An Android Integration for Transloadit's file uploading and encoding service

Intro

Transloadit is a service that helps you handle file uploads, resize, crop and watermark your images, make GIFs, transcode your videos, extract thumbnails, generate audio waveforms, and so much more. In short, Transloadit is the Swiss Army Knife for your files.

This is an Android SDK to make it easy to talk to the Transloadit REST API.

Install

The JARs can be downloaded manually from Maven Central.

Gradle:

implementation 'com.transloadit.android.sdk:transloadit-android:0.0.10'

Maven:

<dependency>
  <groupId>com.transloadit.android.sdk</groupId>
  <artifactId>transloadit-android</artifactId>
  <version>0.0.10</version>
</dependency>

Usage

All interactions with the SDK begin with the com.transloadit.android.sdk.Transloadit class.

Create an Assembly

To create an assembly, you use the newAssembly method.

To use this functionality in it's full glory, you need implement the AssemblyProgressListener interface.

public class MyAssemblyProgressListener  implements AssemblyProgressListener {
    @Override
    public void onUploadFinished() {
        System.out.println("upload finished!!! waiting for execution ...");
    }

    @Override
    public void onUploadProgress(long uploadedBytes, long totalBytes) {
        System.out.println("uploaded: " + uploadedBytes + " of: " + totalBytes);
    }

    @Override
    public void onAssemblyFinished(AssemblyResponse response) {
        System.out.println("Assembly finished with status: " + response.json().getString("ok"));
    }

    @Override
    public void onUploadFailed(Exception exception) {
        System.out.println("upload failed :(");
        exception.printStackTrace();
    }

    @Override
    public void onAssemblyStatusUpdateFailed(Exception exception) {
        System.out.println("unable to fetch status update :(");
        exception.printStackTrace();
    }
}

And in your activity you can have something like this

public class MainActivity extends AppCompatActivity {
    private ProgressBar progressBar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        progressBar = (ProgressBar) findViewById(R.id.progressBar);

        AssemblyProgressListener listener = new MyAssemblyProgressListener();

        AndroidTransloadit transloadit = new AndroidTransloadit("key", "secret");
        AndroidAsyncAssembly assembly = transloadit.newAssembly(listener);
        assembly.addFile(new File("path/to/file.jpg"), "file");

        Map<String, Object> stepOptions = new HashMap<>();
        stepOptions.put("width", 75);
        stepOptions.put("height", 75);
        stepOptions.put("resize_strategy", "pad");
        assembly.addStep("resize", "/image/resize", stepOptions);

        assembly.save();
    }
}
