HI:
I use Unity 2021.3.27f1 version, everytime when building android apk unity editor crash. If I delete all Library directory to reimport all assets , build maybe will success once or twice. My two computer have same problem.
My window system version is Windows11. 22621.1848. I can not use crash report successfully, will tip " can not write"… please check the attachment files.
First, make a blank project with a single blank scene and prove that it builds successfully.
If the blank project does NOT build, go fix your Unity installation or your other tools, such as Android SDK, NDK, JDK, etc. It may even be necessary to change to a different version of Unity3D. It is generally best to stay with LTS versions of Unity3D.
Until you can build a blank project to the target platform, don’t fiddle with anything else.
Once you can build a blank project, now bisect the problem by bringing over parts of your current project and building it one subsystem at a time, perhaps stubbing things out that might trigger compiler errors.
Most often things that prevent building are third-party libraries such as Firebase.
Once you identify the subsystem, go to the documentation for it and make sure you are doing it correctly.
It may also be helpful to work through a tutorial or two for whatever subsystem is making the build fail.
Android build not building:
Recently (circa July 2022) there have been reports of Unity’s installer failing to install the Android Tools.
Here was how I brought up Unity2020.3.41 and the Android SDK 31 on October 30, 2022:
Thank you so much. I created a new empty scene under the current project, so there was no problem in building Android, no Crash, no Error. Prior to this, I spent over a week deleting my 3rd plugins one by one, but still the editor crashed. Thank you very much again!
