How to get total RAM size of a device?

Question

I want to get full RAM size of a device. memoryInfo.getTotalPss() returns 0. There is not function for get total RAM size in ActivityManager.MemoryInfo.

Answer 1

You can get the total RAM size by using this code:

var activityManager = GetSystemService(Activity.ActivityService) as ActivityManager;
var memoryInfo = new ActivityManager.MemoryInfo();
activityManager.GetMemoryInfo(memoryInfo);

var totalRam = memoryInfo.TotalMem / (1024 * 1024);

If the device has 1GB RAM, totalRam will be 1000.
