Android Download Manager Tutorial: How to Download files using Download Manager from Internet



1) Android Studio installed on your PC (Unix or Windows). You can learn how to install it here .
2) A real time android device (Smartphone or Tablet) configured with Android Studio. .
3) A basic knowledge of Android lifecycle and different classes & functions used in Android Studio.

Creating a New Project

  1. Go to File → New → New Project and enter your Application Name.
  2. Enter Company Domain, this is used to uniquely identify your App’s package worldwide.
  3. Choose project location and minimum SDK and on the next screen choose Empty Activity, since we would be adding most of the code Ourselves. Then Click on Next.
  4. Choose an Activity Name. Make sure Generate Layout File check box is selected, Otherwise we have to generate it ourselves.Then click on Finish. We have left Activity Name as MainActivity.
  5. Gradle will configure your project and resolve the dependencies, Once it is complete proceed for next steps.
  6. Add Permissions

    Add the following permission to your AndroidManifest.xml file:


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

    Now we will describe each topic in detail through each function which can be implemented through Android Download Manager. We have made separate functions for download data, show status, complete download notification and cancel downloads.

    Generate URI

    First we will have to generate URI from URL. So here we will generate two URI each for Image and Music URL.

    Uri image_uri = Uri.parse("");
    Uri music_uri = Uri.parse("");

    Download Data from URL using Android Download Manager

    DownloadData() function will be used to download data from internet.


    private long DownloadData (Uri uri, View v) {
            long downloadReference;
            // Create request for android download manager
            downloadManager = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
            DownloadManager.Request request = new DownloadManager.Request(uri);
            //Setting title of request
            request.setTitle("Data Download");
            //Setting description of request
            request.setDescription("Android Data download using DownloadManager.");
            //Set the local destination for the downloaded file to a path within the application's external files directory
            if(v.getId() ==
              request.setDestinationInExternalFilesDir(MainActivity.this, Environment.DIRECTORY_DOWNLOADS,"AndroidTutorialPoint.mp3");
            else if(v.getId() ==
              request.setDestinationInExternalFilesDir(MainActivity.this, Environment.DIRECTORY_DOWNLOADS,"AndroidTutorialPoint.jpg");
            //Enqueue download and save into referenceId
            downloadReference = downloadManager.enqueue(request);
            Button DownloadStatus = (Button) findViewById(;
            Button CancelDownload = (Button) findViewById(;
            return downloadReference;

    Description of above code:

    1) downloadReference : It is a unique id that we will refer for specific download request.
    2) request : Instance of DownloadManager will be created through getSystemService by passing DOWNLOAD_SERVICE. A new request is generated in the next statement using DownloadManager.Request(uri).
    3) setDestinationInExternalFilesDir : This will be used to save file in external downloads folder.
    4) downloadManager.enqueue(request) : Enqueue a new download corresponding to request. The download will start automatically once the download manager is ready to execute it and connectivity is available.

    Check Download Status

    Check_Image_Status() function will be used to get the status of the Image Download. Refer following code:


    private void Check_Image_Status(long Image_DownloadId) {
            DownloadManager.Query ImageDownloadQuery = new DownloadManager.Query();
            //set the query filter to our previously Enqueued download
            //Query the download manager about downloads that have been requested.
            Cursor cursor = downloadManager.query(ImageDownloadQuery);
                DownloadStatus(cursor, Image_DownloadId);

    Description of above code:

    1) DownloadManager.Query() : This is used to filter android download manager queries. Here we are providing Image_DownloadId in setFilterById() to include only downloads with given Id.

    2) downloadManager.query(ImageDownloadQuery): This is used to Query the android download manager about downloads that have been requested.

    3) Cursor: A Cursor over the result set of downloads, with columns consisting of all the COLUMN_* constants. Now this cursor will be used to get the status of download in DownloadStatus() function.


