Are context.startService() calls guaranteed to be

Question

Are context.startService() calls guaranteed to be aquired by the service in the same order they were sent?

consider in activity:

Intent intent;

intent = new Intent(MyIntents.ADD_BATCH_ACTION);
intent.putExtra(MyIntents.BATCH_ACTION_NAME, "Bake donuts");
startService(intent);

intent = new Intent(MyIntents.ADD_BATCH_ACTION);
intent.putExtra(MyIntents.BATCH_ACTION_NAME, "Make a coffee");
startService(intent);

intent = new Intent(MyIntents.ADD_BATCH_ACTION);
intent.putExtra(MyIntents.BATCH_ACTION_NAME, "Fetch coffee and donut to room 12");
startService(intent);

startService(new Intent(MyIntents.FLUSH_ADDED_ACTIONS));

Some action can hve much common work, I could optimize service if i were sure that they are executed in a batch.

Can I assume that service onStartCommand would be executed in the same order ?

While I think they happen to occur in order, AFAIK this is not documented behavior, and therefore I would not count upon it.

Then only call startService() once, with everything in your "batch". Intent extras support arrays for many types, so try packaging an array of extras instead of just one.
