Android: Files: Unable to get file path from content URI when file is selected from RECENT section in file browser

I was trying to fetch file path from Uri given by data.data!! onActivityResult() method in android. When I selected the DCIM folder in File browser I was able to get the file path but when I selected the same file from RECENT section in file browser I was not getting the file path.
Code on Button click:
val intent = Intent();
intent.setType("image/*");
val mimeTypes: Array<String> = arrayOf("image/*", "application/pdf")
intent.putExtra(Intent.EXTRA_MIME_TYPES,mimeTypes)
intent.setAction(Intent.ACTION_OPEN_DOCUMENT);
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
startActivityForResult(Intent.createChooser(intent, "Select File"), 101);
Code on returning data from onActivityResult() method:
var selectedImagePathFB:String = ""
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == RESULT_OK) {
if (requestCode == 101) {
val selectedImageUri:Uri = data?.data!!
selectedImagePathFB = getPath(this#MyContactUsActivity,selectedImageUri);
//selectedImagePathFB = AppUtils().getRealPathFromURI(this#MyContactUsActivity,selectedImageUri)
val url: String = selectedImagePathFB
}
}
}
and getPath(Context,Uri) is common found code from stackoverflow by paulburke:
public static String getPath(final Context context, final Uri uri) {
// DocumentProvider
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT && DocumentsContract.isDocumentUri(context, uri)) {
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");

return Environment.getExternalStorageDirectory() + "/" + split[1];
// TODO handle non-primary volumes

I am testing on android Q device. Why is that when selecting file from RECENT section in file browser i am not getting any file path meanwhile selecting same file in STORAGE section is returning file path? And is there a workaround also for converting files like PDF or Images in Base64 string if not from file path?

According to your code there is no error. But you have to get Storage permission before getting files from Recent section. Read and Write permission are required.

Unable to pickup file from SDCARD in Oreo

I am New in Android, Working on one functionality in which I have to pick up a file from internal storage and SDCARD. I have implemented some code. With the help of below code, I am able to pick up or select a file from SDcard and internal storage in the Android pie version(9 API level 28) and Android Nougat version(7) but I am not able to get pdf file in from SDCARD in Android Oreo(8 api level 26) version and for Marshmallow it is unable to select file from internal as well as SDCARD. I am not able to figure out what is the problem. Same code working for one not working for another. There is any universal way to access files(pdf and images).Thanks in advance

how ca in get data from choosed file with Intent.CreateChooser(Intent, "Select Any File") as byte

I want when choosing non-type files(apk, exe, pdf, ...) with intent chooser then extract data chose the file as a byte array in OnActivityResult I have a lot of searches but I can't do this, please help me.
This is my pick button Code:
private void Pick_Click(object sender, EventArgs e)
{
Intent = new Intent();
Intent.SetType("*/*");
Intent.SetAction(Intent.ActionGetContent);
Intent chooser = Intent.CreateChooser(Intent, "Select Any File");
StartActivityForResult(chooser, 1);
}
Now how can I get the choosed file in OnActivityResult?

I have created a new app and test with pdf and image, it works properly. The main code is as follows:
static readonly int REQUEST_CHOOSER = 0x001;
static readonly int REQUEST_File = 0x002;
Intent intent = new Intent(Intent.ActionGetContent);
intent.SetType("*/*");
intent.AddCategory(Intent.CategoryOpenable);
StartActivityForResult(Intent.CreateChooser(intent, "Select ,Music"), REQUEST_CHOOSER);

var filePath = IOUtil.getPath(this, _uri);

Your code looks fine you just have to get runtime permissions from user. In Andorid 6.0 or later needs permission from user at runtime only declaring them manifest is not enough.
See here my earlier post about how to get runtime permissions.
Update:
private void showFileChooser() {
try {
// Intent i = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
// startActivityForResult(i, RESULT_LOAD_IMAGE);
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("file/*");
startActivityForResult(intent, RESULT_LOAD_IMAGE);
} catch (android.content.ActivityNotFoundException ex) {
Toast.makeText(getActivity(), "Please install a File Manager.",
Toast.LENGTH_SHORT).show();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data) {
//Uri selectedImage = data.getData();
txt_file_name_1.setText(data.getData().toString());
}
}

