java - Fetch total Memory of Android Device -


i trying fetch total memory of android device. returns me 24gb. however, total internal memory of device 32gb.

i tried using ... 

public long getinternalfreespace()    {     //get free bytes...     long bytesavailable = stat.getblocksizelong() * stat.getavailableblockslong();     return bytesavailable; }

use this:

public static long getavailableinternalmemorysize() {     file path = environment.getdatadirectory();     statfs stat = new statfs(path.getpath());     long blocksize = stat.getblocksize();     long availableblocks = stat.getavailableblocks();     long size = availableblocks * blocksize;     long availableblocksinkb = size /= 1024;     long availableblocksinmb = availableblocksinkb /= 1024;     return availableblocksinmb; }

(int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
