I have project in my eclipse where I have used multiple packages with the same prefix for all the packages. Here is a screenshot of the structure!

Eclipse IDE screenshot

The problem is, that when I run the application I get this error message:

Unable to start activity ComponentInfo{com.td.bookshelf/com.td.bookshelf.SplashActivity}: java.lang.NullPointerException)

I have added all the packages manually and copied the class files from the other project.
So I clean built the project and also restarted the eclipse but in vain.

Please help me to get rid of the error.

    It looks like the error is not coming from your package structure.

    In the stack trace you can read : 

    E/AndroidRuntime(4900): Caused by: java.lang.NullPointerException
E/AndroidRuntime(4900):     at com.td.bookshelf.SplashActivity.onCreate(SplashActivity.java:56)

    You’re getting a NullPointerException when the onCreate method of the SplashActivity is called.

    There’s probably something wrong in your onCreate method.
