An asynchronous task is defined by 3 generic - * types, called <code>Params</code>, <code>Progress</code> and <code>Result</code>, - * and 4 steps, called <code>onPreExecute</code>, <code>doInBackground</code>, - * <code>onProgressUpdate</code> and <code>onPostExecute</code>.</p> - * - * <div class="special reference"> - * <h3>Developer Guides</h3> - * <p>For more information about using tasks and threads, read the - * <a href="{@docRoot}guide/topics/fundamentals/processes-and-threads.html">Processes and - * Threads</a> developer guide.</p> - * </div> - * - * <h2>Usage</h2> - * <p>AsyncTask must be subclassed to be used. The subclass will override at least - * one method ({@link #doInBackground}), and most often will override a - * second one ({@link #onPostExecute}.)</p> - * - * <p>Here is an example of subclassing:</p> - * <pre class="prettyprint"> - * private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> { - * protected Long doInBackground(URL... urls) { - * int count = urls.length; - * long totalSize = 0; - * for (int i = 0; i < count; i++) { - * totalSize += Downloader.downloadFile(urls[i]); - * publishProgress((int) ((i / (float) count) * 100)); - * // Escape early if cancel() is called - * if (isCancelled()) break; - * } - * return totalSize; - * } - * - * protected void onProgressUpdate(Integer... progress) { - * setProgressPercent(progress[0]); - * } - * - * protected void onPostExecute(Long result) { - * showDialog("Downloaded " + result + " bytes"); - * } - * } - * </pre> - * - * <p>Once created, a task is executed very simply:</p> - * <pre class="prettyprint"> - * new DownloadFilesTask().execute(url1, url2, url3); - * </pre> - * - * <h2>AsyncTask's generic types</h2> - * <p>The three types used by an asynchronous task are the following:</p> - * <ol> - * <li><code>Params</code>, the type of the parameters sent to the task upon - * execution.</li> - * <li><code>Progress</code>, the type of the progress units published during - * the background computation.</li> - * <li><code>Result</code>, the type of the result of the background - * computation.</li> - * </ol> - * <p>Not all types are always used by an asynchronous task. To mark a type as unused, - * simply use the type {@link Void}:</p> - * <pre> - * private class MyTask extends AsyncTask<Void, Void, Void> { ... } - * </pre> - * - * <h2>The 4 steps</h2> - * <p>When an asynchronous task is executed, the task goes through 4 steps:</p> - * <ol> - * <li>{@link #onPreExecute()}, invoked on the UI thread before the task - * is executed. This step is normally used to setup the task, for instance by - * showing a progress bar in the user interface.</li> - * <li>{@link #doInBackground}, invoked on the background thread - * immediately after {@link #onPreExecute()} finishes executing. This step is used - * to perform background computation that can take a long time. The parameters - * of the asynchronous task are passed to this step. The result of the computation must - * be returned by this step and will be passed back to the last step. This step - * can also use {@link #publishProgress} to publish one or more units - * of progress. These values are published on the UI thread, in the - * {@link #onProgressUpdate} step.</li> - * <li>{@link #onProgressUpdate}, invoked on the UI thread after a - * call to {@link #publishProgress}. The timing of the execution is - * undefined. This method is used to display any form of progress in the user - * interface while the background computation is still executing. For instance, - * it can be used to animate a progress bar or show logs in a text field.</li> - * <li>{@link #onPostExecute}, invoked on the UI thread after the background - * computation finishes. The result of the background computation is passed to - * this step as a parameter.</li> - * </ol> - * - * <h2>Cancelling a task</h2> - * <p>A task can be cancelled at any time by invoking {@link #cancel(boolean)}. Invoking - * this method will cause subsequent calls to {@link #isCancelled()} to return true. - * After invoking this method, {@link #onCancelled(Object)}, instead of - * {@link #onPostExecute(Object)} will be invoked after {@link #doInBackground(Object[])} - * returns. To ensure that a task is cancelled as quickly as possible, you should always - * check the return value of {@link #isCancelled()} periodically from - * {@link #doInBackground(Object[])}, if possible (inside a loop for instance.)