Loading of ScriptC script failed / cannot load library - Renderscript Android

Question

I get the following error message:

I guess that this message is created by int id being 0 in ScriptC_mono.java although it should be R.raw.mono, but I cannot find out why. Here are my *.rs and MainActivity.java files:

MainActivity:

import android.app.Activity;
import android.os.Bundle;
import android.graphics.BitmapFactory;
import android.graphics.Bitmap;
import android.support.v8.renderscript.*;
import android.widget.ImageView;

public class HelloCompute extends Activity {
private Bitmap mBitmapIn;
private Bitmap mBitmapOut;

private RenderScript mRS;
private Allocation mInAllocation;
private Allocation mOutAllocation;
private ScriptC_mono mScript;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    mBitmapIn = loadBitmap(R.drawable.data);
    mBitmapOut = Bitmap.createBitmap(mBitmapIn.getWidth(), mBitmapIn.getHeight(),
                                     mBitmapIn.getConfig());

    ImageView in = (ImageView) findViewById(R.id.displayin);
    in.setImageBitmap(mBitmapIn);

    ImageView out = (ImageView) findViewById(R.id.displayout);

    createScript();
    out.setImageBitmap(mBitmapOut);
}


private void createScript() {
    mRS = RenderScript.create(this);

    mInAllocation = Allocation.createFromBitmap(mRS, mBitmapIn,
                                                Allocation.MipmapControl.MIPMAP_NONE,
                                                Allocation.USAGE_SCRIPT);
    mOutAllocation = Allocation.createFromBitmap(mRS, mBitmapOut,
                                                 Allocation.MipmapControl.MIPMAP_NONE,
                                                 Allocation.USAGE_SCRIPT);

    mScript = new ScriptC_mono(mRS, getResources(), R.raw.mono);

    mScript.forEach_root(mInAllocation, mOutAllocation);
    mOutAllocation.copyTo(mBitmapOut);

    mScript.destroy();
}

private Bitmap loadBitmap(int resource) {
    final BitmapFactory.Options options = new BitmapFactory.Options();
    options.inPreferredConfig = Bitmap.Config.ARGB_8888;
    return BitmapFactory.decodeResource(getResources(), resource, options);
}}

Mono.rs:

#pragma version(1)
#pragma rs java_package_name(com.android.example.hellocompute)

rs_allocation gIn;
rs_allocation gOut;
rs_script gScript;

const static float3 gMonoMult = {0.299f, 0.587f, 0.114f};

void root(const uchar4 *v_in, uchar4 *v_out, const void *usrData, uint32_t x, uint32_t y) {
float4 f4 = rsUnpackColor8888(*v_in);

float3 mono = dot(f4.rgb, gMonoMult);
*v_out = rsPackColorTo8888(mono);
}

void filter() {
rsForEach(gScript, gIn, gOut, 0);
}

Answer 1

I finally found a solution:

I simply used ScriptIntrinsic and modified a matrix with the specific red components using the method setColorMatrix(3fMatrix m) in ScriptIntrinsicColorMatrix.

Thanks for all of your ideas, this works for me!

Answer 2

This is the same problem that will be fixed in the next SDK release (many others have hit it due to missing rsForEach() and other functions).