    private void DownloadStatus(Cursor cursor, long DownloadId){
            //column for download  status
            int columnIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
            int status = cursor.getInt(columnIndex);
            //column for reason code if the download failed or paused
            int columnReason = cursor.getColumnIndex(DownloadManager.COLUMN_REASON);
            int reason = cursor.getInt(columnReason);
            //get the download filename
            int filenameIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_FILENAME);
            String filename = cursor.getString(filenameIndex);
            String statusText = "";
            String reasonText = "";
                case DownloadManager.STATUS_FAILED:
                    statusText = "STATUS_FAILED";
                        case DownloadManager.ERROR_CANNOT_RESUME:
                            reasonText = "ERROR_CANNOT_RESUME";
                        case DownloadManager.ERROR_DEVICE_NOT_FOUND:
                            reasonText = "ERROR_DEVICE_NOT_FOUND";
                        case DownloadManager.ERROR_FILE_ALREADY_EXISTS:
                            reasonText = "ERROR_FILE_ALREADY_EXISTS";
                        case DownloadManager.ERROR_FILE_ERROR:
                            reasonText = "ERROR_FILE_ERROR";
                        case DownloadManager.ERROR_HTTP_DATA_ERROR:
                            reasonText = "ERROR_HTTP_DATA_ERROR";
                        case DownloadManager.ERROR_INSUFFICIENT_SPACE:
                            reasonText = "ERROR_INSUFFICIENT_SPACE";
                        case DownloadManager.ERROR_TOO_MANY_REDIRECTS:
                            reasonText = "ERROR_TOO_MANY_REDIRECTS";
                        case DownloadManager.ERROR_UNHANDLED_HTTP_CODE:
                            reasonText = "ERROR_UNHANDLED_HTTP_CODE";
                        case DownloadManager.ERROR_UNKNOWN:
                            reasonText = "ERROR_UNKNOWN";
                case DownloadManager.STATUS_PAUSED:
                    statusText = "STATUS_PAUSED";
                        case DownloadManager.PAUSED_QUEUED_FOR_WIFI:
                            reasonText = "PAUSED_QUEUED_FOR_WIFI";
                        case DownloadManager.PAUSED_UNKNOWN:
                            reasonText = "PAUSED_UNKNOWN";
                        case DownloadManager.PAUSED_WAITING_FOR_NETWORK:
                            reasonText = "PAUSED_WAITING_FOR_NETWORK";
                        case DownloadManager.PAUSED_WAITING_TO_RETRY:
                            reasonText = "PAUSED_WAITING_TO_RETRY";
                case DownloadManager.STATUS_PENDING:
                    statusText = "STATUS_PENDING";
                case DownloadManager.STATUS_RUNNING:
                    statusText = "STATUS_RUNNING";
                case DownloadManager.STATUS_SUCCESSFUL:
                    statusText = "STATUS_SUCCESSFUL";
                    reasonText = "Filename:\n" + filename;
            if(DownloadId == Music_DownloadId) {
                Toast toast = Toast.makeText(MainActivity.this,
                        "Music Download Status:" + "\n" + statusText + "\n" +
                toast.setGravity(Gravity.TOP, 25, 400);
            else {
                Toast toast = Toast.makeText(MainActivity.this,
                        "Image Download Status:"+ "\n" + statusText + "\n" +
                toast.setGravity(Gravity.TOP, 25, 400);
                // Make a delay of 3 seconds so that next toast (Music Status) will not merge with this one.
                final Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    public void run() {
                }, 3000);

    Above code is pretty much self explanatory. We are simply printing status according to value of COLUMN_REASON returned by Android Download Manager.

    Similarly we have made function for checking status of Music file i.e. Check_Music_Status().

    Cancel all Downloads

    To cancel a download we will simply use:


    The Broadcast Receivers

    The last part of our tutorial is broadcast receiver. Android DownloadManager send ACTION_DOWNLOAD_COMPLETE broadcast intent when a download completes. So we will set filter when download completes and register receiver:

    IntentFilter filter = new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE);
    registerReceiver(downloadReceiver, filter);
    private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
            public void onReceive(Context context, Intent intent) {
                //check if the broadcast message is for our enqueued download
                long referenceId = intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1);
                if(referenceId == Image_DownloadId) {
                    Toast toast = Toast.makeText(MainActivity.this,
                            "Image Download Complete", Toast.LENGTH_LONG);
                    toast.setGravity(Gravity.TOP, 25, 400);
                else if(referenceId == Music_DownloadId) {
                    Toast toast = Toast.makeText(MainActivity.this,
                            "Music Download Complete", Toast.LENGTH_LONG);
                    toast.setGravity(Gravity.TOP, 25, 400);

    So in the above code broadcast Intent is received, its referenceId is compared and accordingly Toast message is displayed.
