while this worked in 1.2.1.

Can you show a simpler test case, and then we make a new issue?

With 1.2.1:

>>> from jnius import autoclass
>>> s = autoclass("java.lang.String")
>>> s.toString()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "jnius/jnius_export_class.pxi", line 755, in jnius.JavaMethod.__call__
  File "jnius/jnius_export_class.pxi", line 699, in jnius.JavaMethod.ensure_method
jnius.JavaException: Unable to find a None method!
classname: None, definition: ()Ljava/lang/String;
>>> s("foo").toString()
'foo'
>>> s.toString()
'foo'

With 1.3.0:

>>> from jnius import autoclass
>>> s = autoclass("java.lang.String")
>>> s("foo").toString()
'foo'
>>> s.toString()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "jnius/jnius_export_class.pxi", line 1134, in jnius.JavaMultipleMethod.__call__
jnius.JavaException: No methods matching your arguments, requested: (), available: []

Since calling a non-static method on a class no longer works, the problem’s already been fixed. And now we understand the cause of the problem. So I don’t think we need a new issue.

So the summary for anyone reading this in the future:

the bug was with python-for-android, and the patch has been merged: https://github.com/kivy/python-for-android/pull/2341
Pyjnius now has an improved error https://github.com/kivy/pyjnius/pull/558

hi guys I have the same problem, how to solve it? it’s possible to use an older pyjnius in buildozer build? thanks!

Pinning the version using requirements = pyjnius==1.2.1,... should work.
