男儿欲遂平生志，六经勤向窗前读。这篇文章主要讲述RenderScript在Android 6上崩溃相关的知识，希望能为你提供帮助。
我使用RenderScript建立了一个应用程序，在大多数手机上都能正常工作，但在fi.模拟器上用API 21初始化时就崩溃了。我已经最小化了我的renderscript代码，看看什么时候它仍然崩溃。它发生在macOS Catalina和Ubuntu 19.10上。
这可以编译。
#pragma version(1)
#pragma rs java_package_name(com.me.my-obfuscated_package-name);
rs_allocation myFirstAlloc;
但在第二行就崩溃了
private val renderScript = RenderScript.create(context)
private val scriptTest = ScriptC_test(renderScript)
【RenderScript在Android 6上崩溃】在这一行
ScriptC.java:/**
* Only intended for use by the generated derived classes.
*
* @param rs
*/
protected ScriptC(RenderScript rs, String resName, byte[] bitcode32, byte[] bitcode64) {
super(0, rs);
long id = 0;
if (RenderScript.sPointerSize == 4) {
id = internalStringCreate(rs, resName, bitcode32);
} else {
id = internalStringCreate(rs, resName, bitcode64);

}
if (id == 0) {
throw new RSRuntimeException("Loading of ScriptC script failed.");
}
setID(id);
}

我哪里出错了？
答案很明显。
rs_allocation 和任何关系函数都被添加到API 22中。我将设置 renderscriptSupportModeEnabled 为真，未来我会使用动态特性来大幅降低API 22+的大小。推荐阅读
