I want to save Image file in Gallery so that Image can be viewed from the Gallery application.
But what I want is to create a separate dir, as like we have for whatsapp Images etc apps in our gallery application.
So far I have written this code to download an image
public void createDir(){
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), DIR_NAME);
Log.d(LOG_TAG, "dir pictr :" + dir.toString());
if (!dir.exists()) {
dir.mkdir();
Log.d(LOG_TAG, "dir not exists and created first time");
} else {
Log.d(LOG_TAG, "dir exists");
}
}
Above code created directory inside gallery dir
Uri imageLink = Uri.parse(downloadUrlOfImage); // this is download link like www.com/abc.jpg
CreateDir();
DownloadManager.Request request = new DownloadManager.Request(imageLink);
File dir = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES), DIR_NAME);
String absPath = dir.getAbsoultePath();
request.setDestinationUri(Uri.parse(absPath + "image.jpg"));
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
DownloadManager dm = (DownloadManager) getContext().getSystemService(Context.DOWNLOAD_SERVICE);
dm.enqueue(request);
But this gives me error as java.lang.IllegalArgumentException: Not a file URI: /storage/sdcard0/Pictures/FreeWee/1458148582.jpg
Basically what I want is to save Image and that image must be shown in Gallery Application under Some directory I named.
If not understood please ask, so that I can improve my question.
How do I proceed further ?
As #RoyFalk pointed out you got 2 issues in your code.
So you can go with this code snippet
String filename = "filename.jpg";
String downloadUrlOfImage = "YOUR_LINK_THAT_POINTS_IMG_ON_WEBSITE";
File direct =
new File(Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES)
.getAbsolutePath() + "/" + DIR_NAME + "/");
if (!direct.exists()) {
direct.mkdir();
Log.d(LOG_TAG, "dir created for first time");
}
DownloadManager dm = (DownloadManager) getContext().getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(downloadUrlOfImage);
DownloadManager.Request request = new DownloadManager.Request(downloadUri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false)
.setTitle(filename)
.setMimeType("image/jpeg")
.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED)
.setDestinationInExternalPublicDir(Environment.DIRECTORY_PICTURES,
File.separator + DIR_NAME + File.separator + filename);
dm.enqueue(request);
And you will see Image inside the gallery application under your DIR_NAME.
Hope this will help you.

I am using download manager to download the file. The code for downloading the file is as follow.
private String DownloadData(Uri uri, View v, String textview) {
long downloadReference;
// Create request for android download manager
dm = (DownloadManager)getContext().getSystemService(DOWNLOAD_SERVICE);
DownloadManager.Request request = new DownloadManager.Request(uri);
//Setting title of request
request.setTitle(textview);
//Setting description of request
request.setDescription("Android Data download using DownloadManager.");
//Set the local destination for the downloaded file to a path within the application's external files directory
request.setDestinationInExternalFilesDir(getContext(), DIRECTORY_DOWNLOADS, File.separator + "Dr_Israr_Ahmad" + File.separator + textview+".mp3");
//Enqueue download and save into referenceId
downloadReference = dm.enqueue(request);
return null
}
The above code works fine. What i need to do now is if the file is already downloaded than i want my app to play it. The code which is used is
String path = String.valueOf(getContext().getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS+ File.separator+"Dr_Israr_Ahmad" + File.separator +filename+".mp3"));
File file = new File(path);
if(file.exists()){
Toast.makeText(getContext(),path+ "/n exists", Toast.LENGTH_SHORT).show();
} else if (!file.exists()) {
Toast.makeText(getContext(), "Downloading", Toast.LENGTH_SHORT).show();
Uri uri = Uri.parse("http://www.digitalsguide.com/mobile-apps/dr-israr-ahmad/audios/"+filename+".mp3");
String filepath = DownloadData(uri,view,filename);
}
but the problem is the condition is true even if the file doesn't exist. Is there a problem in my path ? kindly help me out,
I detected some strange behavior with exists time ago and changed it to isFile:
File file = new File(path);
if (file.isFile()) {
Toast.makeText(getContext(), path + "/n exists", Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(getContext(), "Downloading", Toast.LENGTH_SHORT).show();
// ...
}
I think the mobile, somehow, created a directory every time new File() was executed.
Check this.
Because getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS) returns /storage/emulated/0/Android/data/<PACKAGE_ID>/files/Download. It's not the folder where DownloadManager downloads files when we set Environment.DIRECTORY_DOWNLOADS.
