Root explorer Android 11 (API 30)

Question

When I target api 30 and try to retrieve the list of files in the path "/data/data" (with root permissions), I only get the folder of my app, while with api 29 or lower I get all the files present.

How can I retrieve all files even with api 30?

Code used:

import androidx.appcompat.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import com.topjohnwu.superuser.Shell

class MainActivity : AppCompatActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val result = Shell.su("ls -la /data/data").exec()
        Log.e("files", result.out.toString())
    }
}

I used this library for root: https://github.com/topjohnwu/libsu

These are the new limitations added in Android 11: https://developer.android.com/about/versions/11/privacy/storage

Document access restrictions

To give developers time for testing, the following changes related > to the Storage Access Framework (SAF) take effect only if your app targets Android 11 or higher.

Access to directories

You can no longer use the ACTION_OPEN_DOCUMENT_TREE intent action to request access to the following directories:

• The root directory of the internal storage volume.
• The root directory of each SD card volume that the device manufacturer considers to be reliable, regardless of whether the card is emulated or removable. A reliable volume is one that an app can successfully access most of the time.
• The Download directory.

Access to files

You can no longer use the ACTION_OPEN_DOCUMENT_TREE or the ACTION_OPEN_DOCUMENT intent action to request that the user select individual files from the following directories:

• The Android/data/ directory and all subdirectories.
• The Android/obb/ directory and all subdirectories.
