Hello everyone :

I created an offline app according to work requirements.It works good when i test with network.But when i cut the network,and open my app,it shows blank.Dose Arcgis supports without networking totally?

Hi,

The offline map should work without network as long as the layers within the map are accessible offline.

What layers does your offline map have. And what does the load status of Map & the layers suggest when you opened them offline.

Thanks
Rama

thanks for answer! I just added basemap in my app.

load status: FAILED_TO_LOAD.

load exception:java.net.UnknownHostException: Unable to resolve host "basemaps-api.arcgis.com": No address associated with hostname.

Looks like you are trying to access a connected layer without network connection.

If you are specifically looking to work with an offline map that has a Basemap that works disconnected, then you can take one of the esri's Basemap offline and use it. The below samples do that by either downloading tile package from service or use an already downloaded tile package.

I Initialized the ArcGISMap by Basemap.Type.DARK_GRAY_CANVAS_VECTOR which needs network.I followed the samples you provided it works ,thanks a lot!
