Android应用后台保活

公司最近的新需求，需要实时动态的向后台上传经纬度，每隔10s上传一次，记录运行轨迹，尝试了多种办法都不行，只能用开启无声音乐来保活。

下面是service的主要代码

先注册一下：

<service
            android:name="com.common.x.areainspect.AreaInspectService"
            android:exported="true"
            android:priority="1000">
            <intent-filter>
                <action android:name="com.common.x.areainspect.AreaInspectService" />
            </intent-filter>
        </service>

import android.app.Notification;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.IBinder;
import android.util.Log;

import com.project.R;

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

public class AreaInspectService extends Service {
    private Timer timer;
    private long when = 1000 * 2; // 延迟2秒执行
    private long period = 1000 * 5; // 每次定位执行间隔
    private long periodAreaInspect = 1000 * 10; // 每次巡查执行间隔
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }
    /**
     * 定时定位
     */
    TimerTask timerTask = new TimerTask() {
        @Override
        public void run() {
            //在这里面定时传送数据
        }
    };
    @Override
    public void onCreate() {
        super.onCreate();
        timer = new Timer();
        // 启动定位
        timer.schedule(timerTask, when, period);
    }
    @Override
    public void onDestroy() {
        if (timer != null) {
            timer.cancel();
        }
        stopVoice();
        stopForeground(true);
        super.onDestroy();
    }
    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        PendingIntent notificationIntent = PendingIntent.getActivity(this, 0, new Intent(this, AreaInspectActivity.class), 0);
        Notification noti = new Notification.Builder(this)
                .setContentTitle("正在巡查")
                .setContentText("位置刷新中")
                .setSmallIcon(R.mipmap.ic_launcher)
                .setContentIntent(notificationIntent)
                .build();
        startForeground(123456,noti);
        start_mp3();
        return Service.START_STICKY;

    }
    private MediaPlayer mediaPlayer;

    //开始播放声音
    private void start_mp3() {
        try {
            mediaPlayer = MediaPlayer.create(this, R.raw.silent);//silent为无声音乐，网上搜索下载就可以
            mediaPlayer.start();
            mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                @Override
                public void onCompletion(MediaPlayer mp) {
                    mediaPlayer.start();
                }
            });

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

    //停止播放声音
    public  void stopVoice(){
        if(null!=mediaPlayer) {
            mediaPlayer.stop();
        }
    }
}

开启服务

Intent intent = new Intent(AreaInspectActivity.this, AreaInspectService.class);
startService(intent);

停止服务

Intent intent = new Intent(AreaInspectActivity.this, AreaInspectService.class);
stopService(intent);
