Comprehensive Uno documentation for Novices-to-Intermediates

Hey guys.

I am trying to port foreign android java code into fuse but I have no idea where to start, the class reference and current documentation rather too daunting for a novice like myself.

I feel there needs to be a “Basics of Uno”, or “Getting Started with Uno” to help ease developers into using Uno.

What I am trying to do currently is include camera video recording functionality into fuse. Not sure how to do that. I am going to the java code below.

package com.rohmbus.camvideorecord;

import java.text.SimpleDateFormat;
import android.content.Intent;
import android.os.Bundle;
import android.os.Environment;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

private Uri fileUri;
public static final int MEDIA_TYPE_VIDEO = 2;
private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;
public static MainActivity ActivityContext =null;
public static TextView output;

public void onCreate(Bundle savedInstanceState) {

    ActivityContext = this;

    Button buttonRecording = (Button)findViewById(;
    output = (TextView)findViewById(;

    buttonRecording.setOnClickListener(new Button.OnClickListener(){

        public void onClick(View arg0) {

            // create new Intentwith with Standard Intent action that can be
            // sent to have the camera application capture an video and return it.
            Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);

            // create a file to save the video
            fileUri = getOutputMediaFileUri(MEDIA_TYPE_VIDEO);

            // set the image file name
            intent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);

            // set the video image quality to high
            intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

            // start the Video Capture Intent
            startActivityForResult(intent, CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE);



/** Create a file Uri for saving an image or video */
private static Uri getOutputMediaFileUri(int type){

    return Uri.fromFile(getOutputMediaFile(type));

/** Create a File for saving an image or video */
private static File getOutputMediaFile(int type){

    // Check that the SDCard is mounted
    File mediaStorageDir = new File(Environment.getExternalStoragePublicDirectory(
            Environment.DIRECTORY_PICTURES), "MyCameraVideo");

    // Create the storage directory(MyCameraVideo) if it does not exist
    if (! mediaStorageDir.exists()){

        if (! mediaStorageDir.mkdirs()){

            output.setText("Failed to create directory MyCameraVideo.");

            Toast.makeText(ActivityContext, "Failed to create directory MyCameraVideo.",

            Log.d("MyCameraVideo", "Failed to create directory MyCameraVideo.");
            return null;

    // Create a media file name

    // For unique file name appending current timeStamp with file name
    java.util.Date date= new java.util.Date();
    String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")

    File mediaFile;

    if(type == MEDIA_TYPE_VIDEO) {

        // For unique video file name appending current timeStamp with file name
        mediaFile = new File(mediaStorageDir.getPath() + File.separator +
                "VID_"+ timeStamp + ".mp4");

    } else {
        return null;

    return mediaFile;

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    // After camera screen this code will excuted


        if (resultCode == RESULT_OK) {

            output.setText("Video File : " +data.getData());

            // Video captured and saved to fileUri specified in the Intent
            Toast.makeText(this, "Video saved to:\n" +
                    data.getData(), Toast.LENGTH_LONG).show();

        } else if (resultCode == RESULT_CANCELED) {

            output.setText("User cancelled the video capture.");

            // User cancelled the video capture
            Toast.makeText(this, "User cancelled the video capture.",

        } else {

            output.setText("Video capture failed.");

            // Video capture failed, advise user
            Toast.makeText(this, "Video capture failed.",



We are constantly trying to improve on our documentation. Our main focus has been on the UX documentation, but i agree, we have to eventually add some more content to cover these more advanced use-cases. Hopefully we’ll get a chance to do that in the not too distant future.

If you need some more foreign code to look at for inspiration, the FuseCloud app implements a music player which you might be able to learn from.

Fuse already supports camera, however video is not yet supported out of the box.
