How do I download a file via default Android Downloader?

Question

How can I download files using Android downloader? (The downloader that WebBrowser is using that too).

I tried something like this :

Intent i = new Intent(Intent.ACTION_VIEW , Uri.parse("MyUrl"));
startActivity(i);

Any better way?

Edit

I am using Android 2.2

Here you go.

import android.app.Activity;
import android.app.DownloadManager;
import android.app.DownloadManager.Query;
import android.app.DownloadManager.Request;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.ImageView;

public class DownloadManagerActivity extends Activity {
    private long enqueue;
    private DownloadManager dm;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        BroadcastReceiver receiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context context, Intent intent) {
                String action = intent.getAction();
                if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
                    long downloadId = intent.getLongExtra(
                            DownloadManager.EXTRA_DOWNLOAD_ID, 0);
                    Query query = new Query();
                    query.setFilterById(enqueue);
                    Cursor c = dm.query(query);
                    if (c.moveToFirst()) {
                        int columnIndex = c
                                .getColumnIndex(DownloadManager.COLUMN_STATUS);
                        if (DownloadManager.STATUS_SUCCESSFUL == c
                                .getInt(columnIndex)) {

                            ImageView view = (ImageView) findViewById(R.id.imageView1);
                            String uriString = c
                                    .getString(c
                                            .getColumnIndex(DownloadManager.COLUMN_LOCAL_URI));
                            view.setImageURI(Uri.parse(uriString));
                        }
                    }
                }
            }
        };

        registerReceiver(receiver, new IntentFilter(
                DownloadManager.ACTION_DOWNLOAD_COMPLETE));
    }

    public void onClick(View view) {
        dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        Request request = new Request(
                Uri.parse("url for file to download"));
        enqueue = dm.enqueue(request);

    }

    public void showDownload(View view) {
        Intent i = new Intent();
        i.setAction(DownloadManager.ACTION_VIEW_DOWNLOADS);
        startActivity(i);
    }
}

Don't forget to add android.permission.internet in manifest.

@VipulShah Thank you, But DownloadManager is introduced in Android 2.3 and I'm using Android 2.2. So what is the solution? — Kermia, Jun 09 '12 at 06:26
@Kermia: On Android 2.2 and lower, you download the file yourself using `HttpUrlConnection` or `HttpClient`. — CommonsWare, Jun 13 '12 at 13:01

If you want to download it onto the user's SD card from an URL, you can just open it in the phone's default internet browser.

String url = "https://appharbor.com/assets/images/stackoverflow-logo.png";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);

(Code from this question)

The android browser will then start and the file (in this case an image) will be downloaded.

In My sony xepria phone the.The image is shown in the browser it self.What I want is after firing intent when download starts it should move to my app. – Ashwin N Bhanushali Dec 11 '12 at 06:31
If you're trying to download an image then the browser will open the image and view it. This method is meant for binary files such as .zip. I recommend you use Vipul Shah's solution. – Todd Davies Dec 11 '12 at 17:01

You need to use HttpUrlConnection to do this on Android 2.2 and below. There is a very detailed tutorial on the internet that shows you how to do this (with a progress dialog box too).

Remember you must use an AsyncTask or a Thread to ensure that you do not block the UI thread during the actual download!

Thank you, But "How can I download files using default Android downloader?". I think I should use my own solution. – Kermia Jun 14 '12 at 07:03

If you are working on a device that runs Android 2.2 or below, you can't. The default downloader was introduced in 2.3 and thus earlier versions won't recognize it. – Alex Lockwood Jun 14 '12 at 12:28

Yes, you cant perform network operation in the main thread. You can look up to this repository to download file.
