 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.

 Demonstrate how to use validation layers prebuilt from [Validation layer repo][1]
 
-## Pre-requirement:
----------------
-1. Download prebuilt validation layer android-binaries-*.zip from [Khronos repo][1]
-1. unzip to $this-project-root/vvl-libs
+This sample automatically downloads prebuilt validation layer zip from [Khronos repo][1],
+unzips it, and adds the validation layer library to the project's jniLibs.
 
 ## Added steps from previous example
 1. Use vulkan wrappers in common/vulkan_wrapper directory.
-1. Add the validation layer into gradle build to pack it into apk.
-1. (Optional but nice to have)Confirm the validation layer "VK_LAYER_KHRONOS_validation" is available with `vkEnumerateInstanceLayerProperties()`. 
-1. Enable the validation layer and "VK_EXT_debug_report" when creating instance.
-1. Register debug callback implemented in "VK_EXT_debug_report" with vkCreateDebugReportCallbackEXT(). Note that application could also use "VK_EXT_debug_utils" implemented in the validatio layer.

 # Tutorial 03 - traceable_layers
+
 This has the same functionality as [Tutorial 2](../tutorial02_prebuild_layers), but building the validation layers
 from the Khronos Group Validation Layer source code hosted on [the github repo](https://github.com/KhronosGroup/Vulkan-ValidationLayers.git).
+
 The benefit is:
-- you could trace into validation layers.
-- you could observe the detailed status when validation layer finds issues in your app.
+- You can peek/step into validation layers.
+- You can observe the detailed status when validation layer finds issues in your app.
 
-Validation layers are stable now, this should be a good help to developers who likge to know
-more about validation layers inside.
+This can be useful for developers who want to know more about validation layers.
 
 # Background
-Layer source status:
-- For NDK version <= r21, there are multiple layers for Android; NDK keeps a snapshot of layer source code and the binaries
-- For NDK22 layers are consolidated into one layer: VkLayer_khronos_validation; NDK keeps a snapshot of layer source code and the binary
-- For NDK version >= r23, layer source and binary are not available anymore.
 
-We recommend developers to get the validation layer source and binary releases directly from
+Building validation layers from sources currently requires NDK r25c or newer.
+
+Developers should get the validation layer source from
 [the github repo](https://github.com/KhronosGroup/Vulkan-ValidationLayers.git).
 
 
 # Build Instructions

-code(to force it build before app).The validation layer source code needs to be pulled in on command line before building the sample:

+In this sample, the validation layers is wrapped into a gradle library module called `layerlib`. The `app`
+module depends on this `layerlib` module.
+
+The validation layer source code needs to be pulled in on command line before building the sample. Steps:
+
 1. cd tutorial03_traceable_layers/layerlib
 2. git clone --recursive https://github.com/KhronosGroup/Vulkan-ValidationLayers.git
-3. cd Vulkan-ValidationLayers/build-android
-4. ./update_external_sources_android.sh --no-build
-    (use the update_external_sources_android.bat for Windows OS)
-5. Now, at this point, open this sample with Android Studio with "Open an Existing Project" option
-6. Build the project, and start debugging(Run > Debug App). It takes about 20 minutes to build layers, so be patient
-
-Once app triggers validation layer assert(embedded on purpose inside this sample in the app), you could see the stack frames
-inside Studio IDE., inside the debug window, you would see all validation layer variables when the app error is validated.
+3. Make sure the `cmake` binary is on your `PATH` environment variable.
+4. Open this sample with Android Studio with "Open an Existing Project" option
+5. Sync the project with Gradle Files. This can take 3-5 minutes to sync.
+6. Build the project, and start debugging (Run > Debug App). It can take 5-10 minutes to build.
 
-This sample is not tested on windows, it should work.
+Once the app triggers validation layer assert (embedded on purpose inside this sample in the app), you can see the stack frames
+in the Android Studio IDE debugger. You can also step into the validation layer, and check the values of all variables.
 
-## future work
-- Automically pull the source code automatically in gradle, but gradle's 'ndkBuild path' is evaluated before source code pulling,
-hence errors out, need help to get it done.
-- automatically run update_external_sources_android.sh. probably needs a gradle task to do it.
+## Future Work
+- Automatically pull the source code automatically in Gradle.

 ```
+
+Replace the `ANDROID_NDK`, `ANDROID_STL`, and `APP_PLATFORM` with appropriate values, such as the
+path to NDK r25.1, `c++_static`, and `latest`.
+
+This build step can take 3-5 minutes. If you only care about a single ABI, setting `APP_ABI`
+accordingly will reduce this build time by half.

+Known Issues
+------------
+
+On Windows, you may encounter the following build error during `shaderc` compilation:
+
+```
+$ANDROID_NDK/toolchains/llvm/prebuilt/windows-x86_64/bin/llvm-ar.exe: error: script line 1: unknown command: "create
+```
+
+In this case, edit the following generated files and remove all copies of double quotes (i.e., the
