App Crashing With Proguard Enabled

My app runs perfectly without proguard enabled but when I enable it the app crashes right away. I have tried many combinations in the configuration to no avail. Is there something

Solution 1:

I found the offending code. I changed my Proguard.cfg to match the following:

https://github.com/google/gson/blob/9f8ace9ac4c56b82eba1bbd8b44f80e042bda7e0/examples/android-proguard-example/proguard.cfg

And now everything is working!

Solution 2:

Usually proguard removes few classes if they are not explicitly set as

-keepclassmembers ....

But such errors are shown as classNotFound, NoSuchMethodException etc..,

Anyways decode the log cat you got using this and check what actually caused the NPE.
