Motivation

AsyncService is born from an article I wrote a few weeks ago, which gave me a lot of feedbacks and interesting comments. AsyncService manages threading and caching transparently in your Android app. It's an alternative to AsyncTasks, Loaders, or more advanced libs like RxJava, Robospice, Groundy,… but AsyncService focuses on keeping your code short and simple!

Sample

Write your asynchronous service...

@AsyncService
public class DemoService {

    public User getUser(String name) {
        // Runs asynchronously.
        return …;
    }

}

... then use it.

… {
    service.getUser("joan");
}

@OnMessage void onUser(User e) {
    // Runs on UI thread.
}

Where to find it

AsyncService is hosted on Maven Central, just add this line to your gradle dependencies:

compile('com.joanzapata.android.asyncservice:android-asyncservice:0.0.5@aar') { transitive = true }

{ transitive = true } is required at the time of the writing because the android-plugin doesn't look for AAR transitive dependencies by default.

Proguard

In case you use Proguard, you'll have to add these entries to your configuration file.

-dontwarn com.joanzapata.android.asyncservice.**
-keep @com.joanzapata.android.asyncservice.api.annotation.AsyncService class *
-keep class **Injector
-keepnames class **Injector
-keepnames class * {
    @com.joanzapata.android.asyncservice.api.annotation.InjectService *;
}
-keepnames class * {
    @com.joanzapata.android.asyncservice.api.annotation.OnMessage *;
}
-keep class com.esotericsoftware.kryo.** {*;}
