Android Studio中导入NetCipher库求助：实现WebView连接Tor隐藏服务

Hey there! As someone who’s worked with NetCipher for Tor integration in Android apps before, let me walk you through the exact steps to get it set up in your Android Studio project—super straightforward once you know the ropes.

First, open your project in Android Studio and locate the Module-level build.gradle file (it’s the one under your app module, not the root project’s build.gradle). Scroll down to the dependencies block and add these lines:

implementation 'info.guardianproject.netcipher:netcipher:2.2.0'
implementation 'info.guardianproject.netcipher:netcipher-webview:2.2.0'

Note: Double-check the version number—2.2.0 is a stable recent release, but you can use the latest matching versions for both libraries if available.

You’ll need to add permissions for network access and Tor operations. Open your AndroidManifest.xml file and insert these lines right above the <application> tag:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Inside the <application> tag, you can optionally add meta-data to set default Tor settings (this helps streamline setup):

<meta-data
    android:name="info.guardianproject.netcipher.TOR_DEFAULT_ENABLE"
    android:value="true" />
<meta-data
    android:name="info.guardianproject.netcipher.TOR_DEFAULT_SOCKS_PORT"
    android:value="9050" />

You have two easy options here—either use NetCipher’s dedicated WebView or configure your existing WebView to route traffic through Tor.

Option 1: Use NetCipherWebView in Your Layout #

Open your activity’s layout XML file and replace the standard <WebView> with NetCipher’s version:

<info.guardianproject.netcipher.webview.NetCipherWebView
    android:id="@+id/tor_webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

Then in your activity code, load a hidden service URL once Tor connects:

NetCipherWebView torWebView = findViewById(R.id.tor_webview);
// Wait for Tor to connect before loading the URL
OrbotHelper.get(this).startTor(new OrbotHelper.OnTorListener() {
    @Override
    public void onTorConnected() {
        torWebView.loadUrl("http://your-hidden-service.onion");
    }

    @Override
    public void onTorDisconnected() {
        // Handle disconnection if needed
    }

    @Override
    public void onTorConnectionFailed(Exception e) {
        Toast.makeText(getApplicationContext(), "Tor connection failed: " + e.getMessage(), Toast.LENGTH_LONG).show();
    }
});

Option 2: Configure a Standard WebView Programmatically #

If you want to stick with a regular WebView, manually set up the Tor proxy once Tor is connected:

WebView myWebView = findViewById(R.id.my_webview);
WebSettings webSettings = myWebView.getSettings();

OrbotHelper.get(this).startTor(new OrbotHelper.OnTorListener() {
    @Override
    public void onTorConnected() {
        // Set up the SOCKS proxy for Tor
        Proxy torProxy = new Proxy(Proxy.Type.SOCKS, new InetSocketAddress("127.0.0.1", 9050));
        webSettings.setProxyOverride(torProxy);
        // Load your hidden service URL
        myWebView.loadUrl("http://your-hidden-service.onion");
    }

    @Override
    public void onTorDisconnected() {
        // Handle disconnection
    }

    @Override
    public void onTorConnectionFailed(Exception e) {
        Toast.makeText(getApplicationContext(), "Tor connection failed: " + e.getMessage(), Toast.LENGTH_LONG).show();
    }
});

• Make sure your device has active internet access—Tor needs to connect to its network nodes first.
• Tor connections can take a few seconds to establish, so don’t panic if the URL doesn’t load immediately.
• Test with a well-known hidden service (like DuckDuckGo’s onion site) to confirm everything works.

• Orbot Integration: NetCipher relies on Orbot (the official Tor client for Android). If Orbot isn’t installed on the user’s device, NetCipher will automatically prompt them to install it—no extra work needed from you.
• Runtime Permissions: For Android 6.0 (API 23) and above, you’ll need to request ACCESS_NETWORK_STATE permission at runtime if your app targets API 23+.
• Target SDK: Aim for at least API 21 (Lollipop) to ensure full compatibility with NetCipher’s features.
