How to catch UnsatisifiedLinkError when using NDK-built library in an Android app?

Question

I have an Android project that contains a class that uses JNI to pull a value from a C function. The C function was built into a library using NDK. The value returned from the C function is in turn used to initialize a variable inside a class when its first loaded. This works fine. However, I also want it to work when the library is missing by providing a default value. So Im using something like this:

static native String getstring();

static {
        try {
                System.loadLibrary("library");
                NAME = getstring();
        }
        catch (Exception e) {
                NAME = "Default";
        }
}

尽管有这个问题,但当我尝试运行此代码并且缺少库时,我仍然得到一个UnsatisfiedLinkError.为什么我没有抓住异常？我究竟做错了什么？

UnsatisfiedLinkError不是的子类Exception.层次结构UnsatisfiedLinkError是:

Throwable->Error->UnsatisfiedLinkError

UnsatisfiedLinkError如果你想处理它,你最好抓住它.
