All Implemented Interfaces:

DeviceAtlasApi

Direct Known Subclasses:

DeviceApiWeb, DeviceApiWebJakarta

public class DeviceApi
extends BaseDeviceAtlasApi

The DeviceAtlas device detection API provides a way to detect devices based on the HTTP headers. Using these headers, the API returns device properties such as screen width, screen height, is mobile, vendor, model etc. If you want to use the DeviceAtlas API in a servlet container then it is strongly recommended to use DeviceApiWeb instead of this library.

The DeviceApiWeb is preferred when you want to perform real-time detection of a user's device in a servlet container.

The DeviceApi is preferred when you want to perform device outside of a servlet container or from an off-line User-Agent list or header set.

getProperties(Map<String, String> headers, String clientSide).

To get the most accurate results: 1- Pass all of the HTTP headers. 2- Use the DeviceAtlas Client-side component and pass the result.

When you have limited data you can also use these alternatives:

getProperties(Map<String, String> headers).

getProperties(String userAgent, String clientSide).

getProperties(String userAgent).

Example usage:

 Map<String, String> headers = new HashMap<>();
 headers.put("user-agent", "...");
 headers.put("accept-language", "...");
 // add any other available header...

 DeviceApi deviceApi = new DeviceApi();

 try {
     DeviceApi.loadDataFromFile("/path/to/datafile.json");

     // get all properties from the headers
     Properties props = DeviceApi.getProperties(headers);

     // .... use the properties ....
     if (props.contains("isMobilePhone", true)) {
         // it is a mobile phone
     }
     if (props.containsKey("model")) {
         String deviceModel = props.get("model").asString();
     }
     if (props.containsKey("yearReleased")) {
         int deviceModel = props.get("yearReleased").asInteger();
     }
 } catch (...) {
     ...
 }

Method Detail

loadDataFromClassPath

public void loadDataFromClassPath(java.lang.String fileName)
                           throws DataLoadingException

Load the DeviceAtlas device detection data into the API from a JSON file form the class path. The JSON data file is provided by the DeviceAtlas website.

Parameters:

fileName - The JSON file-name

Throws:

DataLoadingException

loadDataFromFile

public void loadDataFromFile(java.lang.String jsonDataFilePath)
                      throws DataLoadingException

Load the DeviceAtlas device detection data into the API from a JSON file. The JSON data file is provided by the DeviceAtlas website.

Parameters:

jsonDataFilePath - Path to the JSON file

Throws:

DataLoadingException

loadDataFromStream

public void loadDataFromStream(java.io.InputStream inputStream)
                        throws DataLoadingException

Load the DeviceAtlas device detection data into the API from an input stream.

Parameters:

inputStream - Input stream

Throws:

DataLoadingException

getPropertyNames

public java.util.Set<PropertyName> getPropertyNames()

Get a set of all possible property names. Note that the client side properties are not included in this set.

Returns:

A set of all possible device property names as PropertyName objects.

getApiVersion

public static java.lang.String getApiVersion()

The version of this API.

Returns:

DeviceApi version

getDataVersion

public java.lang.String getDataVersion()

The version of the data file.

Returns:

The device data file version.

getDataCreationTimestamp

public java.lang.Integer getDataCreationTimestamp()

The creation date/time of the loaded data file as a Unix timestamp.