Try to put your path like the example shown below:
File file = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+ "/" +filename);
Here filename is example.pdf
you can then check if file exists or not
.getExternalFilesDir(yourFilePath) creates a directory in your code. so use it like this.
String path = String.valueOf(getContext().getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS)+ File.separator+"Dr_Israr_Ahmad" + File.separator +filename+".mp3");
I have downloaded some files with DownloadManager, I want to save them where that no one can access them, I mean they are private, just my application can access them and I want after uninstall my app they get deleted. but according to my search DownloadManager can save files just in SDCard that everyone can see my files.
can anyone tell me what to do?
You should probably use:
request.setDestinationInExternalFilesDir(context, DIRECTORY_DOWNLOADS, File.separator + folderName + File.separator + fileName);
Where request is your DownloadManager.Request
This folder (sdcard/Android/data/your.app.package) is accessible to the user, but not visible in galleries (not scanned by media scanner), it's only accessible using file manager. Also, this folder will be deleted when your app gets deleted.
You can use internal storage path to save data internally and it will get deleted when your app will get uninstalled
String dir = getFilesDir().getAbsolutePath();
For Set Your Path For Download File Use: Work For me (Android 11).
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/YOUR FOLDER/", "YOUR FILE.(mp3|mp4|pdf|...)");
request.setDestinationUri(Uri.fromFile(file));
Complete Code:
First Check Directory
private boolean CreateDirectory() {
boolean ret = false;
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getPath() + "/YOUR FOLDER/");
if (!dir.exists()) {
try {
dir.mkdirs();
ret = true;
} catch (Exception e) {
ret = false;
e.printStackTrace();
}
}
return ret;
}
Then:
String URL = " YOUR URL ";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(URL));
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setTitle("YOUR TITLE");
request.setDescription("YOUR DESCRIPTION");
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/YOUR FOLDER/", "YOUR FILE.(mp3|mp4|pdf|...)");
request.setDestinationUri(Uri.fromFile(file));
DownloadManager manager=(DownloadManager)getSystemService(Context.DOWNLOAD_SERVICE);
Long downloadId= manager.enqueue(request);
ok,Finish
how to save image or mp3 file in internal storage using Download manager
Code:

i m trying to store downloaded image or mp3 file in my internal storage
but it not work well
required path is "data/data/packagename/app_channel1/image1.jpg"
I am using download manager to download MP3 Files from my server.
Here is the code for it.
public String createFilePath()
{
String path;
String dir = "APP_NAME";
path = Environment.getExternalStorageDirectory().getPath();
File file = new File(Environment.getExternalStorageDirectory(),dir);
if(!file.exists())
{
file.mkdir();
}
path += "/" +dir + "/";
System.out.println("-- saving path : " + path);
return path;
}
public void startDownload() {
Uri uri=Uri.parse(URLFixer.Fix(DATA.url));
System.out.println("-- download path : " + createFilePath() + FileNameGetter.getFileName(DATA..url));
DownloadManager.Request request = new Request(uri);
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI |DownloadManager.Request.NETWORK_MOBILE);
request.setAllowedOverRoaming(false);
request.setTitle(DATA..title);
request.setDescription(DATA.artist + " - " + DATA.album);
request.setDestinationInExternalFilesDir(activity, createFilePath(), FileNameGetter.getFileName(DATA..url));
// request.setNotificationVisibility(Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.HONEYCOMB) {
// request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN);
request.setNotificationVisibility(Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
lastDownload= mgr.enqueue(request);
isDownloading = true;
Toasts.pop(activity, "Download Started!!");
// v.setEnabled(false);
// findViewById(R.id.query).setEnabled(true);
}
The problem is that it should be saved on SD Card inside folder "APP_NAME", but once the audio is downloaded, I cant see it inside that folder, and when I play the audio, and check its info, it shows path like thie
/sdcard/Android/data/com.X.app/files/mnt/sdcard/APP_NAME/file.mp3
As its being saved inside data folder, user is not able to see the file. How to fix it to move it to main SD Card i.e. /mnt/sdcard/APP_NAME so that user can see it.
DownloadManager.Request.setDestinationUri(Uri uri) should fit your requirement, remember to call allowScanningByMediaScanner() if you want the MP3 to be scanned by MediaScanner.
I've a question about Download Manager.
