I'm getting the Failed to handle method call error when I click on one of the play mp3 buttons, such as 'Play dubstep.mp3'. But only when running in Android (either emulator or physical device):

The same action works fine in iOS.
I rolled back to 1.0.0 and experienced the same problem. I'm pretty sure I tried that version (1.0.0) in Android emulator before and did not experience this exception.
Dear @abacaj and @joelfaul, Sorry for the long answer, we do this project during our free time and university take all of it..
We will try to tackle this issue as soon as possible, hopefully in a few weeks as I need to reinstall and configure my workstation.
We will come back to you soon to resolve this problem, thanks for your understanding.
I just tried to recreate the issue and it works fine on Android. Did you try to update Flutter to the latest version?
Hi Lucas,
I just updated to your latest code as well as ensured Flutter is current and I am getting the same exception in the Android emulator. When I get a chance, I will try a completely clean get of your code just in case I have some residual thing in my copy affecting it.
Also, I accidentally created an empty pull request on your project. I closed it but I'm not sure how to delete it.
Joel

Hi Joel, no problem for the pull request.
Which version of the Android SDK are you running the application on? It might be related.
I've been using Nexus 5X API 27 for my emulator

Also, I have Android 8.1 (Oreo) installed and Android P Preview partially installed. So I guess it is building with Android 8.1, API level 27.

I just ran the application on API 27 and indeed an exception is raised.
I'll look into it and keep you updated.
