Problem loading songs Prepare failed.: status =0x1

1

When calling MediaPlayer.Play(mysong); I get an exception “Java.IO.IOException: Prepare failed.: status=0x1”

I’ve tried several files…
In monogame pipeline tool I’ve tried .ogg files, .mp3 files, and with the mp3 file I tested the wma file it created and it was fine

Anyone know what causes this? Also, I checked the xnb files in hex editor and they all reference .wma files. I’ve checked to make sure the xnb and .wma files are making it to the android.bin/anyCPU/Debug/Content folder.

My emulater is Android 8.1(API Level 27 - Oreo) I’m using Visual Studio.
Your help is greatly appreciated.

not sure if it’s related, but the callstack looks like you’re calling .Play in LoadContent?

Just saying hello and welcome to the forums.

I don’t think it matters does it? I was following this tutorial which has the line to play in load content. Has something changed I. The library so that this is not okay now? FYI also used assets from this as well as tested with mp3s.

Hi Mr. Valentine. Thank you.

I don’t know, it can be completely fine, I just wondered if it was by purpose.

Have you tried it on a physical device?

So, I did test it with a windows app instead of android and it works. Is there some setting in the manifest I need to request to gain access to audio? I also tried setting timers and moving the play code, even retrying, in a loop but that didn’t work.

Update… The Mediaplayer still is not working in andoid… However, the SoundEffect is. I think this is a bug.

I’m experiencing the same issue with Xamarin.Android specifically not liking the MediaPlayer.Play from a Content Pipeline mp3 asset. Works fine with UWP. I’m using MonoGame.Framework.Android v3.7.1.189,

I’m running into this issue, suddenly none of my MonoGame.Android apps will play music and throw this error. Does anyone know the source of this problem, or how to solve it?

I reinstalled MonoGame and that has fixed the issue. I was monkeying around with the content pipeline awhile ago, that must’ve broken something :man_shrugging:
