How to resolve it?

This issue occurs because the "lib" folder is renamed to "libs" now by Android People.
And as soon as we place our external jars to this "libs" folder then it will automatically be added to the build path of the application.

This happens when the build library classes conflict with those at run-time. Try performing a Clean of your project followed by a build.

That can be the result when you have compiled against a different library than you are using at runtime.
A good explanation can be had here.
Another possibility is having a duplicate class in the classpath somewhere, such as in a library jar.

Does any one have a solution for this??
This is a problem with your code, you can't use an object that is null. This is a hint.

NetworkConnectivityListener class not found on UPC300-2.2 Viewsonic G-Tablet

I am getting this error in my application, and this happens only on UPC300-2.2 Viewsonic G-Tablet. All answers I've found so far (including this one) adviced on putting
<uses-permission android:name="android.permission.INTERNET"/>
to the manifest file, but it doesn't help.

If that is TRUE, you can grab the source code of the class from the Android Source and add it yourself
