How to check if SharedPreferences exists or not

android, sharedpreferences

Solution

`SharedPreferences` has a `contains(String key)` method, which can be used to check if an entry with the given key exists.

Problem

I'm checking in this way if the file exists, but I need to go beyond, I need to know if there is one in specific, is there any way? ``` File f = new File("/data/data/com.eventrid.scanner/shared_prefs/Eventrid.xml"); if (f.exists()){ } else{ } ```
