I'm using Download Manger for download some multimedia files and categorize them. I'm also using Crashlytics and this is an error I frequently get it on different devices and versions of Android. I'm looking for your solutions/suggestion!

You can see my codes below:
private class DownloadClickListener implements View.OnClickListener {
@Override
public void onClick(View view) {
// Check if download manager available before request
if (!DownloadHelper.isDownloadManagerAvailable(getActivity())) {
// Build custom alert dialog
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setMessage(R.string.download_manager_disabled);
builder.setCancelable(false);
builder.setPositiveButton(R.string.ok, (dialog, which) -> {
dialog.dismiss();
});
// Create and display alert dialog
AlertDialog dialog = builder.create();
dialog.show();
return;
}
// Display short toast on download clicked
Toast.makeText(getActivity(), R.string.lesson_download_start, Toast.LENGTH_SHORT).show();
// Get attach from view tag
Attache attache = (Attache) view.getTag();
// Get lesson using lesson id
Lesson lesson = new Select().from(Lesson.class)
.where(Condition.column("id").is(attache.getLessonId()))
.querySingle();
// Set file name from url and attache name
Uri uri = Uri.parse(attache.getFile());
String fileName = attache.getName() + '.'
+ MimeTypeMap.getFileExtensionFromUrl(attache.getFile());
// Check if path directory not exist and create it
String filePath = Environment.getExternalStorageDirectory() + "/myapp/" + lesson.getTitle() + "/";
File path = new File(filePath);
if (!path.exists() || !path.isDirectory()) {
if (!path.mkdirs()) {
Timber.e("Could not create path directory.");
}
}
// Check if file exist and then delete it
File file = new File(filePath, fileName);
if (file.exists() && file.isFile()) {
if (file.delete()) {
Timber.v("%s just deleted.", fileName);
}
}
// Create download manager request using url
DownloadManager.Request request = new DownloadManager.Request(uri);
request.setTitle(attache.getName());
request.setDestinationInExternalPublicDir("/myapp/" + lesson.getTitle(), fileName);
// Using DownloadManager for download attache file
DownloadManager manager = (DownloadManager) getActivity().getSystemService(Context.DOWNLOAD_SERVICE);
manager.enqueue(request);
}
}

For those who are getting Error Unknown URI: content://downloads/public_downloads.
I managed to solve this by getting a hint given by @Commonsware in this answer. I found out the class FileUtils on GitHub.
Here InputStream methods are used to fetch file from Download directory.
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
if (id != null && id.startsWith("raw:")) {
return id.substring(4);
}
String[] contentUriPrefixesToTry = new String[]{
"content://downloads/public_downloads",
"content://downloads/my_downloads",
"content://downloads/all_downloads"
};
for (String contentUriPrefix : contentUriPrefixesToTry) {
Uri contentUri = ContentUris.withAppendedId(Uri.parse(contentUriPrefix), Long.valueOf(id));
try {
String path = getDataColumn(context, contentUri, null, null);
if (path != null) {
return path;
}
} catch (Exception e) {}
}
// path could not be retrieved using ContentResolver, therefore copy file to accessible cache using streams
String fileName = getFileName(context, uri);
File cacheDir = getDocumentCacheDir(context);
File file = generateFileName(fileName, cacheDir);
String destinationPath = null;
if (file != null) {
destinationPath = file.getAbsolutePath();
saveFileFromUri(context, uri, destinationPath);
}
return destinationPath;
}
I have encountered the exception java.lang.IllegalArgumentException: Unknown URI: content://downloads/public_downloads/7505 in getting the doucument from the downloads. This solution worked for me.
else if (isDownloadsDocument(uri)) {
String fileName = getFilePath(context, uri);
if (fileName != null) {
return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
}
String id = DocumentsContract.getDocumentId(uri);
if (id.startsWith("raw:")) {
id = id.replaceFirst("raw:", "");
File file = new File(id);
if (file.exists())
return id;
}
final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
This the method used to get the filepath
public static String getFilePath(Context context, Uri uri) {
Cursor cursor = null;
final String[] projection = {
MediaStore.MediaColumns.DISPLAY_NAME
};
try {
cursor = context.getContentResolver().query(uri, projection, null, null,
null);
if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DISPLAY_NAME);
return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
The exception is caused by disabled Download Manager. And there is no way to activate/deactivate Download Manager directly, since it's system application and we don't have access to it.
Only alternative way is redirect user to settings of Download Manager Application.
try {
//Open the specific App Info page:
Intent intent = new Intent(android.provider.Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
intent.setData(Uri.parse("package:" + "com.android.providers.downloads"));
startActivity(intent);
} catch ( ActivityNotFoundException e ) {
e.printStackTrace();
//Open the generic Apps page:
Intent intent = new Intent(android.provider.Settings.ACTION_MANAGE_APPLICATIONS_SETTINGS);
startActivity(intent);
}
I got the same issue and after a lot of time spent on the search I found the solution
Just change your method especially // DownloadsProvider part
getpath()
to
@SuppressLint("NewApi") public static String getPath(final Context context, final Uri uri) {
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat && DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
// This is for checking Main Memory
if ("primary".equalsIgnoreCase(type)) {
if (split.length > 1) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
} else {
return Environment.getExternalStorageDirectory() + "/";
}
// This is for checking SD Card
} else {
return "storage" + "/" + docId.replace(":", "/");
}
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
String fileName = getFilePath(context, uri);
if (fileName != null) {
return Environment.getExternalStorageDirectory().toString() + "/Download/" + fileName;
}
String id = DocumentsContract.getDocumentId(uri);
if (id.startsWith("raw:")) {
id = id.replaceFirst("raw:", "");
File file = new File(id);
if (file.exists())
return id;
}
final Uri contentUri = ContentUris.withAppendedId(Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(context, contentUri, null, null);
}
// MediaProvider
else if (isMediaDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
Uri contentUri = null;
if ("image".equals(type)) {
contentUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
} else if ("video".equals(type)) {
contentUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
} else if ("audio".equals(type)) {
contentUri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;
}
final String selection = "_id=?";
final String[] selectionArgs = new String[]{
split[1]
};
return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
// MediaStore (and general)
else if ("content".equalsIgnoreCase(uri.getScheme())) {
// Return the remote address
if (isGooglePhotosUri(uri))
return uri.getLastPathSegment();
return getDataColumn(context, uri, null, null);
}
// File
else if ("file".equalsIgnoreCase(uri.getScheme())) {
return uri.getPath();
}
return null;
