How to obtain MANAGE_EXTERNAL_STORAGE permission

I'm trying to get the MANAGE_EXTERNAL_STORAGE permission on my Android 10 (API 29) device.

https://developer.android.com/training/data-storage/manage-all-files

Manifest:

<uses-permission android:name="android.permission.MANAGE_EXTERNAL_STORAGE" />

MainActivity:

Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
startActivity(intent);

The result is:

No Activity found to handle Intent { act=android.settings.MANAGE_APP_ALL_FILES_ACCESS_PERMISSION }

Okay, this behaviour is possible. The doc says:

In some cases, a matching Activity may not exist, so ensure you safeguard against this.

But how can I obtain that permission?

// Define the permissions variable correctly
    private val storagePermissions = if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.TIRAMISU) {
        arrayOf(
            Manifest.permission.READ_MEDIA_IMAGES // Android 13+ (API 33) specific permission
        )
    } else {
        arrayOf(
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.WRITE_EXTERNAL_STORAGE
        )
    }
private fun checkAndRequestPermissions() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) { // Android 11+ (API 30)
        // Check if we have "All Files Access" permission (MANAGE_EXTERNAL_STORAGE)
        if (Environment.isExternalStorageManager()) {
            readDataFromCSV()// Permission granted, proceed with saving data
        } else {
            try {
                // Only request permission if supported by the device
                requestAllFilesAccessPermission()
            } catch (e: Exception) {
                Log.e("MainActivity", "Error requesting permission: ${e.message}")
                Toast.makeText(this, "Unable to request permission. Please enable manually in settings.", Toast.LENGTH_LONG).show()
            }
        }
    } else {
        // For Android versions below 11 (API < 30), request legacy permissions
        if (!hasStoragePermissions()) {
            ActivityCompat.requestPermissions(this, storagePermissions, REQUEST_CODE_STORAGE)
        } else {
            readDataFromCSV() // Permission granted, proceed with saving data
        }
    }
}

// Request "All Files Access" permission for Android 11+ (API 30+)
private fun requestAllFilesAccessPermission() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
        if (Environment.isExternalStorageManager()) {
            //todo when permission is granted
        } else {
            //request for the permission
            val intent = Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION)
            val uri = Uri.fromParts("package", packageName, null)
            intent.setData(uri)
            startActivity(intent)
        }
        try {
            startActivityForResult(intent, REQUEST_CODE_STORAGE)
        } catch (e: Exception) {
            Log.e("MainActivity", "Error opening settings: ${e.message}")
            Toast.makeText(this, "Unable to open settings for permission. Please enable it manually in settings.", Toast.LENGTH_LONG).show()
        }
    }
}



// Check if the app has the required storage permissions for Android below API 30
private fun hasStoragePermissions(): Boolean {
    return storagePermissions.all {
        ContextCompat.checkSelfPermission(this, it) == PackageManager.PERMISSION_GRANTED
    }
}

// Handle the results from the permission request
override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)

    if (requestCode == REQUEST_CODE_STORAGE) {
        if (grantResults.all { it == PackageManager.PERMISSION_GRANTED }) {
            readDataFromCSV()  // Permission granted, proceed to save data
        } else {
            Toast.makeText(this, "Permission denied! Cannot save data.", Toast.LENGTH_SHORT).show()
        }
    }
}

it's working for me

Android 10 doesn't require "android.permission.MANAGE_EXTERNAL_STORAGE", android:requestLegacyExternalStorage="true" under application tag in manifest will work.

For android 11, try this

if (Environment.isExternalStorageManager()) {
    //todo when permission is granted
} else {
    //request for the permission
    Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION);
    Uri uri = Uri.fromParts("package", getPackageName(), null);
    intent.setData(uri);
    startActivity(intent);
}
