Cannot get status of download manager in android - android

I am working with android.I am trying to get the status of downloading using download manager.But it does not work. I used the following code
DownloadManager.Query query = null;
Log.i("service1", "blah");
Cursor c = null;
DownloadManager downloadManager = null;
downloadManager = (DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Log.i("service2", "blah");
query = new DownloadManager.Query();
if(query!=null) {
Log.i("service3", "blah");
query.setFilterByStatus(DownloadManager.STATUS_FAILED|DownloadManager.STATUS_PAUSED|DownloadManager.STATUS_SUCCESSFUL|
DownloadManager.STATUS_RUNNING|DownloadManager.STATUS_PENDING);
} else {
Log.i("service4", "blah");
return;
}
c = downloadManager.query(query);
if(c.moveToFirst()) {
Log.i("service5", "blah");
int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
Log.i("service6", "blah");
switch(status) {
case DownloadManager.STATUS_PAUSED:
break;
case DownloadManager.STATUS_PENDING:
break;
case DownloadManager.STATUS_RUNNING:
Toast.makeText(this, "Download started", Toast.LENGTH_SHORT).show();
break;
case DownloadManager.STATUS_SUCCESSFUL:
Toast.makeText(this, "Download completed", Toast.LENGTH_SHORT).show();
break;
case DownloadManager.STATUS_FAILED:
break;
}
}
It does not enter into if(c.moveToFirst()). Or any other way to get the download status in Android?

Downloading a zip file using download manager

I want to download a zip file using download manager.Using this code it shows downloading file in notification and later shows download failed. I gave permissions such as read and write external directory.My code is as follows:
if(DownloadTask.readAndWriteExternalStorage(context)){
downloadManager=
(DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Uri uri=Uri.parse("url of zip");
DownloadManager.Request request= new
DownloadManager.Request(uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE|
DownloadManager.Request.NETWORK_WIFI);
request.setVisibleInDownloadsUi(true);
request.setTitle("Example");
request.setDescription("Downloading a very large zip");
request.setAllowedOverRoaming(true);
request.setMimeType("df.zip");
request.allowScanningByMediaScanner();
request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS,
"df.zip");
request.setNotificationVisibility(DownloadManager.
Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
Long reference=downloadManager.enqueue(request);
}
I solved the issue with this:
DownloadManager downloadManager;

} else if (uri.toString().endsWith(".zip")) {

How to get the Download Manager ,download cancel callback? or else how to hide or remove this cancel from notification?

When a video is being downloaded there is a cancel option to cancel the download.but when i cancel the download i don't get any callback from DownloadManager to update the app UI.
This cancle option is only available in Android 7 .
Or else is there any option to hide or remove the cancel option from there.
After registering your broadcast receiver for DownloadManager.ACTION_DOWNLOAD_COMPLETE, you can check for DownloadManager status in the onReceive() method of the DownloadManager broadcast as follows -
private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
checkDownloadStatus();
}
};
private void checkDownloadStatus(){
// TODO Auto-generated method stub
DownloadManager.Query query = new DownloadManager.Query();
long id = preferenceManager.getLong(strPref_Download_ID, 0);
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = cursor.getInt(columnIndex);
int columnReason = cursor.getColumnIndex(DownloadManager.COLUMN_REASON);
int reason = cursor.getInt(columnReason);
switch(status){
case DownloadManager.STATUS_FAILED:
String failedReason = "";
switch(reason){
case DownloadManager.ERROR_CANNOT_RESUME:
failedReason = "ERROR_CANNOT_RESUME";
break;
case DownloadManager.ERROR_DEVICE_NOT_FOUND:
failedReason = "ERROR_DEVICE_NOT_FOUND";
break;
case DownloadManager.ERROR_FILE_ALREADY_EXISTS:
failedReason = "ERROR_FILE_ALREADY_EXISTS";
break;
case DownloadManager.ERROR_FILE_ERROR:
failedReason = "ERROR_FILE_ERROR";
break;
case DownloadManager.ERROR_HTTP_DATA_ERROR:
failedReason = "ERROR_HTTP_DATA_ERROR";
break;
case DownloadManager.ERROR_INSUFFICIENT_SPACE:
failedReason = "ERROR_INSUFFICIENT_SPACE";
break;
case DownloadManager.ERROR_TOO_MANY_REDIRECTS:
failedReason = "ERROR_TOO_MANY_REDIRECTS";
break;
case DownloadManager.ERROR_UNHANDLED_HTTP_CODE:
failedReason = "ERROR_UNHANDLED_HTTP_CODE";
break;
case DownloadManager.ERROR_UNKNOWN:
failedReason = "ERROR_UNKNOWN";
break;
}
Toast.makeText(AndroidDownloadManagerActivity.this,
"FAILED: " + failedReason,
Toast.LENGTH_LONG).show();
break;
case DownloadManager.STATUS_PAUSED:
String pausedReason = "";
switch(reason){
case DownloadManager.PAUSED_QUEUED_FOR_WIFI:
pausedReason = "PAUSED_QUEUED_FOR_WIFI";
break;
case DownloadManager.PAUSED_UNKNOWN:
pausedReason = "PAUSED_UNKNOWN";
break;
case DownloadManager.PAUSED_WAITING_FOR_NETWORK:
pausedReason = "PAUSED_WAITING_FOR_NETWORK";
break;
case DownloadManager.PAUSED_WAITING_TO_RETRY:
pausedReason = "PAUSED_WAITING_TO_RETRY";
break;
}
Toast.makeText(AndroidDownloadManagerActivity.this,

