Question

I my application i am going to implement the Progress dialog till its getting loading. . .
The code is like:

copyFileFromAssetsToSDCard("Alone.mp4");
intent = new Intent(this,VideoPlayerController.class);
startActivity(intent);

So how to implement it ??
Thanks.

Code for the function is:

public void copyFileFromAssetsToSDCard(String fileFromAssets){
    AssetManager is = this.getAssets();
    InputStream fis;
    try {

        fis = is.open(fileFromAssets);
        FileOutputStream fos;

        fos = new FileOutputStream(new File(Environment.getExternalStorageDirectory(), fileFromAssets));
        byte[] b = new byte[8];
        int i;
        while ((i = fis.read(b)) != -1) {
            fos.write(b, 0, i);
        }
        fos.flush();
        fos.close();
        fis.close();
    } catch (IOException e1) {
        e1.printStackTrace();
    }
}

You can do like this,

Create an ArrayList<String> files = new ArrayList<String>(); and add all the files that you can to copy to SDCard like the below.

        files.add("test.png");
        files.add("icon.png");
        new myAsyncTask().execute(files);

Then you can just use this ArrayList object to pass to AsynTask and get it done.

private class myAsyncTask extends AsyncTask<ArrayList<String>, Void, Void>
    {
        ArrayList<String> files;
        ProgressDialog dialog;
        @Override
        protected void onPreExecute() {
            dialog = ProgressDialog.show(mainact.this, "Loading...", "");
        }
        @Override
        protected Void doInBackground(ArrayList<String>... params) {

            files = params[0];
            for (int i = 0; i < files.size(); i++) {
                copyFileFromAssetsToSDCard(files.get(i));   
            }
            return null;
        }
        @Override
        protected void onPostExecute(Void result) {
            dialog.dismiss();
        }

    }
