Android ApiDemos示例解析(43)：App->Service->Remote Service Controller
Remote Service Controller 和使用Local Service的Android ApiDemo示例解析(40)：App->Service->Local Service Controller
都是使用Service的“Started” 模式，RemoteService在 AndroidManifest.xml中的定义如下：
<service android:name=”.app.RemoteService” android:process=”:remote”>
<intent-filter>
< !– These are the interfaces supported by the service, which
you can bind to. –>
<action android:name=”com.example.android.apis.app.IRemoteService” />
<action android:name=”com.example.android.apis.app.ISecondary” />
< !– This is an action code you can use to select the service
without explicitly supplying the implementation class. –>
<action android:name=”com.example.android.apis.app.REMOTE_SERVICE” />
< /intent-filter>
< /service>
RemoteService.Controller 中启动和停止Service的代码如下，和“Bound” Service模式相比要简单的多：
[java]
// Make sure the service is started. It will continue running
// until someone calls stopService().
// We use an action code here, instead of explictly supplying
// the component name, so that other packages can replace
// the service.
startService(new Intent(
"com.example.android.apis.app.REMOTE_SERVICE"));
... ...
// Cancel a previous call to startService(). Note that the
// service will not actually stop at this point if there are
// still bound clients.
stopService(new Intent(
"com.example.android.apis.app.REMOTE_SERVICE"));
// Make sure the service is started. It will continue running
// until someone calls stopService().
// We use an action code here, instead of explictly supplying
// the component name, so that other packages can replace
// the service.
startService(new Intent(
"com.example.android.apis.app.REMOTE_SERVICE"));
... ...
// Cancel a previous call to startService(). Note that the
// service will not actually stop at this point if there are
// still bound clients.
stopService(new Intent(
"com.example.android.apis.app.REMOTE_SERVICE"));
“Started” Service在启动之后会一直运行，直到调用stopService为止。因此在按“Start Service”后，在运行 Android ApiDemo示例解析(42)：App->Service->Remote Service Binding 来绑定这个RemoteService，由于RemoteService已经启动，你会发现例42中的Received from Service的初始值一般不会为1。
