Do you have used Okhttp library ? It is very good library for network calls. You can handle this exception it that also.

I had similar issue and i have managed it with this :

public static OkHttpClient getHttpClientForFile() {
        ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                .tlsVersions(TlsVersion.TLS_1_0)
                .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,
                        CipherSuite.TLS_DHE_RSA_WITH_AES_128_CBC_SHA,
                        CipherSuite.TLS_RSA_WITH_AES_128_CBC_SHA,
                        CipherSuite.TLS_RSA_WITH_3DES_EDE_CBC_SHA)
                .build();
        return new OkHttpClient.Builder()
                .connectTimeout(2, TimeUnit.MINUTES)
                .writeTimeout(2, TimeUnit.MINUTES)
                .readTimeout(3, TimeUnit.MINUTES)
                .connectionSpecs(Collections.singletonList(spec))
                .protocols(Arrays.asList(Protocol.HTTP_1_1))
                .build();
    }

I don't know whether it is good or not, but it is working for me.

The class you have used SSLSocketFactory may produce error after publishing app on play store or play store may give you warning to change your code.

You can find Okhttp library from https://github.com/square/okhttp.
