Easy SharedPreference Engine foR ANDROid

What?

esperandro makes it simple to use SharedPreferences in a nicer and less error-prone way.

Without esperandro a key is referenced by a string:

• String myPreference = preferences.getString("myPreference", "default value") // load preference
• preferences.edit().putString("myPreference", myPreference).commit() // store preference

With esperandro you adhere to an interface that you defined:

@SharedPreferences
interface MyPreferences {
    String getMyPreference();
    void setMyPreference(String myPreference);
}

• String myPreference = preferences.getMyPreference() // load preference
• preferences.setMyPreference(myPreference) // store preference

Type safe, easy, less error-prone.