Toast.LENGTH_LONG).show();
break;
case DownloadManager.STATUS_PENDING:
Toast.makeText(AndroidDownloadManagerActivity.this,

downloadManager.remove(id);

Broadcast Receiver for cancel downloading in android

I have built app which download file from link using DownloadManager and show progress wheel while downloading. Once downloading is completed I send broadcast receiver to change progress wheel to downloaded icon.
Now facing an issue that if I cancel the downloading from notification tray I don't get any broadcast for this so the progress wheel does not stop.
Can anyone have idea how can I get broadcast for cancel downloading?
To get event of downloading process you need to register downloadManager to broadcast receiver.
IntentFilter filter = new IntentFilter(DownloadManager.ACTION_DOWNLOAD_COMPLETE);
mContext.registerReceiver(downloadReceiver, filter);
Here, Broadcast receiver is :
private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
checkDownloadStatus(intent.getLongExtra(DownloadManager.EXTRA_DOWNLOAD_ID, -1));
}
};
So when downloading cancels or successfully downloaded or any error, you will get status. Even you cancel from notification. You can check status by:
private void checkDownloadStatus(long downloadReference) {
DownloadManager.Query myDownloadQuery = new DownloadManager.Query();
myDownloadQuery.setFilterById(downloadReference);
//Query the download manager about downloads that have been requested.
Cursor cursor = downloadManager.query(myDownloadQuery);
if (cursor.moveToFirst()) {
//column for 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
String statusText = "";
String reasonText = "";
switch (status) {
case DownloadManager.STATUS_FAILED:
statusText = "STATUS_FAILED";
switch (reason) {
case DownloadManager.ERROR_CANNOT_RESUME:
reasonText = "ERROR_CANNOT_RESUME";
break;
case DownloadManager.ERROR_DEVICE_NOT_FOUND:
reasonText = "ERROR_DEVICE_NOT_FOUND";
break;
case DownloadManager.ERROR_FILE_ALREADY_EXISTS:
reasonText = "ERROR_FILE_ALREADY_EXISTS";
break;
case DownloadManager.ERROR_FILE_ERROR:
reasonText = "ERROR_FILE_ERROR";
break;
case DownloadManager.ERROR_HTTP_DATA_ERROR:
reasonText = "ERROR_HTTP_DATA_ERROR";
break;
case DownloadManager.ERROR_INSUFFICIENT_SPACE:
reasonText = "ERROR_INSUFFICIENT_SPACE";
break;
case DownloadManager.ERROR_TOO_MANY_REDIRECTS:
reasonText = "ERROR_TOO_MANY_REDIRECTS";
break;
case DownloadManager.ERROR_UNHANDLED_HTTP_CODE:
reasonText = "ERROR_UNHANDLED_HTTP_CODE";
break;
case DownloadManager.ERROR_UNKNOWN:
reasonText = "ERROR_UNKNOWN";
break;
}
break;
case DownloadManager.STATUS_PAUSED:
statusText = "STATUS_PAUSED";
switch (reason) {
case DownloadManager.PAUSED_QUEUED_FOR_WIFI:
reasonText = "PAUSED_QUEUED_FOR_WIFI";
break;
case DownloadManager.PAUSED_UNKNOWN:
reasonText = "PAUSED_UNKNOWN";
break;
case DownloadManager.PAUSED_WAITING_FOR_NETWORK:
reasonText = "PAUSED_WAITING_FOR_NETWORK";
break;
case DownloadManager.PAUSED_WAITING_TO_RETRY:
reasonText = "PAUSED_WAITING_TO_RETRY";
break;
}
break;
case DownloadManager.STATUS_PENDING:
statusText = "STATUS_PENDING";
break;
case DownloadManager.STATUS_RUNNING:
statusText = "STATUS_RUNNING";
break;
case DownloadManager.STATUS_SUCCESSFUL:
statusText = "STATUS_SUCCESSFUL";
break;
}
}
}
On error, you can stop your progressbar.

