How to deal with the need for interprocess communication in my Android application?

Question

My application requires me to periodically do the following:

• Send periodic heart rate information to the server every 15 seconds
• Periodically capture the screen and send them to the server once every 60 seconds
• Send a message and poll the server for messages every 5 seconds

I wrote services for each of the above elements, but here I need help, the connection between these services ...

The heartbeat service should be able to:

• Get information from the screen capture service.
• Message queue using the messaging service.

The screen capture service should be able to do the following:

• Get current activity from my application
• Message queue using the messaging service.

The messaging service should be able to do the following:

• Receiving messages in the queue for sending to the server from my application / services
• Send messages received from the server to the application

With all the necessary communication paths, I wonder how to do this? Can I just bind my application to all services? Link services to other services? Use any other way of communication?

I need all these services to continue to work / work, even if my application is not in the foreground.

Provided more chat information , but overall craving:

• use AlarmManager to schedule broadcast receiver calls.
• allows relay receiver on call
• let the recipient send a command to the service (this will start the service if it does not start)
• let the service rotate the flow
• make HTTP in a stream
