How to list all folders on android?

Question

I want to make an app that scans my phone's memory. I know about Environment.getExternalStorageDirectory(). But there are also other folders on my phone, such as folders used by other applications. When I try to use the linux "du /" command, I get a permission denied error. It will work with root, but there are applications on GooglePlay like Total Commander or Termux that have the ability to scan almost all folders on the device whithout root. So how they do this? 😅

Answer 1

尝试使用Environment.getDataDirectory() 。
