Summary
In this chapter, we covered a lot of ground creating complex layouts using different layout managers such as LinearLayout, TableLayout, and ScrollView and using EditText to validate the form data.
Now a new activity is added to POIApp that displays the details of the POI and allows the user to perform add, update, or delete POI operations. The StartActivity method is used in combination with Intent for passing the data bundle between activities.
We also extended the POIService class by adding additional methods to perform the web service POST and DELETE operations.
The next chapter will guide you to deal with the application behavior when a device orientation changes.
