Gradle Dependency (jcenter)

Release is in process...

buildscript {
    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
    }
}

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

dependencies {
    compile 'com.thefinestartist:utils:0.9.5'
    apt 'com.thefinestartist:compilers:0.9.5'
}

Initialization (Application)

Call Base.initialize(context) within your Application onCreate() method.

public class App extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        Base.initialize(this);
    }
}

intent.putExtra(YourActivity.EXTRA_TITLE, "Activity title");
intent.putExtra("ids", new ArrayList<Integer>());
startActivity(intent);

public class YourActivity extends AppCompatActivity {

    public static final String EXTRA_TITLE = "TITLE";

    @Extra(EXTRA_TITLE) String title;
    @Extra ArrayList<Integer> ids;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ExtrasBinder.bind(this);
        // do something...
    }
}

// Show YourFragment with extras
YourFragment fragment = new YourFragment();
Bundle bundle = new Bundle();
bundle.putString("Name", "Fragment name");
fragment.setArguments(bundle);

public class YourFragment extends Fragment {

    @Extra("NAME") String name;
    
    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        ExtrasBinder.bind(this);
        // do something...
    }
}
