WearImageLoader is an image downloading and caching library for Android Wear

Usage

Use WearImageLoader from your SmartWatch app

Loader.with(context).load("/image/0").into(imageView);
Loader.with(context).load("http://i.imgur.com/o3ELrbX.jpg").into(imageView);

Into an imageview

Loader.with(context).load("/image/0").into(imageView);

Into a FragmentGridPagerAdapter

@Override
public Drawable getBackgroundForRow(final int row) {
    return Loader.with(context).load("/image/" + row).into(this, row);
}

Into a CallBack

Loader.with(context).load("http://i.imgur.com/o3ELrbX.jpg").into(new WearImageLoader.Callback() {
            @Override
            public void onBitmapLoaded(String path, Bitmap bitmap) {

            }
});

By default, the asset name used for the bitmap is "image", you can modify this

Loader.with(context).load("/image/0").setImageAssetName("myImage").into(imageView);

Send Bitmaps

In your smartphone service

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {
        super.onMessageReceived(messageEvent);
        Daemon.with(getApplicationContext()).handleMessage(messageEvent);
        ...
    }

Preload Bitmaps

Send image to wear

Daemon.with(getApplicationContext()).load("http://i.imgur.com/o3ELrbX.jpg").send();

or with "/image/0" path

Daemon.with(getApplicationContext()).load("http://i.imgur.com/o3ELrbX.jpg").into("/image/0");

Image Transformation

You can specify custom transformations on your Bitmaps

public class ResizeTransformation implements Transformation {
    private int targetWidth;

    public ResizeTransformation(int width) {
        this.targetWidth = width;
    }

    @Override
    public Bitmap transform(Bitmap source) {
        double aspectRatio = (double) source.getHeight() / (double) source.getWidth();
        int targetHeight = (int) (targetWidth * aspectRatio);
        Bitmap result = Bitmap.createScaledBitmap(source, targetWidth, targetHeight, false);
        if (result != source) {
            // Same bitmap is returned if sizes are the same
            source.recycle();
        }
        return result;
    }

    @Override
    public String key() {
        return "ResizeTransformation"+targetWidth;
    }
}

Pass an instance of this class to the transform method

Loader.with(context).load(url).transform(new ResizeTransformation(300)).into(imageView);

Prodvided Transformations :

Blur

Loader.with(context).load(url).transform(new BlurTransformation()).into(imageView);

Resizing

Loader.with(context).load(url).transform(new ResizeTransformation(maxWidth)).into(imageView);

Include

Add in your root build.gradle at the end of repositories

allprojects {
		repositories {
			...
			maven { url "https://jitpack.io" }
		}
	}

In your wear module

compile 'de.mdxdave.WearImageLoader:Loader:1.1.1';

In your smartphone module

compile 'de.mdxdave.WearImageLoader:Daemon:1.1.1';

Don't forget to add WRITE_EXTERNAL_STORAGE in your Wear AndroidManifest.xml

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

TODO

• Customize bitmap resizing (actually : width=300px)
• Enabling multiples transformations
• Apply transformations on Smartphone then send them to Wear

Dependencies

• Picasso used in DaVinciDaemon (from Square)
• DiskLruCache used in DaVinci (from JakeWharton)
