Android programming realizes the method of obtaining the memory surplus size and total size _android

The example in this article describes the way that Android programming realizes the amount of memory remaining and the total size. Share to everyone for your reference, specific as follows:

public class Meminfo {//Get available memory public static long getmem_unused (context Mcontext) {long mem_unused;  Get Activitymanager Activitymanager am = (activitymanager) mcontext.getsystemservice (Context.activity_service);
  Create Activitymanager.memoryinfo object Activitymanager.memoryinfo mi = new Activitymanager.memoryinfo ();
  Am.getmemoryinfo (MI);
  Get the remaining memory space mem_unused = mi.availmem/1024;
 return mem_unused;
  }//Get total memory public static long Getmem_tolal () {long mtotal;
  /proc/meminfo read the kernel information to explain String path = "/proc/meminfo";
  String content = null;
  BufferedReader br = null;
   try {br = new BufferedReader (new FileReader (path), 8);
   String Line;
   if (line = Br.readline ())!= null) {content = line;
  } catch (FileNotFoundException e) {e.printstacktrace ();
  catch (IOException e) {e.printstacktrace ();
    finally {if (br!= null) {try {br.close ();
    catch (IOException e) {e.printstacktrace (); }
   }
  }
  //beginindex int begin = Content.indexof (': ');
  endindex int end = Content.indexof (' k ');
  Intercept string Information content = content.substring (begin + 1, end). Trim ();
  Mtotal = integer.parseint (content);
 return mtotal;

 }
}

I hope this article will help you with your Android programming.
