I'm working with a application who use downloading mp3 files from web with URL and set them in folder created in external storage ,it was work with version 5 (lolipop) ,but when I test it with version 8 and 10 ,this not work!

this is downloading code:

String surl="https://media.sd.ma/assabile/recitations_7892537823/mp3/saad-el-ghamidi-001-al-fatiha-204-9244.mp3";

    try{
        URL url=new URL(surl);
        URLConnection conexion=url.openConnection();
      
        conexion.connect();
        int lenghtOfFile = conexion.getContentLength();
      
        File apkStorage = new File(
                Environment.getExternalStorageDirectory() + "/" +"apk_stokage");
        if (!apkStorage.exists()) {
            apkStorage.mkdir();
        }
        outputFile=new File(apkStorage,title+".mp3");
        if (!outputFile.exists()) {
            outputFile.createNewFile();
            Log.e("apk_stokage","File Created");
        }
        String path=Environment.getExternalStorageDirectory()+"/apk_stokage/";
        FileOutputStream fos = new FileOutputStream(outputFile);//Get OutputStream for NewFile Location
        InputStream is= new BufferedInputStream(url.openStream());

        byte[] buffer = new byte[1024];//Set buffer type
        int len1 = 0;//init length
        long total=0;
        while ((len1 = is.read(buffer)) != -1) {
            total+=len1;
            publishProgress((int)((total*100)/lenghtOfFile));
            fos.write(buffer, 0, len1);//Write new file
        }
      //  fos.flush();
        fos.close();
        is.close();

       // path2=outputFile.getPath();
    }catch(Exception e){
        e.printStackTrace();
    }

I wrote a library to do that with any file type and size. you can take a look to the library. The downloaded files will be saved on download directory. Any bug fixes and improvements are welcome
