the first thing on the page should probably be the deprecation notice, and then just a link to the migration samples, with the rest only of historical interest now?

Hello,

In downloading & running the example, I had gradle fail to sync due to the following dependency in the application gradle file:

compile files('renderscript-v8.jar')

Commenting out the dependency allowed the app to build and run. I didn't notice any side effects of that, so I think it might be useful to remove that dependency unless there's something I'm not realizing that went wrong by doing so. The repository doesn't have that file which is what creates the issue with the dependency.

Thanks,

Corey

I find a bug in the demo, which compare renderscript , renderscriptInstrinct, Vulcan .
The way you calculate time， Only include render time 。
if we calculate time include render time and parpare time ， I find that renderscriptInstrinct is the fastest way to blur。
Can we reduce the parpare time when we use Vulcan blur

I notice that code "// We prefer the workgroup size to be a multiple of 4." , why should we do this?

I'm working with the Khronos Vulkan samples team and there was a request for samples to show how to use external memory for cooperating with other APIs. It was suggested that we explore repurposing this sample as it is very relevant to the Vulkan audience. LMK if this is something we can consider pursuing. Would involve porting to the Vulkan Samples framework, but we could potentially find resources for that if needed. Thanks.

Cant compile "compile files('renderscript-v8.jar')" due to missing the file and you have two defaultConfig that will cause problem in the future In the build.gradle file. Please update the gradle file. Thanks

This fixes the project sample to actually compile out of the box. This
also adds a .gitignore files for commonly generated files by the IDE.
This fixes issue #1 and fixes issue #4.

To do some Renderscript performance benchmarking, i tried to run the sample on different devices like Nexus 6P & Samsung S7. I changed the default image to a 12 MP image takes from Nexus 6P camera. When i launch app, it crashes with OutOfMemory error. Why are we creating so many Bitmaps & Allocations? How can i make it run?

I've got sigserv exception in my play console which points to pickPhysicalDeviceAndQueueFamily() method. Problem persist on
different devices (Oppo, samsung, doogee, lge, lenovo, vivo etc) with specific mediatek cpu's.
List of CPUS: Mediatek MT6765, Mediatek MT8768T, Mediatek MT6765V/CB, Mediatek MT6761, Mediatek MT6762, Mediatek MT8768T, Mediatek MT6779p90, Mediatek MT6779p95.

Any ideas to fix?

In the past, we had some live wallpapers by Google, made using Renderscript.
Renderscript was put aside after some time, not being used for such purposes.
Now as I've noticed Vulkan should replace them:
https://android-developers.googleblog.com/2021/04/android-gpu-compute-going-forward.html

And here we got a sample of this migration, according to the same blog.

Can you please provide samples of using it on the same live wallpapers apps we used to have?

I think one of them looked like this:

I'm getting this error when trying to install the RenderScriptMigrationSample app target API level '29' is out of range ('11' - '24')

First of all, cool sample! But I'm here to complain. I modified your sample like so:

int w = mBitmapIn.getWidth();
int h = mBitmapIn.getHeight();
Allocation allocation4 = Allocation.createTyped(mRS,
    new Type.Builder(mRS, Element.F32_4(mRS)).setX(w).setY(h).create());
mScriptMatrix.forEach(inAllocation, allocation4);
float[] float4 = new float[w * h * 4];
allocation4.copyTo(float4); // Works! I get RGBA float pixels!

Allocation allocation1 = Allocation.createTyped(mRS,
        new Type.Builder(mRS, Element.F32(mRS)).setX(w).setY(h).create());
mScriptMatrix.forEach(inAllocation, allocation1);
float[] float1 = new float[w * h];
allocation1.copyTo(float1); // Works! I get R float pixels!

Allocation allocation2 = Allocation.createTyped(mRS,
        new Type.Builder(mRS, Element.F32_2(mRS)).setX(w).setY(h).create());
mScriptMatrix.forEach(inAllocation, allocation2);
float[] float2 = new float[w * h * 2];
allocation2.copyTo(float2); // Works! I get RG float pixels!

Allocation allocation = Allocation.createTyped(mRS,
        new Type.Builder(mRS, Element.F32_3(mRS)).setX(w).setY(h).create());
mScriptMatrix.forEach(inAllocation, allocation);
float[] float3 = new float[w * h * 3];
// allocation.copyTo(float3); // Fails! Want RGB float pixels but Allocation is 4/3 too big.

It looks like the issue is in Renderscript itself so maybe this isn't the right place; if so can you direct me? Thanks!
From https://android.googlesource.com/platform/frameworks/base/+/master/rs/java/android/renderscript/Element.java they are special casing 3 channels to 4--why oh why?

Element(long id, RenderScript rs, DataType dt, DataKind dk, boolean norm, int size) {
    super(id, rs);
    if ((dt != DataType.UNSIGNED_5_6_5) &&
            (dt != DataType.UNSIGNED_4_4_4_4) &&
            (dt != DataType.UNSIGNED_5_5_5_1)) {
        if (size == 3) {
            mSize = dt.mSize * 4;
        } else {
            mSize = dt.mSize * size;
        }
    } else {
        mSize = dt.mSize;
    }
    mType = dt;
    mKind = dk;
    mNormalized = norm;
    mVectorSize = size;
}

An Update to Android Tools requires gradle version 2.10 or greater to work.

Also included a gitignore since there was not one in this project.

I failed to compile the script file saturation.rs. The error info. was

I've written an ImageProcessor that uses the new RenderEffect code from Android S. I would like to contribute it. Please allow me create a branch and a PR. I have already agreed to the Google CLA.
