Typed Preferences

This library for Android provides classes which allow to store and retrieve settings from the preferences. There is an individual class for each native type:

Each class comes with two constructors - one of them allows to ommit the default value.

All classes declare the same methods: get(), isSet(), set() and delete(). Here are the method signatures as definied in the StringPreference class.

public class StringPreference {
    public String get() { ... }
    public boolean isSet() { ... }
    public void set(String value) { ... }
    public void delete() { ... }
}

Wrappers for frequently used classes can be found and added in the wiki. Take a look!

How to get the thing running?

Add the library as a dependency to your build.gradle in case you use Gradle:

dependencies {
    compile "info.metadude.android:typed-preferences:{$version}"
}

Or if you use Maven you should be looking for this:

<dependency>
    <groupId>info.metadude.android</groupId>
    <artifactId>typed-preferences</artifactId>
    <version>{$version}</version>
</dependency>

For anything else, go to Maven Central - or just build the library yourself.

Minimum SDK version / API level

The library is available in two different versions. If you need to support API level 8 in your project you must include the latest 1.x.x version. This library version persists the settings synchronously using the commit method of the SharedPreferences.Editor. If the minimum SDK version you need to support is API level 9 you can choose the latest 2.x.x version which relies on the apply method of the SharedPreferences.Editor. Thereby settings are persisted asynchronously.

For further information please stick to documentation of the SharedPreferences.Editor interface.

Demo project

Check out the demo project TypedPreferencesDemo which shows how to use the library.

Tests

Run ./gradlew clean test to execute the tests.
