Hi,
I was wondering about the best way to measure the remaining RAM on a
device. I have jusrt been using the emulator so far, and I connected
to the emulator using the "adb shell" command to get a Linux prompt
and used the vmstat command, in good old UNIX fashion, and got the
followoing output:
r b free mapped anon slab in cs flt us ni sy id wa ir
0 0 42236 21820 30700 3176 52 10 0 1 0 0 99 0 0
which I would interpret as 42236 kB of free RAM.
Then I tried to check this via a Java program and used the
MemoryInfo.availMem function as follows:
mgr = (ActivityManager) super.getSystemService
(Context.ACTIVITY_SERVICE);
memInfo = new ActivityManager.MemoryInfo();
mgr.getMemoryInfo(memInfo);
s = String.valueOf(memInfo.availMem);
and get a completely different result, it gives me about 88 MB
(88965120).
Which is the correct amount of remaining RAM in the device?
Thanks,
-Magnus
