Android: wait in each loop iteration until I return from an activity that is started inside each loop...
I have started to learn Android and I want to achieve the following: I have a loop and in each iteration I start an activity. I want to wait until I get back from that activity (that I start in each iteration) before doing the next loop iteration and start an activity again, and so on.
I have seen that I can obtain a result from an activity ( RESULT_OK if the activity worked properly):https://developer.android.com/training/basics/intents/result , I guess I may have to use that functionality, but still I do not know how to wait until I get the RESULT_OK from the activity (Maybe I am wrong and Idon't have to get the result from the started activity, as I said I am a beginner).

Why do you want to do this? Why can't you just start the firstActivitywithstartActivityForResultand then when you return inonActivityResult, take next item in the list andstartActivityForResult, rinse repeat? The previousActivitywhere you've started your for-loop will be paused when a newActivityis started and so if you really want to use a for-loop, you need to store the state of the for-loop (the state in this case could be the index of what item you're iterating over). Have a look here: developer.android.com/guide/components/activities/…
