volleyにhttpsをサポートさせる

git clone https://android.googlesource.com/platform/frameworks/volley
toolboxにツールクラスを追加する:HTTPSTrustManager.java

public class HTTPSTrustManager implements X509TrustManager {
	
	private static TrustManager[] trustManagers;
	private static final X509Certificate[] _AcceptedIssuers = new X509Certificate[] {};

	@Override
	public void checkClientTrusted(X509Certificate[] x509Certificates, String s)
			throws CertificateException {

	}

	@Override
	public void checkServerTrusted(X509Certificate[] x509Certificates, String s)
			throws CertificateException {
	}
	
	public boolean isClientTrusted(X509Certificate[] chain){
		return true;
	}
	
	public boolean isServerTrusted(X509Certificate[] chain){
		return true;
	}
	
	public static void allowAllowSSL(){
		HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
			
			@Override
			public boolean verify(String hostname, SSLSession session) {
				return true;
			}
		});
		
		SSLContext context = null;
		if(trustManagers == null){
			trustManagers = new TrustManager[]{
					new HTTPSTrustManager()
			};
		}
		
		try{
			context = SSLContext.getInstance("TLS");
			context.init(null, trustManagers, new SecureRandom());
		}catch(NoSuchAlgorithmException e){
			e.printStackTrace();
		}catch(KeyManagementException e){
			e.printStackTrace();
		}
		
		HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory());
	}

	@Override
	public X509Certificate[] getAcceptedIssuers() {
		return _AcceptedIssuers;
	}

}

次にHurlStackを修正する.JAvaでのcreateConnectionメソッド.

    protected HttpURLConnection createConnection(URL url) throws IOException {
    	if("https".equals(url.getProtocol().toLowerCase())){
    		HTTPSTrustManager.allowAllowSSL();
    	}
        return (HttpURLConnection) url.openConnection();
    }

最後にjarパッケージにします.
