android - 没有 rsDebug，RenderScript 代码无法工作

Question

我对 RenderScript 完全陌生。我试图获得 Romain Guy 在 http://www.youtube.com/watch?v=5jz0kSuR2j4 中展示的一个简单示例工作。

首先，这是代码。

主要 Activity .java

    package com.example.rsgray;

    import android.app.Activity;
    import android.graphics.Bitmap;
    import android.graphics.BitmapFactory;
    import android.os.Bundle;
    import android.renderscript.Allocation;
    import android.renderscript.RenderScript;
    import android.view.Window;
    import android.view.WindowManager;
    import android.widget.ImageView;
    import android.widget.ImageView.ScaleType;

    public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    ImageView iv = new ImageView(this);
    iv.setScaleType(ScaleType.CENTER_CROP);
    setContentView(iv);

    drawGrayScale(iv, R.drawable.tulips);
}

private void drawGrayScale(ImageView iv, int image) {
    Bitmap in = BitmapFactory.decodeResource(getResources(), image);
    Bitmap out = Bitmap.createBitmap(in.getWidth(), in.getHeight(), in.getConfig());

    RenderScript rs = RenderScript.create(MainActivity.this);
    Allocation inAlloc = Allocation.createFromBitmap(rs, in);
    Allocation outAlloc = Allocation.createTyped(rs, inAlloc.getType());

    ScriptC_gray script = new ScriptC_gray(rs, getResources(), R.raw.gray);
    script.set_in(inAlloc);
    script.set_out(outAlloc);
    script.set_script(script);

    script.invoke_filter();

    outAlloc.copyTo(out);
    iv.setImageBitmap(out);
}

灰色.rs

    #pragma version(1)
    #pragma rs java_package_name(com.example.rsgray)
    #pragma rs_fp_relaxed

    rs_allocation in;
    rs_allocation out;
    rs_script script;

    const static float3 gray = { 0.3f, 0.6f, 0.1f };

    void root(const uchar4* v_in, uchar4* v_out, const void* usrData, uint32_t x, uint32_t y) {
        rsDebug("gray.rs", rsUptimeMillis());
        float4 inPixel = rsUnpackColor8888(*v_in);
        float3 result = dot(inPixel.rgb, gray);
        *v_out = rsPackColorTo8888(result);
    }


    void filter() {
        rsForEach(script, in, out);
    }

最后是 AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.rsgray"
android:versionCode="1"
android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="16"
    android:targetSdkVersion="16" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.rsgray.MainActivity"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
</application>

</manifest>

res/drawable-nodpi 包含 tulips.jpg。您不会在 Romain Guy 的代码中找到我在 gray.rs 中添加的 rsDebug() 语句。

无论如何，无论是否使用 rsDebug()，代码都会编译。但是，当我尝试在设备上运行该应用程序时，问题就出现了。

我尝试在运行 Android 4.4 的 Nexus 4 上运行该应用程序。使用如图所示的代码，它工作正常，我得到了一个灰度图像。但是，如果我注释掉 rsDebug() 行，应用程序将无法运行。我只是黑屏。

这是 logcat 输出。

我无法理解调试语句如何影响应用程序的运行方式。任何关于我为什么会遇到这个问题的帮助将不胜感激。

这就是我的问题的第一部分。

第二部分:当我尝试在运行 Android 4.1.2 的 Galaxy Note 10.1 N8013 和另一台同样运行 Android 4.1.2 的 APQ8064 硬件上运行完全相同的代码时，应用程序无法运行。

这是我的硬件的 logcat 输出:

就是这样。如果有人知道如何解释这一点，请告诉我。

谢谢!

Answer 1

我刚遇到同样的问题。当 rsDebug 位于同一函数的某处时，它似乎已修复。这为我修好了:

if(x > 0) {
    if(x < 0) {
        rsDebug("Workaround for renderscript bug", 0.0f);
    }

    /* Code */
}

使用它，rsDebug 从未真正被调用，所以它不会输出任何东西。

注意这不起作用:

if(0) {
    rsDebug("Workaround for renderscript bug", 0.0f);
}

这可能被优化掉了。
