Question

几个月前我已整合retrofit2;直到昨天与用户（华为，型号MHA-L29，在Android 7.0上）没有问题：

Fatal Exception: java.lang.IllegalArgumentException: Unexpected TLS version: NONE

在我的Gradle：

中

实施'com.squareup.retrofit2：改造：2.3.0'

你有关于此次崩溃的一些想法吗？是否有Retrofit的链接？我没有在OkHttp library中添加Gradle，我必须这样做吗？

Answer 1

你可以通过提供TLS配置来尝试这个吗我不确定这是否有效。从here

引用

ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
        .tlsVersions(TlsVersion.TLS_1_2)
        .cipherSuites(
                CipherSuite.TLS_ECDHE_ECDSA_WITH_AES_128_GCM_SHA256,
                CipherSuite.TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256,
                CipherSuite.TLS_DHE_RSA_WITH_AES_128_GCM_SHA256)
        .build();

OkHttpClient client = new OkHttpClient.Builder()
        .connectionSpecs(Collections.singletonList(spec))
        .build();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(client)
        .build();

Answer 2

我认为此错误是3.11.0版本的结果。您可以在此处查看有关此问题的答案：Android: okhttp3 > crash: Unexpected TLS version: NONE

Android：okhttp3＆gt;崩溃：意外的TLS版本：无
