推荐答案

如果您谈论的是Android应用程序内存，

If you talking about Android Application Memory then,

ActivityManager.getMemoryInfo() 是我们用于查看整体内存使用情况的最高级别的API.

ActivityManager.getMemoryInfo() is our highest-level API for looking at overall memory usage.

进入较低级别，您可以使用

Going lower-level, you can use the Debug API to get raw kernel-level information about memory usage.

请注意，从2.0开始，还有一个API，

Note starting with 2.0 there is also an API, ActivityManager.getProcessMemoryInfo, to get this information about another process.

还可以解析/proc/meminfo命令.并获取内存信息的响应.

Also you can parse /proc/meminfo command. and get the response for memory information.

ActivityManager activityManager =  (ActivityManager) getSystemService(ACTIVITY_SERVICE);
MemoryInfo memoryInfo = new MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);
Log.i("memory free", "" + memoryInfo.availMem);
