ImportError android

[konbernu]

I m trying to import activity from android. Code:

from android import activity

I m using webview as bootstrap and the following recipes: flask,pyjnius,android. When I try to run the app, I get the following error:

I/python: [INFO ] [Logger ] Record log in /data/user/0/org.example.myapp/files/.kivy/logs/kivy_16-11-28_0.txt I/python: File "/data/user/0/org.example.myapp/files/environment.py", line 20, in <module> I/python: File "/data/user/0/org.example.myapp/files/lib/python2.7/site-packages/android/__init__.py", line 8, in <module> I/python: ImportError: dlopen failed: file offset for the library "/data/user/0/org.example.myapp/files/lib/python2.7/site-packages/android/_android.so" >= file size: 0 >= 0

No errors during compilation? Have you tried to unzip the apk and look if it's really present? Sometimes cleaning build/dists seems to be necessary.

the first time i compile there is an error:

the second time i try to compile, it compiles without an error, so there might be the problem at building android

I think this is currently working. The original error about size-zero files related to failing to load libpymodules.so, which was both fixed and is no longer an issue as we don't create that file any more.

Please make a new issue if you do experience the same issue again.