Android opening a file with ACTION_GET_CONTENT results into different Uri's

I am trying to open files by using Intent.ACTION_GET_CONTENT.
Dependent on the Android version/device brand the file browser opens and I get the following results:
Selecting a file from Downloads:
content://com.android.providers.downloads.documents/document/446
Selecting a file from Fotos:
content://media/external/images/media/309
Selecting a file from FileCommander:
file:///storage/emulated/0/DCIM/Camera/20141027_132114.jpg
I can open all these files except when I try to open a file from Downloads,, Audio , Afbeeldingen(Images)
It's likely I can't handle this kind of Uri: content://com.android.providers.downloads.documents/document/446
I have tried the following things:
Trying to open the file by new File(uri.getPath()). File.exists() returns false.
Trying to open/reach the file by getContext().getContentResolver().openInputStream(uri). Results into a FileNotFoundException
Trying to open the file with the following code:
public static String getRealPathFromURI_API19(Context context, Uri uri) {
Log.i("uri", uri.getPath());
String filePath = "";
if (uri.getScheme().equals("file")) {
return uri.getPath();
} else if (DocumentsContract.isDocumentUri(context, uri)) {
String wholeID = DocumentsContract.getDocumentId(uri);
Log.i("wholeID", wholeID);
// Split at colon, use second item in the array
String[] splits = wholeID.split(":");
if (splits.length == 2) {
String id = splits[1];
String[] column = {MediaStore.Images.Media.DATA};
// where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = context.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
column, sel, new String[]{id}, null);
int columnIndex = cursor.getColumnIndex(column[0]);
if (cursor.moveToFirst()) {
filePath = cursor.getString(columnIndex);
}
cursor.close();
}
} else {
filePath = AttachmentUtils.getPath(context, uri);
}
return filePath;
}
What am I doing wrong?
UPDATE:
I have noticed that the files that are listed in the screenshot that they are not physically existing in the storage.
The device I am using is a tablet from the company containing rubbish data. My colleague told me that this device once was connected with a different Google account. These files could be the files from the previous account which are not existing/reachable anymore.
My own conclusion about it is that I am encountering some bug in Android.
My bug report
Update 6 february 2017:
Android banned the file:// URI. Please consider to think about it.
Ban on file: Uri Scheme The biggest compatibility issue so far with
Android 7.0 is that the file: scheme for Uri values is banned, in
effect. If you attempt to pass a file: Uri in an Intent that is going
to another app — whether via an extra or as the “data” facet of the
Intent — you will crash with a FileUriExposedException exception. You
will face similar issues with putting file: Uri values on the
clipboard in ClipData . This is coming from an updated edition of
StrictMode . StrictMode.VmPolicy.Builder has a
penaltyDeathOnFileUriExposure() method that triggers the detection of
file: Uri values and the resulting FileUriExposedException exceptions.
And, it appears that this is pre-configured, much as how StrictMode is
pre-configured to apply penaltyDeathOnNetwork() (the source of your
NetworkOnMainThreadException crashes).

Use below code.This will work for sure.
public static String getPath(Context context, Uri uri) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
// DocumentProvider
if (DocumentsContract.isDocumentUri(context, uri)) {
// ExternalStorageProvider
if (isExternalStorageDocument(uri)) {
final String docId = DocumentsContract.getDocumentId(uri);
final String[] split = docId.split(":");
final String type = split[0];
if ("primary".equalsIgnoreCase(type)) {
return Environment.getExternalStorageDirectory() + "/" + split[1];
}
// TODO handle non-primary volumes
}
// DownloadsProvider
else if (isDownloadsDocument(uri)) {
final String id = DocumentsContract.getDocumentId(uri);
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)) {

return getDataColumn(context, contentUri, selection, selectionArgs);
}
}
}

if (isGooglePhotosUri(uri))

return getDataColumn(context, uri, null, null);

}
public static String getDataColumn(Context context, Uri uri, String selection, String[] selectionArgs) {

final String column = "_data";
final String[] projection = {column};
try {

if (cursor != null && cursor.moveToFirst()) {
final int index = cursor.getColumnIndexOrThrow(column);
return cursor.getString(index);
}
} finally {
if (cursor != null)
cursor.close();
}
return null;
}
public static boolean isExternalStorageDocument(Uri uri) {
return "com.android.externalstorage.documents".equals(uri.getAuthority());
}
/**
* #param uri The Uri to check.
* #return Whether the Uri authority is DownloadsProvider.
*/
public static boolean isDownloadsDocument(Uri uri) {
return "com.android.providers.downloads.documents".equals(uri.getAuthority());
}

