Android release minifyEnabled with couchbase - not working

Mobile
1

Hi,

I am using couchbase lite in my android application, and i have tried to compile it for release, using build signed APK.

My gradle has minifyEnabled=true for release target, and when i try to run it fails to create the manager with the following exception.
Proguard complains about it as well, and i did -dontwarn on couchbase package.
Running with minifyEnabled=false works, but i do want my code to be minified.

Thanks a lot in advance.
Adi

Hi @adic, can you try keeping the couchbase classes, not suppressing the warning from proguard. We use the proguard minification with couchbase successfully.

Also, which version of couchbase lite are you using? I thing they changed the package of jackson in one of the last releases, @hideki can confirm on that

-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.map.ext.**

-keep class com.couchbase.touchdb.TDCollateJSON { *; }
-keep class com.couchbase.lite.**{ *; }

Regards,
Vlad

Hi @vladoatanasov, Couchbase Lite v1.1.0 depends on Jackson v2.5.0.
