Hi everyone,
I'm encountering an issue where the `Xrm.Device.pickFile` method is not opening the file manager on mobile devices.
I’m trying to use `Xrm.Device.pickFile` to allow users to select a file from their mobile devices, but the file manager doesn’t open when the method is called, however it does work in the Browser.
code snippet
Hello,
We finally have a solution. I reached out to the Microsoft PowerApps team, and they provided a solution. The documentation specifies that the "accept" option can only be audio, video, or image. With that said, we can omit this parameter, and it worked. Here’s the updated code:
Xrm.Device.pickFile({
// Maximum size of the file to be picked in bytes (example: 5 MB)
maximumAllowedFileSize: 5242880,
// Allow picking multiple files
allowMultipleFiles: true
}).then((e) => console.log("success"), (e) => console.warn(e));
Thank you for your follow-up on this issue. I wanted to share my findings. The failure occurs only in the Mobile app, not in the client browser. After some investigation, I couldn't find a definitive solution. However, I experimented with other methods like `captureImage` and `captureVideo`, which both worked.
To address the issue, I defined a variable as follows:
var isMobile = Xrm.Utility.getGlobalContext().client.getClient() === "Mobile";
Then, I set up my options object like this:
var pickFileOptions = isMobile ? {} : {
maximumAllowedFileSize: 5242880,
accept: ["*/*"],
allowMultipleFiles: true
};
This approach worked and allowed me to select only one file. My question now is whether there to predefine an object for the mobile app that I can pass.
Interesting. The documentation says that method is supported for web and mobile clients.
Are you in the mobile app or mobile browser when this error happens?
Do you get a return in the error handler of your async function that might help shed some light on this?
Thank you very much for your input, however, this is not a custom control, it's purely js where the method is triggered on an on-change event, and the dialog is supported to popup. I have been able to get the captureimage method to work with no problems but no issue when the pickfile method would not.
Sure -
In the ControlManifest.Input.Xml file, you will find the input manifest ready for you to customize your control. Right after the <resources/> node, you will find a commented out section for <feature-usage> which should look like this:

<uses-feature name="Device.captureAudio" required="true" />
<uses-feature name="Device.captureImage" required="true" />
<uses-feature name="Device.captureVideo" required="true" />
<uses-feature name="Device.getBarcodeValue" required="true" />

<uses-feature name="Device.pickFile" required="true" />
<uses-feature name="Utility" required="true" />
<uses-feature name="WebAPI" required="true" />
</feature-usage>
-->
To use any of those features, you need them to be uncommented in the manifest (this is a way of telling the app registration that you will be using capabilities that might require user permission or admin permission). In your case, all you need to do is swap out that commented block with something like this:
<feature-usage>
<uses-feature name="Device.pickFile" required="true" />
</feature-usage>
