如何在我的Android应用程序项目中包括一个新的.java文件？

Question

I'm sorry, I'm a newbie, and I think that's simple, but I'm discovering the coding with Eclipse so I have this simple question : How to include a new .java file in my Android project ?

My words are perhaps inapropriates, and to be more clear, I'm creating an Android application, and I want to include a .java file (located in projectname/src/ )

Actually I have an unique file, MainActivity.java , and my application start fine. I want to include a timer in my application, so I created a new Timer.java file in same folder, but when I start my app, it contain only data from this MainActivity.java file, nothing about my Timer.jar file.

So how I must declare the new file in my project ?

Answer 1

you simply add it by right clicking on your src folder

you need to declare it on your AndroidManifest.xml file

    <activity
        android:name=".Timer"
        android:label="@string/title_timer" >
    </activity>
