问题
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.

回答1:
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.
回答2:
Try this:
-keep class net.sqlcipher.** { *; }
回答3:
In the Java build path, Order and Export, check the library so that it will be exported.
回答4:
Remove public from the below statements. Worked for me. :)
-keep class net.sqlcipher.** {
*;
}
-keep class net.sqlcipher.database.** {
*;
}
