When I use Environment.getExternalStorageDirectory()+File.separator+"applicationAsbid"; I expect to create a directory in device's external storage but it is created in Cache folder.
Why?
What happened and what should I do?
UPDATE:
This is my method:
root = Environment.getExternalStorageDirectory().getPath();
myDir = new File(root);
myDir.mkdir();
private void downloadDoc(ProgressBar progressBar, CircularImageView imageView, String name, String link, SendMessageViewModel messageData) {
progressBar.setVisibility(View.VISIBLE);
Uri uri = Uri.parse(link);
DownloadManager downloadManager = (DownloadManager) mContext.getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle("در حال دانلود");
request.setDescription("لطفا منتظر بمانید...");
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_MOBILE | DownloadManager.Request.NETWORK_WIFI);
request.setDestinationInExternalFilesDir(mContext, root, name);
final long id = downloadManager.enqueue(request);
Timer timer = new Timer();
timer.schedule(new TimerTask() {
#Override
public void run() {
DownloadManager.Query query = new DownloadManager.Query();
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if (cursor.moveToFirst()) {
long downloadedBytes = cursor.getLong(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
long totalBytes = cursor.getLong(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
final int status = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS));
final int percent = (int) ((downloadedBytes * 100) / totalBytes);
((Activity) mContext).runOnUiThread(new Runnable() {
#Override
public void run() {
progressBar.setProgress(percent);
if (percent == 100) {
Toast.makeText(mContext, "دانلود با موفقیت انجام شد", Toast.LENGTH_SHORT).show();
timer.purge();
timer.cancel();
for (int item : downloadList) {
if (Integer.parseInt(messageData.getId()) == item) {
imageView.setImageResource(R.drawable.ic_doc3);
imageView.setContentDescription("after");
progressBar.setVisibility(View.GONE);
}
}
}
}
});
}
}
}, 0, 100);
}
At the end I should say this is not my own code and my colleague has written that. We check that and found nothing so I aske here.
We use Downloadmanager in another class and for download something else. That works fine but here it does not work.
Second Update:
I changed my code to this:
root = Environment.getExternalStorageDirectory().getPath() + "/Dehkade/Chat1";
myDir = new File(root);
if (!myDir.exists()) {
if (!myDir.mkdir()) {
Toast.makeText(mContext," ...sorry could not create directory...",Toast.LENGTH_SHORT).show();
return;
}
}
But it does not work too, in fact the Toast is executed. Also I use this code:
request.setDestinationInExternalFilesDir(mContext, null, name);
Instead of this code:
request.setDestinationInExternalFilesDir(mContext, root, name);
But nothing changes.

I have a list of PDFs that I need to download all PDFs in one click. I have implemented a foreground service to do the task. In this service I am enqueuing the list of PDFs in the Android DownloadManager's request to handle the downloads.
For the enqueue of request, I am inserting 6 PDF's in request for the first time and further when any one download completed I am inserting next PDF in the request list.
In this implementation the whole process is taking around 1-2 mins for the 91 PDFs(roughly size of 40MB in total). Is there any way, so we can speed up the download process.
This is the function to start Download queue
private void startDownloadQueue()
{
for(int i=0;i<6;i++){
if(i<hashMap.size()) {
listIndex++;
initiateDownload(documentList.get(i), positionList.get(i), hashMap.size());
}
}
}
private void initiateDownload(DocumentJsonModel.Document doc, int pos, int listSize)
{
if (doc != null && isDownloading) {
String position = String.valueOf(pos);
String docId = doc.id;
String docFile = doc.file;
String docName = doc.name;
String docDescription = doc.description;
boolean isJustView = false;
isFromSearch = false;
long id = downloadFile(doc, docId, docFile, docName, docDescription, position, isJustView, listSize);
if (id != 0) {
setProgressUpdate(id, Integer.parseInt(position), Integer.parseInt(docId), isJustView, doc, listSize);
} else if (isJustView) {
Intent intent1 = new Intent(INTENT_FILTER_ACTION_OPEN_DOC);
intent1.putExtra("docID",docId);
intent1.putExtra("position",pos);
intent1.putExtra("fromDownloadAll", true);
intent1.putExtra("docId", docId);
sendBroadcast(intent1);
stopForeground(true);
stopSelf();
} else if (isFromSearch) {
Intent intent1 = new Intent(INTENT_FILTER_ACTION_OPEN_DOC_FROM_SEARCH);
intent1.putExtra("fromDownloadAll", true);
intent1.putExtra("position", pos);
intent1.putExtra("docId", docId);
sendBroadcast(intent1);
stopForeground(true);
stopSelf();
}
}
}
Method to enqueue PDFs in download manager request queue -
public long downloadFile(DocumentJsonModel.Document doc,String docId, String docFile, String docName, String description, String position, boolean isJustView, int listSize) {
long downloadReference = 0;
String root = "/twoway/saved_documents/";
String BASE_DIR = getExternalFilesDir(null).getPath();
File dir = new File(BASE_DIR + root);
File file = new File(dir, docId + "_" + docFile);
if(!isCancelledButtonPressed) {
if (!file.exists()) {
String fileUrl = DOCUMENT_URL + docFile;
fileUrl = fileUrl.replaceAll(" ", "%20");
Uri fileUri = Uri.parse(fileUrl);
//Create request for android download manager
DownloadManager downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(fileUri);
//set title for download
request.setTitle(docName);
request.setVisibleInDownloadsUi(false);
//request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_ONLY_COMPLETION);
//Setting description of request
request.setDescription(description);
request.setDestinationInExternalFilesDir(this, null, "/twoway/saved_documents/"
+ docId + "_" + docFile);
//Enqueue download and save into referenceId
downloadReference = downloadManager.enqueue(request);
}
}}
I know there are some libraries for this, but i want to implement my own pause/resume functionality for android.

