Regarding the issue of errors when importing Java APIs due to differences in syntax between Java and Python

This webpage introduces Build, which is at the same level as Build in android.os Partition
If imported according to the same syntax, it would be:
from android.os import Build.Partition
But if imported in this way, it will cause Python syntax errors:
E/AndroidRuntime: java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.adm/org.beeware.android.MainActivity}: com.chaquo.python.PyException: SyntaxError: invalid syntax (app.py, line 1)

This is covered in the Chaquopy documentation:

Nested and inner classes cannot be imported directly. Instead, import the outer class, and access the nested class as an attribute, e.g. Outer.Nested.

In this case that would be:

from android.os import Build
Build.Partition
