Updating the profile picture of a user

Question

I am making an application where I am using ImageLoading Framework for downloading the images from the server and put the URLs in the cache. Now I want the user's profile picture updating but even after updation of the profile pic on the sever it's not displaying in the application.

The app is showing the old profile pic of the User. Why this problem is arising and how can I troubleshoot?

Code for update onclick:

update_profile_pic.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
        String value_for_test="delete";
        Toast.makeText(getBaseContext(), "it works", Toast.LENGTH_SHORT).show();
        Intent i=new Intent(getApplicationContext(),ProfilePictureCaptureHomeActivity.class);
        i.putExtra("image",value_for_test);
        startActivity(i);

Profile Pic CaptureHome

DBAdapter db = new DBAdapter(getApplicationContext()); 
db.open();
if (null == phoneNumber) 
{ 
    Cursor c = db.getUserInfo();
    phoneNumber = c.getString(0);
    imageUrl = c.getString(1);
    
    System.out.println("the imageUrl is"+imageUrl);
    c.close(); 
}
setContentView(R.layout.profilepic_capture); 
if (null == imageUrl) 
{ 
    Cursor imageUrlObj = db.getUserInfo();
    imageUrl = imageUrlObj.getString(1);
    System.out.println("the imageurl is"+imageUrl);
    
    imageUrlObj.close(); 
}
db.close();

for updating the profile picture:

if(image!=null){
    Toast.makeText(getApplicationContext(), "Redirected", Toast.LENGTH_LONG).show();
    imageUrl=null;   
}
if(imageUrl != null)
{
    Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ListeningAndSharingHomeActivity.class);
    uploadimg.putExtra("phoneNumber", phoneNumber);
    startActivity(uploadimg);
}
else
{
    Log.v("ProfilePictureCaptureHomeActivity", "Staying Here");
}

_gallerybutton = (ImageButton) findViewById(R.id.btn_gallery);
_photobutton = (ImageButton) findViewById(R.id.btn_photo); 
System.out.println("here in popup phoneeeeee" + phoneNumber); 
System.out.println("here in flag************" + firstUpload);

_gallerybutton.setOnClickListener(new OnClickListener() { 
    @Override
    public void onClick(View v) {
        v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
        System.out.println("here in galleryyyyyyyyyy");
        Intent uploadimg = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromGallery.class);
        uploadimg.putExtra("phoneNumber", phoneNumber); 
        startActivity(uploadimg);
    }
});

_photobutton.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        v.performHapticFeedback(HapticFeedbackConstants.KEYBOARD_TAP);
        System.out.println("here in take piccccc");
        Intent capIntent = new Intent(ProfilePictureCaptureHomeActivity.this,ProfilePicFromCamera.class);
        startActivity(capIntent);
    }
});

have a look at this code.

private  String deleteExistingFile(String url , Context context) 
{


    String SaveFolderName = context.getFilesDir().getAbsolutePath()  + "/yourinternalmemoryfolder"; 

    String  str_randomnumber= url.substring(url.lastIndexOf("/") + 1);
    File wallpaperDirectory = new File(SaveFolderName);
        if (!wallpaperDirectory.exists())
        wallpaperDirectory.mkdirs();                
    String  Photo_ImagePath=SaveFolderName+"/" + str_randomnumber ;                 


    String result = "";
    System.out.println("file path to be deleted " + Photo_ImagePath);

         File f = new File(Photo_ImagePath);
          if (f.exists())
          {
              System.out.println(" EEEEEEEEEEXXXXXXXXIIIIISSSSSSSTTTTTTT ");
          try {
            if(f.delete() == true){
                result = "Success";
            }else{
                result = "Failure";
            }

          }

          catch (Exception e) {
            // TODO Auto-generated catch block
            e.printStackTrace();

            return "Error";
        }

          }

          System.out.println("deleting existing file " + result);
        return result;

}
