I have the following in my proguard.cfg file and I absolutely cannot run my obfuscated APK file to save my life

-keep class info.guardianproject.database.** {*;}
-keep class info.guardianproject.database.sqlcipher.** {*;}

-libraryjars /libs/commons-codec.jar
-libraryjars /libs/guava-r09.jar
-libraryjars /libs/sqlcipher.jar
-libraryjars /assets/icudt46l.zip

What is the "secret" to being able to configure a proguard.cfg file for SQLCipher use??

Thanks,
Emery

Try adding "-dontskipnonpubliclibraryclasses" to proguard.cfg.


Thanks,

I already had that in proguard.cfg and it still isn't working....  

Here is my entire proguard.cfg:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-ignorewarnings 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keep class info.guardianproject.database.** {*;}
-keep class info.guardianproject.database.sqlcipher.** {*;}

-libraryjars /libs/commons-codec.jar
-libraryjars /libs/guava-r09.jar
-libraryjars /libs/sqlcipher.jar
-libraryjars /assets/icudt46l.zip
     
-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}

Hi Emery,

I don't know anything about ProGuard configs, but the namespace was changed from info.guardianproject.database to net.sqlcipher.database, perhaps that will help?

Billy Gray

Hi Billy,

I've tried changing the references accordingly.  No matter what I do, at run-time I get:

07-02 06:51:47.497: W/dalvikvm(6633): VFY: 'this' arg 'Ljava/lang/Object;' not instance of 'Lnet/sqlcipher/database/SQLiteProgram;'
07-02 06:51:47.497: W/dalvikvm(6633): VFY:  rejecting opcode 0x6e at 0x013d
07-02 06:51:47.501: W/dalvikvm(6633): VFY:  rejected Lnet/sqlcipher/database/SQLiteDatabase;.insertWithOnConflict (Ljava/lang/String;Ljava/lang/String;Landroid/content/ContentValues;I)J
07-02 06:51:47.501: W/dalvikvm(6633): Verifier rejected class Lnet/sqlcipher/database/SQLiteDatabase;
07-02 06:51:47.548: D/AndroidRuntime(6633): Shutting down VM
07-02 06:51:47.548: W/dalvikvm(6633): threadid=1: thread exiting with uncaught exception (group=0x4001d7f0)
07-02 06:51:47.551: I/dalvikvm(6633): Rejecting re-init on previously-failed class Lnet/sqlcipher/database/SQLiteDatabase; v=0x48309b38
07-02 06:51:50.713: I/dalvikvm(6633): Debugger is active

It appears that the obfuscator caused SOMETHING to no longer be recognizable as being a net.sqlcipher.database.SQLiteProgram despite it being so.  I can't figure out what it is that isn't being recognized....

I appreciate the help.  Any other ideas?

Thanks,
Emery

Hi Emery,

Can you share your updated configuration file?  Do you have the following included:

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

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

Hi Nick,

I *JUST* made the changes that you suggested; didn't seem to make any difference...  The updated proguard.cfg is:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose
-ignorewarnings 
-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

-keep public class * extends android.app.Activity
-keep public class * extends android.app.Application
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-keep public class net.sqlcipher.** {*;}
-keep public class net.sqlcipher.database.** {*;}

-libraryjars /libs/commons-codec.jar
-libraryjars /libs/guava-r09.jar
-libraryjars /libs/sqlcipher.jar
-libraryjars /libs/jsr305-1.3.9.jar
-libraryjars /assets/icudt46l.zip
     
-keepclasseswithmembernames class * {
    native <methods>;
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet);
}

-keepclasseswithmembers class * {
    public <init>(android.content.Context, android.util.AttributeSet, int);
}

-keepclassmembers class * extends android.app.Activity {
   public void *(android.view.View);
}

-keepclassmembers enum * {
    public static **[] values();
    public static ** valueOf(java.lang.String);
}

-keep class * implements android.os.Parcelable {
  public static final android.os.Parcelable$Creator *;
}

Hi Emery,

I've recreated your issue with the supplied configuration, could you try making this small adjustment.  You currently have:

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*

could you try swapping this in instead:

-optimizations !code/simplification/arithmetic,!field/*,!class/merging/*,!code/allocation/variable

Hi Nick,

Please see the private email I sent to you.  We're making progress, but we're still not out of the woods.

