title: How to load a lot of files from assets asynchronously?
body: <p>I know that it has similar topics. But in each topic we are open <code>InputStream</code> before task will be run and in new thread load data. But I have 90 asset files. Is this a single way to create 90 <code>AsyncTask</code>? Can I get access to main thread in <code>inBackground()</code> method to get assets and open new <code>InputStream</code>? Just in my case if I'll create 90 tasks I also need to synchronize their order of launch and finish. I need a point of synchronization where my <code>AsyncTask</code> will be wait the main thread.</p>
