Empty json data in Release build (using proguard)
I guess that it is caused by proguard. Proguard is probably obfuscating some portion of your code, but this code is dynamically invoked by Spring (and jackson ? you didn't mention it). (and so once it is obfuscate : dynamic invocation failed)
So try to :
- disable proguard to confirm that it is the cause of the problem
if it is confirmed : try to configure it so hat it won't obfuscate class that are serialized in json (i.e. UserMessage) :
-keep class com.company.UserMessage** { *; }
I have same issue, and I committed below 2 line
// shrinkResources true
// minifyEnabled true
The above answer didnt work for me may be it was correct on 2014For 2019 when I set the compileSdkVersion 28 it works.
