Not based on JOGL apparently, but JOGL also supports Android:

Vulkan

Looks like C++ only?

Samples:

• https://github.com/googlesamples/android-vulkan-tutorials, fails with:
  • googlesamples/android-vulkan-tutorials#11 http://stackoverflow.com/questions/35937530/android-studio-2-1-preview-failing-to-find-target-with-hash-string-android-n
  • and then googlesamples/android-vulkan-tutorials#13
• https://github.com/googlesamples/vulkan-basic-samples/ port of https://github.com/LunarG/VulkanSamples, available from Android Studio, but import did not work last time I tried...

TODO: supported or not?

RenderScript

The official OpenCL for Android: http://stackoverflow.com/questions/14385843/why-did-google-choose-renderscript-instead-of-opencl
