在android中启动后加载服务

Question

我从互联网上抽取了一个样本来实现在手机启动后自动启动的服务。但应用程序显示错误。请帮我解决问题

在此先感谢

xml文件

<manifest xmlns:android="http://schemas.android.com/apk/res/android" 
package="com.example.newtest" 
android:versionCode="1" 
android:versionName="1.0"> 

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/> 
<application> 
    <receiver android:name="com.example.newtest.BootCompletedIntentReceiver" 
         android:permission="android.permission.RECEIVE_BOOT_COMPLETED"> 
     <intent-filter> 
      <action android:name="android.intent.action.BOOT_COMPLETED" /> 
     </intent-filter> 
    </receiver> 
    <service android:name="com.example.newtest.BackgroundService"/> 
</application> 
</manifest> 

广播接收器类

package com.example.newtest; 

import android.content.BroadcastReceiver; 
import android.content.Context; 
import android.content.Intent; 

public class BootCompletedIntentReceiver extends BroadcastReceiver { 

@Override 
public void onReceive(Context context, Intent intent) { 
    if ("android.intent.action.BOOT_COMPLETED".equals(intent.getAction())) { 
      Intent pushIntent = new Intent(context, BackgroundService.class); 
      context.startService(pushIntent); 
    } 
} 
} 

服务类

package com.example.newtest; 

import android.app.Service; 
import android.content.Intent; 
import android.os.IBinder; 
import android.widget.Toast; 

public class BackgroundService extends Service { 

@Override 
public IBinder onBind(Intent intent) { 
    // TODO Auto-generated method stub 
    return null; 
} 

@Override 
public void onCreate() { 
    Toast.makeText(this, "OK", Toast.LENGTH_LONG).show(); 
    super.onCreate(); 
} 

} 

logcat的

Answer 1

很简单。

你包的名字是package com.example.newtets;

和清单预计package com.example.newtest;

所以固定错字，因为你传递com.example.newtets.BootCompletedIntentReceiver类，而不是
