CTS not executing for package: android.nativemedia.sl

[Slavik Kuper]

Hello. I'm trying to run 4.1_r3 CTS package: android.nativemedia.sl for a device compiled from AOSP 4.1.2 but I face the following error:

06-25 19:49:51 I/0123456789ABCDEF: Test package android.nativemedia.sl started

06-25 19:49:51 I/0123456789ABCDEF: -----------------------------------------

If I manually(using adb shell) create the /data/local/tmp/cts-native-tests directory including changing permissions to 777 in all path chain. I get a different error:

06-25 19:57:46 I/0123456789ABCDEF: Test package android.nativemedia.sl started

I also tried to strace adbd, and look at the logcat but couldn't find anything of use. What else can I try?

OK. I'll share how I solved it by answering myself.

The tries to push : 'NativeMediaTest_SL' file to /data/local/tmp/cts-native-tests

But for some reason, CTS code uses FILE class to build the string and then get its path, actually push :

'/data/local/tmp/cts-native-tests/NativeMediaTest_SL' to '/'.

So my Windows JVM changes the path so slashes become backslashes and the push fails.
