Question

I haven’t started coding yet. I’m trying to figure out which libraries that is out there and what the API can offer first.

I need to download a lot of resources before starting my app. Basically I’m going to have a “SplashSreen” and a progressbar that shows which file being downloaded and the progressbar for the entire progress of downloading the x-number of resources.

After looking through some discussions and tutorials on the subject, it seems to me that AsyncTask will do the job. But it’s only possible to show the current progress for the current “object” being downloaded, and not for the entire queue.

Could anyone help me out here, give me some tutorials or something to dig into?

TBH; I’m not even sure if AsyncTask is what I’m looking for in this scenario. Basically I need something that can download resources, put in a queue, and let me know the progress of the entire queue, and which resource (name of it) being download at a certain time.

Thanks!

Of course an AsyncTask can do the job. Just put all your files in a asyncTask which display the progress.

class InitTask extends AsyncTask<Void, Integer, Boolean> {
    private List<String> mNbFiles;

    public InitTask(List<String> filesURL)
    {
        super();
        mFilesURL = filesURL;
    }

    @Override
    protected void onPreExecute() {
        //show and init your progress bar here...
        super.onPreExecute();
    }

    @Override
    protected Boolean doInBackground(Void... params) {

        for(int i = 0 ; i < mNbFiles.size() ; ++i){
            //download one file ...
            publishProgress(i);
        }
    }
}

I hope this will help you. Comment if you have any question.
