Android：okhttp3>クラッシュ：予期しないTLSバージョン：なし

Question

2ヶ月前からretrofit2を統合しました。昨日までは何の問題がユーザーにありませんでした（Huawei社、モデルMHA-L29、アンドロイド7.0上）：

私 Gradleで

実装「com.squareup.retrofit2：改造：2.3 .0 '

このクラッシュについてのアイデアはありますか？ Retrofitとリンクしていますか？私はGradleにOkHttp libraryを追加しなかった、私はそれをしなければならない？

Answer 1

TLS設定を提供することでこれを試すことができますか？これがうまくいくかどうかわかりません。 here

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();
