how can i r

Answer 1

public long getTotalMemory() {
    String str1 = "/proc/meminfo";
    String str2="";
    String[] arrayOfString;
    long initial_memory = 0, free_memory = 0;
    try {
        FileReader localFileReader = new FileReader(str1);
        BufferedReader localBufferedReader = new BufferedReader(
            localFileReader, 8192);
        for (int i = 0; i < 2; i++) {
            str2 =str2+" "+ localBufferedReader.readLine();// meminfo  //THIS WILL READ meminfo AND GET BOTH TOT MEMORY AND FREE MEMORY eg-: Totalmemory 12345 KB //FREEMEMRY: 1234 KB  
        }
        arrayOfString = str2.split("\\s+");
        for (String num : arrayOfString) {
            Log.i(str2, num + "\t");
        }
        // total Memory
        initial_memory = Integer.valueOf(arrayOfString[2]).intValue();
        free_memory = Integer.valueOf(arrayOfString[5]).intValue();

        localBufferedReader.close();
    } catch (IOException e) {
    }
    return ((initial_memory-free_memory)/1024);
}
