I have problem with BranchSDK, during initialization i receive error:

I tried: https://github.com/BranchMetrics/android-branch-deep-linking/issues/552 and:

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();

P.S. This is problem is on API19, but API 28, 27, 25, 23 all is good worked.

Could you please confirm the SDK version that you are using? As our latest SDK versions had some TLS related changes.

Please refer to: https://github.com/BranchMetrics/android-branch-deep-linking/releases

where release 3.0.0 had some TLS related changes.Please update the Branch SDK and write to integrations@branch.io if the issue still persists.

Thanks.
