android开发之内存CPU监控
cpu，内存监控作为android性能测试的一部分，在日常工作中使用也比较频繁，一般测试人员都是直接adb命令输出结果或者android studio上查看内存,Cpu的趋势，再深入一点就是性能分析定位了。由于本人水平有限，就先分享个android apk 监控指定应用的cpu和内存。先附上两张效果图：
原理如下
输入需要监控的应用包名，输入监控的间隔时间，输入监控的总时间，点击监控就会执行监控命令，点击监控统计会在图标显示各项参数的最大值，最小值，平局值。点击监控详情会跳转到新的界面，展示详细的监控参数
代码如下
1.先在manifest文件加上如下权限
