Many times we want to cache the data locally in advance to save bandwidth. But recently, I encountered some minor problems when dealing with WeChat Mini Programs playing audio files cached locally, and then we need to adopt different playback strategies for Android and IOS.

First of all, if you use audio tags to play online audio files, if the server does not achieve breakpoint continuation, IOS will not be able to play, this should be noted.

For audio cached in Mini Program (audio saved by wx.saveFile (OBJECT)), IOS can only be played through the API for playing background music. Other playback methods have not been successfully practiced, while for Android, the internal audio context innerAudioContext object can be played. Give the code:

Var res = wx.getSystemInfoSync ()

If (res.platform = = 'ios') {

This.audio = wx.getBackgroundAudioManager ()

} else {

This.audio = wx.createInnerAudioContext ()

}

This.audio.title = "Music File"

This.audio.src = "local file address"

This.audio.play ()
