• speed test upload
• download / upload progress monitoring
• configurable hostname / port / uri (username & password for FTP)
• configurable socket timeout and chunk size
• configure upload file storage

Check a non-exhaustive list of compatible speed test server.

Include in your project

• with Gradle, from jcenter or mavenCentral :

compile 'fr.bmartel:jspeedtest:1.32.1'

Usage

• setup a speed test listener to monitor progress, completion and error catch :

SpeedTestSocket speedTestSocket = new SpeedTestSocket();

// add a listener to wait for speedtest completion and progress
speedTestSocket.addSpeedTestListener(new ISpeedTestListener() {

    @Override
    public void onCompletion(SpeedTestReport report) {
        // called when download/upload is complete
        System.out.println("[COMPLETED] rate in octet/s : " + report.getTransferRateOctet());
        System.out.println("[COMPLETED] rate in bit/s   : " + report.getTransferRateBit());
    }

    @Override
    public void onError(SpeedTestError speedTestError, String errorMessage) {
         // called when a download/upload error occur
    }

    @Override
    public void onProgress(float percent, SpeedTestReport report) {
        // called to notify download/upload progress
        System.out.println("[PROGRESS] progress : " + percent + "%");
        System.out.println("[PROGRESS] rate in octet/s : " + report.getTransferRateOctet());
        System.out.println("[PROGRESS] rate in bit/s   : " + report.getTransferRateBit());
    }
});

Download

• HTTP download 1Mo from http://ipv4.ikoula.testdebit.info

speedTestSocket.startDownload("http://ipv4.ikoula.testdebit.info/1M.iso");

• FTP download 1Mo from speedtest.tele2.net

speedTestSocket.startDownload("ftp://speedtest.tele2.net/1MB.zip");

• FTP download 1Mo from ftp.otenet.gr with credentials (username/password), default is anonymous/no password

speedTestSocket.startDownload("ftp://speedtest:speedtest@ftp.otenet.gr/test1Mb.db");

Upload

• HTTP upload 1Mo to http://ipv4.ikoula.testdebit.info

speedTestSocket.startUpload("http://ipv4.ikoula.testdebit.info/", 1000000);

• FTP upload a 1Mo file to speedtest.tele2.net

String fileName = SpeedTestUtils.generateFileName() + ".txt";
speedTestSocket.startUpload("ftp://speedtest.tele2.net/upload/" + fileName, 1000000);

Fixed duration download

Download during a fixed duration. Download will be stopped when the max duration is reached.

• HTTP download for 10s max, a 100 Mo file from http://ipv4.ikoula.testdebit.info

speedTestSocket.startFixedDownload("http://ipv4.ikoula.testdebit.info/100M.iso", 10000);

• FTP download for 10s max, a 100 Mo file from speedtest.tele2.net

speedTestSocket.startFixedDownload("ftp://speedtest.tele2.net/100MB.zip");

Fixed duration Upload

Upload during a fixed duration. Upload will be stopped when the max duration is reached

• HTTP upload for 10s max, a 10Mo file to http://ipv4.ikoula.testdebit.info

speedTestSocket.startFixedUpload("http://ipv4.ikoula.testdebit.info/", 10000000, 10000);

• FTP upload for 10s max, a 10Mo file to speedtest.tele2.net

String fileName = SpeedTestUtils.generateFileName() + ".txt";
speedTestSocket.startFixedUpload("ftp://speedtest.tele2.net/upload/" + fileName, 10000000, 10000);

Define report interval

You can define your own report interval (interval between each onDownloadProgress & onUploadProgress) in milliseconds.

• HTTP download with download reports each 1.5 seconds

speedTestSocket.startDownload("http://ipv4.ikoula.testdebit.info/1M.iso", 1500);

• FTP download with download reports each 1.5 seconds

speedTestSocket.startDownload("ftp://speedtest.tele2.net/1MB.zip", 1500);

• HTTP upload with upload reports each 1.5 seconds

speedTestSocket.startUpload("http://ipv4.ikoula.testdebit.info/", 10000000, 1500);

• FTP upload with upload reports each 1.5 seconds

String fileName = SpeedTestUtils.generateFileName() + ".txt";
speedTestSocket.startUpload("ftp://speedtest.tele2.net/upload/" + fileName, 10000000, 1500);

Use proxy server

speedTestSocket.setProxyServer("http://216.56.48.118:9000");

default proxy server port is 8080

Chain download/upload requests

You can chain multiple download/upload requests during a fixed duration. This way, there will be as much download/upload request until the end of the period

