Sample App:

AppIntro

AppIntro is an Android Library that helps you make a cool intro for your app, like the ones in Google apps.

##How to use Add this to your build.gradle:

repositories {
    mavenCentral()
}

dependencies {
  compile 'com.github.paolorotolo:appintro:3.4.0'
}

Create a new Activity that extends AppIntro:

public class MyIntro extends AppIntro {

    // Please DO NOT override onCreate. Use init.
    @Override
    public void init(Bundle savedInstanceState) {

        // Add your slide's fragments here.
        // AppIntro will automatically generate the dots indicator and buttons.
        addSlide(first_fragment);
        addSlide(second_fragment);
        addSlide(third_fragment);
        addSlide(fourth_fragment);
        
        // Instead of fragments, you can also use our default slide
        // Just set a title, description, background and image. AppIntro will do the rest.
        addSlide(AppIntroFragment.newInstance(title, description, image, background_colour));

        // OPTIONAL METHODS
        // Override bar/separator color.
        setBarColor(Color.parseColor("#3F51B5"));
        setSeparatorColor(Color.parseColor("#2196F3"));

        // Hide Skip/Done button.
        showSkipButton(false);
        setProgressButtonEnabled(false);

        // Turn vibration on and set intensity.
        // NOTE: you will probably need to ask VIBRATE permisssion in Manifest.
        setVibrate(true);
        setVibrateIntensity(30);
    }

    @Override
    public void onSkipPressed() {
    // Do something when users tap on Skip button.
    }

    @Override
    public void onDonePressed() {
    // Do something when users tap on Done button.
    }
    
        @Override
    public void onSlideChanged() {
    // Do something when the slide changes.
    }

    @Override
    public void onNextPressed() {
    // Do something when users tap on Next button.
    }

}

Please, DO NOT override onCreate. Use init instead.

Finally, declare the activity in your Manifest like so:

<activity android:name="com.example.example.intro"
    android:label="@string/app_intro" />

Do not declare the intro as your main app launcher unless you want the intro to launch every time your app starts. Refer to the wiki for an example of how to launch the intro once from your main activity.

Layout 2

If you want to try new layout (as seen in Google's Photo app), just extend AppIntro2 in your Activity. That's all :)

public class MyIntro extends AppIntro2 {
    [...]
}

### Easy implementation of Slide Fragments As you can see, things have changed in AppIntro 3.0.0. Now it's so easy to add new slides to AppIntro.
For example: * Copy the class **SampleSlide** from my [example project](https://github.com/PaoloRotolo/AppIntro/blob/master/example/src/main/java/com/github/paolorotolo/appintroexample/SampleSlide.java). * Add a new slide with ```addSlide(SampleSlide.newInstance(R.layout.your_slide_here));```

There's no need to create one class for fragment anymore. :)

I've never used fragments...

No problem, just use this method and AppIntro will generate a new slide for you.

addSlide(AppIntroFragment.newInstance(title, description, image, background_colour));

Animations

AppIntro comes with some pager animations. Choose the one you like and then active it with:

// Put this method in init()
setFadeAnimation();

Available animations:

setFadeAnimation()
setZoomAnimation()
setFlowAnimation()
setSlideOverAnimation()
setDepthAnimation()

If you want to create nice parallax effect or your own custom animation, create your own PageTransformer and call:

// Put this method in init()
setCustomTransformer(transformer);

Android 6.0 ready

Android 6.0 introduced a new permissions model for developers. Now all your apps have to request permissions which can be a tedious thing to implement.

However, AppIntro simplifies this down to one single line of code!

// Put this in init()
askForPermissions(new String[]{Manifest.permission.CAMERA}, 2); // OR

// This will ask for the camera permission AND the contacts permission on the same slide. 
// Ensure your slide talks about both so as not to confuse the user.
askForPermissions(new String[]{Manifest.permision.CAMERA, Manifest.permission.READ_CONTACTS}, 2); 

NOTE: It is advised that you only put one permission in the String array unless you want the app to ask for multiple permissions on the same slide.

Example

See example code here on Github. You can also see it live. Download this app from Google Play..
