Finally, save your changes with one of the appropriate methods!

SharedPreferences mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);

SharedPreferences.Editor editor = mSharedPreferences.edit().putInt("MeaningOfLife", 42).commit();

not sure what is wrong with my code, help please!

CodeChallenge.java 
SharedPreferences mSharedPreferences = PreferenceManager.getDefaultSharedPreferences(context);

SharedPreferences.Editor editor = mSharedPreferences.edit().putInt("MeaningOfLife", 42).commit();

When you chain methods like that the value returned is what the end of the chain returns. According to the Android docs commit() returns a boolean, not a SharedPreferences.Editor. Instead you should split it into 2 lines. 

SharedPreferences.Editor editor = mSharedPreferences.edit();
editor.putInt("MeaningOfLife", 42).commit();
