Is it possible to get latest missed call or received sms notification from a class which we created on android?

I am able to see getting new sms or calllog from apks which I built but my question is that;
for example I create a .class which in
<com.example.xx
Can I use it on my any other apk's layout xml file using <com.example.xx ... /> using with layout width and height.
Is that possible? If so can you create this class file ?
( I know manifest needs receiver and permissions for latest missed calls & messages)
I hope I can explain clearly what I mean
I'm also not sure what you're asking, but...
Yes, you can access the latest sms or the call log from any Activity you want, from any apk you want, and/or from pretty much from anywhere you want on the phone.
You'd use a Content Provider to access that information. If you wanted to, you could even use a Broadcast Receiver to trigger your application whenever you received a message or phone call.
And yes, you could even do this in a library if you wanted (so that others could use it from their own layouts). If that's what you're asking.
And yes, you could even do this from one apk to another apk through intents if you wanted (not that I would see any advantage to doing that). May be, that last one is not what you were asking.
Have I answered your question?

Get application uninstall event in android
According to this post what you ask for is not possible. Are you by any chance using a C2DM implementation?
Unfortunately there is currently no way for an Android package to execute code when it is removed. However, you can register a BroadcastReceiver for ACTION_PACKAGE_REMOVED in a different package that will be called when packages are removed from the phone.

See this.
If you can't do that (as in, get that permission), then you can't accomplish this.

Show Toast on Missed Call in android application

i want to show a Toast in an Activity when a missed call happened. How can i do it?
Thanks in advance.
I suppose you have content providers to access call logs.

If this code works you just need to run this query at the right time. I mean check some samples that can notify you when you get a call in your device
http://groups.google.com/group/android-developers/browse_thread/thread/d97a759a3708cbe3
Once you get this notification put a timer or use some built in Intents to find that the phone is back to normal state and access the call logs...
There was a similar question recently, the answer should work for you as well:
broadcast receiver for missed call in android
showing the toast afterwards should be the easy part :)
