Just a quick question, how to I get a list of directories inside a specified directory.
for example,
String path = Environment.getExternalStorageDirectory().toString()+"/myApp/";
now I'd need to get the list of directories that are inside the "path" directory.
Thanks!
This example will dir list folder and add to list then display as toast. You need to add permission Read External File, if not, your app will crash when trying to dir "/sdcard".
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

<application
