I have specifications from my employer. He wants me to track the use of 3rd party apps from inside of our application. Our application is suppose to act as an operating system. We launch 3rd party apps from our application. Is there any way to track how long a user is using these apps?
The only thing I could think of is starting the timer when I start the intent to launch the app, and upon return to our application stopping the timer. Any ideas on a more concrete idea? Thank you in advance.
Have you looked into Interacting with Other Applications does any of that apply? Your method does seem like the only possible way but I would do it by checking the system time in the onPause and onResume J.I.C your stops whilst being on the other app :) Hope I helped!

If any unknown number call on my phone, the phone should not ring usually it will when contact is saved.
Can the unknown call be picked in background without noticing and a pre-recorded voice should be spoken to person opposite side.
Please mention if can be done on both iOS and android or anyone or none.
Thanks for Help.
Both operating systems will not allow you to do that. 1st point is somehow possible in Android but 2nd one is almost impossible to do in both platforms.
Apple dont allows to intercept most of their system APIs by some 3rd party

The use case:
I want my kids to do some extra home work before they can play their favorite games on the phone. So, when they try to lauch these apps, I want my app to be lauched first. Only after they have finished certain tasks, say a couple of multiple choice questions, can they close my app and continue to their intended apps.
Is this possible to implement in Android? How?
You could do this -- not with an app, but with a custom launcher. You could create a launcher that knows which apps are the "fun" apps and which are the "learning" apps.
Do a search on "android build custom launcher" to get started in the right direction.

I want to build an app which consists of two apks installed separately in device. The first one is main app and other is dependent.
One I thought of is my main app will get the updates from the device, through implementing BroadcastReceivers and then it will send updates to the dependent application through custom BroadcastReceiver.
An example is Go locker app. It have a main app and themes (are installed separately).
I want to know the ways I can go through and also please suggest me the best ways to achieve this.

I am new to android and I would like to write a "Social" android application that would require voice calling between two phones. How should I approach this? Or would it be easier if I "outsource" the voice calling part to another program like Skype?
Thanks!
The quick easy solution is to use the ACTION_CALL intent and use whatever default calling application the user has. If you want to do the whole thing in your app Twilio has a pretty good SDK, but I don't know that I'd recommend getting into that on your first android app..

i am developing an app, in which some data is written in a file during a process in the app.
Now what i need to do is to delete that data from that same file during uninstallation and want that same file to be there in the mobile. Can anybody tell me,, is it possible ?
You have no way of knowing this (in short of exploiting some security hole in Android). Just like #FoamyGuy said, this could make an app do a bunch of bad things. There is an intent called ACTION_PACKAGE_REMOVED which is broadcasted when an application is uninstalled. The catch is it is send to all apps except the one being uninstalled.
This is confirmed here in the docs
Now if you are feeling especially nefarious and if you have two of your apps on the users device, then you can listen to the ACTION_PACKAGE_REMOVED intent for each other. But that isnt very feasible and a story for another day.
