Android——开机启动功能（Service和BroadcastReceiver）

BroadcastReceiver(广播接收器)：发出广播让服务器去接收

BootReceiver.java

package com.example.chenshuai.test321;

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

public class BootReceiver extends BroadcastReceiver {
    public BootReceiver() {

        Log.e("TAG","构造开机完成广播接收器");
    }

    @Override
    public void onReceive(Context context, Intent intent) {
        // TODO: This method is called when the BroadcastReceiver is receiving
        // an Intent broadcast.
        //throw new UnsupportedOperationException("Not yet implemented");

        //启动服务
        context.startService(new Intent(context,BootService.class));

        Log.e("TAG", "广播接收器自动启动Service");


    }
}

Service：接收广播传过来的意图

BootService.java

package com.example.chenshuai.test321;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.util.Log;

public class BootService extends Service {
    public BootService() {
    }

    @Override
    public IBinder onBind(Intent intent) {
        // TODO: Return the communication channel to the service.
        //throw new UnsupportedOperationException("Not yet implemented");

        return null;
    }

    @Override
    public void onCreate() {
        super.onCreate();

        Log.e("TAG","服务自动启动了");
    }
}

在manifest.xml中调至相同频率/同时设置权限

<!--接收开机完成的广播权限-->
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED"/>


 <service
            android:name=".BootService"
            android:enabled="true"
            android:exported="true" />

        <receiver
            android:name=".BootReceiver"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED"/>
            </intent-filter>
        </receiver>
