Add a new Class Activity to your Android Project

1. Create an Android project, if you don't already have one.

2. Create a new file in the src\com\ directory of your app named MyNewClass.java
Example: If your package is named com.akp.myandroidapp, then the directory would be src\com\akp\myandroidapp\MyNewClass.java

3. In the MyNewClass.java, copy the below contents to the file and save. This will create a new class.

package com.akp.myandroidapp;

public class MyNewClass {
}

4. Compile and run!
