错误渲染脚本 Android Studio 2.0

Question

今天，我收到了来自 Android Studio 的 2.0 版更新。更新完成后，我构建应用程序，但在构建 gradle 中遇到错误消息

Error:Renderscript support mode is not currently supported with renderscript target 21+

我正在搜索并通过替换找到解决方案

renderscriptTargetApi 21
renderscriptSupportModeEnabled true

到

renderscriptTargetApi 20
renderscriptSupportModeEnabled true

构建成功，但是当我运行应用程序时，应用程序崩溃显示 logcat ：

代码过程模糊：

import android.content.Context;
import android.graphics.Bitmap;
import android.support.v8.renderscript.Allocation;
import android.support.v8.renderscript.Element;
import android.support.v8.renderscript.RenderScript;
import android.support.v8.renderscript.ScriptIntrinsicBlur;

/**

public class BlurImageUtils {
    public static Bitmap blurRenderScript(Context context, Bitmap smallBitmap, int radius) {

        try {
            smallBitmap = RGB565toARGB888(smallBitmap);
        } catch (Exception e) {
            e.printStackTrace();
        }
        Bitmap bitmap = Bitmap.createBitmap(
                smallBitmap.getWidth(), smallBitmap.getHeight(),
                Bitmap.Config.ARGB_8888);

        RenderScript renderScript = RenderScript.create(context);

        Allocation blurInput = Allocation.createFromBitmap(renderScript, smallBitmap);
        Allocation blurOutput = Allocation.createFromBitmap(renderScript, bitmap);

        ScriptIntrinsicBlur blur = ScriptIntrinsicBlur.create(renderScript,
                Element.U8_4(renderScript));
        blur.setInput(blurInput);
        blur.setRadius(radius); // radius must be 0 < r <= 25
        blur.forEach(blurOutput);

        blurOutput.copyTo(bitmap);
//        renderScript.destroy();

        return bitmap;

    }

    private static Bitmap RGB565toARGB888(Bitmap img) throws Exception {
        int numPixels = img.getWidth() * img.getHeight();
        int[] pixels = new int[numPixels];

        //Get JPEG pixels.  Each int is the color values for one pixel.
        img.getPixels(pixels, 0, img.getWidth(), 0, 0, img.getWidth(), img.getHeight());

        //Create a Bitmap of the appropriate format.
        Bitmap result = Bitmap.createBitmap(img.getWidth(), img.getHeight(), Bitmap.Config.ARGB_8888);

        //Set RGB pixels.
        result.setPixels(pixels, 0, result.getWidth(), 0, 0, result.getWidth(), result.getHeight());
        return result;
    }
}

当我将 IDE 更新到 2.0 时出乎意料！

请给我一些解决方案。谢谢大家！！！

与renderscriptTargetApi 相关的错误已在 gradle-plugin 2.1.0 和 Build-Tools 23.0.3 中修复。 请尝试一下：

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.0'
    }
}


android {
    compileSdkVersion 23
    buildToolsVersion "23.0.3"
    ...
}

“未知故障”似乎很奇怪。你有关于它的日志吗？
