Please try below commands after you meet the issue:

ls -l /tmp/libs
adb logcat -d

And then log the output in the issue. Many thanks.

Hi xiaocong:
I've solved the problem by upgrade the uiautomator to version 0.1.18. And I'v made some tests.
It is really easy and convenience to use.
And I have a suggestion.
You may compact a few commands into a package insead of each command s rpc call.
And your application could not run on Android(4.1, 4.2). Because each version of android has its own uiautomator.jar

In  README.md: from uiautomator import Device will raise en error. Device is missing.
 dir(uiautomator)

['JsonRPCClient', 'Selector', '_Adb', '_AutomatorDevice', '_AutomatorDeviceObject', '_AutomatorServer', '_JsonRPCClient', '_Selector', 'all', 'author', 'builtins', 'doc', 'file', 'name', 'package', 'version', 'adb', 'device', 'hashlib', 'itertools', 'json', 'os', 'param_to_property', 'point', 'rect', 'server_port', 'subprocess', 'tempfile', 'time', 'urllib2']

In total, thanks your idea and your sharing.

from uiautomator.

Thanks a lot.

For your first suggestion, can I know the exact usage scenario for compacting a few commands? It's very important for me to understand for what exact reason the requirements are raised.

You mentioned something wrong on Android 4.1/4.2, could you please give me some clues for it? I could not reproduce it on my Android4.1/4.2 devices. I really appreciate if you can put some logs on the issue.

And for the last issue, likely you import a wrong uiautomator package, please check all files in the directory you run the script.

do you know why this happened? thanks.

from uiautomator.

Likely bundle.jar file missed. Please help check if there is the file under /data/local/tmp. Thanks.

hi @xiaocong
Recently, I'm trying to use your wrapper on android L, but some problems occur, would you please tell me the version number of nanohttpd release that you've packaged into your bundle.jar? thanks!

from uiautomator.

Thank you. I just add a fix for the issue. Please help check whether the fix works.

from uiautomator.

it works fine, thanks you.

from uiautomator.

it seems like it's the storage problem which cause this.
