-/**
- * Base class for code that will receive intents sent by sendBroadcast().
- * You can either dynamically register an instance of this class with
- * {@link Context#registerReceiver Context.registerReceiver()}
- * or statically publish an implementation through the
- * {@link android.R.styleable#AndroidManifestReceiver <receiver>}
- * tag in your <code>AndroidManifest.xml</code>. <em><strong>Note:</strong></em>
- * &nbsp;&nbsp;&nbsp;If registering a receiver in your
- * {@link android.app.Activity#onResume() Activity.onResume()}
- * implementation, you should unregister it in 
- * {@link android.app.Activity#onPause() Activity.onPause()}.
- * (You won't receive intents when paused, 
- * and this will cut down on unnecessary system overhead). Do not unregister in 
- * {@link android.app.Activity#onSaveInstanceState(android.os.Bundle) Activity.onSaveInstanceState()},
- * because this won't be called if the user moves back in the history
- * stack.
- * 
- * <p>There are two major classes of broadcasts that can be received:</p>
- * <ul>
- * <li> <b>Normal broadcasts</b> (sent with {@link Context#sendBroadcast(Intent)
- * Context.sendBroadcast}) are completely asynchronous.  All receivers of the
- * broadcast are run, in an undefined order, often at the same time.  This is
- * more efficient, but means that receivers can not use the result or abort
- * APIs included here.
- * <li> <b>Ordered broadcasts</b> (sent with {@link Context#sendOrderedBroadcast(Intent, String)
- * Context.sendOrderedBroadcast}) are delivered to one receiver at a time.
- * As each receiver executes in turn, it can propagate a result to the next
- * receiver, or it can completely abort the broadcast so that it won't be passed
- * to other receivers.  The order receivers runs in can be controlled with the
- * {@link android.R.styleable#AndroidManifestIntentFilter_priority
- * android:priority} attribute of the matching intent-filter; receivers with
- * the same priority will be run in an arbitrary order.
- * </ul>
- * 
- * <p>Even in the case of normal broadcasts, the system may in some
- * situations revert to delivering the broadcast one receiver at a time.  In
- * particular, for receivers that may require the creation of a process, only
- * one will be run at a time to avoid overloading the system with new processes.
- * In this situation, however, the non-ordered semantics hold: these receivers
- * can not return results or abort their broadcast.</p>
- * 
- * <p>Note that, although the Intent class is used for sending and receiving
- * these broadcasts, the Intent broadcast mechanism here is completely separate
- * from Intents that are used to start Activities with
- * {@link Context#startActivity Context.startActivity()}.
- * There is no way for an BroadcastReceiver
- * to see or capture Intents used with startActivity(); likewise, when
- * you broadcast an Intent, you will never find or start an Activity.
- * These two operations are semantically very different: starting an
- * Activity with an Intent is a foreground operation that modifies what the
- * user is currently interacting with; broadcasting an Intent is a background
- * operation that the user is not normally aware of.
- * 
- * <p>The BroadcastReceiver class (when launched as a component through
- * a manifest's {@link android.R.styleable#AndroidManifestReceiver &lt;receiver&gt;}
- * tag) is an important part of an
- * <a href="{@docRoot}guide/topics/fundamentals.html#lcycles">application's overall lifecycle</a>.</p>
- * 
- * <p>Topics covered here:
- * <ol>
- * <li><a href="#ReceiverLifecycle">Receiver Lifecycle</a>
- * <li><a href="#Permissions">Permissions</a>
- * <li><a href="#ProcessLifecycle">Process Lifecycle</a>
- * </ol>
- * 
- * <a name="ReceiverLifecycle"></a>
- * <h3>Receiver Lifecycle</h3>
- * 
- * <p>A BroadcastReceiver object is only valid for the duration of the call
- * to {@link #onReceive}.  Once your code returns from this function,
- * the system considers the object to be finished and no longer active.
- * 
- * <p>This has important repercussions to what you can do in an
- * {@link #onReceive} implementation: anything that requires asynchronous
- * operation is not available, because you will need to return from the
- * function to handle the asynchronous operation, but at that point the
- * BroadcastReceiver is no longer active and thus the system is free to kill
- * its process before the asynchronous operation completes.
- * 
- * <p>In particular, you may <i>not</i> show a dialog or bind to a service from
- * within an BroadcastReceiver.  For the former, you should instead use the
- * {@link android.app.NotificationManager} API.  For the latter, you can
- * use {@link android.content.Context#startService Context.startService()} to
- * send a command to the service.
- * 
- * <a name="Permissions"></a>
- * <h3>Permissions</h3>
- * 
- * <p>Access permissions can be enforced by either the sender or receiver
- * of an Intent.
- * 
- * <p>To enforce a permission when sending, you supply a non-null
- * <var>permission</var> argument to
- * {@link Context#sendBroadcast(Intent, String)} or
- * {@link Context#sendOrderedBroadcast(Intent, String, BroadcastReceiver, android.os.Handler, int, String, Bundle)}.
- * Only receivers who have been granted this permission
- * (by requesting it with the
- * {@link android.R.styleable#AndroidManifestUsesPermission &lt;uses-permission&gt;}
- * tag in their <code>AndroidManifest.xml</code>) will be able to receive
- * the broadcast.
- * 
- * <p>To enforce a permission when receiving, you supply a non-null
- * <var>permission</var> when registering your receiver -- either when calling
- * {@link Context#registerReceiver(BroadcastReceiver, IntentFilter, String, android.os.Handler)}
- * or in the static
- * {@link android.R.styleable#AndroidManifestReceiver &lt;receiver&gt;}
- * tag in your <code>AndroidManifest.xml</code>.  Only broadcasters who have
- * been granted this permission (by requesting it with the
- * {@link android.R.styleable#AndroidManifestUsesPermission &lt;uses-permission&gt;}
- * tag in their <code>AndroidManifest.xml</code>) will be able to send an
- * Intent to the receiver.
- * 
- * <p>See the <a href="{@docRoot}guide/topics/security/security.html">Security and Permissions</a>
- * document for more information on permissions and security in general.
- * 
- * <a name="ProcessLifecycle"></a>
- * <h3>Process Lifecycle</h3>
- * 
- * <p>A process that is currently executing an BroadcastReceiver (that is,
- * currently running the code in its {@link #onReceive} method) is
- * considered to be a foreground process and will be kept running by the
- * system except under cases of extreme memory pressure.
- * 
- * <p>Once you return from onReceive(), the BroadcastReceiver is no longer
- * active, and its hosting process is only as important as any other application
- * components that are running in it.  This is especially important because if
- * that process was only hosting the BroadcastReceiver (a common case for
- * applications that the user has never or not recently interacted with), then
- * upon returning from onReceive() the system will consider its process
- * to be empty and aggressively kill it so that resources are available for other
- * more important processes.
- * 
- * <p>This means that for longer-running operations you will often use
- * a {@link android.app.Service} in conjunction with an BroadcastReceiver to keep
- * the containing process active for the entire time of your operation.
