I can't remember if it was Compose or Flutter, where I spent a ridiculous amount of time trying to get something to stay centered on the screen regardless of orientation. Something that I could do pretty easily and quickly with my own UI tech library in C++. However I can't use that code without having to jump through all the annoying hoops you have to jump through with JNI crap in order to use it. So I just don't bother with Android anymore.
