i want to detect captive portal network and want to redirect that network to my own webview (which contains custom keyboard).
i tried with below code but its not working . i am testing on KitKat
public class MainActivity extends AppCompatActivity {
private static final String URL = "http://clients3.google.com/generate_204";
private WebView web;
private Network net;
private CaptivePortal captivePortal;
private TextView textView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = getIntent();
if (ConnectivityManager.ACTION_CAPTIVE_PORTAL_SIGN_IN.equals(intent.getAction())) {
net = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK);
captivePortal = intent.getParcelableExtra(ConnectivityManager.EXTRA_CAPTIVE_PORTAL);
}
web = findViewById(R.id.webView);
textView = findViewById(R.id.info_view);
textView.setText(R.string.info_starting);
}
@RequiresApi(api = Build.VERSION_CODES.M)
@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onStart() {
super.onStart();
if (net != null && captivePortal != null) {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
cm.bindProcessToNetwork(net);
final RequestQueue queue = Volley.newRequestQueue(this);
final WebViewClient webClient = new WebViewClient() {
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
textView.setText(R.string.info_portal_injecting);
view.evaluateJavascript("document.getElementById('user.username').value='" + PreferenceManager.getDefaultSharedPreferences(MainActivity.this).getString("pref_user_id", "") + "';" +
"document.getElementById('user.password').value='" + PreferenceManager.getDefaultSharedPreferences(MainActivity.this).getString("pref_password", "") + "';" +
"document.getElementById('aupAccepted').click();" +
"document.getElementById('ui_login_signon_button').click();", new ValueCallback<String>() {
@Override
public void onReceiveValue(String s) {
}
});
captivePortal.reportCaptivePortalDismissed();
finish();
}
};
web.getSettings().setJavaScriptEnabled(true);
web.setWebViewClient(webClient);
NetworkRequest checkConnectionRequest = new NetworkRequest(Request.Method.GET, URL,
new Response.Listener<NetworkResponse>() {
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onResponse(NetworkResponse response) {
if (response.headers.containsKey("Location")) { //some portal returns 200 instead of 302
web.loadUrl(response.headers.get("Location"));
} else {
textView.setText(R.string.info_no_portal);
captivePortal.reportCaptivePortalDismissed();
}
}
},
new Response.ErrorListener() {
@RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onErrorResponse(VolleyError error) {
if (error.networkResponse.statusCode == 302) {
textView.setText(R.string.info_starting);
web.loadUrl(error.networkResponse.headers.get("Location"));
} else {
captivePortal.reportCaptivePortalDismissed();
textView.setText(R.string.info_unknown_error);
}
}
});
queue.add(checkConnectionRequest);
}
}
}
and my another question is how can i test this on Normal networks,is it possible?because right now i dont have any captiveNetworks avaible.is there any trick ? help me with both of these issues.
