在我的应用程序中，我需要处理 SSLSocket。我有这个在 Android6.0 及更高版本上运行的代码，当我在 Android 5.+ 上运行相同的代码时，我得到了 HandshakeException

private void openSSLSocket(String mHost, int mPort){
    try {
        SocketFactory sf = SSLSocketFactory.getDefault();
        mSocket = (SSLSocket) sf.createSocket(mHost, mPort);
        mSocket.setEnabledProtocols(new String[]{"TLSv1"});
        mInputStream = mSocket.getInputStream();
        mOutputStream = mSocket.getOutputStream();

        mSocket.setSoTimeout(0);

    }catch (Exception e){
        e.printStackTrace();
    }
}

我在 android 开发者网站上阅读了这篇文章并实现了下面的代码我得到了服务器管理员的 .crt 文件

private void openSSLSocketWithCA(String mHost, int mPort) {
    try{

        // Load CAs from an InputStream
        // (could be from a resource or ByteArrayInputStream or ...)
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        // From https://www.washington.edu/itconnect/security/ca/load-der.crt

        InputStream caInput = am.open("star_******_chained.crt");

        Certificate ca;
        try {
            ca = cf.generateCertificate(caInput);
            System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
        } finally {
            caInput.close();
        }

        // Create a KeyStore containing our trusted CAs
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);

        // Create a TrustManager that trusts the CAs in our KeyStore
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);

        // Create an SSLContext that uses our TrustManager
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, tmf.getTrustManagers(), null);

        SSLSocketFactory sf = context.getSocketFactory();
        mSocket = (SSLSocket) sf.createSocket(mHost, mPort);
        mSocket.setEnabledProtocols(new String[]{"TLSv1"});
        mInputStream = mSocket.getInputStream();
        mOutputStream = mSocket.getOutputStream();

        mSocket.setSoTimeout(0);
    }catch (Exception e){
        e.printStackTrace();
    }
}

即使这样，我在调用 mSocket.getInputStream(); 时也会收到 HandshakeException；方法

这是日志

在网上搜索了很多之后。我已登陆此页面更新安全提供程序 最后，此解决方案对我有用

我在我的主要活动的 onCreate 中调用了这段代码

 try {
        ProviderInstaller.installIfNeeded(this);
    } catch (GooglePlayServicesRepairableException e) {
        GooglePlayServicesUtil.getErrorDialog(e.getConnectionStatusCode(), callingActivity, 0);
    } catch (GooglePlayServicesNotAvailableException e) {
        Log.e("SecurityException", "Google Play Services not available.");
    }

这解决了我的问题
