Android-release build (proguard rules)

[antailyaqwer]

Maybe this must be somewhere in the readme file

To run android build with minification enabled we shoud add some rules to proguard-rules.pro file:

-keep class com.ionspin.kotlin.crypto.** { *; }
-keep class com.sun.jna.** { *; }

I'm getting this when I try these proguard rules. Did you run into anything like this?

ERROR: Missing classes detected while running R8. Please add the missing classes or apply additional keep rules that are generated in /Users/edenman/workspace/x-android/app/build/outputs/mapping/release/missing_rules.txt.

Are you using multiplatform compose?

[edenman]

nope, just KMP

[ionspin]

Ah, I didn't see it was from JNA. I guess you could add dontWarn for those classes -dontwarn java.awt.HeadlessException

[ionspin]

Here's the source of JNA Native.java with those classes if you are interested in why they pop up https://github.com/java-native-access/jna/blob/master/src/com/sun/jna/Native.java

Nice. That works! full set of proguard rules:

-keep class com.ionspin.kotlin.crypto.** { *; }
-keep class com.sun.jna.** { *; }
-dontwarn java.awt.**