I'm going to download a file from a site. When I set the default directory for download (Environment.DIRECTORY_DOWNLOAD) all works fine and my download is started. But if I try to change the directory, my app doesn't download the file. In particular, I want my file to go into a folder inside a Download, for example /storage/sdcard/Download/myFolder. How can I fix that?
File mydownload = new File (Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS)+ "/myFolder");
if (!mydownload.exists()){
mydownload.mkdir();
}
String url = sUrl[0];
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url));
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
}
request.setDestinationInExternalPublicDir(mydownload.getAbsolutePath(),"Myfile.extension");
DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
check below code: its save file in "sdcard/dhaval_files/". just replace your folder name and give permission write_external_storage in android manifest file.
public void file_download(String uRl) {
File direct = new File(Environment.getExternalStorageDirectory()
+ "/dhaval_files");
if (!direct.exists()) {
direct.mkdirs();
}
DownloadManager mgr = (DownloadManager) this.getSystemService(Context.DOWNLOAD_SERVICE);
Uri downloadUri = Uri.parse(uRl);
DownloadManager.Request request = new DownloadManager.Request(
downloadUri);
request.setAllowedNetworkTypes(
DownloadManager.Request.NETWORK_WIFI
| DownloadManager.Request.NETWORK_MOBILE)
.setAllowedOverRoaming(false).setTitle("Demo")
.setDescription("Something useful. No, really.")
.setDestinationInExternalPublicDir("/dhaval_files", "test.jpg");
mgr.enqueue(request);
}
There are two options available for you to use.
1) first setDestinationInExternalPublicDir this will let you download in any of the androids standard download folder based on media type eg DIRECTORY_DOWNLOADS, DIRECTORY_MUSIC. these files will remain after uninstall.
request.setDestinationInExternalPublicDir(DIRECTORY_DOWNLOADS,
File.separator + folderName + File.separator + fileName);
The first argument should be a standard downloads directory for this to work properly and cannot be anything else.
2) second is setDestinationInExternalFilesDir this is same as the previous method with the difference that these files will be deleted after app uninstall.
request.setDestinationInExternalFilesDir(context, DIRECTORY_DOWNLOADS,
File.separator + folderName + File.separator + fileName);
here the second argument can be null or any of the android download directories.
Try Below Code:.
String storagePath = Environment.getExternalStorageDirectory()
.getPath()
+ "/Directory_name/";
//Log.d("Strorgae in view",""+storagePath);
File f = new File(storagePath);
if (!f.exists()) {
f.mkdirs();
}
//storagePath.mkdirs();
String pathname = f.toString();
if (!f.exists()) {
f.mkdirs();
}
// Log.d("Storage ",""+pathname);
dm = (DownloadManager) getSystemService(DOWNLOAD_SERVICE);
Uri uri = Uri.parse(image);
checkImage(uri.getLastPathSegment());
if (!downloaded) {
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
request.setDestinationInExternalPublicDir("/Directory_name", uri.getLastPathSegment());
Long referese = dm.enqueue(request);
Toast.makeText(getApplicationContext(), "Downloading...", Toast.LENGTH_SHORT).show();
}
For Set Your Path For Download File Use: Work For me (Android 11).
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/YOUR FOLDER/", "YOUR FILE.(mp3|mp4|pdf|...)");
request.setDestinationUri(Uri.fromFile(file));
Complete Code:
First Check Directory
private boolean CreateDirectory() {
boolean ret = false;
File filepath = Environment.getExternalStorageDirectory();
File dir = new File(filepath.getPath() + "/YOUR FOLDER/");
if (!dir.exists()) {
try {
dir.mkdirs();
ret = true;
} catch (Exception e) {
ret = false;
e.printStackTrace();
}
}
return ret;
}
Then:
String URL = " YOUR URL ";
DownloadManager.Request request = new DownloadManager.Request(Uri.parse(URL));
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI | DownloadManager.Request.NETWORK_MOBILE);
request.setTitle("YOUR TITLE");
request.setDescription("YOUR DESCRIPTION");
request.allowScanningByMediaScanner();
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED);
File file = new File(Environment.getExternalStorageDirectory().getPath() + "/YOUR FOLDER/", "YOUR FILE.(mp3|mp4|pdf|...)");
request.setDestinationUri(Uri.fromFile(file));
DownloadManager manager= (DownloadManager)
getSystemService(Context.DOWNLOAD_SERVICE);
Long downloadId= manager.enqueue(request);
