Looking at used and available memory and using this code, copied from here:
https://www.b4x.com/android/forum/threads/memory-usage.97349/
I get these values:
*** Service (starter) Create ***
Max Memory = 256 Mb
Total Free = 254 Mb
Total Memory = 7 Mb
Used Memory = 2 Mb
Free Memory = 5 Mb
after application fully loaded:
Max Memory = 256 Mb
Total Free = 250 Mb
Total Memory = 11 Mb
Used Memory = 6 Mb
Free Memory = 5 Mb
The last 4 values can vary by a few Mb, this is after the app is fully loaded.
Now, I am not sure what the exact meaning is of these 5 values.
Could somebody explain this to me?
