I want to add a basic snackbar to my application but i have received an error that i couldn't figure out why.
I added this code in the onCreateView() method in my Fragment.
Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
And received this error:
06-01 10:26:09.955 1232-1232/? E/ActivityThread﹕ Failed to find provider info for me.muraterdogan.watchme.MetricaContentProvider

If your Fragment is added to existing activity(Remember you can add it through xml), you should call the SnackBar's method into the onActivityCreated() method of the Fragment.
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Snackbar.make(view, "Snackbar", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
