How to get the currently available RAM in an Android device

See the English answer > how to get current memory usage in Android? 9 devices in which we enter the management application – > Run tab, and then at the bottom we will see used memory and amplifiers. Free memory changes their value

How do we code it into my application to display the same statistics?

thank you

resolvent:

ActivityManager.MemoryInfo

MemoryInfo mi = new MemoryInfo();
ActivityManager activityManager = (ActivityManager)getActivity(). getSystemService(Context.ACTIVITY_SERVICE);
activityManager.getMemoryInfo(mi);
long availableMegs = mi.availMem / 1048576L;

long percentAvail = mi.availMem / mi.totalMem;
