How do I download a specific file from the FirebaseStorage using its downloadURL?
I load the image, pdf, and text file into a RecyclerView. When I tap on a CardView (in the RecyclerView) I will be redirected to the file's corresponding download url in a browser. How should I do it so that instead of opening it in a web browser, the file would be downloaded to a specific folder in the user's phone.
Any help is appreciated. Thanks!
To download any file from Url you can simply use the Download Manager of Android this is code to download file from URL
String[] PERMISSIONS = { android.Manifest.permission.WRITE_EXTERNAL_STORAGE, android.Manifest.permission.READ_EXTERNAL_STORAGE, }; if (!hasPermissions(activity.this, PERMISSIONS)) { String url = "https://firebasestorage.googleapis.com/v0/b/smart-edubox-90c5d.appspot.com/o/uploaded_files%2Fpdf_files%2F08-11-2022_15%3A43%3A02_dummy.pdf?alt=media&token=f68e7403-0cb7-4c86-9799-1c47fffd9cb5"; DownloadManager.Request request = new DownloadManager.Request(Uri.parse(url)); request.setDescription("Some descrition"); request.setTitle("Some title"); // in order for this if to run, you must use the android 3.2 to compile your app request.allowScanningByMediaScanner(); request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); request.setDestinationInExternalPublicDir(Environment.DIRECTORY_DOWNLOADS, "name-of-the-file.pdf"); // get download service and enqueue file DownloadManager manager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE); manager.enqueue(request); } this is permission for Storage
public static boolean hasPermissions(Context context, String... permissions) { if (context != null && permissions != null) { for (String permission : permissions) { if (ActivityCompat.checkSelfPermission(context, permission) != PackageManager.PERMISSION_GRANTED) { return false; } } } return true; } and your manifest permissions will be
<uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> <uses-permission android:name="android.permission.WAKE_LOCK" /> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
