Fetch total Memory of Android Device

Question

I am trying to fetch the total memory of the Android device. But it returns me as 24GB. However, The total internal memory of the device is 32GB.

I tried using ...

public long getInternalFreeSpace()    {
    //Get free Bytes...
    long bytesAvailable = stat.getBlockSizeLong() * stat.getAvailableBlocksLong();
    return bytesAvailable;
}

Answer 1

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;
}
