A description of an Intent and target action to perform with it. Instances of this class are created with getActivity, getActivities, getBroadcast, and 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. 
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.
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 cancel to remove it. 
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 not happen. The parts of the Intent that are used for matching are the same ones defined by Intent.filterEquals. If you use two Intent objects that are equivalent as per Intent.filterEquals, then you will get the same PendingIntent for both of them. 
There are two typical ways to deal with this.
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 Intent.filterEquals, or different request code integers supplied to getActivity, getActivities, getBroadcast, or getService. 
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 FLAG_CANCEL_CURRENT or FLAG_UPDATE_CURRENT to either cancel or modify whatever current PendingIntent is associated with the Intent you are supplying. /**

Like getActivity(Context, int, Intent, int), but allows an array of Intents to be supplied. The last Intent in the array is taken as the primary key for the PendingIntent, like the single Intent given to getActivity(Context, int, Intent, int). Upon sending the resulting PendingIntent, all of the Intents are started in the same way as they would be by passing them to Context.startActivities(Intent[]). 

The first intent in the array will be started outside of the context of an existing activity, so you must use the 
Intent.FLAG_ACTIVITY_NEW_TASK launch flag in the Intent. (Activities after the first in the array are started in the context of the previous activity in the array, so FLAG_ACTIVITY_NEW_TASK is not needed nor desired for them.) 

The last intent in the array represents the key for the PendingIntent. In other words, it is the significant element for matching (as done with the single intent given to getActivity(Context, int, Intent, int), its content will be the subject of replacement by send(Context, int, Intent) and FLAG_UPDATE_CURRENT, etc. This is because it is the most specific of the supplied intents, and the UI the user actually sees when the intents are started. 
For security reasons, the Intent objects you supply here should almost always be explicit intents, that is specify an explicit component to be delivered to through Intent.setClass
Params:
context – The Context in which this PendingIntent should start
the activity.
requestCode – Private request code for the sender
intents – Array of Intents of the activities to be launched.
flags – May be FLAG_ONE_SHOT, FLAG_NO_CREATE, FLAG_CANCEL_CURRENT, FLAG_UPDATE_CURRENT, or any of the flags as supported by Intent.fillIn() to control which unspecified parts of the intent that can be supplied when the actual send happens.
