Import the Problems and Solutions of the myeclipse project.

1. If @ Override is added to the myeclipse method, an error is returned.

The following error is reported in the @ Override method:

The method oncreate (Bundle) of type HelloWorld must override or implement a supertype method

Override refers to the description that the subclass inherits the methods in the parent class.

Override is already available in JDK 5, but there is a Bug that does not support the implementation of the interface. I think this is not Override, and JDK 6 fixes this Bug, you can add @ Override to both the method Override of the parent class and the implementation of the interface.

 

Modify the compiler version specified by myeclipse in the java compiler option to change the compiler method in myEclipse at least 1.6 or later: project-> Properties-> Java Compiler-> Configure Workspace Setting, which can be set on the pop-up page.
