tus is a protocol based on HTTP for resumable file uploads. Resumable means that an upload can be interrupted at any moment and can be resumed without re-uploading the previous data again. An interruption may happen willingly, if the user wants to pause, or by accident in case of an network issue or server outage.

tus-android-client is a library meant to be used in addition to tus-java-client for uploading files using the tus protocol to any remote server supporting it. This package provides additional classes which makes interacting with the Java library easier on Android.


// This example consumes the tus-java-client and tus-android-client libraries

// Create a new TusClient instance
TusClient client = new TusClient();

// Configure tus HTTP endpoint. This URL will be used for creating new uploads
// using the Creation extension
client.setUploadCreationURL(new URL(""));

// Enable resumable uploads by storing the upload URL in the preferences
// and preserve them after app restarts
SharedPreferences pref = getSharedPreferences("tus", 0);
client.enableResuming(new TusPreferencesURLStore(pref));

// Open a file using which we will then create a TusUpload. If you do not have
// a File object, you can manually construct a TusUpload using an InputStream.
// See the documentation for more information.
File file = new File("./cute_kitten.png");
final TusUpload upload = new TusUpload(file);

System.out.println("Starting upload...");

// We wrap our uploading code in the TusExecutor class which will automatically catch
// exceptions and issue retries with small delays between them and take fully
// advantage of tus' resumability to offer more reliability.
// This step is optional but highly recommended.
TusExecutor executor = new TusExecutor() {
    protected void makeAttempt() throws ProtocolException, IOException {
        // First try to resume an upload. If that's not possible we will create a new
        // upload and get a TusUploader in return. This class is responsible for opening
        // a connection to the remote server and doing the uploading.
        TusUploader uploader = client.resumeOrCreateUpload(upload);

        // Upload the file in chunks of 1KB sizes.

        // Upload the file as long as data is available. Once the
        // file has been fully uploaded the method will return -1
        do {
            // Calculate the progress using the total size of the uploading file and
            // the current offset.
            long totalBytes = upload.getSize();
            long bytesUploaded = uploader.getOffset();
            double progress = (double) bytesUploaded / totalBytes * 100;

            System.out.printf("Upload at %06.2f%%.\n", progress);
        } while(uploader.uploadChunk() > -1);

        // Allow the HTTP connection to be closed and cleaned up

        System.out.println("Upload finished.");
        System.out.format("Upload available at: %s", uploader.getUploadURL().toString());

The example application provides a more complete example in terms of interacting with the Android platform.


The JARs can be downloaded manually from our Bintray project. tus-java-client is also available in JCenter (Maven Central is coming soon).
