Case Study: Beer Explorer

Integrating ActionBarSherlock

1. Include source as library project in Eclipse2. Include Android Support Library in build path3. Set theme in manifest:<application android:theme="@style/Theme.Sherlock">

4. Set drop-down view resource if using list navigation:

ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(this, R.array.action_list, R.layout.sherlock_spinner_item);

adapter.setDropDownViewResource(R.layout.sherlock_spinner_dropdown_item);

Using ActionBarSherlock

● getActionBar() => getSupportActionBar()● getActivity() => getSupportActivity()● getFragmentManager() =>

getSupportFragmentManager()● FragmentActivity =>

SherlockFragmentActivity, etc. for various activity types

● Method overrides use ActionBarSherlock types

Ignition Library

● UI components● HTTP wrapper library● HTTP caching framework● Remote image loader● Helper classes for easier API backwards

compatibility, intents, diagnostics, and more● Friendlier and more robust implementation of

AsyncTask

Using the Ignition Library for Beer Explorer

● IgnitedHttp for API requests and caching

● IgnitedAsyncTask for making API requests asynchronously

● RemoteImageView for loading images from URL

Launchpad Library

HttpTask & ApiRequest classes● Combines IgnitedHttp and IgnitedAsyncTask● Wraps caching and GSON
