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)
