Getting NoClassDefFoundError while trying to use Proguard and SQLcipher in Android

Question

I am getting a ava.lang.NoClassDefFoundError: net/sqlcipher/CursorWindow when trying to run my app using sqlicipher and proguard. The project works perfectly without proguard enabled. The first time I use sqlcipher to create a new db I get the error above. I have looked at another SO question that is seemingly identical, but I have tried the answers from that question and I'm still getting the error.

I think that the class was removed by the Proguard Shrinking tool.

Try to add the following parameter

-dontshrink

and tell me if it works.

I also saw that an attribute is missing in a protected class of Sqlcipher :

: E/AndroidRuntime(18993): Caused by: java.lang.NoSuchFieldError: no field with name='nHandle' signature='I' in class Lnet/sqlcipher/database/SQLiteCompiledSql;

Can you also try to keep protected classes from Sqlcipher ?

-keep class net.sqlcipher.** {
    *;
}

P.S Is it regular that you have the option -dontobfuscate in your configuration ? Your application will not be obfuscated if you keep it.

After having this precise problem, `-keep class net.sqlcipher.** {*;}` (so "public" was removed), worked for me. – Chris Horner Jan 30 '14 at 00:52
Hmm... it disables obfuscation for sqlcipher. Actually, is dynamic class/method loading (reflection) the only reason that ProGuard breaks your app? – fikr4n Feb 05 '16 at 14:57
@ChrisHorner the solution works but increases size of apk by half see here https://stackoverflow.com/questions/54289061/sqlcipher-and-cwac-saferoom-doubling-the-size-of-my-apk?noredirect=1#comment95400717_54289061 – Geek Guy Jan 21 '19 at 15:11

Try this:

-keep class net.sqlcipher.** { *; }

In the Java build path, Order and Export, check the library so that it will be exported.

Remove public from the below statements. Worked for me. :)

-keep class net.sqlcipher.** {
    *;
}

-keep class net.sqlcipher.database.** {
    *;
}
