| /** |
| * A description of an Intent and target action to perform with it. Instances |
| * of this class are created with {@link #getActivity}, {@link #getActivities}, |
| * {@link #getBroadcast}, and {@link #getService}; the returned object can be |
| * handed to other applications so that they can perform the action you |
| * described on your behalf at a later time. |
| * |
| * <p>By giving a PendingIntent to another application, |
| * you are granting it the right to perform the operation you have specified |
| * as if the other application was yourself (with the same permissions and |
| * identity). As such, you should be careful about how you build the PendingIntent: |
| * almost always, for example, the base Intent you supply should have the component |
| * name explicitly set to one of your own components, to ensure it is ultimately |
| * sent there and nowhere else. |
| * |
| * <p>A PendingIntent itself is simply a reference to a token maintained by |
| * the system describing the original data used to retrieve it. This means |
| * that, even if its owning application's process is killed, the |
| * PendingIntent itself will remain usable from other processes that |
| * have been given it. If the creating application later re-retrieves the |
| * same kind of PendingIntent (same operation, same Intent action, data, |
| * categories, and components, and same flags), it will receive a PendingIntent |
| * representing the same token if that is still valid, and can thus call |
| * {@link #cancel} to remove it. |
| * |
| * <p>Because of this behavior, it is important to know when two Intents |
| * are considered to be the same for purposes of retrieving a PendingIntent. |
| * A common mistake people make is to create multiple PendingIntent objects |
| * with Intents that only vary in their "extra" contents, expecting to get |
| * a different PendingIntent each time. This does <em>not</em> happen. The |
| * parts of the Intent that are used for matching are the same ones defined |
| * by {@link Intent#filterEquals(Intent) Intent.filterEquals}. If you use two |
| * Intent objects that are equivalent as per |
| * {@link Intent#filterEquals(Intent) Intent.filterEquals}, then you will get |
| * the same PendingIntent for both of them. |
| * |
| * <p>There are two typical ways to deal with this. |
| * |
| * <p>If you truly need multiple distinct PendingIntent objects active at |
| * the same time (such as to use as two notifications that are both shown |
| * at the same time), then you will need to ensure there is something that |
| * is different about them to associate them with different PendingIntents. |
| * This may be any of the Intent attributes considered by |
| * {@link Intent#filterEquals(Intent) Intent.filterEquals}, or different |
| * request code integers supplied to {@link #getActivity}, {@link #getActivities}, |
| * {@link #getBroadcast}, or {@link #getService}. |
| * |
| * <p>If you only need one PendingIntent active at a time for any of the |
| * Intents you will use, then you can alternatively use the flags |
| * {@link #FLAG_CANCEL_CURRENT} or {@link #FLAG_UPDATE_CURRENT} to either |
| * cancel or modify whatever current PendingIntent is associated with the |
| * Intent you are supplying. |
