what to do with this as " HttpClientHelper$1" is referenced by your lib function call and it’s not in your lib. that’s too strange…

PLEASE SUGGEST SOME SOLUTION FOR THIS

1. Could not find class ‘com.mashape.unirest.http.HttpClientHelper$1’, referenced from method com.mashape.unirest.http.HttpClientHelper.prepareCallback

2. Could not find class ‘org.apache.http.nio.entity.NByteArrayEntity’, referenced from method com.mashape.unirest.http.HttpClientHelper.prepareRequest

3. Could not find class ‘org.apache.http.impl.conn.PoolingHttpClientConnectionManager’, referenced from method com.mashape.unirest.http.options.Options.refresh
