setAccessible() of java/lang/reflect/Field

[oastashev]

Hi there :)

I'm trying implement feature 'enable mobile data' by translating from java code to further python code:

Context = autoclass('android.content.Context')
Class = autoclass('java.lang.Class')
PythonActivity = autoclass('org.renpy.android.PythonActivity')

conman = PythonActivity.getSystemService(Context.CONNECTIVITY_SERVICE)
conmanClass = Class.forName(conman.getClass().getName())
connectivityManagerField = conmanClass.getDeclaredField("mService")
print connectivityManagerField
connectivityManagerField.setAccessible(True)

connectivityManager = connectivityManagerField.get(conman)
connectivityManagerClass = Class.forName(connectivityManager.getClass().getName())

setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", autoclass('java.lang.Boolean').TYPE)
setMobileDataEnabledMethod.setAccessible(True)
setMobileDataEnabledMethod.invoke(connectivityManager, True)

Executing under Kivy Framework I'v got exception:

I/python  (13732): <Field at 0x61ae9090 jclass=java/lang/reflect/Field jself=<LocalRef obj=0x1f300ce2 at 0x608b4940>>

I/python  (13732):      connectivityManagerField.setAccessible(True)
I/python  (13732):  AttributeError: 'Field' object has no attribute 'setAccessible'

Any ideas how to solve problem?

Is this a real issue? What is the problem?

Original java code:

final ConnectivityManager conman = (ConnectivityManager)  context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field connectivityManagerField = conmanClass.getDeclaredField("mService");
connectivityManagerField.setAccessible(true);
final Object connectivityManager = connectivityManagerField.get(conman);
final Class connectivityManagerClass =  Class.forName(connectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = connectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);

setMobileDataEnabledMethod.invoke(connectivityManager, enabled);

@oastashev @inclement Also I'm interested to enable mobile data in Android. How did it go then? Someone has managed to successfully implement the command? I could help if needed to implement the functionality.
