android开机自启动的后台Service的实现 .

在Manifest.xml文件中注册广播接收器，接收开机广播

[html] view plain copy print ?

<?xmlversion="1.0"encoding="utf-8"?>
<manifestxmlns:android="http://schemas.android.com/apk/res/android"
package="com.sensor.demo"
android:versionCode="1"
android:versionName="1.0">
<uses-sdkandroid:minSdkVersion="7"/>
<application
android:icon="@drawable/ic_launcher"
android:label="@string/app_name">
<serviceandroid:name=".SensorFunctionService"></service>
<receiverandroid:name=".BootCompletedReceiver">
<intent-filter>
<actionandroid:name="android.intent.action.BOOT_COMPLETED"/>
</intent-filter>
</receiver>
</application>
</manifest>

<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.sensor.demo"    android:versionCode="1"    android:versionName="1.0" >    <uses-sdk android:minSdkVersion="7" />    <application        android:icon="@drawable/ic_launcher"        android:label="@string/app_name" >                <service android:name=".SensorFunctionService"></service>                   <receiver android:name=".BootCompletedReceiver">              <intent-filter>                  <action android:name="android.intent.action.BOOT_COMPLETED" />              </intent-filter>          </receiver>      </application></manifest>

2.广播接收器接收到开机广播后启动Service

[java] view plain copy print ?

publicclassBootCompletedReceiverextendsBroadcastReceiver{
@Override
publicvoidonReceive(Contextcontext,Intentintent){
//TODOAuto-generatedmethodstub
IntentmIntent=newIntent(context,SensorFunctionService.class);
context.startService(mIntent);
}
}

public class BootCompletedReceiver extends BroadcastReceiver{@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stub        Intent mIntent = new Intent(context, SensorFunctionService.class);        context.startService(mIntent);}}

3.在Service里面做要做的事情

[java] view plain copy print ?

publicclassSensorFunctionServiceextendsService{
@Override
publicvoidonCreate(){
super.onCreate();
}
@Override
publicIBinderonBind(Intentarg0){
returnnull;
}
}

public class SensorFunctionService extends Service {       @Overridepublic void onCreate() {super.onCreate();}    @Overridepublic IBinder onBind(Intent arg0) {return null;}}

这个工程没有Activity，所有安装上以后也看不见。

要做的事情需要在重启机器后方能执行，因为Service的启动需要一个开机广播。
