HTML5 audio blob would not play on Android -

-

I serve an audio file (WAV file containing a small uncompressed PCM) from my GAE app while using Bluetooth I am here. On the click event, I set the audio. Src and call audio.play () .

Now it's a weird part:

  • While working locally - it performs well on both iOS and Android.
  • After deploying GAE, it plays well on iOS - but not on Android !

No errors were shown - it just does not play anything, as far as I can tell from the GAE log, all the files have the audio file . In the case of Android, I can see a request from "Player / LG Player 1.0 for Android 4.4.2".

What's going on, or how to debug it?

According to the suggestion of Stuart Langley, tried to run the file from Google Cloud Storage


In that case, Android plays well, and IOS does not < / Strong> (gives an error from one side.)

Then a solution for me is storing files on cloud storage, and calling it to createGsBlobKey For it a blob. On behalf of the client, I check whether this is Android ( Navigator. EagerEgent.match (Android / I) ). In the case of Android, I have set the audio. Src in the cloud storage file, and in case of iOS I have set it to my servlet, which is BlobstoreService.serve Using the Blob Key I got the file from createGsBlobKey .

This is a cumbersome solution and I did not check other mobile OS that works for everyone, so if someone has a better solution then please let me know.

Most likely because of the spry response when serving a blob.

There is an issue tracker object about audio files not playing properly in some browsers.

There is a test web site that I have put together, while back describing the problem.

Workaround - You can put the file on cloud storage and then run it from there, unless you are concerned about hot-linking the file.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
