This library intended to simplify the work with action handling in android projects. Just collect actions in a handler and bind them to views.

Add library as gradle dependency

repositories {

 dependencies {

  compile 'com.drextended.actionhandler:actionhandler:1.2.0' 


  • .IntentAction - Action with Intent: start activity, satrt service, send broadcast.
  • .DialogAction - Aaction which shows simple dialog before it fired.
  • .RequestAction - Simple action which makes network request.
  • .RxRequestAction - Simple action which makes network requests with RxJava observable calls.
  • .CompositeAction - Composite action which can contain other actions inside and shows simple menu to choose one of them when fired.
  • Any custom actions...


 mActionHandler = new ActionHandler.Builder()

  .addAction(null, new SimpleAnimationAction()) // Applied for any actionType

  .addAction(null, new TrackAction()) // Applied for any actionType

  .addAction(ActionType.OPEN_NEW_SCREEN, new OpenSecondActivity())

  .addAction(ActionType.FIRE_ACTION, new ShowToastAction())

  .addAction(ActionType.FIRE_DIALOG_ACTION, DialogAction.wrap(getString(R.string.action_dialog_message), new ShowToastAction()))

  .addAction(ActionType.FIRE_REQUEST_ACTION, new SampleRequestAction())


 new CompositeAction<String>(new CompositeAction.TitleProvider<String>() {


  public String getTitle(Context context, String model) {

return "Title (" + model + ")";



new ActionItem(ActionType.OPEN_NEW_SCREEN, new OpenSecondActivity(), R.string.menu_item_1),

new ActionItem(ActionType.FIRE_ACTION, new ShowToastAction(), R.drawable.icon, R.color.tint, R.string.menu_item_2),







  // and then on view click
  mActionHandler.onActionClick(view, ActionType.OPEN_NEW_SCREEN, getSampleModel());

with Data Binding


<layout ...>







<FrameLayout ...






<!-- modelLongClick is optional, will be used model if null -->

<!-- Other Views -->
  </FrameLayout>  </layout>

Note: RequestAction and RxRequestAction can show simple progress dialog. By default they use ProgressBarController, which should be initialized with Application instance to avoid WindowLeaked Errors.

public class Application extends {

  public void onCreate() {





// Somewhere before first usage ProgressBarController.init((Application) getApplicationContext());

Composer is a modern reactive replacement for square/spoon with following feature set:

  • Parallel test execution on multiple emulators/devices with test sharding support.
  • Logcat output capturing per test and for whole test run as well.
  • Screenshots and files pulling for each test reactively (with support for square/spoon folder structure).
  • JUnit4 report generation.

A playlist file (*.pls) parser library for Android.

An android widget library to show GPS status and signal strength.

An Android Library with demo application, to send media and text messages via Whatsapp on rooted device.

An example project for creating machine learning model for MNIST to detect hand written digits.

The library is a RecyclerView-based implementation of a scrollable list, where current item is centered and can be changed using swipes. It is similar to a ViewPager, but you can painlessly create layout, where views adjacent to the currently selected view are partially or fully visible on the screen.

The library uses a custom LayoutManager to adjust items' positions on the screen and handle scroll, so view reordering operations use the full power of RecyclerView API and are extremely efficient.
