I have Shield TV and Pixel C. Both seem to me to have the same hardware Tegra X1. If I create a native application with the wizard in Nsight Tegra and then start a debugging session - on the Shield TV debugging works. On the Pixel C - I get the same error message as in this post: [url]https://devtalk.nvidia.com/default/topic/897667/cannot-launch-gdbserver/[/url]
“Cannot launch gdbserver: all options have failed.”
“Failed to attch: Failed to start debug server on the device”

Well, this is unrelated to the above but still. If I create an Android application with the wizard (java only) on Pixel C and Shield TV:

Hi Zimgam,
From the logcat log, It seems caused by SELinux policy enforced on that device:
06-03 17:15:04.848 4054 4054 W run-as : type=1400 audit(0.0:98): avc: denied { execute } for name=“gdbserver” dev=“dm-2” ino=114695 scontext=u:r:untrusted_app:s0:c512,c768 tcontext=u:object_r:shell_data_file:s0 tclass=file permissive=0
could you try disable SELinux enforcement via “adb shell setenforce 0”?
If it’s still occuring, please send us the log of Nsight Tegra at %APPDATA%NVIDIA Corporation\Nsight Tegra\Logs\Nsight Tegra.log and device OS info via adb shell getprop ?

Hello, Victor,
Thank you for your advice. I tried what you told me but I probably need to root the device. So I prefer to wait for the Android N to try then.
It appears to be a problem with Pixel C’s Android. Debugging is not possible even with Google’s Android Studio and LLDB, so I filed a bug report.
I am currently only researching Android/Shield as a second tier target platform for our product after we finish our main target platforms later this year. I hope that the tools/Android will be in much better shape when we start porting to Shield and probably Vulkan on Shield too.

Does my issue have anything in common with this issue: [url]https://github.com/android-ndk/ndk/issues/118[/url]
Hi Zingam,
Could you send me your log? Just from the error message, it seems to be caused by access provilidge issue like the link you mentioned.

This is a problem with Pixel C and was fixed in Android N. Now all debugging on Pixel C with Android N is functional. Java debugging still does not work on SHIELD TV as the bug in 6.0.1 is ART related and Google won’t fix it for API 23.
Now I just hope that you’ll release an update to Android N for SHIELD TV soon and Nsight Tegra with NDK 12/13 as soon as possible.
I couldn’t get Nsight Tegra to work with NDK 12. So I just hope we won’t need to wait for support that long after new NDK is released.
This is the bug if you are interested: Google Issue Tracker
Thank you very much, Victor!
NDK-r12b support would be in the next release, Please be patient.
