解決Volley javax.net.ssl.SSLHandshakeException: java.security.cert.CertP

錯誤詳情：

E/EEE-VOLLEY-error: response error

E/EEE-VOLLEY-error: javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

修改如下：

在繼承的Application類裏面onCreat()方法中調用

handleSSLHandshake()方法忽略https的證書校驗（儘量讓後臺傳正確的證書）

@SuppressLint("TrulyRandom")
public static void handleSSLHandshake() {
    try {
        TrustManager[] trustAllCerts = new TrustManager[]{new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }

            @Override
            public void checkClientTrusted(X509Certificate[] certs, String authType) {
            }

            @Override
            public void checkServerTrusted(X509Certificate[] certs, String authType) {
            }
        }};

        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new SecureRandom());
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
        HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });
    } catch (Exception ignored) {
    }
}