how can i implement Pause/Resume for my downloads? WITHOUT a library?
is it possible trough Download manager itself or i should use some other methods?
You can send message to the DownloadService you created, and invoke the DownloadManager to do the pause and resume action.
When DownloadManager enqueue a download task, you will get a id (long)
DownloadManager keep the download info in the ContentProvider, just update the ContentProvider info with the given id (long), if the network or other conditions satisfied the action will execute.
You can extends DownloadManager and create a pair of methods like below.
Pause Download
/**
* pause download
*
* #param ids the IDs of the downloads to be paused
* #return the number of downloads actually paused
*/
public int pauseDownload(long... ids) {
if (ids == null || ids.length == 0) {
// called with nothing to remove!
throw new IllegalArgumentException("input param 'ids' can't be null");
}
ContentValues values = new ContentValues();
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_PAUSED);
values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_PAUSED_BY_APP);
if (ids.length == 1) {
return mResolver.update(ContentUris.withAppendedId(mBaseUri, ids[0]), values,
null, null);
}
return mResolver.update(mBaseUri, values, getWhereClauseForIds(ids),
getWhereArgsForIds(ids));
}
Resume download
/**
* resume download
*
* #param ids the IDs of the downloads to be resumed
* #return the number of downloads actually resumed
*/
public int resumeDownload(long... ids) {
if (ids == null || ids.length == 0) {
// called with nothing to remove!
throw new IllegalArgumentException("input param 'ids' can't be null");
}
ContentValues values = new ContentValues();
values.put(Downloads.Impl.COLUMN_CONTROL, Downloads.Impl.CONTROL_RUN);
values.put(Downloads.Impl.COLUMN_STATUS, Downloads.Impl.STATUS_RUNNING);
if (ids.length == 1) {
return mResolver.update(ContentUris.withAppendedId(mBaseUri, ids[0]), values,
null, null);
}
return mResolver.update(mBaseUri, values, getWhereClauseForIds(ids),
getWhereArgsForIds(ids));
}
I am trying to cancel downloading task with id.
I get id from
DownloadManager manager = (DownloadManager) getApplicationContext().getSystemService(Context.DOWNLOAD_SERVICE);
downloadId = manager.enqueue(req);
I want to stop download when on user button click, but I tested to stop download after 10% of being downloaded in this test code.
the code "manager.remove(downloadId);" is working perfect to clear downloading noti and stopping the task with requested ID. But it also stop the app too, app error also occur after that code. please how can I solve the problem.
new Thread(new Runnable() {

Logcat Output
Please Kindly help me. Thank you in advance.
Try this
if (cursor.getCount() > 0)
manager.remove(downloadId); ///// Stop after 10%
I'm trying to show the download progress of DownloadManager in percentage as shown in the notification bar.
I've read up some answer here.
However, the method provided is using the Thread.
As my understanding,Thread is not a good way.
Is there any alternative way to do the same thing?
Or using Thread is just fine in this case?
Edit 1:
Added in the code in my project.
new Thread(new Runnable() {
#Override
public void run() {
boolean downloading = true;
while (downloading) {
DownloadManager.Query q = new DownloadManager.Query();
q.setFilterById(downloadId);
Cursor cursor = downloadManager.query(q);
cursor.moveToFirst();
int bytes_downloaded = cursor.getInt(cursor
.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
int bytes_total = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
if (cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_STATUS)) == DownloadManager.STATUS_SUCCESSFUL) {
downloading = false;
}
final int dl_progress = (int) ((bytes_downloaded * 100l) / bytes_total);
((Activity) mContext).runOnUiThread(new Runnable() {
#Override

}
});
cursor.close();

I am using .net web services and I am able to download the file in sd card, But I want to show progress bar when particular file start download and complete and then I want to show options like view and cancel.

