+ * <p>Receivers used with the {@link Context} APIs are by their nature a
+ * cross-application facility, so you must consider how other applications
+ * may be able to abuse your use of them.  Some things to consider are:
+ *
+ * <ul>
+ * <li><p>The Intent namespace is global.  Make sure that Intent action names and
+ * other strings are written in a namespace you own, or else you may inadvertantly
+ * conflict with other applications.
+ * <li><p>When you use {@link Context#registerReceiver(BroadcastReceiver, IntentFilter)},
+ * <em>any</em> application may send broadcasts to that registered receiver.  You can
+ * control who can send broadcasts to it through permissions described below.
+ * <li><p>When you publish a receiver in your application's manifest and specify
+ * intent-filters for it, any other application can send broadcasts to it regardless
+ * of the filters you specify.  To prevent others from sending to it, make it
+ * unavailable to them with <code>android:exported="false"</code>.
+ * <li><p>When you use {@link Context#sendBroadcast(Intent)} or related methods,
+ * normally any other application can receive these broadcasts.  You can control who
+ * can receive such broadcasts through permissions described below.  Alternatively,
+ * starting with {@link android.os.Build.VERSION_CODES#ICE_CREAM_SANDWICH}, you
+ * can also safely restrict the broadcast to a single application with
+ * {@link Intent#setPackage(String) Intent.setPackage}
+ * </ul>
+ *
+ * <p>None of these issues exist when using
+ * {@link android.support.v4.content.LocalBroadcastManager}, since intents
+ * broadcast it never go outside of the current process.
+ *
+ * <p>Access permissions can be enforced by either the sender or receiver
+ * of a broadcast.
+ *
+ * <p>To enforce a permission when sending, you supply a non-null
+ * <var>permission</var> argument to
