奇怪, `TOP`命令在 Debug 和 Release 环境下输出结果不一样

问题起因： 获取进程实时 CPU 占用率，还在看这方面东西，如有更好方法提供也非常感谢。

问题描述： Release 环境下，没有自身进程相关信息，即使去掉-o部分，出的也只有一条其他进程的信息。

测试设备： Google Pixel 3 Android 12 Android Studio Chipmunk | 2021.2.1 Patch 2

代码：

 mBinding.btnConfirmAttCpu.setOnClickListener { val runtime = Runtime.getRuntime() val cmd = arrayOf("sh","-c","top -n 1 -p ${Process.myPid()} -o PID,%CPU") val exec = runtime.exec(cmd) exec.inputStream.reader().apply { mBinding.displayCpuAttCpu.text = readLines().joinToString("${System.lineSeparator()}${System.lineSeparator()}") close() } exec.destroy() } 

Debug 输出:
