Describe the bug
The Empty test app crashes at startup in Android with «Didn't find class "tech.kinc.KincActivity" on path: DexPathList» (without changing the package name of the app).

To Reproduce
Steps to reproduce the behavior:

  1. Compile Empty test app to Android using kmake android, them build with Android Studio.

Execution Environment:

  • Host system (where you compile your code): Linux Mint
  • Target system (where you run your code): Android Emulator with Pixel 3a API 34.
  • IDE and/or compiler used: Android Studio.
  • Kinc revision: f7d6ef53
  • Kinc build output: Using Kinc (f7d6ef53)
  • Application output (if it runs):

LogCat message:

Maybe there is something missing in my system?

Hu, f7d6ef53 does not seem to be an actual Kinc revision. Also your build output is incomplete.

Ups! Sorry, I was compiling from the wrong directory, so it looks like kmake wasn't picking the right folder for Kinc.

Now, compiling from the right directory (I've also tested from another directory but using the -k option to specify my global Kinc folder, with same results):

Looks like something related to Vulkan — if I compile with --graphics opengl the example works as expected (shows a red triangle).

Well, that wasn't the same result at all, that was a completely different crash. Will have a look at the Vulkan situation.

Ah, "same result" was just related to the -k option. Alright.

It looks like an incorrect double usage of a va_list argument in kinc_log when targeting Android, I'll do some tests and a pull request with a fix.
