Is it possible to stop a JNI call

Question

I developed a c library. I call The c functions of the library from my JAVA code with JNI :

jstring Java_com_example_openafreerdp_UnboundedService_invokeNativeFunction(JNIEnv* env, jobject obj) {
    ...
}

The JNI function is called from java in this way:

public class UnboundedService extends Service {

    static {
        System.loadLibrary("hellondk");
    }
    private native String invokeNativeFunction();

    private class JniBackGround extends AsyncTask<String, String, String> {
        @Override
        protected String doInBackground(String... ss) {
            final String str = invokeNativeFunction();          
            return str;
        }
    }
    ...
    @Override
    public void onStart(Intent intent, int startId) {
        JniBackGround task = new JniBackGround();
        task.execute(new String[] { "http://www.any.com" });
    }
}

Now my C function take long time to fulfill execution. And I want to Add a button to stop this execution. How I can stop it with JAVA?

如果fx有某种inf循环，则while(true)他可以始终使用while(someFlag)并在此新的invokeNativeStopFunction内部将someFlag设置为false ...如果他使用的是curl库调用（我怀疑，因为url是（不传递给本机）他可以在那里取消卷曲请求……等等，等等……– Selvin
