Fun fact: Since Android Nougat apps cannot get the PID of other apps. This makes displaying the Memory info for apps other than Floating Info itself impossible. All other functionality will still work.

Floating Info is an Android application that displays the following in a system overlay window:

The application name, package name and process id (except on Nougat+) of the application which is currently in the device's foreground

The Global CPU utilisation with a per-core breakdown - This is not foreground application specific.

Memory usage breakdown for the currently foregrounded process - except on Nougat+ (read the notes for the caveats).

Netork information like connection type, proxy status and IP address(es). Both IPv4 and IPv6

Notes and Caveats

---

* The application will show the memory allocation of the currently foregrounded process which it gets by getting the Process Id of the currently foregrounded activity. This means that if an application has spawned multiple processes, this application will only show the memory utilisation of the main process.

* The Memory information displayed come via a Debug.MemoryInfo object, while using reflection to expose a number of hidden fields.

* Data updates happen approximately every 1 second.

Android Memory Usage

Memory management on Android is pretty complex and the easiest way to get started with understanding it is reading this article (https://developer.android.com/tools/debugging/debugging-memory.html) - especially the "Viewing Overall Memory Allocations" section.

有趣的事实：由于Android应用牛轧糖不能得到其他应用程序的PID。这使得显示比浮动信息本身不可能其他应用程序的内存信息。所有其他功能仍然有效。

浮动信息是一个Android应用程序，显示在系统覆盖窗口如下：

该应用程序的名称，包装名称和进程ID（除牛轧糖+）的应用程序这是目前在该设备的前景

全局CPU使用率与每个芯击穿 - 这不是特定前台应用程序。

内存使用击穿当前前景化进程 - 除了在牛轧糖+（阅读有关注意事项的提示）。

Netork信息，如连接类型，代理状态和IP地址（ES）。 IPv4和IPv6

注释和注意事项

---

*应用程序会显示当前前景化的过程，它会通过获取当前前景化活动的进程标识的内存分配。这意味着，如果一个应用催生了多个进程，这个应用程序将只显示主进程的内存利用率。

*记忆显示的信息通过Debug.MemoryInfo对象来了，而使用反射来揭露了一些隐藏字段。

*数据更新大约发生每隔1秒。

Android上的内存管理是相当复杂的，上手理解它是看完这篇文章（https://developer.android.com/tools/debugging/debugging-memory.html）最简单的方法 - 尤其是“看总体内存分配“ 部分。
