Question

我从互联网上取样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

提前致谢

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。

您的包名称为package com.example.newtets;

并且清单需要package com.example.newtest;

所以修正错字，因为你正在传递com.example.newtets.BootCompletedIntentReceiver类

在android中启动后加载服务