android Downoad Manager get STATUS_PENDING always

I don't know why but I get always STATUS_PENDING even if file is downloading and it must be STATUS_RUNNING.
If use an recursive method with runnable with delay, after couple seconds again and again on the same id I got the right status. Any ideas?
The code for obtaining status is:
public static void checkStatus(long downloadId) {
DownloadManager.Query query = new DownloadManager.Query();
Cursor cursor = manager.query(query.setFilterById(downloadId));
if(cursor.moveToFirst()){
int status = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS));
switch (status) {
case DownloadManager.STATUS_PENDING:
Log.d("status", "STATUS_PENDING");
//here you can set your TIMEOUT solution
break;
case DownloadManager.STATUS_PAUSED:
Log.d("status", "STATUS_PAUSED");
break;
case DownloadManager.STATUS_RUNNING:
Log.d("status", "STATUS_RUNNING");
break;
case DownloadManager.STATUS_SUCCESSFUL:
Log.d("status", "STATUS_SUCCESSFUL");
break;
case DownloadManager.STATUS_FAILED:
Log.d("status", "STATUS_FAILED");
break;
}
}
}

Why is this cursor empty?

I have for example button and when user click on it I want to find out the download history by DownloadManager, but problem is that my cursor is empty, it never goes to condition if(c.moveToFirst()), it always skip this condition.
DownloadManager downloadMgr = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterByStatus(DownloadManager.STATUS_FAILED|DownloadManager.STATUS_PENDING|DownloadManager.STATUS_RUNNING|DownloadManager.STATUS_SUCCESSFUL);
Cursor c = downloadMgr.query(query);
if(c==null) {
//
}
else {
if(c.moveToFirst()) {
int columnIndex = c.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = c.getInt(columnIndex);
if(status == DownloadManager.STATUS_RUNNING){
//do something
}
}
}
I also tried this code (by imran khan) but still same problem:
DownloadManager.Query query = null;
Cursor c = null;
DownloadManager downloadManager = null;
downloadManager = (DownloadManager)getSystemService(DOWNLOAD_SERVICE);
query = new DownloadManager.Query();
query.setFilterByStatus(DownloadManager.STATUS_FAILED|DownloadManager.STATUS_PENDING|DownloadManager.STATUS_RUNNING|DownloadManager.STATUS_SUCCESSFUL);
c = downloadManager.query(query);
if(c.moveToFirst()) {
int status = c.getInt(c.getColumnIndex(DownloadManager.COLUMN_STATUS));
switch(status) {
case DownloadManager.STATUS_PAUSED:
break;
case DownloadManager.STATUS_PENDING:
break;
case DownloadManager.STATUS_RUNNING:
break;
case DownloadManager.STATUS_SUCCESSFUL:
break;
case DownloadManager.STATUS_FAILED:
break;
}
}
