Android Shared Preferences Helper

Android Library to handle SharedPreferences boilerplate code and other tools

Download

dependencies {
  compile 'com.github.seanzor:shared-preferences-helper:1.1.0'
}

Usage

Define the preferences keys in a resource file:

<resources>
    <string name="pref_number_of_runs">pref_number_of_runs</string>
</resources>

And use them:

// As in most cases, create a default shared preference
final SharedPreferences defaultSharedPreferences = PreferenceManager.getDefaultSharedPreferences(this);

// Create the helper which will wrap the SharedPreferences we just created
mPref = new SharedPrefHelper(getResources(), defaultSharedPreferences);

// Sample for number of times the app ran, deafult of 0
int numberOfTimesRan = mPref.getInt(R.string.pref_number_of_runs, 0);
numberOfTimesRan++;

// Now apply the change to be persistent
mPref.applyInt(R.string.pref_number_of_runs, numberOfTimesRan);

// Display the result
((TextView)findViewById(R.id.activityMainResultField)).setText(
        String.valueOf(numberOfTimesRan));
