How to get filepath for Documents from Uri in android 10 and android 11 - file-upload

Question

I am creating an app where users will upload pdf or doc files.
I have used default file chooser which returns Uri , now i need to upload those selected files to server
Its working fine upto android 9 ,i am facing issues in android 10 and 11 (i have used android:requestLegacyExternalStorage="true" for android 10 )
val intent = Intent(Intent.ACTION_OPEN_DOCUMENT)
.apply {
addCategory(Intent.CATEGORY_OPENABLE)
type = "*/*"
putExtra(Intent.EXTRA_MIME_TYPES, supportedDocumentTypes.keys.toTypedArray())
}
resultLauncher.launch(intent)
In Activity Result
if (data != null) {
var path = ""
val id = data.data?.lastPathSegment!!
val selection = "_id=?"
if (id.startsWith("msf:") && Build.VERSION.SDK_INT == Build.VERSION_CODES.Q) {
path = FileHelper(requireContext()).getRealPathFromUri(data.data!!.toString()
.replace("msf:","").toUri())!!
}else if (Build.VERSION.SDK_INT == Build.VERSION_CODES.Q){
path = FileHelper(requireContext()).getRealPathFromUri(data.data!!)!!
}else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
path = getDataColumn(context, MediaStore.Downloads.EXTERNAL_CONTENT_URI,
selection, arrayOf(getPath(data.data!!)))
} else {
data.data?.also { uri ->
path = FileHelper(requireContext()).getRealPathFromUri(uri)!!
}
}
Log.e("Doc Path ::",path)
AppUtils.CustomToast(requireActivity(),path)
uploadDocs(path)
}
For getting Document_ID
private fun getPath(uri : Uri) : String {
val contentResolver = requireActivity().applicationContext.contentResolver
val takeFlags: Int = Intent.FLAG_GRANT_READ_URI_PERMISSION or
Intent.FLAG_GRANT_WRITE_URI_PERMISSION
// Check for the freshest data.
contentResolver.takePersistableUriPermission(uri, takeFlags)
val cursor: Cursor? = contentResolver.query(
uri, null, null, null, null, null)
var id = ""
cursor?.use { cursor1 ->
if (cursor1.moveToFirst()) {
val displayName: String = cursor1.getString(cursor1.getColumnIndex(OpenableColumns.DISPLAY_NAME))
Log.i(TAG, "Display Name: $displayName")
val names = cursor1.columnNames.joinToString(",") { it }
Log.e("names ^^^^^",names)
val sizeIndex: Int = cursor1.getColumnIndex(OpenableColumns.SIZE)
val size: String = if (!cursor1.isNull(sizeIndex)) {
cursor1.getString(sizeIndex)
} else { "Unknown" }
Log.i(TAG, "Size: $size")
id = cursor1.getString(cursor1.getColumnIndex(cursor1.columnNames[0]))
Log.e("DocId",id)
}
}
return id
}
Uploading file to server using Retrofit
val builder = MultipartBody.Builder()
builder.setType(MultipartBody.FORM)
val file = File(docPaths)
builder.addFormDataPart("documents", file.name,
RequestBody.create("multipart/form-data".toMediaTypeOrNull(), file))
val requestBody: MultipartBody = builder.build()
I am expecting some code for getting file to upload to server
Thanks In Advance
