I use rubicon-java can't access android classes,such as "machine_build = JavaClass('android.os.Build')"

We're going to need a little more detail here, because I can point at extensive examples of Android classes being accessed successfully.

You might want to start with describing the error you've seen, and how you went about generating that error.

We're going to need a little more detail here, because I can point at extensive examples of Android classes being accessed successfully.

You might want to start with describing the error you've seen, and how you went about generating that error.

my python file 'main.py':
import time
from rubicon.java import JavaClass
def get_machineinfo():
machine_build = JavaClass("android.os.Build")
info1 = machine_build.BOARD
print(info1)
get_machineinfo()
while 1:
print("hello beeware!")
time.sleep(3)
but it has an error:

We're going to need a little more detail here, because I can point at extensive examples of Android classes being accessed successfully.

You might want to start with describing the error you've seen, and how you went about generating that error.

Thank you for your help!

Ok - so the problem will be that you're using the wrong format in your class reference. The error log you've posted tells you exactly what has gone wrong:

A/art: art/runtime/java_vm_ext.cc:410] JNI DETECTED ERROR IN APPLICATION: illegal class name 'android.os.Build'
art/runtime/java_vm_ext.cc:410] (should be of the form 'package/Class', [Lpackage/Class;' or '[[B')
art/runtime/java_vm_ext.cc:410] in call to FindClass

Rubicon-java uses JNI-style class name references - so you need to reference JavaClass('android/os/Build'), not JavaClass('android.os.Build').

Closing this ticket since it should now be resolved; if you have any further problems, feel free to continue the discussion here, or open a new ticket.
