You can get the memory info using

MemoryInfo mi = new MemoryInfo();
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
activityManager.getMemoryInfo(mi);

and for a particular process use

activityManager.getProcessMemoryInfo(new int[]{process_ids});

which returns an array of memory information

getRunningAppProcesses will get you a list of PIDs, and then getProcessMemoryInfo will give you memory details about them.

MemoryInfo memory_info = new MemoryInfo();
ActivityManager activityManager = (ActivityManager) getSystemService(ACTIVITY_SERVICE);
activityManager.getMemoryInfo(mi);
double availableMegs = memory_info.availMem / 0x100000L;

//Percentage can be calculated for API 16+
double percentAvail = memory_info.availMem / (double)memory_info.totalMem * 100.0;

This will give you memory usage in percentage.
