使用digicert更新服务器中的证书后，Android ssl证书错误

我一直在原始文件夹下的android应用程序中使用服务器团队提供的ssl证书密钥.最初运行良好.

I have been using the ssl certificate key provided by the server team in android application under raw folder.It was working fine initially.

     CertificateFactory cf = CertificateFactory.getInstance("X.509");

        InputStream caInputMmx = new BufferedInputStream(this.getAssets().open("123.crt"));
        Certificate caMmx = cf.generateCertificate(caInputMmx);
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("caMmx", caMmx);
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, tmf.getTrustManagers(), null);
        client.setSslSocketFactory(context.getSocketFactory());

几天后，证书过期，服务器团队更新了该证书.从那时起，我们的android应用程序停止工作并出现以下异常

After some days ,the certificate got expired and the server team renewed the certificate.From that point of time our android application stopped working with below exception

com.android.volley.NoConnectionError:javax.net.ssl.SSLHandshakeException:java.security.cert.CertPathValidatorException:找不到证书路径的信任锚.

在使用服务器上的新续订证书时，我们的应用程序可以正常工作.是否有任何解决方法可从服务器上修复此问题，而不是每次都在应用程序中更新新证书?因为如果用户不更新应用程序，我们的应用程序将无法正常工作.因此，有什么方法可以解决此问题，而不是每次证书过期时都在应用程序中更新证书.

On using the new renewed certificate from server our application works fine .Is there any workaround to fix this from server rather updating the new certificate in application every time ? Because if the user does not update the application , our app is not going to work. So is there any way to solve this issue instead of updating the cert in application every time if the certificate is expired .
