import java.io.IOException;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Toast;


public class MainActivity extends Activity {

    private static final int PICKFILE_RESULT_CODE = 2;
    private String FilePath;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void upLoadImage(View view) {

        Intent intent = new Intent(Intent.ACTION_GET_CONTENT); 
    intent.setType("*/*"); 
    intent.addCategory(Intent.CATEGORY_OPENABLE);

    try {
        startActivityForResult(
                Intent.createChooser(intent, "Select a File to Upload"),
                PICKFILE_RESULT_CODE);
    } catch (android.content.ActivityNotFoundException ex) {
        // Potentially direct the user to the Market with a Dialog
        Toast.makeText(this, "Please install a File Manager.", 
                Toast.LENGTH_SHORT).show();
    }

    }  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Fix no activity available
        if (data == null)
            return;
        switch (requestCode) {
        case PICKFILE_RESULT_CODE:
            if (resultCode == RESULT_OK) {
                 FilePath = data.getData().getPath();
                //FilePath is your file as a string
                Log.d("--------------", FilePath);
// print /external/images/media/2
                byte[] bytes=  getFileByte(FilePath);
                Log.d("--------------", ""+bytes);
            }
        }
    }

  private   byte [] getFileByte(String path){
         File file = new File(path);
            int size = (int) file.length();
            byte[] bytes = new byte[size];
            try {
// getting error on this line
                BufferedInputStream buf = new BufferedInputStream(new FileInputStream(file));
                buf.read(bytes, 0, bytes.length);
                buf.close();
            } catch (FileNotFoundException e) {
//catch here the error
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return bytes;
    }
}

What you get is not a file path for the file system but a media path in use by mediastore and others. In order to get a real filepath you have to invoke a cursor on the media store. You can find many example codes on this site.

There are permissions that you need to add to your android manifest although this may not be your only problem. Add:

<manifest ...>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
...
