Android：okhttp3>崩溃：意外的TLS版本：NONE

Question

I've integrated retrofit2 since couple of months ago; there were no problem until yesterday with an user (Huawei, model MHA-L29, on Android 7.0):

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

In my Gradle :

implementation 'com.squareup.retrofit2:retrofit:2.3.0'

Have you got some ideas about this crash? Is there a link with Retrofit ? I didn't add OkHttp library in my Gradle , I must do it?

Answer 1

Can you try this by providing TLS configuration I am not sure if this will work. referred from 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();
