Vulkan examples on Android

Vulkan on Android

Since Vulkan is not yet part of the Android OS (like OpenGL ES) the library and function pointers need to be dynamically loaded before using any of the Vulkan functions. See the vulkanandroid.h and vulkanandroid.cpp files in the base folder of the repositoy root for how this is done.

Device support

• To run these examples you need a device with an Android image that suports Vulkan
• Builds currently only support arm-v7, x86 may follow at a later point
• Android TV leanback launcher is supported, so the examples will show up on the launcher
• Basic gamepad support is available too (zoom and rotate)
• Touch controls are not yet implemented, same for screen rotations

Building

Requirements

• Android NDK r11b (or newer) - Somewhere in your search path
• Examples are built against API level 23 (requires the SDK Platform installed)
• Batch files for building are provided for windows only, with linux to be added at some point

Building the Examples

Complete set

Please note that building (and deploying) all examples may take a while

Build only

build-all

This will build all apks and puts them into the bin folder.

Build and deploy

install-all

This will build all apks and deploys them to the currently attached android device.

Single examples

These are for building and/or deploying a single example.

Build only

Call build(.bat) with the name of the example to build, e.g. :

build triangle

This will build the apk for the triangle example and puts it into the bin folder.

Build and deploy

build triangle -deploy

This will build the apk for the triangle example and deploys it to the currently attached android device.

Removing

A batch file for removing all installed examples is provided in case you installed all of them and don't want to remove them by hand (which is especially tedious on Android TV).

uninstall-all

This will remove any installed Android example from this repository from the attached device.
