I have implemented the AGSL code written in the documentation:

@Language("AGSL")
private static final String COLOR_SHADER_SRC =
    "half4 main(float2 fragCoord) {\n" +
            "return half4(1.0,0.0,0.0,1.0);\n" +
            "}";

private static final RuntimeShader fixedColorShader  = new RuntimeShader(COLOR_SHADER_SRC);
private static final Paint shaderPaint = new Paint();

and in the constructor:

shaderPaint.setShader(fixedColorShader)

But when I call with some canvas:

this.canvas.drawPaint(shaderPaint);

I get:

[SurfaceView[com.example.mandebrotset/com.example.mandebrotset.MainActivity]#1(BLAST Consumer

1. I tried moving from API 33 to Android version 14 with SDK API 34 but nothing changed.

2. I enabled android:hardwareAccelerated="true" at the manifest in the whole Application, still no change.

3. The canvas from SurfaceHolder is given by the surfHolder.lockHardwareCanvas(). No change.
