如果多次启动Android服务会怎样?

问题描述

如果我有以下代码:

Intent intent = new Intent(this,DownloadService.class);
for(int i=0;i<filesArray.length;i++){
     startService(intent);
}

在此代码中，DownloadService扩展了IntentService.

所以现在，当我调用startService(intent)时，这意味着每次调用startService(intent)时我都在启动新服务，或者这意味着DownloadService运行一次，然后每次我调用它只会传递具有不同startId的不同意图.

So now when I'm calling startService(intent) does that mean that I'm starting a new service every time startService(intent) is called or does that mean that DownloadService is run once and then each time I call startService(intent) it will just pass a different intent with a different startId.

这有意义吗?是哪种情况?

Does this make sense, and which one of these is the case ?

推荐答案

该服务仅在一个实例中运行.但是，每次启动服务时，都会调用onStartCommand()方法.

The Service will only run in one instance. However, everytime you start the service, the onStartCommand() method is called.
