How do i check for request failure after resuming activity?

[Maxim Komarovsky]

Hi!

First, thanks a lot for your lib, it does make life much easier :)

Second, here is the question: 

1. Somewhere in my Activity i start a (potentially long-running) SpiceRequest by calling

SpiceManager.execute(...);

2. The activity gets stopped and/or destroyed

3. On resume i call

SpiceManager.getFromCache(...);

SpiceManager.addListenerIfPending(...);

Everything works as expected except the case when the request fails before the activity gets resumed or re-created. The only callback I get is OnRequestSuccess(...) with null result after calling getFromCache().

That seems correct as there has been no result to cache and return, but how do I find out that the request has failed?

I could do something like this:

class MyRequest implements SpiceRequest<X extends RequestResultWithError> {

@Override

public X loadDataFromNetwork() throws Exception {

X result;

try{

result = loadData();

} catch(Exception e) {

result.setError(e);

}

return result;

}

}

the request would ALWAYS return a cacheable result, but is there any "built-in" functionality for that case?

Thanks you!

Dobjanschi instructs adding two columns to your database tables, one for status, one for result.  If you insert data into the database before making the network call and set the status to "creating", and your activity checks the database for incomplete requests everytime it starts, then it will see the "creating" status of a failed request and can reinvoke the request.  Obviously the request listener methods need to update these two columns as necessary.

Hi Maxi and Adam,

no such facility is provided in RS. Requests and their status are not persisted, only their results are. I believe that the solutions you propose are valid : creating a custom request that will persist the status of the request separatly.

I wish I also had some time to investigate combining RS and Tape from Square, it could also offer request status persistence.

I have the same problem but I think that your solution is not always OK. 

The processor process request in processRequest will return when it see a NoNetworkException.

The hook method `requestFailure` will be invoked in your listener. You could save that information.
