data cache for odata4j

Question

I am implementing a RESTlet service via odata4j on Android.

When running the application there is a constant flow of data, which needs to be sent to a odata server.

The following method get's the new data:

private void freshData(Data data) {
    try {
        dataTransmitter.sendData(data, this.ptId);
    } catch (Exception ex) {
        //
    }

The following method sends the data to the server:

ODataJerseyConsumer c = ODataJerseyConsumer.create(serviceUrl);

public void sendData(Data data, int ptId) throws Exception {
    OEntity newData = c.createEntity(entitySet)
            .properties(OProperties.int32("ptID", ptID), 
             OProperties.double_("data", data.getDouble())))
            .execute;

So far no problem. But what if the mobile connection is cut off or lags?

1) Is there way to get the status from execute() (positive send, or no mobile connection for instance).

2) If the send has failed, or is still in progress I somehow need to store the new data to send it, when the old data is out. Is there a feature in odata4j (0.8-SNAPSHOT) available I haven't found, or do I need to do this with a queue for example?

Thank you for the help!
