Android 11 getting error on uploading pdf selected from internal storage (open failed: EACCES (Permission denied))

Question

When trying to upload selected pdf it will show "open failed: EACCES (Permission denied)" error for that file. It is happening only in Android 11 (API 30). For other version its working fine.

I am using below code to pick pdf from device

`val intent = Intent(Intent.ACTION_OPEN_DOCUMENT).apply {
            type = INTENT_TYPE_PDF
            addCategory(Intent.CATEGORY_OPENABLE)
            putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true)
            }
 startActivityForResult(intent, REQUEST_CODE_PDF_ATTACH)`

On Activity result extracting the file path from Uri

public static String getPath(final Context context, final Uri uri) {
        // 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];
                String storageDefinition;

                if ("primary".equalsIgnoreCase(type)) {
                    return Environment.getExternalStorageDirectory() + "/" + split[1];
                } else {
                    if (Environment.isExternalStorageRemovable()) {
                        storageDefinition = "EXTERNAL_STORAGE";
                    } else {
                        storageDefinition = "SECONDARY_STORAGE";
                    }

After getting the file path upload it to write URL of amazon s3 using

        } else {
            java.io.File file = new java.io.File(localFilePath);
            MediaType contentType = MediaType.parse(contentTypeString);
            requestBody = RequestBody.create(contentType, file);

        }

        DebugLog.d("Upload URL: " + urlToUploadTo);
        Request request = new Request.Builder()
                .url(urlToUploadTo)
                .put(requestBody)
                .build();
