在我的android应用程序中，我通过https连接。我正在使用自签名证书进行连接。 它正在以下API级别24(机器人牛轧糖之前)，但在Android牛轧糖，它抛出的SSL握手异常设备：SSL握手异常，同时通过https连接使用Android中的自签名证书Nougat

javax.net.ssl.SSLHandshakeException： java.security.cert.CertPathValidatorException：未找到 认证路径的信任锚点。

我这是怎么连接通过https： -

SSLContext context = null;

try

{

KeyStore keyStore = KeyStore.getInstance("PKCS12");

// Get the raw resource, which contains the keystore with

// your trusted certificates (root and any intermediate certs)

InputStream input = new BufferedInputStream(context.getAssets().open(pkcsFilename));

try {

// Initialize the keystore with the provided trusted certificates

// Also provide the password of the keystore

keyStore.load(input, password.toCharArray());

} finally {

input.close();

}

KeyManagerFactory keyFactory = KeyManagerFactory.getInstance(KeyManagerFactory.getDefaultAlgorithm());

keyFactory.init(keyStore, "".toCharArray());

// Load CAs from an InputStream

// (could be from a resource or ByteArrayInputStream or ...)

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

Certificate ca = null;

input = new BufferedInputStream(context.getAssets().open(certificateFilename));

try

{

ca = cf.generateCertificate(input);

}

finally

{

input.close();

}

KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());

trustStore.load(null, null);

trustStore.setCertificateEntry("server", ca);

// Create a TrustManager that trusts the CAs in our KeyStore

TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());

tmf.init(trustStore);

// Create an SSLContext that uses our TrustManager

context = SSLContext.getInstance("TLS");

context.init(keyFactory.getKeyManagers(), tmf.getTrustManagers(), null);

HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();

我尝试以下link，但它并不能帮助。

这是我的网络配置文件。我已将它添加到我的AndroidManifest.xml文件中。

请帮我解决这个问题。
