/**
 * An activity that embeds a {@link WearableListView}. Clients can start this activity by calling
 * {@link WearManager#showWearableList(Activity, WearableListConfig)} like the following example:
 *
 * <pre>
 *     String[] data = new String[] {"List Item 1", "List Item 2", "List Item 3", "List Item 4"};
 *     WearableListConfig config = new WearableListConfig.Builder(data)
 *         .setCheckedIndex(1) // index starts from 0
 *         .setRequestCode(REQUEST_CODE_LIST_DIALOG)
 *         .setIcon(R.drawable.ic_person_24dp)
 *         .setCheckable(true)
 *         .build();
 *     WearManager.getInstance().showWearableList(this, config);
 * </pre>
 *
 * After a selection is made, the caller activity will receiver the response in
 * {@link Activity#onActivityResult(int, int, Intent)}:
 *
 * <pre>
 *     protected void onActivityResult(int requestCode, int resultCode, Intent data) {
 *         if(resultCode == RESULT_OK){
 *             WearableListConfig.WearableListResult result
 *                    = new WearableListConfig.WearableListResult(data,requestCode);
 *             if (result.isHandled()) {
 *                 Log.d(TAG, String.format("Position: %d, Value: %s",
 *                         result.getSelectedIndex(), result.getSelectedValue()));
 *             } else {
 *                 Log.d(TAG, "Another activity is returning a result here ...");
 *             }
