如何以编程方式确定Android上已安装的音频应用程序

Question

I'm trying to programmatically determine what audio applications are installed on an Android phone. I'm able to enumerate all the installed applications, but don't yet see a way to figure out which ones are capable of playing audio? What property of the application would have to queried to determine if is capable of playing audio?

Thanks in advance.

You'll probably want to [queryIntentActivites][1] with an ACTION_VIEW Intent with the MIME type specified as whatever form of audio you're playing.
