Androidx RenderScript not run android api<19

I have use androidx with blur image, but when run android api< 19 crash app. When i run with android>19, i run normal,not crash app and if i use android normal with "android.support.v8.renderscript" no crash app. At build.gradle. I have add :

  renderscriptTargetApi 18
    renderscriptSupportModeEnabled true

Code app:

public static Bitmap blurBitmap(Bitmap bitmap,
                                float radius) {        //Create renderscript
    RenderScript
            rs = RenderScript.create(MyApplication.getInstance());

    //Create allocation from Bitmap
    Allocation allocation = Allocation.createFromBitmap(rs,
            bitmap);
    Type t = allocation.getType();

    //Create allocation with the same type
    Allocation blurredAllocation = Allocation.createTyped(rs,
            t);

    //Create script
    ScriptIntrinsicBlur blurScript = ScriptIntrinsicBlur.create(rs, Element.U8(rs));

    //Set blur radius (maximum 25.0)
    blurScript.setRadius(radius);
    //Set input for script
    blurScript.setInput(allocation);
    //Call script for output allocation
    blurScript.forEach(blurredAllocation);

    //Copy script result into bitmap
    blurredAllocation.copyTo(bitmap);

    //Destroy everything to free memory
    allocation.destroy();
    blurredAllocation.destroy();
    blurScript.destroy();
    t.destroy();
    rs.destroy();
    return bitmap;
}

Edit: This issue is now fixed in the latest build tools. I've verified this by upgrading compile sdk to API 29 and build tools to 29.0.2.

This has nothing to do with your implementation. It's a bug in the androidx library and in fact, it happens for me even on API 21 so it might have a bigger impact than you've experienced.

Someone has already filed issues here and here. I've been following on the issue for quite sometime unfortunately there isn't much progress going on. This is currently a showstopper for me to migrate to AndroidX for many of my projects.

The Element.U8 argument for ScriptIntrinsicBlur.create() is not correct.

The ScriptIntrinsicBlur is expecting an Allocation with elements of type Element.U8, but a Bitmap-backed Allocation has elements of type Element.RGBA_8888 (a.k.a Element.U8_4).

try:

ScriptIntrinsicBlur.create(rs, Element.RGBA_8888(rs))

or in general:

ScriptIntrinsicBlur.create(rs, allocation.getElement())