Best Regards,

Ok.  Nick asked me to try "dontskipnonpubliclibraryclassmembers" in addition to everything else I've tried.  Didn't make any difference.

What should I try next??

Thanks,
Emery

Hi Emery,

I've put together a sample proguard.cfg configuration file that works properly with SQLCipher for Android.  Could you try this and let us know how it works out:

Good news - that worked (with some modifications ).

I needed to add:

-libraryjars libs/jsr305-1.3.9.jar
-ignorewarnings 
-keep public class * extends android.app.Service
-keep public class * extends android.content.BroadcastReceiver
-keep public class * extends android.content.ContentProvider
-keep public class * extends android.app.backup.BackupAgentHelper
-keep public class * extends android.preference.Preference
-keep public class com.android.vending.licensing.ILicensingService
-dontwarn javax.naming.**
-assumenosideeffects class android.util.Log {
    public static *** d(...);
    public static *** v(...);
}

Bad news - when I commented out -dontobfuscate it fails again and the whole point of using ProGuard is to obfuscate the code.

I get what's below - it seems to be failing on an attempt to get to a field in net.sqlcipher.database.SQLiteCompiledSql  Not sure what to do with it...

Thanks,
Emery

Bad news - when I commended

Update - I changed it to what's below and also got rid of "-dontobfuscate" and it's still working.

Does this make sense?  Can someone  that really understands ProGuard explain why this works and with the "public" it doesn't??

Thanks,
Emery

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

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

I also noticed that there is an unnecessary redundancy (as if there ever is a necessary redundancy?)

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

The use of **, if I understand the documentation correctly, means that the following is not necessary.  I've tried removing it and it doesn't seem to make a difference....

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

Hi Emery,

I'm glad to hear you were able to get ProGuard working with SQLCipher for Android.  Based on the -keep documentation [1] they recommend specifying all publically accessible elements.  The obfuscation should still occur with exception to those marked with the -keep option.  Thanks for getting back to us!

Hi Nick,

Thanks for all of your help in getting me here.  I doubt I could have gotten here without that help.

I had read that already and thought that further relaxing what ProGuard was doing with SQLCipher could be worth a try.

It sounds as if I am telling ProGuard to not obfuscate any of SQLCipher at all (both internal members and external members), but to obfuscate all of my code (with minor exceptions).  It seems as if some fields within SQLCipher are being accessed directly - I'm not sure what and I'm not sure what is making such access.

I have no idea if any of these insights are helpful to you in any way; I hope so.

Best regards,
Emery

Hi Emery,

There is a native JNI layer within SQLCipher for Android, various native functions are registered within the runtime when you invoke SQLiteDatabase.loadLibs.  During that registration, we verify that certain fields are accessible as they need access to them at a later period, so those fields can't be renamed by ProGuard.  Thanks for the feedback around the tweaks you did to your ProGuard configuration.

Nick,

Thanks for the explanation.  I've done some more work on simplifying. 

I've been able to get rid of:

-dontskipnonpubliclibraryclasses 
-dontskipnonpubliclibraryclassmembers 
all of the -libraryjars (it's sufficient to just have them in the list of libraries on the Java Build Path from the Project Properties)

Accordingly, I think that the instructions can be dramatically simplified.  All I really needed, I think, was:

-optimizations !code/simplification/arithmetic,!class/merging/*,!code/allocation/variable
-keep class net.sqlcipher.** {
*;
}

Hope this helps.

Emery
