GeneratedLexer.kt has conflicts with Java functions in Android 15 #197
Description
After updating to use newer R8 functionality in my app I got the following error on my first upload of a new AAB file to Google Play.
Kotlin incompatibilities will cause crashes
Your app uses Kotlin's removeFirst() and removeLast() extension functions, which conflict with Java functions in Android 15. This will cause apps to crash on devices on Android 14 or earlier. Your app uses these functions in the following places:
org.intellij.markdown.lexer.GeneratedLexerKt.pop
To avoid crashes, replace all Kotlin removeFirst() and removeLast() function calls with removeAt(0) and removeAt(list.lastIndex).
Looking at the source code, it does seem that the file and function in question exist in the codebase and could cause an issue if a user used the library in question to trigger that specific markdown lexer and called the .pop() function on an Android 14 or lower device.
It seems it might be possible to instead have the library call the following so that it works on Android builds as well as other implementations:
fun <E> ArrayList<E>.pop(): E = removeAt(lastIndex)
Activity

Seeing this too. Confirmed via APK decompile that this is the only offending call site in our build — R8 retrace mis-attributes it to an unrelated Activity, but the actual bytecode is
ArrayList.removeLast()fromGeneratedLexerKt.pop, which NoSuchMethodError-crashes on Android 14 and below.Also worth flagging: it's still present on the latest 0.7.7 — the
pop() = removeLast()line is unchanged.+1 for the
removeAt(lastIndex)fix; would be great to get a patch release out.p3rmiashkin commentedon Jul 28, 2026
The fix for the problem will be delivered in 0.7.9

Hi Ilia Permiashkin (@p3rmiashkin), just curious if there's an ETA on 0.7.9 shipping? We're seeing these warnings in the Play Console and would love to be able to get them cleared up 😄. Thanks!

Thanks!
Update jetbrains markdown for blocking release issue.
