Shows how those clients can either start/stop it 197 with Context.startService and Context.stopService, or bind and call it with 198 Context.bindService and Context.unindService. 199 This also shows how you can simplify working 200 with a service when you know it will only run in your own process. The client 201 code for interacting with the service is in 202 <a href="LocalServiceActivities.html">Local Service Activities</a>.</dd> 203 204 <dt><a href="MessengerService.html">Messenger Service</a></dt> 205 <dd>Demonstrates binding to a Service whose interface is implemented with 206 the Messenger class. This is often an easier way to do remote communication 207 with a Service than using a raw AIDL interface. The client 208 code for interacting with the service is in 209 <a href="MessengerServiceActivities.html">Messenger Service Activities</a>.</dd> 210 211 <dt><a href="RemoteService.html">Remote Service Controller and 212 Remove Service Binding</a></dt> 213 <dd>Demonstrates starting a service in a separate process, by assigning 214 <code>android:process=":remote"</code> to the service in the 215 AndroidManifest.xml file. Shows how those clients can either start/stop it 216 with Context.startService and Context.stopService, or bind and call it with 217 Context.bindService and Context.unindService. 218 Binding is similar to the local service sample, 219 but illustrates the additional work (defining aidl 220 interfaces) needed to interact with a service in another process. Also 221 shows how a service can publish multiple interfaces and implement 222 callbacks to its clients.</dd> 223 224 <dt><a href="ServiceStartArguments.html">Service Start Arguments</a></dt> 225 <dd>Demonstrates how you can use a Service as a job queue, where you 226 submit jobs to it with Context.startService instead of binding to the service. Such a service 227 automatically stops itself once all jobs have been processed. This can be 228 a very convenient way to interact with a service when you do not need 229 a result back from it.</dd> 230 231 <dt><a href="ForegroundService.html">Foreground Service</a></dt> 232 <dd>Shows how you 233 can write a Service that runs in the foreground and works on both pre-2.0 234 and post-2.0 versions of the platform. This example will selectively use 235 the new foreground APIs that were introduced in Android 2.0 if they are 236 available.</dd> 237 238 </dl> 239 240 <h3 id="Alarm">Alarm</h3> 241 <dl> 242 <dt><a href="AlarmController.html">Alarm Controller</a></dt> 243 <dd>Demonstrates two ways you can schedule alarms: a one-shot alarm that 244 will happen once at a given time, and a repeating alarm that will happen 245 first at a given time and then continually trigger at regular intervals 246 after that. 247 <dl> 248 <dt>Code: 249 <dd> <a href="AlarmController.html">AlarmController.java</a> 250 <dd> <a href="OneShotAlarm.html">OneShotAlarm.java</a> 251 <dd> <a href="RepeatingAlarm.html">RepeatingAlarm.java</a> 252 <dt>Layout: 253 <dd> <a href="../../../../../../res/layout/alarm_controller.html"> 254 alarm_controller.xml</a> 255 </dl> 256 </dd> 257 258 <dt><a href="AlarmService.html">Alarm Service</a></dt> 259 <dd>Demonstrates how you can schedule an alarm that causes a service to 260 be started.
