Question

I have to an Activity in which I have to update the progress of the ProgressBar, with a value got from different class.

In download class I used this function to calculate progress..

public void publishDownloadProgress(long lengthoffile, long bytesDownloaded){
        mFileLength = lengthoffile;
        totalBytesDownloaded = bytesDownloaded;
        mProgress = ((totalBytesDownloaded*100)/mFileLength);    
    }

and this to get progress

public long getDownloadProgress(){
       return mProgress;
   }

But when I use getDownloadProgress(); in my Activity, I only get 0 which is understandable since it only gets it one time.

But what I like instead is a series of continuous progress values using which I want to update my ProgressBar, how to do that?

Answer 1

You should call getDownloadProgress() multiple times.

and set some time between two call.

You are getting zero because first time progress may be zero.
wait for some time 4ex Thread.sleep(50000);

then again call getDownloadProgress() you will get updated value
