Android UI testing: "adb shell uiautomator" throws error, "uiautomator" in "adb shell" works -

i compile , run android ui black-box tests using command-line tools on windows. wrote uiautomatortestcase, built it, , uploaded /data/local/tmp/. verified jar file copied latter directory.

if type

adb shell

and type

uiautomator runtest mytest.jar –c com.example.mytest

at adb shell prompt, test runs successfully. far good.

the problem if combine these 2 steps , type

adb shell uiautomator runtest mytest.jar –c com.example.mytest

then next error:

error: /data/local/tmp/ľc not exist

according documentation, should work. error same on windows 7 pro 32-bit hun , on windows 8.1 pro 64-bit eng. device samsung galaxy s3 mini (gt-i8190), running android 4.1.2 (api level 16).

what doing wrong?

i suppose,

adb shell $ <command> same adb shell <command>. i've never encountered discrepancy in regards.

please seek adb kill-server , adb start-server

please seek adb -s <device_id> shell <command> can find <device_id> adb devices

can please allow know output of adb version?

android shell command-line adb uiautomator