Please suggest how to use download manager into it??? thanks
You could use a ProgressBar to accomplish this.
First, add a progressbar to your interface like this:
<ProgressBar
android:id="#+id/progress_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#android:style/Widget.ProgressBar.Small"/>
Then in your code update your method like this:
protected ProgressBar mProgressBar;
protected long downloadId;
protected DownloadManager manager;
public void startdownload() {
//<SET UP DOWNLOAD MANAGER HERE>
downloadId = manager.enqueue(request);
mProgressBar = findViewById(R.id.progress_bar);
Timer myTimer = new Timer();
myTimer.schedule(new TimerTask() {
#Override
public void run() {
DownloadManager.Query q = new DownloadManager.Query();
q.setFilterById(downloadId);
Cursor cursor = manager.query(q);
cursor.moveToFirst();
int bytes_downloaded = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));
int bytes_total = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_TOTAL_SIZE_BYTES));
cursor.close();
int dl_progress = (bytesDownloaded * 1f / bytesTotal) * 100;
runOnUiThread(new Runnable(){
#Override
public void run(){
mProgressbar.setProgress((int) dl_progress);
}
});
}
}, 0, 10);
}
Use Follow Method
private NotificationManager mNotifyManager;
case R.id.btnSubmit:
mNotifyManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
mBuilder = new NotificationCompat.Builder(context);
mBuilder.setContentTitle("BuyMixTapes")
.setContentText("Download in progress")
.setSmallIcon(R.drawable.appiconmain);
new DownloadFile().execute(vv);
public class DownloadFile extends AsyncTask<String, String, String> {
/**
* Before starting background thread
* Show Progress Bar Dialog
*/
#Override
protected void onPreExecute() {
super.onPreExecute();
//context.showDialog(progress_bar_type);
mBuilder.setProgress(100, 0, false);
mNotifyManager.notify(id, mBuilder.build());
}
protected String doInBackground(String... f_url) {
int count;
try {
for (int i = 0; i < f_url.length; i++) {
Log.e("0url",""+f_url[0]);
Log.e("1url",""+f_url[1]);
// Log.e("1url",""+f_url[1]);
URL url = new URL(f_url[i]);
URLConnection conection = url.openConnection();
conection.connect();
// getting file length
int lenghtOfFile = conection.getContentLength();
// input stream to read file - with 8k buffer
InputStream input = new BufferedInputStream(url.openStream(), 8192);
// Output stream to write file
// OutputStream output = new FileOutputStream("/sdcard/"+f_url[i]);
OutputStream output = new FileOutputStream(
"/sdcard/" +i + "buymix.mp3");
byte data[] = new byte[1024];
long total = 0;
while ((count = input.read(data)) != -1) {
total += count;
// publishing the progress....
// After this onProgressUpdate will be called
publishProgress("" + (int) ((total * 100) / lenghtOfFile));
// writing data to file
output.write(data, 0, count);
}
// flushing output
output.flush();
// closing streams
output.close();
input.close();
}
} catch (Exception e) {
Log.e("Error: ", e.getMessage());
}
return null;
}
/**
* Updating progress bar
*/
/**
* After completing background task
* Dismiss the progress dialog
**/
#Override
protected void onProgressUpdate(String... values) {
// Update progress
mBuilder.setProgress(100, Integer.parseInt(values[0]), false);
mNotifyManager.notify(id, mBuilder.build());
super.onProgressUpdate(values);
}
protected void onPostExecute(String result) {
super.onPostExecute(result);
mBuilder.setContentText("Download complete");
// Removes the progress bar
String imagePath = Environment.getExternalStorageDirectory()
.toString() + "/downloaded.mp3";
mBuilder.setProgress(0, 0, false);
mNotifyManager.notify(id, mBuilder.build());
}
}
Update 2021:
Add a ProgressBar in your layout (TextView is just for showing more information):
<ProgressBar
android:id="#+id/progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/progressBar"
android:text="Hello World!" />
Then before onCreate:
DownloadManager downloadManager;
long downloadReference;
TextView text1;
ProgressBar progressBar;
Timer progressTimer;
Afterwards, in onCreate:
text1 = (TextView) findViewById(R.id.textView1);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
Then after setting up download manager:
// <Some codes which setup download manager>
downloadReference = downloadManager.enqueue(request); // enqueue a new download
// update progressbar
progressTimer = new Timer();
progressTimer.schedule(new TimerTask() {
#Override
public void run() {
DownloadManager.Query downloadQuery = new DownloadManager.Query();
downloadQuery.setFilterById(downloadReference);
Cursor cursor = downloadManager.query(downloadQuery);
if (cursor.moveToFirst()) { // this "if" is crucial to prevent a kind of error
final int downloadedBytes = cursor.getInt(cursor.getColumnIndex(DownloadManager.COLUMN_BYTES_DOWNLOADED_SO_FAR));

Some tips:
If your file is larger than 2GB, you should use another type instead of int such as double etc.
You can stop timer somewhere else for example, in BroadcastReceiver if you have.
Task executions is every 1000 milliseconds (every 1 second) which is obviously changable.
