RenderScript：一个ScriptC_XXXX无法创建两次？

Question

这是我的类RSBaseFilterEngine的构造函数，并且我的程序将在不同的活动中创建该类的许多实例。

public RSBaseFilterEngine(Context context) {
    rs = RenderScript.create(context);
    this.context = context;
    script = new ScriptC_BaseFilter(rs);
}

问题是，如果我收到此类的指令超过1次，程序将崩溃。 处理程序时将发生崩溃

script = new ScriptC_BaseFilter(rs);

并且，错误日志是

Caused by: android.support.v8.renderscript.RSRuntimeException: Loading of ScriptC script failed.
at android.support.v8.renderscript.ScriptC.<init>(ScriptC.java:69)
at com.xxxxxxxxxxx.xxxxxxxx.algorithms.filter.ScriptC_BaseFilter.<init>(ScriptC_BaseFilter.java:41)
at com.xxxxxxxxxxx.xxxxxxxx.algorithms.filter.ScriptC_BaseFilter.<init>(ScriptC_BaseFilter.java:35)
at com.xxxxxxxxxxx.xxxxxxxx.algorithms.RSBaseFilterEngine.<init>(RSBaseFilterEngine.java:33)

为什么无法两次创建ScriptC_BaseFilter？ 然后，我改变了这样的代码

public RSBaseFilterEngine(Context context) {
    rs = RenderScript.create(context);
    this.context = context;
    script = new ScriptC_BaseFilter(rs);
    script.destroy();
    script = new ScriptC_BaseFilter(rs);
}

如我所料，当程序第一次调用此构造函数时，它崩溃了。

那么，谁能告诉我为什么这样做会增强呢？ 是否有一些我不注意的细节？谢谢。

好吧，我将发布整个logcat

我将发布我最近进行的一些测试。

以下代码段将使程序崩溃，其共同点是它们尝试两次创建相同的脚本：

rs = RenderScript.create(context);
script = new ScriptC_BaseFilter(rs);
rs.destroy(); // same problem occurred after changed this line to rs.finish() 
rs = RenderScript.create(context);
script = new ScriptC_BaseFilter(rs);

// create same script using different renderscript context will not help
// do rs and rs_base use the same context?
rs = RenderScript.create(context);
rs_base = RenderScript.create(context);
script = new ScriptC_BaseFilter(rs);
script_base = new ScriptC_BaseFilter(rs_base);

Answer 1

您可以检查以下内容吗？ rs.finish刷新renderscript中所有未完成的命令

rs = RenderScript.create(context);
this.context = context;
script = new ScriptC_BaseFilter(rs);
script.destroy();
rs.finish(); //ADD THIS LINE IN YOUR CODE 
script = new ScriptC_BaseFilter(rs);

Answer 2

我的同事找到了解决此问题的解决方案。

首先，您应确保这些代码必须添加到文件“ project.properties”中

#------ RenderScript Configuration -------
renderscript.target=18

renderscript.support.mode=true

sdk.buildtools=18.1.0

#------ RenderScript Configuration -------

然后，用更大的文件替换sdk / build-tools / 18.1.0中的文件“ libbcc.dll”（原始文件的大小小于1M，正确的文件为5.1M）。

Answer 3

com.xxxxxxxxxxx.xxxxxxxx.algorithms.demo是您放入.rs文件编译指示中的项目的实际名称吗？ 这必须完全匹配，否则您将无法加载.bc / .so文件。
