无法从计算机在 Android 上的外部存储中查看公开创建的文件

Question

I want save a somewhat large json string to a file, then access it from my computer so I can view it and put in a json validator to find out where my problem is. This is for debugging only. I've tried saving to internal and external storage but I cant access my file for the life of me. I can see it from adb shell, but when I try to adb pull it, its not there.

I can also see my file from other apps (like DropBox) on the device, but I cant see it from a computer.

This is the most recent code I tried and should put it in the public downloads folder, but its not there:

File path = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_DOWNLOADS);
path.mkdir();

externalFile = new File(path,JSON_FILE_NAME);

OutputStreamWriter out = new OutputStreamWriter(new FileOutputStream(externalFile));
//write stuff
out.close()

I HAVE added permission to write to external storage.

When you are using MTP to view the files on your PC, they will only show up once the MediaScanner has found them. You can use the following code to force the MediaScanner to scan your file:

MediaScannerConnection.scanFile(getApplicationContext(),
            new String[]{externalFile.toString()}, null, null);
