Question:

Android studio reports an error: module was compiled with an incompatible version of kotlin. The binary version of its metadata is 1.5.1, expected version is 1.1.15.
Solution 1:

Add ext.kotlin in build.gradle of the project_ Version = "1.3.72" (lower version) changed to ext.kotlin_ Version = "1.5.21" (not necessarily 1.5.21, but also the latest version). Just sync and run again

Solution 2:

Open build.gradle under your module (my module name here is MyLibrary) directory, delete some lines in dependencies, and only the corresponding lines in the second figure are left. Just run it again

these lines remain:
