memory info of a process in android

Question

I am trying to calculate the memory used by a single process in android, for that i am stuck at this point.

ActivityManager am=(ActivityManager)getSystemService(Context.ACTIVITY_SERVICE);
android.os.Debug.MemoryInfo[] mem=am.getProcessMemoryInfo(ProcessId);

From the above "MemoryInfo" what should i consider?

{mem.getTotalPss() or mem.getTotalPrivateDirty() or mem.getTotalSharedDirty()}

to get the amount of RAM used by the process.

Please help me with this. Thanks in advance.

mem.getTotalPss() gives you the total memory occupied by that process in Kb

Starting with marshmallow you have a few helper functions in MemoryInfo that you can query. it also can give you a list of parsed (and extra) info.

note that at least on s6 summary.graphics gives 0 always on everything. if a process is NOT a art/dalvik android process then it will simply give 0 on all the return strings. it will return them to this map though.

    int  pids[] =new int[1];
    pids[0]= pID;
    Debug.MemoryInfo [] mems1= am.getProcessMemoryInfo(pids);

    if(Build.VERSION.SDK_INT >= 23)
    if(mems1.length==1) {

        Debug.MemoryInfo meminfo=new Debug.MemoryInfo();

        Map<String, String> mems = mems1[0].getMemoryStats();

        for (Map.Entry<String, String> entry : mems.entrySet())
        {
            ret+=" k: "+entry.getKey()+":"+entry.getValue();
          //  addLineToSb(di, "m23: "+entry.getKey() + ":"+entry.getValue()+"kB");

        }


    }
