OkHttpClient client = new OkHttpClient.Builder()
            .readTimeout(1000, TimeUnit.MILLISECONDS)
            .writeTimeout(1000, TimeUnit.MILLISECONDS)
            .build();

The OkHttp 3.12.x branch supports Android 2.3+ (API level 9+) and Java 7+. These platforms lack support for TLS 1.2 and should not be used. But because upgrading is difficult, we will backport critical fixes to the 3.12.x branch through December 31, 2021.
