Instruct ProGuard to Not Remove Anything From My Package

Is it possible to set ProGuard to not remove anything from my package? The App size savings are minimal and it breaks my application all together.

Certainly, you can use a broad -keep rule to achieve it like this:
-keep class com.example.package.** { *; }

In case you still want to obfuscate the code that’s part of this package and underlying packages you can use a keep option modifier like this:
-keep,allowobfuscation class com.exmple.package.** { *; }

Alternatively, if you want to get the most out of ProGuard, you can try narrowing down this broad -keep rule so that it will only preserve the necessary classes, methods, etc. to prevent your app from crashing.
