I want to automatically upload files to server after every captured, I zip them them, now I want to to send them to the sever. I used a on-click for user to click a button before they can upload it worked well, now I want to eliminate the on-click of a button to send to sever.

My code

TextView messageText;
   Button uploadButton;
   int serverResponseCode = 0;
   ProgressDialog dialog = null;
       
   String upLoadServerUri = null;
    
   //**********  File Path *************//
   final String uploadFilePath = "/mnt/sdcard/";
   final String uploadFileName = "my files";
    
   @Override
   public void onCreate(Bundle savedInstanceState) {
        
     /*  super.onCreate(savedInstanceState);
       setContentView(R.layout.activity_upload_to_server);
         */
       uploadButton = (Button)findViewById(R.id.uploadButton);
       messageText  = (TextView)findViewById(R.id.messageText);
        
       messageText.setText("Uploading file path :- '/mnt/sdcard/"+uploadFileName+"'");
        
       //************* Php script path ****************//*
       upLoadServerUri = "to here m uploading";
       //************* Php script path ****************//*
        
       uploadButton.setOnClickListener(new OnClickListener() {            
           @Override
           public void onClick(View v) {
                
               dialog = ProgressDialog.show(UploadService.this, "", "Uploading file...", true);
