FloodMonitoring
Android library for the gov.uk Flood Monitoring API: http://environment.data.gov.uk/flood-monitoring/doc/reference
The Flood Monitoring API is RESTful and follows HATEOAS, this means where the Android library requires a url you can use the id of an object: getId()
A couple of apps using this library:
Flood Alerts: https://play.google.com/store/apps/details?id=eu.fiskur.floodmonitor
River Levels: https://play.google.com/store/apps/details?id=eu.fiskur.riverlevels
The library uses RxJava, example usage:
FloodMonitoring.getInstance().getThreeDayForecast() .observeOn(AndroidSchedulers.mainThread()) .subscribeOn(Schedulers.newThread()) .subscribe(new Observer<ThreeDayForecast>() {
@Override
public void onCompleted() {
}
@Override
public void onError(Throwable e) {
//...
}
@Override
public void onNext(ThreeDayForecast threeDayForecast) {
outputForecast(threeDayForecast);
}
}
);
#Dependency
Add jitpack.io to your root build.gradle, eg:
allprojects {
repositories {
jcenter()
maven {
url "https://jitpack.io"
}
}
}
then add the dependency to your project build.gradle:
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.github.fiskurgit:FloodMonitoring:1.5'
}
You can find the latest version in the releases tab above: https://github.com/fiskurgit/FloodMonitoring/releases

#Licence
Full licence here: https://github.com/fiskurgit/FloodMonitoring/blob/master/LICENSE.md
In short:
The MIT License is a permissive license that is short and to the point. It lets people do anything they want with your code as long as they provide attribution back to you and don’t hold you liable.
#Logging
You can turn on logging to see the network response:
FloodMonitoring.getInstance().logOutput(true);
Then register a log listener:
FloodApiLogger.getInstance().setApiLogListener(new FloodApiLogger.ApiLogListener() {
@Override
public void apiLog(String message) {
Log.d(TAG, message);
}
}
);
#3 Day Forecast
getThreeDayForecast() returns a general overview of the forecast for England and Wales over the next 3 days. A small image of the UK marked with forecast warnings can be fetched using getDayImageBytes(int day) (with 1, 2, or 3) this returns a Retrofit ResponseBody containing the image bytes, a convenience method in the utils class helps populate an ImageView: FloodUtils.loadImage(responseBody, imageView). Alternatively get the image URLs for use with Picasso or similar: getDayImageUrl(int day).
#Flood Warnings
getAllWarnings() returns List<FloodWarning> of all current alerts (including any that have been removed in the last 24 hours, use getSeverityLevel() to build your UI).
getAreaWarnings(double latitude, double longitude, int distance) returns List<FloodWarning> of any flood alerts in the area.
getFloodAreaFromUrl(String url) returns the FloodArea including latitude and longitude for plotting warning locations on a map.
#Water Level Stations
getAreaStations(double latitude, double longitude, int distance) returns List<StationOverview> containing some detail, but you should use the id to fetch the full StationDetail object: getStation(String url).
getReadings(String url, int count) gets the last count Reading objects, normally taken at 15 minute intervals that you can use to create graphs, you can also use getReadingsToday(String url) and getReadingsDays(String url, int days) which will ge the last x days worth of readings (although the API docs state data is held for a month it only seems to return up to two weeks worth of readings).
