Shadowsocks Setup and Optimization

Tue, 31 Dec 2019 20:29:27 +0000

Network instability at the office was affecting work, so I set up a Shadowsocks server on my VPS for source code pulls. The steps below work on most Linux distributions and have been tested on Ubuntu 16.04 and 18.04.

2024 Update: The Python version of shadowsocks used in this guide is no longer maintained. The actively maintained implementation is shadowsocks-rust, which offers better performance and support for modern encryption protocols. For a fresh setup, refer to the shadowsocks-rust documentation. The original Python-based steps are preserved below for reference.

Android & Linux Tips Collection #3

Three quick tips: handling the back button in DialogFragment, chmod permission reference, and the underscore problem in SSL hostnames.

DialogFragment Back Button Handling

DialogFragment has no direct override for the back button. Two approaches were commonly used.

Approach 1: Override in onCreateDialog

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    return new Dialog(getActivity(), getTheme()){
        @Override
        public void onBackPressed() {
            // Handle back press here
        }
    };
}

Approach 2: Via onKeyListener

@Override
public void onResume() {
    super.onResume();
    Dialog dialog = getDialog();
    if (dialog != null) {
        dialog.setOnKeyListener(this);
    }
}

@Override
public void onPause() {
    super.onPause();
    Dialog dialog = getDialog();
    if (dialog != null) {
        dialog.setOnKeyListener(null);
    }
}

Modern Approach: OnBackPressedDispatcher (AndroidX)
