I'm constantly getting error:

Basically : org.apache.http.NoHttpResponseException: The target server failed to respond
while the rest interface query doesnt return any error ever.


Is there a specific way i should handle the esri rest api with android api?

Thank you,
Matej

could you give us some details: What are you trying to do?  Maybe a code sample?

In my experience the best way to interact with the rest api is with the esri objects, i.e. ArcGISFeatureLayer, that handles the queries, updates, deletes, credentials, etc.  It also handles all the http connections...
