When i run my android UIAutomator code, it shows error

Question

When I run my android UIAutomator code, it shows following error.

INSTRUMENTATION_RESULT: shortMsg=java.lang.RuntimeException
INSTRUMENTATION_RESULT

Answer 1

If you get a ClassNotFindException while running your uiautomator tests :

Some of us my get this error because their ROM puts the folder /data/dalvik-cache in read-only mode. That happened to me with Cyanogen for a S3.

In that case type, in bash :

adb shell 
su
chmod 777 /data/dalvik-cache
exit

rerun your tests and that should work. As dalvik-cache is locked for apps, uiautomator can't ask dalvik to unzip the jar of your tests and dalvik won't find the its classes.
