I followed Paul Culmsee's how to upload photos using flow and have a custom connector for flow which allows powerapps to call it using a http post trigger. When I look at the iOS and web client versions of powerapps, the http call has a body format like this
"$content-type": "multipart/form-data; boundary=\"969e7c17-5270-bc93-a78f-b9a71443f19c\"",
"$content": "LS05NjllN2MxNy01M<--content removed--> =",
"Content-Disposition": "form-data; name=\"file\"; filename=\"file_95de420d-d6e5-11eb-9652-ada88cafc5fd.jpg\"",
"$content": "/9j/4AAQSkZJRgABAQAASABIAAD/<--content removed-->"
where the large text above is the base64 encoded string for the file content.
But in the powerapps android client, the resulting http post format looks like
Where the large text above is a base64 encoded string which when decoded you can see is comprimised of a few things (see below).
Is there a way to get Android powerapps to call the http post method using the same format?
Have you also checked the following article?
Which also talks about the same issue, you may follow the steps there and try again.
Your issue here should be related with the Open API file, specially for the upload file definition part.
Would you please share your OpenAPI file for further analyze?
Thanks for the update.
Currently I have no idea, I will take some time to perform the test, and share you the results.
There might be some time delay.
Appreciate your patience and understanding.
