Drawing pad future plan
We learnt how to save data both locally and remotely.
In mobile app, we should not think the internet is always available. In PhoneGap, we can use the connection to know which type of connection the device currently uses.
We can treat the connection as reliable when the value is
Connection.WIFI. While it is
Connection.CELL_4G, we can assume the user is on the go and network may become unrelaible sometimes. When the type is
Connection.NONE, the device losts connection.
In our drawing pad example, we can store the drawings locally with WebSQL and send to the web service when the network is fast enough.
What’s next? We’re going to take a look at “Project 11 – Accessing Device Resources”.
