I want to get content (images & videos) of user selected folder. Code to select the folder is:
val intent = Intent(Intent.ACTION_OPEN_DOCUMENT_TREE)
intent.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION
or Intent.FLAG_GRANT_PREFIX_URI_PERMISSION
or Intent.FLAG_GRANT_READ_URI_PERMISSION
or Intent.FLAG_GRANT_WRITE_URI_PERMISSION
)
startActivityForResult(intent, 1088)
And onActivityResult, I am persisting the permission(even I tested without restarting the device but it is not working):
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if(resultCode == Activity.RESULT_OK) {
if (requestCode == 1088) {
val selectedDirUri = data!!.data
grantUriPermission(packageName, selectedDirUri, (Intent.FLAG_GRANT_READ_URI_PERMISSION
or Intent.FLAG_GRANT_WRITE_URI_PERMISSION
or Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION))
val takeFlags = (data.flags
and (Intent.FLAG_GRANT_READ_URI_PERMISSION
or Intent.FLAG_GRANT_WRITE_URI_PERMISSION))
contentResolver.takePersistableUriPermission(selectedDirUri!!, takeFlags)
}
}
}
And I am traversing through all files using:
val rootUri: Uri = Uri.parse(selectedDir)
val contentResolver: ContentResolver = context.contentResolver
var childrenUri = DocumentsContract.buildChildDocumentsUriUsingTree(rootUri, DocumentsContract.getTreeDocumentId(rootUri))
val dirNodes: MutableList<Uri> = LinkedList()
dirNodes.add(childrenUri)
while (!dirNodes.isEmpty()) {
childrenUri = dirNodes.removeAt(0) // get the item from top
val c = contentResolver.query(childrenUri,
arrayOf(
DocumentsContract.Document.COLUMN_DOCUMENT_ID,
DocumentsContract.Document.COLUMN_DISPLAY_NAME,
DocumentsContract.Document.COLUMN_MIME_TYPE,
DocumentsContract.Document.COLUMN_LAST_MODIFIED),
null, null, null)
try {
while (c!!.moveToNext()) {
val docId = c.getString(0)
val fileName = c.getString(1)
val mimeType = c.getString(2)
val lastModified = c.getLong(3)
if (isDirectory(mimeType)) {
val newNode = DocumentsContract.buildChildDocumentsUriUsingTree(rootUri, docId)
dirNodes.add(newNode)
} else {
val newNode = DocumentsContract.buildDocumentUriUsingTree(rootUri, docId)
Logger.log("TAG", "========1 Images: $newNode")
val ***sourceFileUri*** = newNode.toString()
}
}
} finally {
closeQuietly(c)
}
}
Then I display images and videos using Glide, it is not displaying. Even if I try to copy the image using below code:
val inputStream: InputStream? = context.contentResolver.openInputStream(***sourceFileUri***)
I am getting below error, the above line gives an error:
java.lang.SecurityException: com.android.externalstorage has no access to content://media/external _primary/file/1000008384 at android.os.Parcel.createException or Null(Parcel.java:2438) at 08 android.os.Parcel.createException(P arcel.java:2422) at android.os.Parcel.readException(Par cel.java:2405) at android.database.DatabaseUtils.rea dExceptionFromParcel(DatabaseUtil s.java:190) at android.database.DatabaseUtils.rea dException WithFileNotFoundExcepti on From Parcel(DatabaseUtils.java:15 3)
This is happening in Vivo, Oppo and specially in new Samsung phones only which has android OS 11 and 12. I am really frustrated, I tried all possible solution but not able to find any solution till now.
Any solution or advice would be really helpful and appreciated, please please help me.
