How to enable SSL debugging on the Android platform?

Question

Is there something similar to setting -D javax.net.debug=ssl at the command line for Java desktop applications, but for the Android? I\'ve tried setting it in code

Answer 1

you can write a TrustManager class to handle it. example :

ClientConnectionManager cm = new BasicClientConnectionManager();
cm.getSchemeRegistry().register(createHttpsScheme());
DefaultHttpClient client = new DefaultHttpClient(cm);
String url = "https://your domain/your url";
HttpGet get = new HttpGet(url);
HttpResponse resp = client.execute(get);

etc..

public static Scheme createHttpsScheme() {
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, new TrustManager[] {
                new TestTrustManager()
        }, new SecureRandom());

        SSLSocketFactory sf = new SSLSocketFactory(context);
        return new Scheme("https", 443, sf);
}

int TestTrustManager.java you can print the chain like this:

public class TestTrustManager implements X509TrustManager {
    @Override
    public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

       for (int i = 0; i < chain.length; ++i) {
        System.out.println(chain[i]);
       }

       decorated.checkServerTrusted(chain, authType);
  }
}
