Android 开机自动启动一个Service 附源码

 

                 Android 开机自动启动一个Service

 

一、Google在更新Android8.0后对Service的权限越发收紧。导致目前想要启动服务必需实现服务的前台化，打开应用才能顺利启动service，否则在服务启动5秒后，系统将自动报错，会弹出一个提示窗口。实际测试得系统的app才能启动service。

 

二、android studio demo源码测试。

      1、添加权限，接受开机完成广播，一定的增加android:persistent="true"属性，AndroidManifest.xml源码如下

  2、接受广播处理文件，BootBroadcastReceiver.java

package com.example.giadawatchdog;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class BootBroadcastReceiver extends BroadcastReceiver {
    private static final String TAG ="WATCHDOG BROAD";
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.d(TAG, "onReceive !!");
        if (intent.getAction().equals("android.intent.action.BOOT_COMPLETED"))
        {
            Intent bootServiceIntent = new Intent(context, WatchdogService.class);
            Log.d(TAG, "onReceive BOOT_COMPLETED!! ");
            context.startService(bootServiceIntent);//startForegroundService
            //context.startForegroundService(bootServiceIntent);//startForegroundService
        }
    }
}

3、添加service WatchdogService.java文件。

package com.example.giadawatchdog;

import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.Service;
import android.content.Intent;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.os.IBinder;
import android.util.Log;

import java.util.Timer;
import java.util.TimerTask;

public class WatchdogService extends Service {
    private static final String TAG ="WATCHDOG SERVICE";
    private Timer timer = null;
    private  int count=0;
    @Override
    public IBinder onBind(Intent intent) {
        Log.d(TAG, "onBind !!");
        return null;
    }
    @Override
    public void onCreate() {
        super.onCreate();
        Log.d(TAG, "onCreate !!");
        timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run() {
                count++;
                Log.d(TAG, "timer 200ms !!count="+count);
            }
        }, 1000,200);
    }

    @Override
    public void onStart(Intent intent, int startId) {
        super.onStart(intent, startId);
        Log.d(TAG, "onStart !!");
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "onDestroy !!");
    }
}

   4、一定是系统app才可以，adb push到system/app/目录下。

   5、运行结果如下：

   6、开机自动会运行该app
