测试apk-异常管控Sensor攻击者开发

1. 目的

基于《软件绿色联盟应用体验标准》中 Sensor 资源的定义，对 Sensor 后台持续使用的测试apk。旨在触发手机中异常功耗管控机制。

可以明确，不会触发Sensor的异常通知提醒，但是有日志输出

2. 测试步骤

H手机和T手机、其他手机进行安装该apk.
所有手机都需要设置应用为白名单。

2.1 手机白名单设置方法：

手机管家->应用启动设置：允许自启动、允许关联启动、允许后台启动

2.2 测试环境

除了白名单，其他无

2.3 运行本apk

灭屏后台的使用行为检测，直接打开应用运行，home键，退到后台，拔掉USB线，灭屏10分钟后，导出日志

3. apk 源码

本apk作用：后台无限制使用Sensor

3.1 UI

3.2 核心逻辑

3.2.1 MainActivity

package com.sufadi.blocksensorimport android.content.Intent
import androidx.appcompat.app.AppCompatActivity
import android.os.Bundleclass MainActivity : AppCompatActivity() {override fun onCreate(savedInstanceState: Bundle?) {super.onCreate(savedInstanceState)setContentView(R.layout.activity_main)startService(Intent(this, BlockSensorService::class.java))}
}

3.3.2 权限配置

    <!-- 前台服务属性权限 --><uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>

3.3.3 核心逻辑

任意注册一个Sensor，并后台常驻运行
