【问题描述】：

有谁知道为什么我的安卓手机启动时我的服务无法启动？我正在尝试将我的服务链接到我的活动类，当活动崩溃时，服务将再次重新启动活动。我的服务类如下

public class Restarter extends Service {

@Override
public IBinder onBind(Intent intent) {
    return null;
}


@Override
public void onCreate() {
    super.onCreate();   
    Log.v("Restarter", "Restarter Created");
}

 @Override
    public int onStartCommand(Intent intent, int flags, int startId) 
    {
     Stamp_Client sc = new Stamp_Client();
        System.out.println("Restarter Service Started");
        while(true){
            System.out.println("Checking for crash...");
        int instance;
        instance = sc.nbInstances();
        if(instance == 0){
            Intent myIntent = 
           new Intent(Restarter.this,Stamp_Client.class);
            Restarter.this.startActivity(myIntent); 
        }
        try {
            Thread.sleep(10000);

        } catch (InterruptedException e) {

            e.printStackTrace();
        }

        // We want this service to continue running until it is explicitly
        // stopped, so return sticky.
        return START_STICKY;
    }

    }   }

我的清单如下

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="com.i2r.cas.mofa.main"

               android:configChanges="orientation|keyboardHidden">


   <service android:enabled="true" android:name=".Restarter" >
 <intent-filter>
    <action android:name="com.i2r.cas.mofa.main.Restarter">
    </action>
 </intent-filter>
  </service>    


  <receiver android:name=".StartAtBootServiceReceiver">
<intent-filter>
    <action android:name="android.intent.action.BOOT_COMPLETED">
    </action>
    <category android:name="android.intent.category.HOME">
    </category>
</intent-filter>
    </receiver>
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
   </application>

   </manifest>

有谁知道为什么在启动过程中没有调用它？谢谢！

在您的清单文件中，您以错误的方式声明了元素。

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>

<service android:enabled="true" android:name=".Restarter" >
  <intent-filter>
   <action android:name="com.i2r.cas.mofa.main.Restarter">
       </action>
    </intent-filter>
 </service>    
 <receiver android:name=".StartAtBootServiceReceiver">
    <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED">
                 </action>
             <category android:name="android.intent.category.HOME">
             </category>
       </intent-filter>
 </receiver>
</application>
</manifest>

在您的StartBootServiceReceiver 中调用 startService(intent of the service class) 方法
