I am not a programmer so maybe I overlooked something when trying my shinyMobile app on my Android device..
f7File functionality is not working on Android device when I try to upload an image of the phone.
IMG7456.JPG is correctly displayed when I use the function but the input$up is empty when I try to call it server-side.
server = function(input, output) {
data <- reactive(input$up)
observe(
print(data()$datapath)
)
output$theinput <- renderText(input$up$datapath)
}
shinyApp(ui, server)
`
In the MRE after uploading a file/picture/... you will get the path to this file displayed. If the path is not displayed, this means there is no path and so no input$up available and further actions on the input$up will not work.
So when you run the app locally on your laptop/PC you will always get a path and the f7File function works. When running the app in shinyapps.io as I did (MREforAndroid) and open the app on an Android device you are able to select files and images on your device. When running the MRE I noticed that uploading a picture taken via Whatsapp is possible but to remain on topic: uploading an image from Album is not possible.
I don't think it has something to do with the file size since I took an image of 3,18MB and this was also not possible.
