Question

我已经在这里待了很长时间了，我不知道为什么它不起作用。我试图在设备启动时使用BroadcastReceiver启动服务。当设备启动时，它会崩溃并询问我是否已在AndroidManifest中注册了该活动。

我正在使用Genymotion模拟器，并尝试删除应用程序以及在Eclipse中清理项目。我也尝试将全名添加到android：name＆＃34; com.gordon.status.service.StartBackgroundSyncService，＆＃34;那也不起作用。

BroadcastReceiver：

public class AutostartReceiver extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent) 
    {
        Intent i = new Intent(context, StartBackgroundSyncService.class);       
        context.startService(i); 
    }
}

清单：

    <service
        android:name="service.StartBackgroundSyncService"
        android:enabled="true"
        android:exported="false"/>
    <service        
        android:name="service.LinkedInBackgroundService"
        android:enabled="true"/>
    <receiver android:name="receiver.AutostartReceiver"
              android:exported="false"
              android:enabled="true">
        <intent-filter>
            <action android:name="android.intent.action.QUICKBOOT_POWERON" /> <!--  For some HTC devices -->
            <action android:name="android.intent.action.BOOT_COMPLETED"></action>
        </intent-filter>
    </receiver>

服务（设备启动时应显示Hello）

public class StartBackgroundSyncService extends Service
{
    @Override
    public void onCreate()
    { 
        super.onCreate(); 

        System.out.println("HELLO=========================================================");
        System.out.println("=============================================================="); 
    }

    public int startCommand(Intent intent, int flags, int startId)
    { 
        return super.onStartCommand(intent, flags, startId); 
    }   

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

Answer 1

某处，而不是您在此处的代码中，您在指向startActivity()的{{1}}上呼叫Intent。由于StartBackgroundSyncService不是活动，因此失败。在这样的StartBackgroundSyncService上找到您要拨打startActivity()的位置，并将其更改为指向您应用中的实际活动。

尝试启动简单服务时，BroadcastReceiver在启动时崩溃
