App fails with "FAILED BINDER TRANSACTION" when run in emulator
cirosantilli opened this issue · 7 comments
After #12 I have SDK 24 preview 4, NDK 12 and either a Nexus 6P or Nexus One image.
Tutorial 1 builds and installs, but when I try to run it it breaks immediately with:

emulator may not have the vulkan support, they only support openGL.
@ggfan hmmm, ping me if you find a link on that.
So the only way to play with Vulkan on Android without enterprise internal tools is to get Galaxy S7? 😢
I do not have any link to myself. my emulator will not work. If it works that is a pleasant surprise.
a list of device is posted here:

it might be useful to you. you might also debug and trace into code to see where it fails, mostly it should failed at find no vulkan device [ my guess ]. Closing this one, feel free re-open if needed. Thanks
@ggfan I debug into code, it shows that gpuCount is still zero after vkEnumeratePhysicalDevices was called.
// Find one GPU to use:
// On Android, every GPU device is equal -- supporting graphics/compute/present
// for this sample, we use the very first GPU device found on the system
uint32_t gpuCount = 0;
CALL_VK(vkEnumeratePhysicalDevices(device.instance_, &gpuCount, nullptr));
I use Nexus 5X API level 25, and My computer GPU is nvidia geforce gtx 1050, it supports vulkan.
I think maybe there is something wrong in the android vulkan implement for emulator, or something wrong with the emulator.
Because vkEnumeratePhysicalDevices is a function pointer, i can't debug into it.
There is no emulator for Vulkan: I have not heard any even for stand alone emulator on desktop, would not image vulkan in Android emulator.
confirmed: no vulkan in emulator now. Hopefully there will be one in the future, need to find a vulkan enabled device before that.
Could you add your source which says that the emulator doesn't support vulkan?
Is a support planned?
Maybe add this information (or be a bit more specific) to the Readme?
A emulator check in the code and a more descriptive error message would be also cool.
