• SET/export theANDROID_SDK_HOME environment variable. Its value should be the root of the Android SDK. The Android NDK must also be installed under the root, in the defaultndk-bundle subdirectory.
• Runant compile-templates. This will take 1-2 minutes.
• Runant aar. This will produce anlwjgl.aar file in thebin/android/ folder.
• Copylwjgl.aar to theandroid-test repository, in thelwjgl folder.

Build instructions for the Android demos:

Installation of Vulkan validation layers:

• Create a JNI library folder for the target architecture. For example:
  • hellovulkan/src/main/jniLibs/arm64-v8a/ or
  • hellovulkan/src/main/jniLibs/armeabi-v7a/
• Copy the shared libraries from the corresponding folder in the Android NDK. For example:
  • <sdkroot>/ndk-bundle/sources/third_party/vulkan/src/build-android/jniLibs/arm64-v8a/ or
  • <sdkroot>/ndk-bundle/sources/third_party/vulkan/src/build-android/jniLibs/armeabi-v7a/
• Set theVALIDATE variable totrue inHelloVulkan.java:53
