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 developed an application that uses NFC technology to receive some data when the badge is passed.
When the app is open the screen must always remain accessible and this happens through the use of an external library. It works correctly, but if for example a popup is displayed warning you to update the device, the device goes to lock or if I pass the badge while this window is shown the device instead of using my app to detect the nfc tag uses the system one . How can I solve this problem?
I believe what you're going to need to do for this is use a background isolate.

I am getting installed widgets but I need to find out only running widgets of home screen. Is there any possible solution.
Thanks in advance.
Write your own home screen implementation, where you allow the user to add app widgets to that home screen. Then, you will know what the "running" app widgets are.
Other home screen implementations do not have to publish this information to third parties, and hopefully they do not, for privacy and security reasons.

I'm a beginner in android. I learn the basic concepts one at a time. But now i'm trying to make a slightly large project. How should i approach this? Should I make all the activities first or should i make activities along with code? Or should i just continue on with the anything i like?
The first thing you would need to think of is what exactly your app does.Once you have that in mind the next thing your're going to want to do is think of an interface for the app which usually leads to deciding what information needs to be shown when and on which screen.Once you know what needs to be where you can start the actual coding,i suggest 1 activity at a time.
If you want a large project i suggest a to-do app.

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 had started learning android development and have done most of the ui basics. Now I want to create my own app to know how much I have actually learned. I think all android devs started with one app so which one is the most basic app to create.
Only UI elements,
And no service, broadcast receivers and sq lite stuff. Have not got there yet
You could, for example, google out something like "My first android app"
Something like this is likely to come up:
