android 10 delete folder

Question

If I create a folder in Android 7/9, the location is:

Environment.getExternalStorageDirectory() + "FOLDER_NAME"

But in Android 10 I want to delete the old folder, how I can delete the folder?

I have tried 3 methods so far;

1.

File newFile = new File(Environment.getExternalStorageDirectory() + "FOLDER_NAME");
newFile.delete();

2.

Get the folder list, then delete all files as shown in this thread:

How to delete a whole folder and content?

3.

Using MediaStore way I can not find the folder.

String[] projection = null;

String selection;

String[] selectionArgs;

Cursor cursor = null;

projection = new String[]{ MediaStore.Files.FileColumns._ID, MediaStore.Files.FileColumns.TITLE};

selection = MediaStore.Files.FileColumns.DATA + " like ?";

selectionArgs = new String[]{"%" + "FOLDER_NAME" + "/%"};

Uri external = null;

for (String volumeName : MediaStore.getExternalVolumeNames(context)) {

    external = MediaStore.Files.getContentUri(volumeName);
    break;

}

cursor = context.getContentResolver().query(
MediaStore.Files.getContentUri("external"),
projection,
selection,
selectionArgs,
null);

if(cursor.moveToFirst()) {

Uri fileUri = Uri.withAppendedPath(external,      cursor.getString(cursor.getColumnIndex(MediaStore.Files.FileColumns._ID)));

    ContentResolver resolver = context.getContentResolver();

    resolver.delete(fileUri, null, null);

}

Is there any way I can delete the old folder in Android 10?

Maybe a file manager app for Android Q can do the job.

Otherwise use Storage Access Framework.

Take ACTION_OPEN_DOCUMENT_TREE to let the user choose the parent of your directory.

With obtained write permissions for the parent you can now delete any child.

If you have URI access to that folder, then you can delete it recursively (along with its children) with Simple Storage:

// We want to delete folder /storage/emulated/0/Video/Horror
val folder = DocumentFileCompat.fromSimplePath(context, basePath = "Video/Horror")
// Set childrenOnly to true if you want to delete its children only
val success = folder?.deleteRecursively(context, childrenOnly = false)