• download repeat

The following will download regularly for 20 seconds a file of 1Mo with download report each 2 seconds. Download reports will appear in onReport callback of IRepeatListener instead of onDownloadProgress :

speedTestSocket.startDownloadRepeat("http://ipv4.ikoula.testdebit.info/1M.iso",
    20000, 2000, new
            IRepeatListener() {
                @Override
                public void onCompletion(final SpeedTestReport report) {
                    // called when repeat task is finished
                }

                @Override
                public void onReport(final SpeedTestReport report) {
                    // called when a download report is dispatched
                }
            });

• upload repeat

The following will upload regularly for 20 seconds a file of 1Mo with download report each 2 seconds. Upload reports will appear in onReport callback of IRepeatListener instead of onUploadProgress :

speedTestSocket.startUploadRepeat("http://ipv4.ikoula.testdebit.info/", 1000000
    20000, 2000, new
            IRepeatListener() {
                @Override
                public void onCompletion(final SpeedTestReport report) {
                    // called when repeat task is finished
                }

                @Override
                public void onReport(final SpeedTestReport report) {
                    // called when an upload report is dispatched
                }
            });

Get live download & upload

• retrieve current download report :

SpeedTestReport getLiveReport()

• retrieve current upload report :

SpeedTestReport getLiveReport()

Set setup time

Setup time is the amount of time in milliseconds from which speed test will be calculated :

The following will set the setup time to 5 seconds which mean, the speed rate will begin to be computed 5 seconds after the speed test start :

• download

speedTestSocket.setDownloadSetupTime(5000);

• upload

speedTestSocket.setUploadSetupTime(5000);

Set upload file storage type

By default, data to be uploaded is stored in RAM, for large data it is recommended to used file storage :

speedTestSocket.setUploadStorageType(UploadStorageType.FILE_STORAGE);

It will create a temporary file containing random data. File will be deleted automatically at the end of the upload.

Set size of each packet sent to upload server

speedTestSocket.setUploadChunkSize(65535);

Set socket timeout value

You can set download/upload socket timeout in milliseconds :

speedTestSocket.setSocketTimeout(5000);

Set transfer rate precision

These settings are used to alter transfer rate float rounding / scale :

• set RoundingMode :

speedTestSocket.setDefaultRoundingMode(RoundingMode.HALF_EVEN);

Default RoundingMode used for transfer rate calculation is HALF_EVEN. It can be override with :

• set Scale :

speedTestSocket.setDefaultScale(4);

Default scale used for transfer rate calculation is 4

FTP mode

Set passive/active mode with :

speedTestSocket.setFtpMode(FtpMode.ACTIVE);

default is FtpMode.PASSIVE

Android Integration

• add Internet permission to manifest :

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

• use an AsyncTask to run your speed test :

public class SpeedTestTask extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {

        SpeedTestSocket speedTestSocket = new SpeedTestSocket();

        // add a listener to wait for speedtest completion and progress
        speedTestSocket.addSpeedTestListener(new ISpeedTestListener() {

            @Override
            public void onCompletion(SpeedTestReport report) {
                // called when download/upload is finished
                Log.v("speedtest", "[COMPLETED] rate in octet/s : " + report.getTransferRateOctet());
                Log.v("speedtest", "[COMPLETED] rate in bit/s   : " + report.getTransferRateBit());
            }

            @Override
            public void onError(SpeedTestError speedTestError, String errorMessage) {
                // called when a download/upload error occur
            }

            @Override
            public void onProgress(float percent, SpeedTestReport report) {
                // called to notify download/upload progress
                Log.v("speedtest", "[PROGRESS] progress : " + percent + "%");
                Log.v("speedtest", "[PROGRESS] rate in octet/s : " + report.getTransferRateOctet());
                Log.v("speedtest", "[PROGRESS] rate in bit/s   : " + report.getTransferRateBit());
            }
        });

        speedTestSocket.startDownload("http://ipv4.ikoula.testdebit.info/1M.iso");

        return null;
    }
}

Execute it with : new SpeedTestTask().execute();

Speed Test issues

It's important to choose an adequate speed test server depending on latency/jitter. This library is not responsible for the speed test server choice.

Note that this library :

• doesn't adjust the chunk size depending on the connection speed either
• doesn't provide pre-estimation of the connection speed based on small chunk sent to/from server
• doesn't detect anomaly either (for instance taking away X% slowest chunk and X% fastest chunk downloaded)

This library does provide an average of transfer rate for all individual chunks read/written for download/upload.
