Android中的sun.misc.Unsafe替代品

Question

我知道sun.misc.Unsafe（从我所理解的可用于write directly on memory in java）仅部分在Android（dammit）上实现，但我正在移植Apache Flink在Android上，有很多这样的指令：

private static sun.misc.Unsafe getUnsafe() {
    try {
        Field unsafeField = sun.misc.Unsafe.class.getDeclaredField("theUnsafe");
        unsafeField.setAccessible(true);
        return (sun.misc.Unsafe) unsafeField.get(null);
    } catch (SecurityException e) {
        throw new RuntimeException("Could not access the sun.misc.Unsafe handle, permission denied by security manager.", e);
    } catch (NoSuchFieldException e) {
        throw new RuntimeException("The static handle field in sun.misc.Unsafe was not found.");
    } catch (IllegalArgumentException e) {
        throw new RuntimeException("Bug: Illegal argument reflection access for static field.", e);
    } catch (IllegalAccessException e) {
        throw new RuntimeException("Access to sun.misc.Unsafe is forbidden by the runtime.", e);
    } catch (Throwable t) {
        throw new RuntimeException("Unclassified error while trying to access the sun.misc.Unsafe handle.", t);
    }
}

在编译时生成错误。

所以我的问题是：Android上有相同目的的替代方案吗？
