@sugarlesscreator thank you

Please provide a simple text aia.
How the extension works does not seem self-explanatory.

@Shreyaa

DataSource : Using this block you can set the audio source

It does not work with an audio file from the assets, neither with Companion nor with the APK. With Companion it only works if the absolute path (to the ASD) is set.

It does not work with an audio file from the assets

i will fix that in next release

i am making it right now

thanks

Fine, so for now it only works with an absolute path to the external storage (including the ASD), e.g. like this:

[bodymindpower (Anke)]

Another thing: Your extension only declares RECORD_AUDIO in the Manifest, but not READ_EXTERNAL_STORAGE permission. So add this too.

Otherwise the user must add another extension or component, that declares it in the Manifest.

[bodymindpower (Anke)]

Btw, why does your extension declare RECORD_AUDIO?
I don’t think it’s necessary. Apart from that, you get a warning in the Play Store if this permission is requested / declared.

@bodymindpower

why does your extension declare RECORD_AUDIO ?

i was using media player class to get audio session ID to visualizer graph without this permission i was getting error so i added

[bodymindpower (Anke)]

Yes, checked, you actually need RECORD_AUDIO and READ_EXTERNAL_STORAGE permissions, the latter even when playing from the ASD. This should not be like that. It should work from the ASD without any storage permissions.

[bodymindpower (Anke)]

To get READ permission in the Manifest I added one of my extensions (or the File component).

Audio Visualizer extension 1.1

If the audio file is created by the app itself in one of the Shared folders, no storage permissions are required under Android 11+. Here are my blocks that should work with all Android versions if the sound is copied from the assets to one of the Shared folders (in my example /Music).

The block AudioVisualizer.AskForPermission does not trigger the permission granted event. So ask for it as shown in my blocks.

Audio Visualizer extension

I was almost to be more than happy if this extenssion could have an option to extract images from audio be from sdcard or online audio hosted in any platform server!
