No Activity found to handle Intent when trying to programmatically ask for permissions

Question

I need to get the MANAGE_ALL_FILES_ACCESS_PERMISSION to be able to download and install APK's from my application.
When I was targeting SDK 27 and lower, everything worked fine, when I declared

in the manifest and asked for permission with ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 100);

But now I need to target SDK 30, meaning that WRITE_EXTERNAL_STORAGE is deprecated and not working for API versions 29 and 30.

I have been trying to find a workaround and one that I could think of was starting the Intent to allow users to switch the permission on by themselves but I cannot get it to work.

The code I am using:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    try {
        Uri uri = Uri.parse("package:" + BuildConfig.APPLICATION_ID);
        Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION, uri);
        startActivity(intent);
    } catch (Exception ex){
        Intent intent = new Intent();
        intent.setAction(Settings.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION);
        startActivity(intent);
    }
} else {
    ActivityCompat.requestPermissions(this,
            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
            100);
}

And the error that I get when trying to open intent:

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.settings.MANAGE_ALL_FILES_ACCESS_PERMISSION }

The error comes from the catch block but the Exception ex gives the same error.

What am I doing wrong or is this just not allowed on the current phone I am using (XCover 4s Android 10).

The answer to getting the storage permission that worked for me.

I had to change the Manifest.permission. strings so instead of what was written in the question I used.

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    ActivityCompat.requestPermissions(
            activity,
            new String[]{
                    Manifest.permission.READ_EXTERNAL_STORAGE,
                    Manifest.permission.MANAGE_EXTERNAL_STORAGE
            },
            1
    );
} else {
    ActivityCompat.requestPermissions(activity,
            new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},
            100);
}

Or similarly this could be used :

if (ContextCompat.checkSelfPermission(activity, Manifest.permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE,Manifest.permission.READ_EXTERNAL_STORAGE}, 1);
}

if (ContextCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE}, 1);
}

Then to get the prompt to allow user to install Apps from unkown sources :

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    if (!activity.getPackageManager().canRequestPackageInstalls()) {
        activity.startActivityForResult(new Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES).setData(Uri.parse(String.format("package:%s", activity.getPackageName()))), 1234);
    } else {
    }
}
