findFragmentById() returns an existing instance (or null, if there is no instance found with the given ID).

By using the new keyword, a new instance is created.

You should create fragment by static factory method and pass arguments in Bundle. As stated above, .findFragmentById(id) finds fragment, placed in layout container with given Id. there is another method .findFragmentByTag(String tag), where string is ay user- defined string. The latter is more handy.
