GPS example crashes

[lipi]

Trying to run the following code (from the docs):

from time import sleep
from plyer import gps

def print_locations(**kwargs):
    print 'lat: {lat}, lon: {lon}'.format(**kwargs)

gps.configure(on_location=print_locations)
gps.start()
sleep(5)
gps.stop()

However it crashes:

Could you describe what you did in more detail? Running the code seems to work fine for me:

I/python  ( 5315): Starting audio thread

Did you run this on Android? That could be the problem, as I think that
there problems running this on Windows.

At this point the GPS facade is only available for Android. It will raise a NotImplemented Error on all other platforms.

[lipi]

It is running on Android, as you can see in the logcat output.

I used the latest (master) python-for-android, which in turn pulled the latest pyjnius I believe. Android version is 4.4.2.

What device and version of Android are you using?

Nexus 4 and Android 4.4.2 Python-for-andorid was built on Ubuntu 12.04, using NDK r9c and SDK 19.

Will try to reproduce it with different SDK level on different host and phone.

[trivedigaurav]

Although I have not yet been able to reproduce the issue, it seems to be a Pyjnius issue and not necessarily specific to the GPS example. It occurs when calling the constructor to the PythonJavaClass. Here is another such reported issue on 4.4.2: kivy/pyjnius#92

[lipi]

Thanks for the tip, the example works after switching the runtime back to Dalvik.

I am closing this issue as it seems to be a duplicate of kivy/pyjnius#92

I am having trouble running the gps example in plyer.. I runned it but it is stuck with getting Click start to get GPS location updates. I runned it in kivy luncher with plyer and buildozer inside. can u please provide a screeshot of what should be seen after running the application and provide a clear step by step of running properly this program. PLease..............

[brousch]

I don't think Kivy Launcher has the Android permissions necessary to use
the GPS. You should compile an APK using buildozer and install it to your
device. Putting buildozer in your project does nothing.

can i get an apk of the plyer example for gps? i will install it in my phone because I am really curious about this python program?

[iamryanmoreno]

why is that when i runned the other examples, its working in my kivy launcher only that of gps is not. can someone provide another library for accessing gps in kivy?

[moonpyx]

hello, glad , download the GPS example plyer https://github.com/kivy/plyer/tree/master/examples/gps but for android in buildozer compile the application does not start when installed on my device with android 4.4.4 Error throws me NotImplementedError. thanks
