We intend to support for Wi-Fi direct with our hardware on Android.
As per 
 http://www.sfonge.com/forum/topic/when-will-android-open-wi-fi-direct-api ,
Wi-Fi direct support may be added in Ice-cream Sandwich.

Existing Android Wi-Fi uses Linux wpa_supplicant for Station mode and
netd for Access point mode.

1. why would InputStreamReader returns null

Hi People;

I am trying to solve my problem about InputStreamReader returns
null..I have a Login screen which checks the configuration file.
and here is the configuration class

import java.io.*;

import j2me.microtools.BufferedReader;
import j2me.microtools.BufferedWriter;
import j2me.microtools.FileReader;
import j2me.microtools.FileWriter;

/** Configure helps the loading and saving of configuration data.
public class Configure
  protected void loadFile(String file,boolean define)
      if (file==null)
      BufferedReader in=null;
      FileInputStream fIn = null;
      String root = new String("//data//data//com.sam.nos//files//");
      InputStreamReader isr = null;

          //define null degilse buras android
          if(define != false){

                  fIn = Login.me.getApplicationContext().openFileInput(file);
                 // fIn = new FileInputStream(root + file);

                  isr = new InputStreamReader(fIn);

               in = new BufferedReader(isr);


As you can see i use the context of Login widget  I can see the fIn
constructs correct but isr is null..
What would be the problem.. any suggestion?



I've been toying with these two concepts for a while and was wondering
what the consensus is on how to handle accuracy changes.

I would like to be able to use the FINE but if not available use
COARSE. The issue is how to handle these two. I thought about using
two listeners and that seems like a good idea but it seems a bit of
overkill if there is a simpler method.

Any ideas? Code examples?

Thanks in advance.
