A small Android library to manage one-off operations.
Some things should happen once.
- Users should only get the guided tour once.
- Release notes should only pop up once every app upgrade.
- Your app should only phone home to update content once every hour.
Once
provides a simple API to track whether or not your app has already performed an action within a given scope.
First things first, you'll need to initialise Once on start up. In your Application
class's onCreate()
override add the follow:
Once.initialise(this);
Now you're ready to go. Say you wanted to navigate to a 'WhatsNew' Activity every time your app is upgraded:
String showWhatsNew = "showWhatsNewTag";
if (!beenDone(THIS_APP_VERSION, showWhatsNew)) {
startActivity(this, WhatsNewActivity.class);
markDone(showWhatsNew);
}
Add a library dependency to your app module's build.gradle
:
dependencies {
compile 'com.jonathanfinerty.once:once:0.3.1'
}
You'll need to have jcenter()
in your list of repositories
Have a look at the example app in once-example/
for more simple usage.
