An URL router supporting AOP, stack control, cross-page message, and dynamic routing.

Get sample on Google Play

Getting started

In your build.gradle:

dependencies {
    compile 'me.drakeet.floo:floo:1.1.0'
}

If you are using com.android.tools.build:gradle:3.+, use this instead:

dependencies {
    implementation 'me.drakeet.floo:floo:1.1.0'
}

Usage & Examples

public class App extends Application {

    @Override
    public void onCreate() {
        super.onCreate();

        Map<String, Target> mappings = new HashMap<>();
        mappings.put("m.drakeet.me/home", new Target("floo://drakeet.sdk/target"));
        mappings.put("m.drakeet.me/link", new Target("floo://drakeet.sdk/target"));
        mappings.put("m.drakeet.me/web", new Target("floo://drakeet.sdk/web"));
        mappings.put("m.drakeet.me/container", new Target("floo://m.drakeet.me/container"));

        Floo.configuration()
            .setDebugEnabled(BuildConfig.DEBUG)
            .setIntentHandler(new FragmentIntentHandler()) // DefaultIntentHandler by default 
            .addRequestInterceptor(new LogInterceptor("Request"))
            .addTargetInterceptor(new LogInterceptor("Target"))
            .addTargetNotFoundHandler(new WebHandler())
            .addTargetNotFoundHandler(new OpenDirectlyHandler())
            .addTargetNotFoundHandler(new TargetNotFoundToaster());

        Floo.apply(mappings);
    }
}
Floo.navigation(this, "sdk://m.drakeet.me/home")
    .appendQueryParameter("date", "2017.9.11")
    .appendQueryParameter("user_id", "drakeet")
    .putExtra(TargetActivity.KEY_MAIL, mail)
    .start();
// Allow incomplete URLs
Floo.navigation(this, "PureWriter").start();
Floo.stack(this)
    .target(Urls.indexUrl("https://chunchun.io/page2"))
    .result("abc")
    .start();
Floo.stack(this)
    .popCount(2)
    .result(anything)
    .start();
Floo.stack(this).popCount(3).start();

Principle

For example, if we call the following code:

Floo.navigation(context, "https://play.google.com/store/apps/details")
    .appendQueryParameter("id", "com.drakeet.purewriter")
    .start();

At the beginning, Floo will build the URL and parameters to a full URL, like as: https://play.google.com/store/apps/details?id=com.drakeet.purewriter, and ask your registered RequestInterceptors: "Do you want to intercept and handle the URL?"

Every your registered RequestInterceptor will receive the full URL one by one. If someone deals with it and returns true, the link ends.

Otherwise, Floo will use the authority(host:port) + path to get an index key. For this example, it is play.google.com + /store/apps/details -> play.google.com/store/apps/details.

Then, Floo uses the index key to find a registered target URL / URI. If Floo finds it, Floo will transfer or merge the parameters of the original URL to the new URL. Otherwise, Floo will create a TargetNotFound event, and dispatch it to all of your registered TargetNotFoundHandlers one by one. If someone deals with it and returns true, the link ends. If nobody deals with it, the link also ends.

So what if Floo finds a target and generates a new URL?

At this point, Floo will send the new URL one by one to your registered TargetInterceptors. If someone deals with it and returns true, the link ends.

Otherwise, Floo comes to the last step, it will use this new URL to create an Intent, and start the Intent. This new URL may be associated with an Activity, so the Activity will be opened.