</p> - * - * <h2>Threading rules</h2> - * <p>There are a few threading rules that must be followed for this class to - * work properly:</p> - * <ul> - * <li>The AsyncTask class must be loaded on the UI thread. This is done - * automatically as of {@link android.os.Build.VERSION_CODES#JELLY_BEAN}.</li> - * <li>The task instance must be created on the UI thread.</li> - * <li>{@link #execute} must be invoked on the UI thread.</li> - * <li>Do not call {@link #onPreExecute()}, {@link #onPostExecute}, - * {@link #doInBackground}, {@link #onProgressUpdate} manually.</li> - * <li>The task can be executed only once (an exception will be thrown if - * a second execution is attempted.)</li> - * </ul> - * - * <h2>Memory observability</h2> - * <p>AsyncTask guarantees that all callback calls are synchronized in such a way that the following - * operations are safe without explicit synchronizations.</p> - * <ul> - * <li>Set member fields in the constructor or {@link #onPreExecute}, and refer to them - * in {@link #doInBackground}. - * <li>Set member fields in {@link #doInBackground}, and refer to them in - * {@link #onProgressUpdate} and {@link #onPostExecute}. - * </ul> - * - * <h2>Order of execution</h2> - * <p>When first introduced, AsyncTasks were executed serially on a single background - * thread. Starting with {@link android.os.Build.VERSION_CODES#DONUT}, this was changed - * to a pool of threads allowing multiple tasks to operate in parallel. Starting with - * {@link android.os.Build.VERSION_CODES#HONEYCOMB}, tasks are executed on a single - * thread to avoid common application errors caused by parallel execution.</p> - * <p>If you truly want parallel execution, you can invoke - * {@link #executeOnExecutor(java.util.concurrent.Executor, Object[])} with - * {@link #THREAD_POOL_EXECUTOR}.</p> - */ -public abstract class AsyncTask<Params, Progress, Result> { - private static final String LOG_TAG = "AsyncTask"; - - private static final int CORE_POOL_SIZE = 5; - private static final int MAXIMUM_POOL_SIZE = 128; - private static final int KEEP_ALIVE = 1; - - private static final ThreadFactory sThreadFactory = new ThreadFactory() { - private final AtomicInteger mCount = new AtomicInteger(1); - - public Thread newThread(Runnable r) { - return new Thread(r, "AsyncTask #" + mCount.getAndIncrement()); - } - }; - - private static final BlockingQueue<Runnable> sPoolWorkQueue = - new LinkedBlockingQueue<Runnable>(10); - - /** - * An {@link Executor} that can be used to execute tasks in parallel. - */ - public static final Executor THREAD_POOL_EXECUTOR - = new ThreadPoolExecutor(CORE_POOL_SIZE, MAXIMUM_POOL_SIZE, KEEP_ALIVE, - TimeUnit.SECONDS, sPoolWorkQueue, sThreadFactory); - - /** - * An {@link Executor} that executes tasks one at a time in serial - * order.

Methods are provided to insert, remove, and - * examine the element. Each of these methods exists in two forms: - * one throws an exception if the operation fails, the other returns a - * special value (either <tt>null</tt> or <tt>false</tt>, depending on - * the operation). The latter form of the insert operation is - * designed specifically for use with capacity-restricted - * <tt>Deque</tt> implementations; in most implementations, insert - * operations cannot fail. - * - * <p>The twelve methods described above are summarized in the - * following table: - * - * <p> - * <table BORDER CELLPADDING=3 CELLSPACING=1> - * <tr> - * <td></td> - * <td ALIGN=CENTER COLSPAN = 2> <b>First Element (Head)</b></td> - * <td ALIGN=CENTER COLSPAN = 2> <b>Last Element (Tail)</b></td> - * </tr> - * <tr> - * <td></td> - * <td ALIGN=CENTER><em>Throws exception</em></td> - * <td ALIGN=CENTER><em>Special value</em></td> - * <td ALIGN=CENTER><em>Throws exception</em></td> - * <td ALIGN=CENTER><em>Special value</em></td> - * </tr> - * <tr> - * <td><b>Insert</b></td> - * <td>{@link #addFirst addFirst(e)}</td> - * <td>{@link #offerFirst offerFirst(e)}</td> - * <td>{@link #addLast addLast(e)}</td> - * <td>{@link #offerLast offerLast(e)}</td> - * </tr> - * <tr> - * <td><b>Remove</b></td> - * <td>{@link #removeFirst removeFirst()}</td> - * <td>{@link #pollFirst pollFirst()}</td> - * <td>{@link #removeLast removeLast()}</td> - * <td>{@link #pollLast pollLast()}</td> - * </tr> - * <tr> - * <td><b>Examine</b></td> - * <td>{@link #getFirst getFirst()}</td> - * <td>{@link #peekFirst peekFirst()}</td> - * <td>{@link #getLast getLast()}</td> - * <td>{@link #peekLast peekLast()}</td> - * </tr> - * </table> - * - * <p>This interface extends the {@link Queue} interface.
