/**
* A window feature at the top of the activity that may display the activity title, navigation
* modes, and other interactive items.
* <p>Beginning with Android 3.0 (API level 11), the action bar appears at the top of an
* activity's window when the activity uses the system's {@link
* android.R.style#Theme_Holo Holo} theme (or one of its descendant themes), which is the default.
* You may otherwise add the action bar by calling {@link
* android.view.Window#requestFeature requestFeature(FEATURE_ACTION_BAR)} or by declaring it in a
* custom theme with the {@link android.R.styleable#Theme_windowActionBar windowActionBar} property.
* <p>By default, the action bar shows the application icon on
* the left, followed by the activity title. If your activity has an options menu, you can make

* calling <code>play(a1).with(a2)</code> sets up the AnimatorSet to play
* <code>a1</code> and <code>a2</code> at the same time,
* <code>play(a1).before(a2)</code> sets up the AnimatorSet to play
* <code>a1</code> first, followed by <code>a2</code>, and
* <code>play(a1).after(a2)</code> sets up the AnimatorSet to play
* <code>a2</code> first, followed by <code>a1</code>.
*
* <p>Note that <code>play()</code> is the only way to tell the
* <code>Builder</code> the animation upon which the dependency is created,
* so successive calls to the various functions in <code>Builder</code>
* will all refer to the initial parameter supplied in <code>play()</code>
* as the dependency of the other animations. For example, calling
* <code>play(a1).before(a2).before(a3)</code> will play both <code>a2</code>
* and <code>a3</code> when a1 ends; it does not set up a dependency between
* <code>a2</code> and <code>a3</code>.</p>

/**
* The <code>Builder</code> object is a utility class to facilitate adding animations to a
* <code>AnimatorSet</code> along with the relationships between the various animations. The
* intention of the <code>Builder</code> methods, along with the {@link
* AnimatorSet#play(Animator) play()} method of <code>AnimatorSet</code> is to make it possible
* to express the dependency relationships of animations in a natural way. Developers can also
* use the {@link AnimatorSet#playTogether(Animator[]) playTogether()} and {@link
* AnimatorSet#playSequentially(Animator[]) playSequentially()} methods if these suit the need,
* but it might be easier in some situations to express the AnimatorSet of animations in pairs.
* <p/>
* <p>The <code>Builder</code> object cannot be constructed directly, but is rather constructed
* internally via a call to {@link AnimatorSet#play(Animator)}.</p>
* <p/>
* <p>For example, this sets up a AnimatorSet to play anim1 and anim2 at the same time, anim3 to
* play when anim2 finishes, and anim4 to play when anim3 finishes:</p>
* <pre>
* AnimatorSet s = new AnimatorSet();
* s.play(anim1).with(anim2);
* s.play(anim2).before(anim3);
* s.play(anim4).after(anim3);
* </pre>
* <p/>
* <p>Note in the example that both {@link Builder#before(Animator)} and {@link
* Builder#after(Animator)} are used. These are just different ways of expressing the same
* relationship and are provided to make it easier to say things in a way that is more natural,
* depending on the situation.</p>
* <p/>
* <p>It is possible to make several calls into the same <code>Builder</code> object to express
* multiple relationships. However, note that it is only the animation passed into the initial
* {@link AnimatorSet#play(Animator)} method that is the dependency in any of the successive
* calls to the <code>Builder</code> object. For example, the following code starts both anim2
* and anim3 when anim1 ends; there is no direct dependency relationship between anim2 and
* anim3:
* <pre>
* AnimatorSet s = new AnimatorSet();
* s.play(anim1).before(anim2).before(anim3);
* </pre>
* If the desired result is to play anim1 then anim2 then anim3, this code expresses the
* relationship correctly:</p>
* <pre>
* AnimatorSet s = new AnimatorSet();
* s.play(anim1).before(anim2);
* s.play(anim2).before(anim3);
* </pre>
* <p/>
* <p>Note that it is possible to express relationships that cannot be resolved and will not
* result in sensible results. For example, <code>play(anim1).after(anim1)</code> makes no
* sense. In general, circular dependencies like this one (or more indirect ones where a depends
* on b, which depends on c, which depends on a) should be avoided. Only create AnimatorSets
* that can boil down to a simple, one-way relationship of animations starting with, before, and
* after other, different, animations.</p>

* menu button itself. This is a soft limit; if an item shares a group ID with an item
* previously included as an action item, the new item will stay with its group and become
* an action item itself even if it breaks the max item count limit. This is done to
* limit the conceptual complexity of the items presented within an action bar. Only a few

