现象: ... java: 1801: method does not override a method from its superclass @Override...
原因: Eclipse is defaulting to Java 1.5 and you have classes implementing interface methods (which in Java 1.6 can be annotated with @Override, but in Java 1.5 can only be applied to methods overriding a superclass method).
解决方案: Go to your project/ide preferences and set the java compiler level to 1.6 and also make sure you select JRE 1.6 to execute your program from eclipse. java的编译器是1.6版本的,选择编译级别为1.6,但重要的一点是,选择build的android库是1.5的即可,生成的apk程序是可以在1.5内核上跑起来。
