[Android] Audio duration = -1 when play a mp3 audio on website

I am facing an issue with mp3 duration, it doesn't work well on android. For example code, please refer attached files
This is output duration on Desktop and Android for same MP3 LINK
Desktop:
qml: Duration: 17604
Android: 
D libMP3Example_x86.so: qml: Duration: -1

I don't know why on Android, that duration is -1. In my project, I need correct value to use for Slider.
I tested on iOS, and it worked well, then it seems this happens only in android system.
It also works well if I use mp3 file as resource instead play online mp3.}}}}
