android-vulkan-tutorials's Introduction

Tutorial Samples

A set of samples to illustrate Vulkan API on Android with Android Studio To build on windows for tutorial02/03, copy/install ndk-r12 ( or better ) to a directory close to root dir ( C: ) to workaround command path 260 character limit issue; see tutorial02/03's build.gradle for details. To Build samples:

Inside Andriod, menu File --> New --> Import Project
Find your sample's build.gradle and open it This will force andrioid studio to create local.properties file to config your SDK and NDK location; if you see error during importing, open local.properties file and correct the NDK and SDK location, then re-sync.

Other Resources: Additional Android Studio/NDK samples:

Tutorial 1 - Load Vulkan
- create a vulkan device
Tutorial 2 - Prebuilt Layers
- create a vulkan device with vulkan validation layers
Tutorial 3 - Traceable Layers
- create a vulkan device with validation layers that could be traced. Refer to README.md under its directory
Tutorial 4 - First Window

App fails with "FAILED BINDER TRANSACTION" when run in emulator

Moved to: http://stackoverflow.com/questions/42581120/how-to-create-and-run-an-example-vulkan-app-that-on-the-android-emulator

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:

I've just downloaded the Vulkan tutorial and build in AS 3.4

I get this error when trying to run in emulator:

tutorial06 shaderc ndk build error

I was building shaderc with ndk r23 with command line given in tutorial 06 readme, it gives error when doing combine:

"[arm64-v8a] Combine: libshaderc_combined.a <= libglslang.a libOGLCompiler.a libOSDependent.a libshaderc.a libshaderc_util.a libSPIRV.a libHLSL.a libSPIRV-Tools.a libSPIRV-Tools-opt.a"
'D:/ProgramFiles/android-ndk-r23b/build//../toolchains/llvm/prebuilt/windows-x86_64/bin/aarch64-linux-android-ar' is not recognized as an internal or external command,
operable program or batch file.
make: *** [D:/ProgramFiles/android-ndk-r23b/sources/third_party/shaderc/Android.mk:77: obj/local/arm64-v8a/libshaderc_combined.a] Error 1

I have checked there is no file named "aarch64-linux-android-ar" with any extension but only "aarch64-linux-android-as.exe" presents, is there any version mismatch problem I'm possibly encountering? Thanks in advance.

Image layout not switched for filling data and rendering

Tested on Pixel C with Android 7.1.2, trace analyzed with GAPID: https://github.com/google/gapid

The layout of the texture image in tutorial 6 does not change for initial data copying and rendering. vkCmdPipelineBarrier should be added to switch the layout.

VkQueueFamilyProperties not queried before VkCreateDevice

Not a big issue, but different platform may have different queue families and the QueueFamily[0] may not support graphics rendering.

Change Image layout for swapchain images

per @bbilodeau: according to standard, swapchain image layout transition is also necessary.

Could you please update versions?

This doesn't work with NDK23.

gradlew commands fail with: "failed to find target with hash string 'android-N'"

I have already installed SDK 23 and 24 through Studio, created a working API 24 emulator, and have NDK 12.

Whenever I run a gradlew command, e.g.:

cd tutorial01_load_vulkan
./gradlew clean

it fails with:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Exception thrown while executing model rule: NdkComponentModelPlugin.Rules#createNativeLibrary > create(vktuts) > components.vktuts.getBinaries() > withType()
   > Exception thrown while executing model rule: BaseComponentModelPlugin.Rules#createAndroidComponents
      > failed to find target with hash string 'android-N' in: /home/ciro/android-sdk

Same error message on SO: http://stackoverflow.com/questions/35937530/android-studio-2-1-preview-failing-to-find-target-with-hash-string-android-n

App crashes when switching on and off the screen

Tutorial04 First Window, built on Android 10 and run in Pixel 3a.
Gradle version 3.5.1

Reproduce step:

Run on debug mode
See the empty blue screen to confirm running.
Start turning on and off the screen by pressing the power button frequently.
Observe the crash via Logcat

The error logs I have:

How to use dlopen() on Android 8?

In my test ndk app, dlopen() reutrn nullptr.

Java_com_github_rpg3d_sword2android_MainActivity_runGame(JNIEnv* env, jobject /* this */)
{

    void* handle = dlopen("libvulkan.so", RTLD_NOW|RTLD_LOCAL);
    char* loaderror = (char *) dlerror();
    Game game;
    game.run();

}

Initial layout of image must be either UNDEFINED or PREINITIALIZED

The VkImageCreateInfo does not specifies what value will be there in the create_info. According to the spec, the initial layout must be either VK_IMAEG_LAYOUT_UNDEFINED or VK_IMAGE_LAYOUT_PREINITIALIZED.