*/
public static boolean isMediaDocument(Uri uri) {
return "com.android.providers.media.documents".equals(uri.getAuthority());
}
/**

* #return Whether the Uri authority is Google Photos.
*/
public static boolean isGooglePhotosUri(Uri uri) {
return "com.google.android.apps.photos.content".equals(uri.getAuthority());
}
Use the below code to browse the file in any format.
public void browseClick() {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("*/*");
intent.addCategory(Intent.CATEGORY_OPENABLE);
//intent.putExtra("browseCoa", itemToBrowse);
//Intent chooser = Intent.createChooser(intent, "Select a File to Upload");
try {
//startActivityForResult(chooser, FILE_SELECT_CODE);
startActivityForResult(Intent.createChooser(intent, "Select a File to Upload"),FILE_SELECT_CODE);
} catch (Exception ex) {
System.out.println("browseClick :"+ex);//android.content.ActivityNotFoundException ex
}
}
Then get that file path in the onActivityResult like below.
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == FILE_SELECT_CODE) {
if (resultCode == RESULT_OK) {
try {
Uri uri = data.getData();
if (filesize >= FILE_SIZE_LIMIT) {
Toast.makeText(this,"The selected file is too large. Selet a new file with size less than 2mb",Toast.LENGTH_LONG).show();
} else {
String mimeType = getContentResolver().getType(uri);
if (mimeType == null) {
String path = getPath(this, uri);
if (path == null) {
filename = FilenameUtils.getName(uri.toString());
} else {
File file = new File(path);
filename = file.getName();
}
} else {
Uri returnUri = data.getData();
Cursor returnCursor = getContentResolver().query(returnUri, null, null, null, null);
int nameIndex = returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME);
int sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE);
returnCursor.moveToFirst();
filename = returnCursor.getString(nameIndex);
String size = Long.toString(returnCursor.getLong(sizeIndex));
}
File fileSave = getExternalFilesDir(null);
String sourcePath = getExternalFilesDir(null).toString();
try {
copyFileStream(new File(sourcePath + "/" + filename), uri,this);
} catch (Exception e) {
e.printStackTrace();
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
private void copyFileStream(File dest, Uri uri, Context context)
throws IOException {
InputStream is = null;
OutputStream os = null;
try {
is = context.getContentResolver().openInputStream(uri);
os = new FileOutputStream(dest);
byte[] buffer = new byte[1024];
int length;
while ((length = is.read(buffer)) > 0) {
os.write(buffer, 0, length);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
is.close();
os.close();
}
}
After this you can open this file from your application external storage where you saved the file with appropriate action.

Pick any file using System File Picker:
val intent = Intent(Intent.ACTION_GET_CONTENT)
intent.type = "*/*"
startActivityForResult(intent, 1)
onActivityResult:
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == 1 && resultCode == Activity.RESULT_OK) {
data?.data?.let {
getFileFromUri(requireContext().contentResolver, uri, requireContext().cacheDir)
}
}
}
Get File:
private fun getFileFromUri(contentResolver: ContentResolver, uri: Uri, directory: File): File {
val file =
File.createTempFile("suffix", "prefix", directory)
file.outputStream().use {
contentResolver.openInputStream(uri)?.copyTo(it)
}
return file
}

There is a bug I just faced
final String docId = DocumentsContract.getDocumentId(uri);
return different URI (e.g: content://com.android.providers.downloads.documents/document/11
and sometime content://com.android.providers.downloads.documents/document/abc%aile.jpg in that case Long.valueOf(id) throws an exception to fix that
String id = DocumentsContract.getDocumentId(uri);
if (id.startsWith("raw:")) {
id = id.replaceFirst("raw:", "");
return id;
}
final Uri contentUri = ContentUris.withAppendedId(
Uri.parse("content://downloads/public_downloads"), Long.valueOf(id));
return getDataColumn(contentUri, null, null);
do this return the id, it worked for me
