1 Coursework 2: getting started (1) – running the phone emulator Chris Greenhalgh G54UBI / Chris Greenhalgh

2 Contents Option 1: using the Android SDK – Installing the Android SDK – Configuring the Android SDK Manager – Creating an emulator – Starting an Emulator Option 2: – Running an Android emulator using the AppInventor local installation 2Chris Greenhalgh

3 Option 1: using the Android SDK (for use with HTML/JS, PhoneGap or native apps) 3Chris Greenhalgh

4 Installing the Android SDK Follow the steps in – Step 1: Ensure you have a JDK (version 1.6) (Eclipse is NOT required at this stage) – Step 2: download the SDK.zip file and extract its contents (e.g. android-sdk-windows/) to your chosen working directory – (Step 3: ADT is NOT required at this stage) 4 Note: this step should NOT be required in the labs: should already be installed in C:\Program Files\Android\android-sdk-windows\ Chris Greenhalgh

5 Setting up the Android SDK (1) (Without Eclipse) run “SDK Manager.exe” from the unpacked directory – (with eclipse, choose Window > Android SDK and AVD Manager) – You can “cancel” the initial dialog which suggests installing all of the available packages – Under “Settings” set the HTTP proxy if required E.g. in the University host “ ” and port “8080” 5 Note: this step should NOT be required in the labs: should already be installed in C:\Program Files\Android\android-sdk-windows\ Chris Greenhalgh

6 Setting up the Android SDK (2) From “Available Packages” select and install at least: – Android SDK Platform-tools and – SDK Platform Android 2.2, API 8 Under Android Repository – Google APIs by Google, Inc., Android API 8 Under Third party add-ons, Google Inc. add-ons [for google maps] – (If you have an older Android device then install a version of Android and Google APIs that is compatible with it) – Note: you will need to click “Accept” for the Google APIs licence: 6 Note: this step should NOT be required in the labs: should already be installed in C:\Program Files\Android\android-sdk-windows\ Chris Greenhalgh

7 Creating an emulator, a.k.a. Android Virtual Device Under Virtual Devices click “New…” and choose – name (any), – target (Google APIs…) – SD Card size, e.g. 64 MB – Resolution (WVGA800) – and Create AVD… Note that the (large) emulator file(s) are usually stored in a hidden directory.android, in your home directory (H:\), which can be deleted if you no longer need the emulator 7 Note: this step should only need to be done ONCE Chris Greenhalgh

8 Starting an emulator Start the SDK Manager if required (see earlier slide) Under “Virtual Devices” select the emulator (“AVD”) you want and click “Start…” – You can modify the launch options if required, e.g. size on the monitor, then press “Launch” – It typically takes a minute or two for the emulator to start up Note: this step needs to be done each time you want to start an emulator 8Chris Greenhalgh

9 A running emulator (exact appearance depends on version and AVD options) 9Chris Greenhalgh

10 Option 2: using the AppInventor tools (for use with Google AppInventor) 10Chris Greenhalgh

11 Installing the AppInventor tools Follow the set-up instructions for your operating system: – html#setupComputer html#setupComputer – Make a note of the installation directory, typically …\AppInventor\commands-for- Appinventor If a web proxy is required then you need to configure it now, e.g. by setting the http_proxy environment variable 11 Note: this should already be installed in the labs in C:\G54UBI\ Chris Greenhalgh

12 Configuring the emulator web proxy From inside the University network (except UoN-guest) if the proxy is not set then you will be able to access University web sites but not external web sites (e.g. google). – At present a suitable proxy from within the University network is “http:// :8080” If you start an emulator from the SDK Manager then it should use the proxy set there (slide 4) Otherwise the emulator will use the environment variable “http_proxy” to determine what (if any) proxy to use – This can be set/checked in (Windows 7) Control Panels  Search “Environment”  Edit environment variables for your account (Windows XP) Control Panels  System  Advanced  Environment Variables – You need to restart the emulator to pick up any change 12Chris Greenhalgh

13 Running the emulator using the AppInventor tools In the AppInventor installation directory ( … \AppInventor\commands-for- Appinventor ) run the emulator command – Windows: double click run-emulator.bat After a few seconds the phone emulator should appear and start up 13 Note: this should be installed in the labs in C:\G54UBI\ Chris Greenhalgh

14 Conclusions You should now be able to: – Install and setup the Android SDK if required – Run an Android emulator – And optionally install the AppInventor tools and run an Android emulator using those 14Chris Greenhalgh
