Question

I create an app that fetch all pdf documents from Phone storage... But in Android 10 devices , all pdfs not retrieved ... and even when I shall be tried to rename the pdf file , the pdf file is gone...
this is my code :
#NonNull
public ArrayList getAllPdfs(#NonNull Context context1) {
String str = null;
Uri collection;
ArrayList<PdfModel> arrayList = new ArrayList<>();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
collection = MediaStore.Files.getContentUri(MediaStore.VOLUME_EXTERNAL);
} else {
collection = MediaStore.Files.getContentUri("external");
}
// collection = MediaStore.Files.getContentUri("external");
try {
final String[] projection = new String[]{
MediaStore.Files.FileColumns._ID,
MediaStore.Files.FileColumns.DISPLAY_NAME,
MediaStore.Files.FileColumns.DATE_ADDED,
MediaStore.Files.FileColumns.DATA,
MediaStore.Files.FileColumns.MIME_TYPE,
};
Context context = getActivity();
SharedPreferences save_preferences = homeContext.getSharedPreferences(MY_SORT_PREF,
MODE_PRIVATE);
SharedPreferences preferencesOrder = homeContext.getSharedPreferences("Order", MODE_PRIVATE);
String order_by_descending = preferencesOrder.getString("order", "descending");
String order = null;
switch (order_by_descending) {
case "descending":
String sort = save_preferences.getString("sorting", "SortByDate");
switch (sort) {
case "SortByName":
order = MediaStore.Files.FileColumns.DISPLAY_NAME + " DESC";
break;
case "SortByDate":
order = MediaStore.Files.FileColumns.DATE_ADDED + " DESC";
break;
case "SortBySize":
order = MediaStore.Files.FileColumns.SIZE + " DESC";
break;
}
break;
case "ascending":
String sort_date = save_preferences.getString("sorting", "SortByDate");
switch (sort_date) {
case "SortByName":
order = MediaStore.Files.FileColumns.DISPLAY_NAME + " ASC";
break;
case "SortByDate":
order = MediaStore.Files.FileColumns.DATE_ADDED + " ASC";
break;
case "SortBySize":
order = MediaStore.Files.FileColumns.SIZE + " ASC";
break;
}
break;
}
final String selection = MediaStore.Files.FileColumns.MIME_TYPE + " = ?";
final String mimeType = MimeTypeMap.getSingleton().getMimeTypeFromExtension("pdf");
final String[] selectionArgs = new String[]{mimeType};
CursorLoader cursorLoader = new CursorLoader(context1, collection, projection, selection,
selectionArgs, order);
Cursor cursor = cursorLoader.loadInBackground();
if (cursor != null && cursor.moveToFirst()) {
do {
int columnName = cursor.getColumnIndex(MediaStore.Files.FileColumns.DISPLAY_NAME);
int columnData = cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA);
String path = cursor.getString(columnData);
if (new File(path).exists()) {
#SuppressLint("Range")
File file = new
File(cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns.DATA)));
if (file.exists()) {
Log.d(TAG, "getAllPdfs: a " + file.length());
PdfModel pdfModel = new PdfModel();
//------------------------------Remove (.pdf) extension------------------------
String fileName = file.getName();
if (fileName.indexOf(".") > 0)
fileName = fileName.substring(0, fileName.lastIndexOf("."));
Uri imageUri = Uri.fromFile(file.getAbsoluteFile());
Log.d(TAG, "getAllPdfs: bb " + file.getName());
pdfModel.setId(file.getName());
pdfModel.setName(removeExtension(file.getName()));
pdfModel.setAbsolutePath(file.getAbsolutePath());
pdfModel.setParentFilePath(Objects.requireNonNull(file.getParentFile()).getName());
pdfModel.setPdfUri(file.toString());
pdfModel.setLength(file.length());
pdfModel.setLastModified(file.lastModified());
//pdfModel.setThumbNailUri(file.);
arrayList.add(pdfModel);
} else {
Log.d(TAG, "getAllPdfs: ");
}
}
} while (cursor.moveToNext());
cursor.close();
}
} catch (Exception e) {
e.printStackTrace();
}
return arrayList;
}
Please solve this problem ....