* as a single concept.
*
* <p>There is also a hard limit of consumed measurable space: mActionWidthLimit. This
* limit may be broken by a single item that exceeds the remaining space, but no further
* items may be added. If an item that is part of a group cannot fit within the remaining
* measured width, the entire group will be demoted to overflow. This is done to ensure room
* for navigation and other affordances in the action bar as well as reduce general UI clutter.
*
* <p>The space freed by demoting a full group cannot be consumed by future menu items.
* Once items begin to overflow, all future items become overflow items as well. This is

/**
* <p>
* Visual indicator of progress in some operation. Displays a bar to the user
* representing how far the operation has progressed; the application can
* change the amount of progress (modifying the length of the bar) as it moves
* forward. There is also a secondary progress displayable on a progress bar
* which is useful for displaying intermediate progress, such as the buffer
* level during a streaming playback progress bar.
* </p>
*
* <p>
* A progress bar can also be made indeterminate. In indeterminate mode, the
* progress bar shows a cyclic animation without an indication of progress. This mode is used by
* applications when the length of the task is unknown. The indeterminate progress bar can be either
* a spinning wheel or a horizontal bar.
* </p>
*
* <p>The following code example shows how a progress bar can be used from
* a worker thread to update the user interface to notify the user of progress:
* </p>
*
* <pre>
* public class MyActivity extends Activity {
* private static final int PROGRESS = 0x1;
*
* private ProgressBar mProgress;
* private int mProgressStatus = 0;
*
* private Handler mHandler = new Handler();
*
* protected void onCreate(Bundle icicle) {
* super.onCreate(icicle);
*
* setContentView(R.layout.progressbar_activity);
*
* mProgress = (ProgressBar) findViewById(R.id.progress_bar);
*
* // Start lengthy operation in a background thread
* new Thread(new Runnable() {
* public void run() {
* while (mProgressStatus < 100) {
* mProgressStatus = doWork();
*
* // Update the progress bar
* mHandler.post(new Runnable() {
* public void run() {
* mProgress.setProgress(mProgressStatus);
* }
* });
* }
* }
* }).start();
* }
* }</pre>
*
* <p>To add a progress bar to a layout file, you can use the {@code <ProgressBar>} element.
* By default, the progress bar is a spinning wheel (an indeterminate indicator). To change to a
* horizontal progress bar, apply the {@link android.R.style#Widget_ProgressBar_Horizontal
* Widget.ProgressBar.Horizontal} style, like so:</p>
*
* <pre>
* <ProgressBar
* style="@android:style/Widget.ProgressBar.Horizontal"
* ... /></pre>
*
* <p>If you will use the progress bar to show real progress, you must use the horizontal bar. You
* can then increment the progress with {@link #incrementProgressBy incrementProgressBy()} or
* {@link #setProgress setProgress()}. By default, the progress bar is full when it reaches 100. If
* necessary, you can adjust the maximum value (the value for a full bar) using the {@link
* android.R.styleable#ProgressBar_max android:max} attribute. Other attributes available are listed
* below.</p>
*
* <p>Another common style to apply to the progress bar is {@link
* android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}, which shows a smaller
* version of the spinning wheel—useful when waiting for content to load.
* For example, you can insert this kind of progress bar into your default layout for
* a view that will be populated by some content fetched from the Internet—the spinning wheel
* appears immediately and when your application receives the content, it replaces the progress bar
* with the loaded content. For example:</p>
*
* <pre>
* <LinearLayout
* android:orientation="horizontal"
* ... >
* <ProgressBar
* android:layout_width="wrap_content"
* android:layout_height="wrap_content"
* style="@android:style/Widget.ProgressBar.Small"
* android:layout_marginRight="5dp" />
* <TextView
* android:layout_width="wrap_content"
* android:layout_height="wrap_content"
* android:text="@string/loading" />
* </LinearLayout></pre>
*
* <p>Other progress bar styles provided by the system include:</p>
* <ul>
* <li>{@link android.R.style#Widget_ProgressBar_Horizontal Widget.ProgressBar.Horizontal}</li>
* <li>{@link android.R.style#Widget_ProgressBar_Small Widget.ProgressBar.Small}</li>
* <li>{@link android.R.style#Widget_ProgressBar_Large Widget.ProgressBar.Large}</li>
* <li>{@link android.R.style#Widget_ProgressBar_Inverse Widget.ProgressBar.Inverse}</li>
* <li>{@link android.R.style#Widget_ProgressBar_Small_Inverse
* Widget.ProgressBar.Small.Inverse}</li>
* <li>{@link android.R.style#Widget_ProgressBar_Large_Inverse
* Widget.ProgressBar.Large.Inverse}</li>
* </ul>
* <p>The "inverse" styles provide an inverse color scheme for the spinner, which may be necessary
* if your application uses a light colored theme (a white background).</p>
*
