Android Download Manager Completed

Android download manager completed

A broadcast is sent by the DownloadManager whenever a download completes, so you need to register a broadcast receiver with the appropriate intent action( ACTION_DOWNLOAD_COMPLETE ) to catch this broadcast:

To register receiver

registerReceiver(onComplete, new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE));

and a BroadcastReciever handler

BroadcastReceiver onComplete=new BroadcastReceiver() {
    public void onReceive(Context ctxt, Intent intent) {
        // your code
    }
};

You can also create AsyncTask to handle the downloading of big files

Create a download dialog of some sort to display downloading in notification area and than handle the opening of the file:

protected void openFile(String fileName) {
    Intent install = new Intent(Intent.ACTION_VIEW);
    install.setDataAndType(Uri.fromFile(new File(fileName)),"MIME-TYPE");
    startActivity(install);
}

How to notify after all download completed from Android download manager

Add a check before notifying all downloads are completed. like

query.setFilterByStatus(DownloadManager.STATUS_PAUSED |
      DownloadManager.STATUS_PENDING |
      DownloadManager.STATUS_RUNNING);
    Cursor cursor = downloadManager.query(query);
    if (cursor != null && cursor.getCount() > 0) {
      return;
    }else {
      query.setFilterById(receivedID);
      //proceed your...
    }

How can I wait until DownloadManager is complete?

Use a BroadcastReceiver to detect when the download finishes:

public class DownloadBroadcastReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();

        if (DownloadManager.ACTION_DOWNLOAD_COMPLETE.equals(action)) {
            //Show a notification
        }
    }
}

and register it in your manifest:

<receiver android:name=".DownloadBroadcastReceiver">
    <intent-filter>
        <action android:name="android.intent.action.DOWNLOAD_COMPLETE"/>
    </intent-filter>
</receiver>

Finding download complete from downloadManager in android

I found my answer at : DownloadManager.ACTION_DOWNLOAD_COMPLETE broadcast receiver receiving same download id more than once with different download statuses in Android

and the code for me goes like this:

private boolean downloadComplete(long downloadId){
        DownloadManager dMgr = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
        Cursor c= dMgr.query(new DownloadManager.Query().setFilterById(downloadId));

        if(c.moveToFirst()){
            int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));

            if(status == DownloadManager.STATUS_SUCCESSFUL){
                return true; //Download completed, celebrate
            }else{
                int reason = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_REASON));
                Log.d(TAG, "Download not correct, status [" + status + "] reason [" + reason + "]");
                return false;
            }
        }
        return false;
    }
