保证context.startService（）调用由以相同的顺序服务中获得性，他们被送到？ [英] Are context.startService() calls guaranteed to be aquired by the service in the same order they were sent?

问题描述

是context.startService（）调用保证通过他们被送到了相同的顺序服务中获得性？

考虑活动：

 意图意图;意图=新意图（MyIntents.ADD_BATCH_ACTION）;
intent.putExtra（MyIntents.BATCH_ACTION_NAME，烤甜甜圈）;
startService（意向）;意图=新意图（MyIntents.ADD_BATCH_ACTION）;
intent.putExtra（MyIntents.BATCH_ACTION_NAME，做一个咖啡）;
startService（意向）;意图=新意图（MyIntents.ADD_BATCH_ACTION）;
intent.putExtra（MyIntents.BATCH_ACTION_NAME，取咖啡和甜甜圈房间12）;
startService（意向）;startService（新意图（MyIntents.FLUSH_ADDED_ACTIONS））;
 

有些动作可以大大的hve共同的工作，我可以优化服务如果我是确保它们在批处理执行。

我可以假设，服务onStartCommand会以相同的顺序来执行？

问候，托梅克

虽然我觉得他们碰巧才能发生，AFAIK这不是记录的行为，因此，我不会在指望它。

然后只调用 startService（）一次，在你的一批的一切。意向额外支持数组为多种类型，所以尽量包装额外的阵列，而不是只有一个。

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.
