Hi, there so i tried this example to download a image from server and save it to the local. This Works fine on laptop. But test the same thing on my phone it doesn't save the photo to the path I given. What to do? can anybody please help.

Page{ id: app FileFolder { id: fileFolder url: "assets/media_images" } //Downloads an image from the web NetworkRequest { id: networkRequest url: "http://appstudio.arcgis.com/images/index/introview.jpg" responsePath: fileFolder.path +"/appstudio.jpg" property url imagePath: responsePath onReadyStateChanged: { if (readyState == NetworkRequest.DONE) { image.source = "assets/media_images"+"/appstudio.jpg"; } } onError: { console.log(errorText + ", " + errorCode) //On failure, don't use the local copy image.source = "" } } ColumnLayout { spacing: 20 Button { id:download text: "Download Request (Download Image)" Layout.margins: 2 Layout.fillWidth: true onClicked: { networkRequest.send({f:"json"}); } } Image { id: image Layout.margins: 10 Layout.preferredWidth: 250 Layout.preferredHeight: 200 } } }

@x_d

Can you try changing the FileFolder section of the code?

FileInfo { id: destData path: "~" }

I think it is related of this change, https://community.esri.com/t5/arcgis-appstudio-blog/appstudio-and-android-10-scoped-storage-changes/ba-p/896653

Thank you,

Erwin

@ErwinSoekianto Thanks for the reply. So I gone through the documentation the scoped storage changes. and applied the path as mentioned there. But still it's not working the image gets disappeared. On appstudio player it's working fine but when i made a build for testing then it gets disappeared