Validation Layer source code changes in NDK, tutorial3 needs to be updated

Some layers are deprecated ( like VKLayer_image ), the source code is not there anymore in the latest NDK, tutorial 3 will not build. Things to be done:

Find out from which NDK version the source is removed and update the layerlib build script
Update the layer and extension enabling code as current Vulkan already deprecated the device layers ( install for instance only, automatically apply to devices )

Cannot build using NDK 21.4

Using tutorial03_traceable_layers requires the following file to exist inside $NDK/sources/third_party/ but that file (and possibly more files) no longer exist in NDK 21.4: vk_layer_table.cpp

Replace `ALooper_pollAll` with `ALooper_pollOnce`

ALooper_pollAll has been (soft) removed from the NDK because the implementation has a race so it can't be used safely. ALooper_pollOnce should be used instead. I'll be updating the main ndk-samples repo soon with examples of how to do that.

no app modules

CMake Error

CMake can not determine linker language for target: vktuts
Studio 2.3.1
NDK 14.1.3816874

Sample of how to use it within live wallpaper?

Maybe show an image ?
Or a video?

validation layers changed in NDK18, need to update layer build sample

Segmentation fault when Tutorial 05 is closed

Hi!!

I found that when the app of the tutorial 5 is closed, I get a segmentation fault.

I think that this line is causing it. Because it is cleaning the memory allocate by the vkImages that will also be cleaned when destroying the swapchain.

If you take a look at the Vulkan toturial, you will see this:

"The images were created by the implementation for the swap chain and they will be automatically cleaned up once the swap chain has been destroyed, therefore we don't need to add any cleanup code."

Lint error when building triangle example

org.gradle.api.GradleException: Lint found fatal errors while assembling a release target.

To proceed, either fix the issues identified by lint, or modify your build script as follows:
...
android {
    lintOptions {
        checkReleaseBuilds false
        // Or, if you prefer, you can continue to check for errors in release builds,
        // but continue the build even when errors are found:
        abortOnError false
    }
}

Create memory management sample

vertex shader can't get all input data

I have my Vertex data defined like this:
struct Vertex{
glm::vec4 pos;
glm::vec2 texcoord;
glm::vec2 texcoordex;
float alpha;
float idx;
};

my problem is: vertex buffer has read all data, but vertex shader only gets the first one pos as input, others are 0.0f

vertex shader input
layout (location = 0) in vec4 pos;
layout (location = 1) in vec2 attr;
layout (location = 2) in vec2 attrex;
layout (location = 3) in float alph;
layout (location = 4) in float id;

some code snippets

VkVertexInputBindingDescription vertex_input_bindings{
.binding = 0,
.stride = sizeof(Vertex),
.inputRate = VK_VERTEX_INPUT_RATE_VERTEX,
};
VkVertexInputAttributeDescription vertex_input_attributes[5]{
{
.binding = 0,
.location = 0,
.format = VK_FORMAT_R32G32B32A32_SFLOAT,
.offset = offsetof(Vertex, pos),
},
{
.binding = 0,
.location = 1,
.format = VK_FORMAT_R32G32_SFLOAT,
.offset = offsetof(Vertex, texcoord),
},
{

.offset = offsetof(Vertex, alpha),
},
{
.binding = 0,
.location = 4,
.format = VK_FORMAT_R32_SFLOAT,
.offset = offsetof(Vertex, idx),
}};

VkPipelineVertexInputStateCreateInfo vertexInputInfo{
.sType = VK_STRUCTURE_TYPE_PIPELINE_VERTEX_INPUT_STATE_CREATE_INFO,
.pNext = nullptr,
.vertexBindingDescriptionCount = 1,

.pVertexAttributeDescriptions = vertex_input_attributes,
};

VkDeviceSize offset = 0;
vkCmdBindVertexBuffers(render.cmdBuffer_[bufferIndex], 0, 1, &buffers.vertexBuf_, &offset);

How can I solve the problem? Thanks for any help.

tutorial06_texture build error

gradle builds four different abi libs: armeabi-v7a, arm64-v8a, x86, x86-64, but only armeabi-v7a type libshaderc.a is downloaded. Then there's the link error:

How to tell the cdep to download all libs we need? Change the cdep.sha256 to something like this?

Texture2D & Sampler instead of Sampler2D crashing while creating Pipeline

I had the HLSL source with Texture2D and Sampler separately (not using Sampler2D basically)... SPIRV generated through that works fine on Windows but it fails on Android while creatingGraphicsPipeline. Is it a known issue ?
If not, can u please share a tutorial/sample where instead of using Sampler2D you have used Texture2D and Sampler separately. I see this crashing on Samsung S7 as well as Pixel XL
