Firstly, again, thank you for your answering. But, it is hard to say your answer has answered my question, right? And I thought, you said that my topic was too large to suit for quick question, so I moved it here, I don't think I has offended anybody. But anyway, I am new here, I haven't learn the rules yet, so maybe I did it wrongly.
Your question is far too large to be answered here. You are asking someone to explain how two random applications work. You cannot realistically expect such information from a technical forum. As I expalined before, you need to go and do the research for yourself. When you have specific questions come back here and people will try to help you. In the meantime you should also read http://www.codeproject.com/Messages/3137514/Forum-Guidelines-PLEASE-READ.aspx[^].
I was looking for suggestion what would be best approach in below scenario:
1. Have 3 spinners ("districts", "city", "shops").
2. Once user select an item from "districts" spinner, "city" spinner is populated and once city is selected "shops" could be selected. Now I have used a subclass of AsyncTask class to populate district spinner.
For populating other spinners "city" and "Shops", is writing separate subclass dedicated to each sinner the only option and update each spinners (which is a View) in each class's onPostExecute() method ? Is there any way to use a single subclass of AyncTask and use that for populating all "cascaded" spinner ? What could be best approach in such scenario.
Yah, Thanks Richard, I could figure out this. I noticed that the first param is an array of argument(varargs) in execute method in AsyncTask and that is something I could use for this purpose. I could just pass an indicator string just to differentiate and used switch-case in onPostExecution method and I could get it going today.
I will check with passing view id would help me better.
Hello. I am in the design process in creating a video chat application. I am trying to come up with the best route for the video transmission..being new to the mobile world I am wondering if there needs to be a 'middle-man' that is in charge of routing the data?
For instance, should I have each client hit a webservice that would be in charge of sending the data to the other client? Should I just have the clients connect directly to each other (if possible) and by pass a webservice?
Can anyone answer how apps like Periscope handles the transmission of its video?
Doing some more research it appears that we will need a 'Signaling Service' which will be responsible for transmissions of data. PubNub is one that I have found. So far I cannot find another way of doing it, in my app I was hoping to be able to have multi-user video chat..which I could but would have to pay for something like PubNub.
I have to work on an application in which we are getting list of orders(with all details and display_time) and we have to show them in list view, but the condition is we have to show particular order on their exact display_time.
For example below are some orders with display time:
order_id: 101 | display_time (hh:mm:ss): 09:10:00
order_id: 102 | display_time (hh:mm:ss): 09:30:00
Then the requirement is:
> We have to show the orders on list on exact their display time.
> All order should come instantly as they entered in database.
We have to show the orders on list on exact their display time.
It means that if I have an order that has the display_time="09:10:00", then It should be visible on list on exact 09:10:00 of device time, neither before not after of the display_time.
All order should come instantly as they entered in database
All order come form database, and order can be placed by website or by android application using APIs. I am thinking to use the Google Cloud Messaging to get instant orders, but the vison is not clear to me.
then It should be visible on list on exact 09:10:00 of device time, neither before not after of the display_time.
Makes no sense whatsoever.

Nor me, you need to go back and think about how you will get the information from the database to the Android device. And what happens if the device is not running the app at the time an order comes in?
