How to solve ClassNotFoundException on uiautomator startup?

I'm trying to create GUI tests for my app with the provided tool(s) from the android-sdk for my app. For the start i've set up a project, as described in http://developer.android.com/tools/testing/testing_ui.html in "Configure your development environment". Currently i've taken the example test from http://developer.android.com/tools/testing/testing_ui.html#sample and put it inside the project UITestsMyAppBasis, in the the package com.MyApp.guitest

the command ant build runs succesfully and i get a jar file in the bin directory of my project. But when i try to start it via:

adb push ./UiTestsMyAppBasis.jar /data/local/tmp
adb shell uiautomator runtest UITestsMyAppBasis.jar -c com.MyApp.guitest

i get the console output:

INSTRUMENTATION_RESULT: shortMsg=java.lang.RuntimeException
INSTRUMENTATION_RESULT: longMsg=com.MyApp.guitest
INSTRUMENTATION_CODE: 0

and the logcat output:

java.lang.RuntimeException: com.MyApp.guitest

i'm using an android emulator with

Setting the chmod on /data/dalvik-cache as described in https://stackoverflow.com/a/13805869/1171328 didn't change the output.

Best way to check this problem is to run this command without using -c # and check if it works. If it works check for the class name that it prints in the terminal is the one that's used with -c

adb shell uiautomator runtest UITestsMyAppBasis.jar

I believe, this should solve your problem:

-c parameter is used to run the class and not package. so it should be:

adb shell uiautomator runtest UITestsMyAppBasis.jar -c com.MyApp.guitest.<class_name>
