******************************************************************************
*
* A cache that uses a bounded amount of space on a filesystem. Each cache
* entry has a string key and a fixed number of values. Values are byte
* sequences, accessible as streams or files. Each value must be between {@code
* 0} and {@code Integer.MAX_VALUE} bytes in length.
*
* <p>The cache stores its data in a directory on the filesystem. This
* directory must be exclusive to the cache; the cache may delete or overwrite
* files from its directory. It is an error for multiple processes to use the
* same cache directory at the same time.
*
* <p>This cache limits the number of bytes that it will store on the
* filesystem. When the number of stored bytes exceeds the limit, the cache will
* remove entries in the background until the limit is satisfied. The limit is
* not strict: the cache may temporarily exceed it while waiting for files to be
* deleted. The limit does not include filesystem overhead or the cache
* journal so space-sensitive applications should set a conservative limit.
*
* <p>Clients call {@link #edit} to create or update the values of an entry. An
* entry may have only one editor at one time; if a value is not available to be
* edited then {@link #edit} will return null.
* <ul>
* <li>When an entry is being <strong>created</strong> it is necessary to
* supply a full set of values; the empty value should be used as a
* placeholder if necessary.
* <li>When an entry is being <strong>edited</strong>, it is not necessary
* to supply data for every value; values default to their previous
* value.
* </ul>
* Every {@link #edit} call must be matched by a call to {@link Editor#commit}
* or {@link Editor#abort}. Committing is atomic: a read observes the full set
* of values as they were before or after the commit, but never a mix of values.
*
* <p>Clients call {@link #get} to read a snapshot of an entry. The read will
* observe the value at the time that {@link #get} was called. Updates and
* removals after the call do not impact ongoing reads.
*
* <p>This class is tolerant of some I/O errors. If files are missing from the
* filesystem, the corresponding entries will be dropped from the cache. If
* an error occurs while writing a cache value, the edit will fail silently.
* Callers should handle other problems by catching {@code IOException} and
* responding appropriately.

direction or management of such entity, whether by contract or
otherwise, or (ii) ownership of fifty percent (50%) or more of the
outstanding shares, or (iii) beneficial ownership of such entity.
"You" (or "Your") shall mean an individual or Legal Entity

not limited to compiled object code, generated documentation,
and conversions to other media types.
"Work" shall mean the work of authorship, whether in Source or
Object form, made available under the License, as indicated by a
copyright notice that is included in or attached to the work
(an example is provided in the Appendix below).
"Derivative Works" shall mean any work, whether in Source or Object
form, that is based on (or derived from) the Work and for which the
editorial revisions, annotations, elaborations, or other modifications
represent, as a whole, an original work of authorship. For the purposes
of this License, Derivative Works shall not include works that remain
separable from, or merely link (or bind by name) to the interfaces of,
the Work and Derivative Works thereof.
"Contribution" shall mean any work of authorship, including
the original version of the Work and any modifications or additions
to that Work or Derivative Works thereof, that is intentionally
submitted to Licensor for inclusion in the Work by the copyright owner
or by an individual or Legal Entity authorized to submit on behalf of
the copyright owner. For the purposes of this definition, "submitted"
means any form of electronic, verbal, or written communication sent
to the Licensor or its representatives, including but not limited to
communication on electronic mailing lists, source code control systems,

"Contributor" shall mean Licensor and any individual or Legal Entity
on behalf of whom a Contribution has been received by Licensor and
subsequently incorporated within the Work.
2. Grant of Copyright License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
copyright license to reproduce, prepare Derivative Works of,
publicly display, publicly perform, sublicense, and distribute the
Work and such Derivative Works in Source or Object form.
3. Grant of Patent License. Subject to the terms and conditions of
this License, each Contributor hereby grants to You a perpetual,
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
(except as stated in this section) patent license to make, have made,
use, offer to sell, sell, import, and otherwise transfer the Work,
where such license applies only to those patent claims licensable
by such Contributor that are necessarily infringed by their
Contribution(s) alone or by combination of their Contribution(s)
with the Work to which such Contribution(s) was submitted. If You
institute patent litigation against any entity (including a
cross-claim or counterclaim in a lawsuit) alleging that the Work
or a Contribution incorporated within the Work constitutes direct
or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the
Work or Derivative Works thereof in any medium, with or without
modifications, and in Source or Object form, provided that You
meet the following conditions:
(a) You must give any other recipients of the Work or
Derivative Works a copy of this License; and
(b) You must cause any modified files to carry prominent notices
stating that You changed the files; and
(c) You must retain, in the Source form of any Derivative Works
that You distribute, all copyright, patent, trademark, and
attribution notices from the Source form of the Work,
excluding those notices that do not pertain to any part of
the Derivative Works; and
(d) If the Work includes a "NOTICE" text file as part of its
distribution, then any Derivative Works that You distribute must
include a readable copy of the attribution notices contained
within such NOTICE file, excluding those notices that do not
pertain to any part of the Derivative Works, in at least one
of the following places: within a NOTICE text file distributed
as part of the Derivative Works; within the Source form or
documentation, if provided along with the Derivative Works; or,
within a display generated by the Derivative Works, if and
wherever such third-party notices normally appear. The contents
of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify
the terms of any separate license agreement you may have executed
with Licensor regarding such Contributions.
6. Trademarks. This License does not grant permission to use the trade
names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the
origin of the Work and reproducing the content of the NOTICE file.
7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the
appropriateness of using or redistributing the Work and assume any
risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf
of any other Contributor, and only if You agree to indemnify,
defend, and hold each Contributor harmless for any liability
incurred by, or claims asserted against, such Contributor by reason
of your accepting any such warranty or additional liability.

/**
* 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
* select items accessible directly from the action bar as "action items". You can also
* modify various characteristics of the action bar or remove it completely.</p>
* <p>From your activity, you can retrieve an instance of {@link ActionBar} by calling {@link
* android.app.Activity#getActionBar getActionBar()}.</p>
* <p>In some cases, the action bar may be overlayed by another bar that enables contextual actions,
* using an {@link android.view.ActionMode}. For example, when the user selects one or more items in
* your activity, you can enable an action mode that offers actions specific to the selected
* items, with a UI that temporarily replaces the action bar. Although the UI may occupy the
* same space, the {@link android.view.ActionMode} APIs are distinct and independent from those for
* {@link ActionBar}.
* <div class="special reference">
* <h3>Developer Guides</h3>
* <p>For information about how to use the action bar, including how to add action items, navigation
* modes and more, read the <a href="{@docRoot}guide/topics/ui/actionbar.html">Action
* Bar</a> developer guide.</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>

* WARNING: This is a workaround for a touch mode issue.

* Touch mode is propagated lazily to windows. This causes problems in
* the following scenario:
* - Type something in the AutoCompleteTextView and get some results
* - Move down with the d-pad to select an item in the list
* - Move up with the d-pad until the selection disappears
* - Type more text in the AutoCompleteTextView *using the soft keyboard*
* and get new results; you are now in touch mode
* - The selection comes back on the first item in the list, even though
* the list is supposed to be in touch mode
*
* Using the soft keyboard triggers the touch mode change but that change
* is propagated to our window only after the first list layout, therefore
* after the list attempts to resurrect the selection.
*
* The trick to work around this issue is to pretend the list is in touch
* mode when we know that the selection should not appear, that is when
* we know the user moved the selection away from the list.
*
* This boolean is set to true whenever we explicitly hide the list's
* selection and reset to false whenever we know the user moved the
* selection back to the list.
*

/**
* <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>
