What happens to an Android app with background services in a multiple user environment?

Question

What happens when I have app A install it in two accounts account-a and account-b?

Assume I am using account-a and start the App (it has a background process).

Now I switch to account-b and start that app under that account.

Questions:

1. What happens to the App which was in account-a?
2. Will account-a app's background service be killed when i switch to account-b?
3. Will both account-a and account-b's background services be alive if i move from account-b to account-a ?

Answer 1

1. It depends on how do you handle the account a with the application. If you are keeping copy the account information in local SQLite db. it's will be saved and you can reuse it anytime.

2 & 3. Yes if you start the same service again , the running process will be interrupted in middle and killed. But you can always check whether the current service has completed it task. you can find info in this stackoverflow question
