A reactive extension to generate URL previews.
This library parses available open graph data from the provided url and returns them as a simple model class. Otherwise, the library searches for other fallbacks and returns them instead.
Image dimensions are read from its uri by fetching the required bytes and then sorted according to their resolution.
To use the library, add the following dependency to your build.gradle
dependencies {
compile 'com.schinizer:rxunfurl:0.1.1'
}To generate previews, simply subscribe to RxUnfurl.generatePreview(yourURL).
If you are on android, you will need RxAndroid to subscribe to network calls on another thread.
RxUnfurl.generatePreview("http://9gag.com")
.subscribeOn(Schedulers.io())
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Action1<PreviewData>() {
@Override
public void call(PreviewData previewData) {
}
}, new Action1<Throwable>() {
@Override
public void call(Throwable throwable) {
}
});This library uses okhttp for network calls. If you will like to supply your instance, call:
RxUnfurl.setInternalClient(yourOKhttpClient);You may find a sample android implementation in /app.
