Javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: protocolo de enlace SSL cancelado: falla en la biblioteca SSL, generalmente un error de protocolo

Encontré la solución analizando los paquetes de datos usando Wireshark. Lo que encontré es que al establecer una conexión segura, Android recurría a SSLv3 desde TLSv1 . Es un error en las versiones de Android <4.4 y se puede resolver eliminando el protocolo SSLv3 de la lista de Protocolos habilitados. Creé una clase socketFactory personalizada llamada NoSSLv3SocketFactory.java. Utilice esto para hacer una fábrica de enchufes.

Utilice esta clase de esta manera mientras se conecta:

SSLContext sslcontext = SSLContext.getInstance("TLSv1");
sslcontext.init(null, null, null);
SSLSocketFactory NoSSLv3Factory = new NoSSLv3SocketFactory(sslcontext.getSocketFactory());

HttpsURLConnection.setDefaultSSLSocketFactory(NoSSLv3Factory);
l_connection = (HttpsURLConnection) l_url.openConnection();
l_connection.connect();

ACTUALIZAR :

Ahora, la solución correcta sería instalar un proveedor de seguridad más nuevo utilizando los servicios de Google Play :

    ProviderInstaller.installIfNeeded(getApplicationContext());

Esto efectivamente le da a su aplicación acceso a una versión más reciente de OpenSSL y Java Security Provider, que incluye soporte para TLSv1.2 en SSLEngine. Una vez instalado el nuevo proveedor, puede crear un SSLEngine que admita SSLv3, TLSv1, TLSv1.1 y TLSv1.2 de la forma habitual:

    SSLContext sslContext = SSLContext.getInstance("TLSv1.2");
    sslContext.init(null, null, null);
    SSLEngine engine = sslContext.createSSLEngine();

O puede restringir los protocolos habilitados usando engine.setEnabledProtocols.

No olvide agregar la siguiente dependencia ( consulte la última versión aquí ):

implementation 'com.google.android.gms:play-services-auth:17.0.0'
