Android : Downloading an image into internal storage and reading it in android

I am trying to download an image from url and i want to display it in an imageview.My code is as follows:

package com.example.imageinternalstorage;

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;

import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;

public class MainActivity extends Activity {
Button btnstoreinternal,btnloadfrominternal;
ImageView iv_category;
boolean download_success;
String URL_image="http://footballultimate.com/storelocator/resource/uploads/";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        btnstoreinternal=(Button) findViewById(R.id.btnstoreinternal);
        btnloadfrominternal=(Button) findViewById(R.id.btnloadfrominternal);
        iv_category=(ImageView) findViewById(R.id.iv_category);
        btnstoreinternal.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                download_success=downloadFile(URL_image+"Hospital.png");
                if(download_success==true)
                {
                    Toast.makeText(getApplicationContext(),"Download success",Toast.LENGTH_LONG).show();
                }
                else
                {
                    Toast.makeText(getApplicationContext(),"Download failed",Toast.LENGTH_LONG).show();
                }

            }
        });
        btnloadfrominternal.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                iv_category.setImageBitmap(getImageBitmap(MainActivity.this,"Hospital.png"));

            }
        });
    }

    public boolean downloadFile(final String path)
    {
        try
        {
            URL url = new URL(path);

            URLConnection ucon = url.openConnection();
            ucon.setReadTimeout(5000);
            ucon.setConnectTimeout(10000);

            InputStream is = ucon.getInputStream();
            BufferedInputStream inStream = new BufferedInputStream(is, 1024 * 5);

            File file = new File(MainActivity.this.getDir("filesdir", Context.MODE_PRIVATE) + "/Hospital.png");

            if (file.exists())
            {
                file.delete();
            }
            file.createNewFile();

            FileOutputStream outStream = new FileOutputStream(file);
            byte[] buff = new byte[5 * 1024];

            int len;
            while ((len = inStream.read(buff)) != -1)
            {
                outStream.write(buff, 0, len);
            }

            outStream.flush();
            outStream.close();
            inStream.close();

        }
        catch (Exception e)
        {
            e.printStackTrace();
            return false;
        }

        return true;
    }

    public Bitmap getImageBitmap(Context context,String name){
          try{
            FileInputStream fis = context.openFileInput(name);
                Bitmap b = BitmapFactory.decodeStream(fis);
                fis.close();
                return b;
            }
            catch(Exception e){
            }
            return null;
        }
}

When i click the first button the download is shown as successfull.But when i click the second button to display the image in the imageview nothing happens.So can anyone give me a replacement code for the retrival code from memory:

public Bitmap getImageBitmap(Context context,String name){
          try{
            FileInputStream fis = context.openFileInput(name);
                Bitmap b = BitmapFactory.decodeStream(fis);
                fis.close();
                return b;
            }
            catch(Exception e){
            }
            return null;
        }

The code for dowloading is:

public boolean downloadFile(final String path)
    {
        try
        {
            URL url = new URL(path);

            URLConnection ucon = url.openConnection();
            ucon.setReadTimeout(5000);
            ucon.setConnectTimeout(10000);

            InputStream is = ucon.getInputStream();
            BufferedInputStream inStream = new BufferedInputStream(is, 1024 * 5);

            File file = new File(MainActivity.this.getDir("filesdir", Context.MODE_PRIVATE) + "/Hospital.png");

            if (file.exists())
            {
                file.delete();
            }
            file.createNewFile();

            FileOutputStream outStream = new FileOutputStream(file);
            byte[] buff = new byte[5 * 1024];

            int len;
            while ((len = inStream.read(buff)) != -1)
            {
                outStream.write(buff, 0, len);
            }

            outStream.flush();
            outStream.close();
            inStream.close();

        }
        catch (Exception e)
        {
            e.printStackTrace();
            return false;
        }

        return true;
    }
