Zooming views

Zoom controls

• Touching (clicking on) the view or dragging it slightly should show the zoom controls– Alternatively double tap / click

to zoom in and out alternately– On a real device use the “pinch”

zoom gesture:

Check/Exercise

• View the Computer Science home page in the browser (“http://www.cs.nott.ac.uk”)– Unlock the phone, open the browser,

scroll to see the URL box, tap it and enter the URL, press Go and check that the School homepage appears

• Try the same for an external site, e.g. “http://www.google.com”– If you can’t access this from an

emulator in the University refer to notes starting an emulator, in particular proxy settings

Using a real device (only!): Wireless

• Setting up WiFi access in the University: see– http://www.nottingham.ac.uk/is/connect/wireless

/index.aspx– Note that UoN-secure will NOT allow access to

external web sites (e.g. google maps) from Android because a proxy cannot be set on a real device

Note: you cannot set up wireless access on an Emulator; it uses the host machine’s network

Chris Greenhalgh (cmg@cs.nott.ac.uk) 12

Using a real device: Location

• Check that GPS is enabled– Disabling use of wireless may give more consistent

results in some situations

Note: this should already be configured correctly in an Emulator

Chris Greenhalgh (cmg@cs.nott.ac.uk) 13

Using a real device: development• To install applications: – allow “Unknown sources”

• To allow debug/logging over USB: – allow “USB debugging”

• To allow “faking” of GPS position (inc. emulator):– Allow “Allow mock locations”

Note: this should already be configured correctly in an Emulator

Conclusions

• You should now be able to– Use an Android device, in particular– Navigate the home screen– Use the built-in browser– Check standard settings
