DaggerAutoInject
Inject automatically your Activities & Fragments, just with a simple annotation
@InjectActivity
public class MainActivity extends AppCompatActivity {
@Inject
SharedPreferences sharedPreferences;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
protected void onStart() {
super.onStart();
sharedPreferences.edit()
.putString("androidVerions", "O")
.apply();
}
}Download
In your module
def dagger_version = "2.11-rc2"
dependencies {
compile 'com.github.florent37:dagger-auto-inject:1.0.0'
annotationProcessor 'com.github.florent37:dagger-auto-inject-compiler:1.0.0'
//dagger2
compile "com.google.dagger:dagger:$dagger_version"
compile "com.google.dagger:dagger-android:$dagger_version"
compile "com.google.dagger:dagger-android-support:$dagger_version"
annotationProcessor "com.google.dagger:dagger-android-processor:$dagger_version"
annotationProcessor "com.google.dagger:dagger-compiler:$dagger_version"
}Component
Just add generated ActivityModule.class and FragmentModule.class into your Dagger's component
@Singleton
@Component(modules = {
AppModule.class,
AndroidInjectionModule.class,
AndroidSupportInjectionModule.class,
ActivityModule.class,
FragmentModule.class,
})
public interface AppComponent {
void inject(MainApplication application);
@Component.Builder
interface Builder {
@BindsInstance
Builder application(Application application);
AppComponent build();
}
}Setup Application
Just annotate your application with @InjectApplication givin your Component, then call DaggerAutoInject.init(this);
Don't forget to implement HasActivityInjector as follow
@InjectApplication(component = AppComponent.class)
public class MainApplication extends Application implements HasActivityInjector {
@Inject
DispatchingAndroidInjector<Activity> activityAndroidInjector;
@Override
public void onCreate() {
super.onCreate();
final AppComponent appComponent = DaggerAppComponent.builder()
.application(this)
.build();
DaggerAutoInject.init(this, appComponent);
}
@Override
public AndroidInjector<Activity> activityInjector() {
return activityAndroidInjector;
}
}Inject Fragment
Just add @InjectFragment to your fragment
@InjectFragment
public class MainFragment extends Fragment {
@Inject
SharedPreferences sharedPreferences;
public static MainFragment newInstance() {
return new MainFragment();
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_main, container, false);
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
System.out.println(sharedPreferences.getAll());
}
}Then in your Activity / BaseActivity, implements HasSupportFragmentInjector
public class BaseActivity extends AppCompatActivity implements HasSupportFragmentInjector {
@Inject
DispatchingAndroidInjector<Fragment> dispatchingFragmentInjector;
@Override
public AndroidInjector<Fragment> supportFragmentInjector() {
return dispatchingFragmentInjector;
}
