Progress bar setProgress do not update Progress

[Hardik Trivedi]

Hi Friends,

I want to download a file from server and while downloading I want to show progress bar to display downloading pogress. I thought this is pretty much simple. But I am facing strange problem. Progress bar's setProgress method do not show the updated view of progress.

Below is my xml file

<ProgressBar android:id="@+id/downloading_progress_bar"
							android:visibility="invisible" 
							style="?android:attr/progressBarStyleHorizontal"
    						android:layout_width="wrap_content"
							android:layout_height="5dip"
							android:layout_marginTop="2dip"/>

Below is my java code...

downloading_progress_bar=(ProgressBar)findViewById(R.id.downloading_progress_bar);

ANd on click of a button I am starting the downloading...

else if(v==priceImage)
		{
			if(priceImage.getText().toString().equalsIgnoreCase("free"))
			{
				downloading_progress_bar.setVisibility(View.VISIBLE);
				
				downloading_progress_bar.setProgress(0);
				downloading_progress_bar.setMax(100);
				String downloadURL="http://watkinsbooks.cfmdeveloper.com/Books/eb_3/20_634436335548872500.epub";
				try 
		        {
		        	int count;
		        	
					URL url= new URL(downloadURL);
					URLConnection conexion = url.openConnection();
					conexion.connect();
					int lengthOfFile=conexion.getContentLength();
					InputStream input=new BufferedInputStream(url.openStream());
					
					OutputStream output=new FileOutputStream("/sdcard/sample_epub.epub");
					
					byte[] data =new byte[1024];
					long total=0;
					
					while((count=input.read(data))!=-1)
					{
						//Log.v("","Reading file...");
						Log.v(TAG,"-----------------------------------------");
						total+=count;
						Log.v(TAG,"Count = "+count);
						Log.v(TAG,"Total = "+total);
						int progress=(int)(total*100/lengthOfFile);
						Log.v(TAG,"Progress "+(int)(total*100/lengthOfFile));
						
						if(progress%10==0)
						{
							if(downloading_progress_bar.getProgress()!=progress)
							{
								downloading_progress_bar.setProgress((int)(total*100/lengthOfFile));
							}
						}
					
						output.write(data,0,count);
					}
					
					output.flush();
					output.close();
					input.close();
				} 
		        catch (Exception e) 
		        {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
}

It download's the file. But do not update the progress. Please Help...
