works, but disabling the obfuscation. So the point is my question:

Why exactly sqlcipher cannot be obfuscated? Does it use such a dynamic class/method loading?

Thank you for fast reply 👍

Hi @fikr4n

I mean it works, but disabling the obfuscation.

Did you try removing the -dontobfuscate flag and adding the native <methods>; within a keep clause? We do not provide ProGuard solutions for all configurations, the included configuration is just a sample.

Of course -dontobfuscate is removed, the main code would be obfuscated, but sqlcipher would not.
