Use a Bundle. Here's an example:

Fragment fragment = new Fragment();Bundle bundle = new Bundle();bundle.putInt(key, value);fragment.setArguments(bundle);

Bundle has put methods for lots of data types. Seehttp://developer.android.com/reference/android/os/Bundle.html

Then in your Fragment, retrieve the data (e.g. in onCreate()) with:

Bundle bundle = this.getArguments();int myInt = bundle.getInt(key, defaultValue);

getArguments() is returning null because "Its doesn't get anything"

Try this code to handle this situation

if(getArguments()!=null){int myInt = getArguments().getInt(key, defaultValue);}
