IntentBuilder

Type safe intent building for services and activities.

IntentBuilder is a type safe way of creating intents and populating them with extras. Intents were created to be very dynamic but often times the dynamic nature of intents is not needed and just gets in the way of writing safe code.

Installation

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.4'
    }
}

apply plugin: 'com.neenbedankt.android-apt'

dependencies {
    compile 'se.emilsjolander:intentbuilder-api:0.14.0'
    apt 'se.emilsjolander:intentbuilder-compiler:0.14.0'
}

Usage

Annotate your activities and services with an @IntentBuilder annotation so that they are picked up by the library. For every class with an @IntentBuilder annotation a class named MyActivityIntentBuilder will be generated (Replace 'MyActivity' in the class name whith whatever the name of your Activity or Service class is). If your activity or service takes in parameters via extras in the intent you can now mark field with the @Extra annotation and they can be injected with the static inject method on the generated intent builder class. Extras can be marked as optional with the @Nullable annotation.

Sample activity using IntentBuilder:

@IntentBuilder
class DetailActivity extends Activity {

    @Extra
    String id;

    @Extra @Nullable
    String title;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        DetailActivityIntentBuilder.inject(getIntent(), this);
        // TODO use id and title
    }

startActivity(new DetailActivityIntentBuilder("12345")
    .title("MyTitle")
    .build(context))
}

Sample service using IntentBuilder:

@IntentBuilder
class DownloadService extends IntentService {

    @Extra
    String downloadUrl;

    @Override
    protected void onHandleIntent(Intent intent) {
        MyServiceIntentBuilder.inject(intent, this);
    }

}

startService(new DownloadServiceIntentBuilder("http://google.com").build(context))
