httplib.BadStatusLine: '' on Android L with uiautomator 1.4

[mayujsw]

we met badstatusline error when trying uiautomator 1.4:

per the UIautomatior v1.4 steps: Run the jsonrcp server on Android device

$ adb shell uiautomator runtest  uiautomator-stub.jar bundle.jar -c com.github.uiautomatorstub.Stub
$ adb forward tcp:9008 tcp:9008 # tcp forward

How to use

Next is a python example using jsonrpclib. Before you run it, make sure install jsonrpclib via pip install jsonrpclib.

import jsonrpclib
server = jsonrpclib.Server('http://localhost:9008/jsonrpc/0')

server.wakeUp()
server.pressKey("home")
server.pressKey("back")

we met error on step "sever.wakeup()" as below:

BTW, sdcard is inserted during these steps, as i saw this error may be related to sd-card as recorded in other threads.....

Could you please run below command?

$ curl -d '{"jsonrpc":"2.0","method":"ping","id":"1234"}' -H 'Content-type: application/json' http://localhost:9008/jsonrpc/0

If the output is {"jsonrpc":"2.0","id":"1234","result":"pong"}, the server is ok, else the server is not up.

[mayujsw]

hi xiaocong,

Thanks much for your quick reply, but we still met error as below for your command: HOST$curl -d '{"jsonrpc":"2.0","method":"ping","id":"1234"}' -H 'Content-type: application/json' http://localhost:9008/jsonrpc/0 curl: (52) Empty reply from server

[mayujsw]

we tried on Nexus7 with android L, not sure whether anyone make it workable now ...

[xiaocong]

I can reproduce it. Likely NanoHttpd failed to open temp file. I am looking at it. Thank you.

[mayujsw]

Great to know, thanks :)

[xiaocong]

Please update to v0.1.32 and check if it's fixed. Thx

[mayujsw]

Thanks for your quick update, we'll give a try tomorrow morning :)

[mayujsw]

It's OK now, thanks xiaocong !

[mayujsw]

after we do adb reboot, it can not work anymore, reporting "Connection reset by peer" as below

[xiaocong]

Could you please capture device logcat? Thank you.

[mayujsw]

OK, wait for a min

and we find that each time we reboot the android, it could only work again after we re-push the 2 jar files, and re-run "adb shell uiautomator runtest bundle.jar uiautomator-stub.jar -c com.github.uiautomatorstub.Stub" . While on KitKat, we do not need these step, uiautomator can be always workable no matter reboot or not...

[xiaocong]

Very strange... Python wrapper should have done all the same steps automatically. Please help double check if the uiautomator's version in your working environment is 0.1.32.

[mayujsw]

yes, we download from here : https://pypi.python.org/pypi/uiautomator/0.1.32

[mayujsw]

From usage perspective, the difference vs. KitKat now is that we need to push 2 JAR files/run these 2 jar through uiautomator everytime we boot up android ..

[mayujsw]

Just tried on Nexus7 Android L, also met connect reset by peer error

[xiaocong]

logcat please.

[mayujsw]

The first time, it works as below :

d.info {u'displayRotation': 1, u'displaySizeDpY': 600, u'displaySizeDpX': 960, u'displayWidth': 1920, u'productName': u'razor', u'currentPackageName': u'com.android.launcher', u'sdkInt': 20, u'displayHeight': 1104, u'naturalOrientation': False}

Then we reboot, try again, it does not work anymore, logcat is attached below as well:

d.info Traceback (most recent call last): File "", line 1, in File "/usr/local/lib/python2.7/dist-packages/uiautomator/init.py", line 519, in info return self.server.jsonrpc.deviceInfo() File "/usr/local/lib/python2.7/dist-packages/uiautomator/init.py", line 400, in wrapper server.start() File "/usr/local/lib/python2.7/dist-packages/uiautomator/init.py", line 440, in start raise IOError("RPC server not started!") IOError: RPC server not started!

logcat:

[henrydeng]

the change in 0.1.32 version of below codes may lead to fail to push jar package to mobile. I remove this change and the server will be ok

• cmd_line = ["-s", self.device_serial()] + list(args)

•  cmd_line = ["-s", "'%s'" % self.device_serial()] + list(args)

•  return dict([s.split() for s in out[index + len(match):].strip().splitlines() if s.strip()])

• return dict([s.split("\t") for s in out[index + len(match):].strip().splitlines() if s.strip()])

[xiaocong]

Thank @henrydeng. Do you know how it fails?
