Android电量优化之JobScheduler

android电量优化之jobscheduler。jobscheduler目前就我认知解决4个问题：

1.打包操作

2.充足电量、充电情况

3.wifi、移动数据情况

4.休眠

service

package com.example.demo;

import android.app.job.jobparameters;
import android.app.job.jobservice;
import android.content.context;
import android.net.connectivitymanager;
import android.net.networkinfo;
import android.util.log;

public class xjobservice extends jobservice {

    private static final string tag = "xbh";

    @override
    public boolean onstartjob(jobparameters params) {
        if (isnetworkconnected()) {
            log.i(tag, "我进行了网络请求");
            return true;
        }
        return false;
    }

    @override
    public boolean onstopjob(jobparameters params) {
        return false;
    }

    private boolean isnetworkconnected() {
        connectivitymanager connectivitymanager =
                (connectivitymanager) getsystemservice(context.connectivity_service);
        networkinfo networkinfo = null;
        if (connectivitymanager != null) {
            networkinfo = connectivitymanager.getactivenetworkinfo();
        }
        return (networkinfo != null && networkinfo.isconnected());
    }
}

注册，并且给予权限

提交任务

package com.example.demo;

import android.app.job.jobinfo;
import android.app.job.jobscheduler;
import android.content.componentname;
import android.content.context;
import android.content.intent;
import android.os.bundle;
import android.support.v7.app.appcompatactivity;

public class mainactivity extends appcompatactivity {

    private componentname servicecomponentname;

    @override
    protected void oncreate(bundle savedinstancestate) {
        super.oncreate(savedinstancestate);
        setcontentview(r.layout.activity_main);

        //开启服务
        intent intent = new intent(this, xjobservice.class);
        startservice(intent);

        servicecomponentname = new componentname(this, xjobservice.class);

        //提交10个任务
        submittask();
    }

    private void submittask() {
        jobscheduler scheduler = (jobscheduler) getsystemservice(context.job_scheduler_service);
        for (int i=0; i<10; i++) {
            jobinfo jobinfo = new jobinfo.builder(i, servicecomponentname)
                    .setminimumlatency(5000) //任务运行最少延迟时间
                    .setoverridedeadline(60000) //任务运行最晚期限
                    .setrequirednetworktype(jobinfo.network_type_any)//有网的时候
                    .build();

            if (scheduler != null) {
                scheduler.schedule(jobinfo);
            }
        }
    }
}
