Is there a way to detect when the system starts a download and get information of it and force to download it to specific location? I googled it and results where not much helpful
Start this service class and then start your download it will print the result for status of download.
public class MyService extends Service {
private Timer timer;

timerTask = new TimerTask() {
#Override
public void run() {
// Log.d(MyService.class.toString(),
// "tic ... "+System.currentTimeMillis());
getDownloadData();
}
};
if (timer != null && timerTask != null) {
timer.schedule(timerTask, 0, SAMPLING_RATE);
}

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:

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_UNHANDLED_HTTP_CODE:

break;

I am using Android Download Manager class to download file from web. The Download Manager doesn't display error by default when there is not insufficient storage. I know how to check for current storage available and compare it with current file size before downloading it with following code:
public boolean isSpaceAvailable(long bytes) {
StatFs stat = new StatFs(Environment.getExternalStorageDirectory().getPath());
long bytesAvailable = (long) stat.getBlockSize() * (long) stat.getBlockCount();
return true;
}
But I would like to use ERROR_INSUFFICIENT_SPACE instead. How can I use this?
Android DownloadManager
I found the solution. I have Cursor to check if it moves to first and then check for `COLUMN_STATUS':
private void checkStatus(Cursor cursor){
//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
int filenameIndex = cursor.getColumnIndex(DownloadManager.COLUMN_LOCAL_FILENAME);
String filename = cursor.getString(filenameIndex);
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";
reasonText = "Filename:\n" + filename;
break;
}
Log.d("Error", statusText + " " + reasonText);
}
And then calling the method:
if(cursor.moveToFirst()) checkStatus(cursor);

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.

P.S.: Sorry for my bad language.
If you want to directly type into the EditText you are missing the following in your method:
display.requestFocus();
EDIT
This is the method I am using to show the keyboard with focus, the different focus call could do the trick.
protected void showKeyboard(EditText edit) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(edit, 0);
edit.requestFocusFromTouch();
}
