I've hit the same issues few days ago, but reported it in the wrong project: kivy/pyjnius#83

gordianknotC · 2014-05-14T08:23:31Z

following coded crashed too

class Test (PythonJavaClass):
    __javacontext__ = 'app'
    __javainterfaces__ = ['android/view/View$OnDragListener']

    def __init__ (self):
        super (Test, self).__init__ ()

# reference overflow
for i in range(256):
    test = Test()

# reference overflow
for i in range(256):
    test = Test()
    del test

seems any interface implementation instantiated more than 25X times at once would cause reference overflow!

marccardinal · 2015-01-06T11:58:47Z

This kivy code also produces the JNI ERROR (app bug): local reference table overflow (max=512) error:

class MyApp(App):
    tickCount = 0

    def build(self):
        Clock.schedule_interval(self.Tick, 1)

    def Tick(self):
        self.GetMyLocation()

    @run_on_ui_thread
    def GetMyLocation(self):
        self.tickCount += 1
        print "Tick: %s" % self.tickCount

Which gives me the error:

In my use case I have a google map widget in the ui thread and a timer to periodically poll the user location. Is there a work around?

marccardinal · 2015-01-08T00:13:22Z

Has someone found a workaround? Some calls need to be made in the ui thread and running a function decorated with @run_in_ui_thread leaks very quickly.

oukiar · 2019-05-31T05:18:25Z

This is a workaround solution for this problem.

I found that every call to any function decorated with @run_in_ui_thread creates a new entry in the table of jni references, even if the call is for the same function multiple times.

The solution is keep a dictionary with all the functions called, and reused instead of create a Runnable in every @run_in_ui_thread call.

I think this solution is only usefull for call a limited number of different functions, maximum 490 functions approximately.

The changes must be made to the file:
python-for-android/pythonforandroid/recipes/android/src/android/runnable.py

And the complete new changes are:

from android.config import JAVA_NAMESPACE

# reference to the activity
_PythonActivity = autoclass(JAVA_NAMESPACE + '.PythonActivity')

#cache of functions table
__functionstable__ = {}

class Runnable(PythonJavaClass):
    '''Wrapper around Java Runnable class. This class can be used to schedule a
    call of a Python function into the PythonActivity thread.
    '''

    __javainterfaces__ = ['java/lang/Runnable']
    __runnables__ = []

    def __init__(self, func):
        super(Runnable, self).__init__()
        self.func = func

    def __call__(self, *args, **kwargs):
        self.args = args
        self.kwargs = kwargs
        Runnable.__runnables__.append(self)
        
        _PythonActivity.mActivity.runOnUiThread(self)

    @java_method('()V')
    def run(self):
        try:
            self.func(*self.args, **self.kwargs)
        except:  # noqa E722
            import traceback
            traceback.print_exc()

        Runnable.__runnables__.remove(self)
        
        


def run_on_ui_thread(f):
    '''Decorator to create automatically a :class:`Runnable` object with the
    function. The function will be delayed and call into the Activity thread.
    '''
    
    if f not in __functionstable__:
        
        rfunction = Runnable(f) #store the runnable function
        
        __functionstable__[f] = {"rfunction":rfunction}
        
    rfunction = __functionstable__[f]["rfunction"]
    
    def f2(*args, **kwargs):
