how to identify Pending Intent has been launch through NotificationService?

I wrote an long live Service...which actually lauch Notification Panel. I create Pending Intent to launch Activity element of same app.
So here is there any way to identify pending intent launch event?

Put something in the extras of the intent that you're passing to the getActivity method when you're creating your PendingIntent. Then, in the onCreate method of the activity you're opening, check if that field has been set in the extras.

How to differentiate From Which Activity the current intent comes

Form Activity Login I call
Intent intent=new Intent(LogIn.this,BRInfoActivity.class);
From Activity BrActivityList I Call
Intent intent=new Intent(BRActiviList.this, BRInfoActivity.class);
intent.putExtra("BRinfo", objBR);
And Now in BRInfoActivityList
Intent i = getIntent();
BrInfoEN objBR=(BrInfoEN)i.getSerializableExtra("BRinfo");
Now i want if(intent==BrActivityList)The last two above line execute otherwise does not.How to do it?

If you will start activity with
startActivityForResult().
Then you can use getCallingActivity() to get caller.

Form Activity Login call this--
Intent intent=new Intent(LogIn.this,BRInfoActivity.class);
intent.putExtra("call_from","ActivityClass");
From Activity BrActivityList Call--
Intent intent=new Intent(BRActiviList.this, BRInfoActivity.class);
intent.putExtra("call_from", "BRActivity");
Now, when you get the intent, compare the "call_from" string in an if-else block! That's it!

May this help you...
The new intent comes as part of onNewIntent(Intent). The original Intent is still available via getIntent().
You put whatever code you need to into onNewIntent in order to update the UI with the new parameters; probably similar to what you're doing in onCreate.
Also, you probably want to call setIntent(intent) in onNewIntent to make sure future calls to getIntent() within the Activity lifecycle get the most recent Intent data.

Intent extras missing when activity started

Inside a broadcast receiver I want to start my app (Activity) and pass in some data.
My problem is that the extras don't seem to carry over into the activity. I am trying to get the data inside the onNewIntent(Intent i) function.
Any ideas?
Here is my current attempt in the BroadcastReceiver:
Intent intSlider = new Intent();
intSlider.setClass(UAirship.shared().getApplicationContext(), SliderMenuActivity.class);
intSlider.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intSlider.putExtra("action", ScreensEnum.Object);
intSlider.putExtra("objectId", objectId);
intSlider.putExtra("objectCode", objectCode);
intSlider.putExtra("userId", userId);
UAirship.shared().getApplicationContext().startActivity(intSlider);
EDIT - Added code used in onNewIntent() and onCreate()
The following code works great in onCreate() when the app isn't currently running. For when the app is already running the same code doesn't work (i.e. no extras) from the onNewIntent() function.
Intent intent = getIntent();
if(intent.hasExtra("objectId")) {
loadDetail(intent.getStringExtra("objectId"), "2w232");
}

The problem is getIntent() method. It always returns the intent that started the activity, not the most recent one. You should use intent that was passed to onNewIntent method as an argument.

We stumbled upon this problem once, when we were trying to launch/call onNewIntent on an Activity in response to a local notification tap. The extras that we put on our Intent were disappearing at the time onNewIntent received it.
I don't remember this being documented anywhere back then, but the "problem" was that we weren't setting the action field on the Intents that we prepared. Turns out if the Intent received by your Activity doesn't have an action set using setAction, the system still delivers the Intent to its destination, but doesn't transmit the extras you have set while creating the Intent.
TL;DR:
If you encounter this problem with an Intent with no action, calling setAction to set an arbitrary action value before sending the Intent might fix it.

Extract from the docs
This is called for activities that set launchMode to "singleTop" in
their package, or if a client used the FLAG_ACTIVITY_SINGLE_TOP flag
when calling startActivity(Intent). In either case, when the activity
is re-launched while at the top of the activity stack instead of a new
instance of the activity being started, onNewIntent() will be called
on the existing instance with the Intent that was used to re-launch
it.
An activity will always be paused before receiving a new intent, so
you can count on onResume() being called after this method.
Note that getIntent() still returns the original Intent. You can use
setIntent(Intent) to update it to this new Intent.
I think the last paragraph explains your problem.

You have to set the flag FLAG_ACTIVITY_SINGLE_TOP or set launchMode singleTop in the manifest file.
Of course when onNewIntent is called you do not use getIntent but the Intent received as argument.
onNewIntent will be called when the activity instance already exists. For example, if last time you pressed the Home Screen button.
I wrote a solution that worked for me here: Intent with old extra in onCreate() for singleTask Activity

You can store the last received intent in a member variable (mLastIntent).
Then you can use this member in your onResume() method to query for your extra data.
private Intent mLastIntent;
#Override
protected void onNewIntent(Intent intent) {
mLastIntent = intent;
};

Android 2.3.3 | Differentiating Intents That Start an Activity

In Android 2.3.3, how does one differentiate Intents that start a particular Activity. For example, if both Activity_A and Activity_B have intents that call startActivityForResult( intent, requestCode), how does Activity_C differentiate between which Activity has started it? Also, I know that one passes a requestCode to the starting Activity, but how does this Activity handle the requestCode? There is no method in Intent that says getRequestCode(). Is the only way to do this to place the requestCode in a Bundle in addition to the method startActivityForResult? Thanks!

Intent API:
http://developer.android.com/reference/android/content/Intent.html
One solution would be to pass along an extra piece of identifying data. For example:
intent.putExtra("activity", "com.whatever.MyActivity");
Then the receiving Activity can read it:
Bundle extras = getIntent().getExtras();
String activityName = extras.getString("activity");
It seems like there should be an easy method call to tell what the sending Intent was, but if so, I'm not aware of it.

difference between intent and intenfilter in android

Hi friends
can anybody tell what is the use of intent filter and what is difference between intent and intent filter
Thanks

An Intent is an object passed to Context.startActivity(),Context.startService() or Activity.startActivityForResult() etc. to launch an activity or get an existing activity to do something new.
While an Intent filter describes a capability of the component(like activities, services, and broadcast receivers )
For more details see this

Intent's are used to start new activity from the current activity. With two ways
1) Activity.startActivity(intent);
2) Activity.startActivityForResult(intent,rqwuestCode);
//The above thing's you need to put in .java file
Intent-filter you need to mention on manifeast file.
// Intent filter are used for broadcast receiver. Whenever the intent filter condition is match the android OS will launch that activity.

An intent is an object that can hold the os or other app activity and its data in uri form.It is started using startActivity(intent-obj)..\n whereas IntentFilter can fetch activity information on os or other app activities.
