(P.S. I am trying now to put these file changes to a branch so you can see better)

Thanks. Way easier for me :)

Abort message: 'JNI DETECTED ERROR IN APPLICATION: JNI CallBooleanMethod called with pending exception java.lang.NoSuchMethodError: no non-static method "Lorg/koreader/launcher/MainActivity;.hasStandaloneWarmth()Z"

What am I doing wrong?

Nothing wrong, my comment wasn't exhaustive. You'll need to add the method to https://github.com/koreader/android-luajit-launcher/blob/master/app/src/main/java/org/koreader/launcher/LuaInterface.kt and override it in https://github.com/koreader/android-luajit-launcher/blob/master/app/src/main/java/org/koreader/launcher/MainActivity.kt

It (mainactivity) will look like:

override fun hasStandaloneWarmth(): Boolean {
    return device.lights.hasStandaloneWarmth()
}

Thank you @pazos ! KOReader was able to open with these changes. I am able to turn off the frontlight (cold and warm) via a gesture.

However, when I turn it back on, only cold light turns on. I am trying to investigate this.

android-luajit side of things (this PR) is correct. The mentioned PR is in discussion.

@pazos Please review this PR. It should be generalized enough so that we don't need to add devices one by one to make these changes apply - as long as they properly refer to this OnyxWarmthController.

Thank you for all your help!

That's the entire point of the device abstraction ;)

PR is fine by me, please address specific comments.

Thank you! While adding my newlines, I noticed some methods didn't have them, so I added those newlines too, for consistency.
