So, what is the proper way of building apps for 64-bit Android in Unity? I'm using IL2CC scripting backend and checking the x64 checkbox. Then in build settings, I checked Android App Bundle. The .aab builds fine but the game crashes while logging into Google play services. It works perfectly however if I use Mono scripting backend(default) and just build an apk. In summation - .apk always works perfectly with or without google play services .aab works perfectly without, but crashes on login if using google play services I also tried using logcat and it's not very helpful, or at least I can't read and interpret anything from it. The only thing different between the two is that the log from when it doesn't crash has a bunch of extra lines at the end of it. Here are the two files : When it crashed : https://pastebin.com/zeB4Tt7Y When it didn't crash : https://pastebin.com/gW2yfNs4 Been frustrated by it for 3 days now, any help would be greatly appreciated. Thanks!
