从Method类中获取注释字段

Question

I'm trying to fetch the annotations field from Method class in Android Sdk 19 and jdk 1.7. But the code below is throwing NoSuchFieldException. But I could find the exact field in Method.java file.

Field field = Method.class.getDeclaredField("annotations");

You can't read the field cause it's private , in order to get around it you have to make it accessible first:

    Field f = Method.class.getDeclaredField("annotations"); 
    f.setAccessible(true);
    System.out.println("f = " + f);
