在Android手机或车机启动的过程中会触发一个Standard Broadcast Action

android.intent.action.BOOT_COMPLETED(只会触发一次),因此我们只需构建一个广播接收者来接收这个action来启动我们的Service即可。

（1）在Mainfest.xml中配置权限、注册register及service

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="对应你的service包名">
//监听开机的权限
    <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
    <application
        android:allowBackup="true"
        android:supportsRtl="true">

        <service
            android:name=".StartService"
            android:enabled="true"
            android:exported="true" />
            
        <receiver android:name="receiver.StartReceiver">
            <intent-filter android:priority="100">
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>
    </application>

</manifest>

（2）需要启动的Service

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


public class StartService extends Service {
    public static final String TAG = "startService";
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

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

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d(TAG, "service is started");
        return super.onStartCommand(intent, flags, startId);

    }

    @Override
    public void onDestroy() {

        super.onDestroy();
    }
}

（3）构建Register

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

import com.hryt.service.StartService;

public class StartReceiver extends BroadcastReceiver {
    public static final String TAG = "StartReceiver";
    public static final String ACTION ="android.intent.action.BOOT_COMPLETED";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG,"receiver broadcast "+intent);
        if (intent.getAction().equals(ACTION)) {
            context.startService(new Intent(context, StartService.class));
        }

    }
}
