Your imports are probably wrong in ProducDetailsTopFragment. Make sure you are using android.support.v4.app.Fragment

You're problem seems to be here:

12-31 18:14:41.201: E/AndroidRuntime(13699): Caused by: java.lang.ClassCastException: com.lenovo.bsharp.ProductDetailsTopFragment cannot be cast to android.support.v4.app.Fragment

Make sure your ProductDetailsTopFragment class is extending android.support.v4.app.Fragment and not Fragment.

Or you can post the entire code for ProductDetailsTopFragment so we can see if that's the issue or not.
