Show a beautiful Intro to your users with ease.

You can download the latest sample app here.

Table of contents

Include in your Project

Add this to your root build.gradle (usually in the root of your project):

repositories {
    maven { url "" }

And this to your module build.gradle (usually in the app directory):

dependencies {
    implementation 'com.github.rubengees:introduction:2.0.0'

If that doesn't work, look if there is a new version and the Readme was not updated yet.

If you want to use asynchronous image loading, introduced in the new version 1.1.0, you will need Glide or some other image loading library. If you want to use GIFs you will also need it.


Create an IntroductionBuilder like the following:

new IntroductionBuilder(this) // this is the Activity you want to start from.

Then add some Slides to your Introduction:

new IntroductionBuilder(this).withSlides(generateSlides())
private List<Slide> generateSlides() {
    List<Slide> result = new ArrayList<>();

    result.add(new Slide()
            .withTitle("Some title")
            .withDescription("Some description")

    result.add(new Slide()
            .withTitle("Another title")
            .withDescription("Another description")

    return result;

Finally introduce yourself!

new IntroductionBuilder(this).withSlides(generateSlides()).introduceMyself();

That was easy right?

You can do many customizations, which will be covered by the following.


You can let the user make decisions, which you can use like settings. To do that you add an Option to your slide:

new Slide().withTitle("Feature is doing something")
          .withOption(new Option("Enable the feature"))

When the user completes the intro, you will receive the selected Options in onActivityResult. To read the result:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
     if (requestCode == IntroductionBuilder.INTRODUCTION_REQUEST_CODE && resultCode == RESULT_OK) {
         String result = "User chose: ";

         for (Option option : data.<Option>getParcelableArrayListExtra(IntroductionActivity.OPTION_RESULT)) {
            result += option.getPosition() + (option.isActivated() ? " enabled" : " disabled");

The constant value of the request is 32142, so don't use that yourself. It is possible that the user cancels the intro. If that happens, the resultCode is RESULT_CANCELLED and no Options are passed back.

Use Gifs as images

This library supports GIFs. You need to load them asynchronously as the loading may take a while:

new IntroductionBuilder(this)
        .withOnSlideListener(new OnSlideListener() {
            public void onSlideInit(int position, @Nullable TextView title, @NonNull ImageView image,
                                    @Nullable TextView description) {
                if (position == 1) { // Assume we want to load the GIF at Slide 2 (index 1).

This will add the GIF, which will be automatically played when the users navigates to the Slide.

Runtime Permissions

Android Marshmallow introduced Runtime Permissions, which can be requested easily with this lib. To do that, you can add a global listener like the following:

new IntroductionBuilder(this)
        .withOnSlideListener(new OnSlideListener() {
            public void onSlideChanged(int from, int to) {
                if (from == 0 && to == 1) {
                    if (ActivityCompat.checkSelfPermission(MainActivity.this,
                            Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                                new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 12);

You can check if the permissions were granted like the following:

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,
                                       @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (requestCode == 12) {
        if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            Toast.makeText(this, "Permission was successfully granted!", Toast.LENGTH_LONG).show();

You can use that listener for different things too, of course!


There are two available styles: Translucent and Fullscreen. To apply one of those styles, do the following:

new IntroductionBuilder(this)
                .withStyle(new FullscreenStyle())

Translucent is the default style.

Custom Views

You can supply your own View to a Slide instead of just setting the title, image and description.
This is done like follows:

Create a class which implements CustomViewBuilder:

public class CustomViewBuilderImpl implements Slide.CustomViewBuilder {

    public View buildView(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) {
        return inflater.inflate(R.layout.layout_custom, parent, false);

Then set it to your Slide:

new IntroductionBuilder(this)
        .withSlides(new Slide()
                .withCustomViewBuilder(new CustomViewBuilderImpl())

If you set a CustomViewBuilder to your Slide, all other values aside from the color are overridden. You have to manage all on your own.

Upgrade Guide

1.4.0+ to 2.0.0+

  • This library now requires Java 8 (available in the new Android Studio 3 toolchain).
  • Behaviour change: Not passing a title, description or option hides the respective views. This way you can show fullscreen images.
    • The title and description parameters of the onSlideInit callback are now @Nullable
  • CustomViewBuilder is now in a different package and has been converted into an interface.

1.3.9 to 1.4.0+

  • Slide and Option have been moved into a different package. Just let Android Studio re-import them.
  • The OnSlideListener is now an interface on its own. Remove IntroductionConfig before each and let Android Studio re-import. Furthermore @NotNull annotations have been added; You should add them to the signature.

1.1.0 to 1.1.1+

  • The OnSlideInit method in the OnSlideListener now comes without the Fragment context. If you need a Context, call image.getContext().
  • There is now a class for Styles instead of an Integer. If you apply no Style, you have to do nothing, if you use one, change it to the following e.g.: .withStyle(new FullscreenStyle()).

1.0.x to 1.1.0+

  • The OnSlideChangedListener was renamed to OnSlideListener. Just rename it and it's working again.
  • Asynchronous image loading is now available (and recommended!). See the Use GIFs as drawables section for more info. It applies for all types of images. GIFs won't work without asynchronous loading from now on!
