Power Platform Community Forum Thread Details

Hi Sik,

Thanks for your help.

I'm not sure what you mean by 'mode'. It's a canvas app that I've created on a Windows 10 laptop. To test it I use Power Apps on my Google Pixel 2 mobile phone which has the latest Android. Nearly all of my app works on the phone.
This is the code I use for my Save.
orAll(
CollectPics,
If(
PhotoAudio = false,
// Audio files.
// UploadAudioToSP.Run(Microphone1.Audio,FileName);
If(
varMobileDesktop = "Mobile",
// On a mobile device, such as an Android phone.
Collect(
CollectFileLinks,
{
FileLink: SubmitAudio.Run(
JSON(
{
FileName: FileName,
File: Microphone1.Audio
},
IncludeBinaryData
),
Comment,
AudioDuration
).sharepointfilelink,
PrimKey: lvPrimKey,
Comments: Comment,
SHIC_Nbr: txtQ1.Text,
Duration: AudioDuration,
PhotoOrAudio: "Audio"
}
),
// On a Windows 10 desktop PC.
Collect(
CollectFileLinks,
{
FileLink: SHIC_UploadAudio.Run(
FileName,
AudioDuration,
Audio,
Comment
).sharepointfilelink,
PrimKey: lvPrimKey,
Comments: Comment,
SHIC_Nbr: txtQ1.Text,
Duration: AudioDuration,
PhotoOrAudio: "Audio"
}
)
),
// Photo files. Add data to a Collection: CollectFileLinks.
Collect(
CollectFileLinks,
{
FileLink: SHIC_PhotosToSP.Run(
FileName,
Photo,
Comment,
lvPrimKey
).sharepointfilelink1,
PrimKey: lvPrimKey,
Comments: Comment,
SHIC_Nbr: txtQ1.Text,
Duration: 0,
PhotoOrAudio: "Photo"
}
)
)
);
When the code goes down the 'Mobile' part of my code it will only copy an audio file using the Microphone control. So the actual audio recording must come only from 'Microphone1.Audio'.
When the code goes down the 'Windows' part it takes the audio recording that has been saved to a collection.

After I record an audio recording, this is how I save it to a collection:
Collect(
CollectPics,
{
GroupNbr: lblGroupNbr.Text,
ItemNbr: lblItemNbr.Text,
Photo: TakenPhoto,
FileName: "Store_" & lblStoreNbr.Text & "SHIC_" & txtQ1.Text & "GrpID_" & lblGroupID.Text & "Item_" & lblItemNbr.Text & "Count_" & lblPicCount.Text + 1 & ".mp3",
Comment: txtPhotoComment.Text,
PhotoImage: Camera1.Photo,
Audio: TempAudioB64,
AudioDuration: Audio1.Duration,
PhotoAudio: false
}
);
// This Collect is for testing only.
// Collect(
// CollectAudio,
// {
// FileName: "Store_" & lblStoreNbr.Text & "SHIC_" & txtQ1.Text & "GrpID_" & lblGroupID.Text & "Item_" & lblItemNbr.Text & "Count_" & lblPicCount.Text + 1 & ".mp3",
// File: Microphone1.Audio
// }
// );
Reset(txtPhotoComment);
Set(
AudioSaved,
true
);
Reset(Audio1)

This collection saves all my media data - photos and audio recordings.

I want to be able to record and save more than ONE audio recording file to a collection on my phone. Then the user can assess whether they want to keep all of them or delete any before they are committed to being copied to a SharePoint Document Library.
The Power Apps error message is not up on my screen long enough to capture everything, but it had an error code: 502, BadGateway.
The Power Automate flow error from my 'Create file' into SharePoint step had an
Error: Action 'Create_file' failed
Error Details: InvalidTemplate. Unable to process template language expressions in action 'Create_file' inputs at line '1' and column '12005': 'The template language function 'base64ToBinary' was invoked with a parameter that is not valid. The value cannot be decoded from base64 representation.'.

From my limited understanding it has to do with the way Android (or iOS) mobile devices save audio file format as opposed to the way a Windows computer saves an audio file.

There are lots of YouTube videos explaining how to save ONE audio file at a time and they are always from a Windows 10 laptop/desktop PC. I can save more than ONE audio file from a collection to a SharePoint document library, but I cannot make it work on my Android phone.

I hope I've tried to give as much information as possible. Much appreciated for your help.
