我想要使​​用HttpsURLConnection以下密码套件支持连接的服务器.问题是android 5.0不支持以下任何一个密码套件......

SSL_CK_RC4_128_EXPORT40_WITH_MD5
SSL_CK_RC2_128_CBC_EXPORT40_WITH_MD5
TLS_RSA_EXPORT_WITH_RC4_40_MD5
TLS_RSA_EXPORT_WITH_RC2_CBC_40_MD5
SSL_CK_DES_64_CBC_WITH_MD5
SSL_CK_RC4_128_WITH_MD5
SSL_CK_RC2_128_CBC_WITH_MD5
SSL_CK_IDEA_128_CBC_WITH_MD5
TLS_RSA_WITH_RC4_128_MD5
SSL_CK_DES_192_EDE3_CBC_WITH_MD5

那么从客户端那里我无能为力吗？

您应该尝试指定以下密码套件：

CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_CBC_SHA,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_256_CBC_SHA,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA,
                    CipherSuite.TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA,
                    CipherSuite.TLS_DHE_RSA_WITH_AES_128_CBC_SHA,
                    CipherSuite.TLS_DHE_RSA_WITH_AES_256_CBC_SHA,
                    CipherSuite.TLS_DHE_DSS_WITH_AES_128_CBC_SHA,
                    CipherSuite.TLS_DHE_DSS_WITH_AES_256_CBC_SHA,
                    CipherSuite.TLS_ECDHE_ECDSA_WITH_RC4_128_SHA,
                    CipherSuite.TLS_ECDHE_RSA_WITH_RC4_128_SHA,
                    CipherSuite.TLS_RSA_WITH_AES_128_GCM_SHA256,
                    CipherSuite.TLS_RSA_WITH_AES_256_GCM_SHA384,
                    CipherSuite.TLS_RSA_WITH_AES_128_CBC_SHA,
