5.19.0 silently bumps the minSdk version on Android to 26

[jmartinesp]

I was reviewing an automatically generated PR to bump the JNA version on our repo and I saw several CI issues, containing errors like:

ERROR: /home/runner/.gradle/caches/9.2.1/transforms/2800b81311717ffd6b204bc28609c907/transformed/jna-5.19.0-runtime.jar: D8: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26): Lcom/sun/jna/Native;->getWebStartLibraryPath(Ljava/lang/String;)Ljava/lang/String;

Or

Caused by: com.android.tools.r8.internal.g: MethodHandle.invoke and MethodHandle.invokeExact are only supported starting with Android O (--min-api 26): Lcom/sun/jna/Native$2;->apply(Ljava/util/stream/Stream;)Ljava/lang/Class;

Our app uses minSdk 24, so it was failing to build. I took a look at the latest changes in JNA since 5.18.1 and I couldn't find any that could explain it, since the mentioned code hasn't been changed in years in some cases. I've attached the whole error log:

minSdk26.txt

That would be most probably this:

#1638

@jmartinesp please have a look at #1731. Can you build from source and test that or do you need a prebuilt .aar?

[jmartinesp]

Oh, that was fast, thanks! If possible, an aar would be great.

@jmartinesp please use this build: https://central.sonatype.com/repository/maven-snapshots/net/java/dev/jna/jna/5.19.1-SNAPSHOT/jna-5.19.1-20260611.183553-1.aar

I just tested it and it seems to be working fine. Thanks again!

[matthiasblaesing]

@jmartinesp thanks for testing!
