APNG View

APNG View is a library that supports playing animation from APNG image files on Android application.

Usage

To load an image and start/stop an animation on users click

@Override
protected void onCreate(Bundle savedInstanceState) {
    ...
    ImageView imageView = (ImageView) findViewById(R.id.image_view1);

    // Display image from a file in assets
    String uri = "assets://apng/apng_geneva_drive.png";
    ApngImageLoader.getInstance().displayImage(uri, imageView);

    imageView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                ApngDrawable apngDrawable = ApngDrawable.getFromView(v);
                if (apngDrawable == null) return;

                if (apngDrawable.isRunning()) {
                    apngDrawable.stop(); // Stop animation
                } else {
                    apngDrawable.setNumPlays(3); // Fix number of repetition
                    apngDrawable.start(); // Start animation
                }
            }
    });
}

To start an animation immediately after an image has finished loading, passing an object of ApngConfig to the method displayApng(), see the example code below.

ApngImageLoader.getInstance()
    .displayApng(uri, imageView, 
        new ApngImageLoader.ApngConfig(3, true));

ApngConfig has 2 attributes e.g. number of repetition and auto-start. If the number of repetition is less than 1, the library will try to grab the meta-data from APNG source file, if it's not specified, the animation will be playing continuously.

Different formats of URI that are also supported:

String uri = "file:///sdcard/apng_geneva_drive.png"

And

String uri = "http://littlesvr.ca/apng/images/clock.png"

Installation

Use Gradle:

dependencies {
    compile 'com.github.sahasbhop:apng-view:1.3'

public class MyApplication extends Application {
    @Override
    public void onCreate() {
        super.onCreate();
        .. // Initializing stuffs e.g. Google Analytics, Crashlytics, etc.
        ApngImageLoader.getInstance().init(getApplicationContext());
    }
}
