They compile Java Bytecode to Dalvik Bytecode and run that on the Android Runtime which is a tiered JIT compiler.

It still inherits the issues of Java such as the GC, no stack allocated value types, poor cache locality, etc. Although tbf the GC on Android is pretty fucking good these days and doesn't pause the world anymore.
