Android Tutorial select image from device and upload in server

well hi too all .
As the title suggests, I want to teach you how to upload photos
I had searched a lot about it myself and had not found any results. By changing other people's codes, I was able to get the answer and select the photo and send and save it to my host, which is Linux.
I will give you sample codes, if you have any questions, I am at your service
firest example cod for select image by library ContentChooser

    Dim PicChooser As ContentChooser
    PicChooser.Initialize("PicChooser")
    PicChooser.Show("image/*", "Select a pic")

Note that in order to get the address of a selected photo, you must use the method below that Eral took pains to use

Sub GetPathFromContentResult(UriString As String) As String
    If UriString.StartsWith("/") Then Return UriString 'If the user used a file manager to choose the image
    Dim Cursor1 As Cursor
    Dim Uri1 As Uri
    Dim Proj() As String = Array As String("_data")
    Dim cr As ContentResolver
    cr.Initialize("")
    If UriString.StartsWith("content://com.android.providers.media.documents") Then
        Dim i As Int = UriString.IndexOf("%3A")
        Dim id As String = UriString.SubString(i + 3)
        Uri1.Parse("content://media/external/images/media")
        Cursor1 = cr.Query(Uri1, Proj, "_id = ?", Array As String(id), "")
    Else
        Uri1.Parse(UriString)
        Cursor1 = cr.Query(Uri1, Proj, "", Null, "")
    End If
    Cursor1.Position = 0
    Dim res As String
    res = Cursor1.GetString("_data")
    Cursor1.Close
    Return res
    End Sub

ok
Well, now we have to use this method
The contentChooser library uses another method to get the result, which is as follows

Sub PicChooser_Result (Success As Boolean, Dir As String, FileName As String)
    If Success Then
        allpaths=Regex.Split("/",  GetPathFromContentResult(FileName))
        directionselectimage= GetPathFromContentResult(FileName).Replace(allpaths(allpaths.Length-1),"")
         File.Copy(directionselectimage,allpaths(allpaths.Length-1),File.DirRootExternal,allpaths(allpaths.Length-1))
 
   '    This code is for displaying the selected photo with imageview
   '     Dim bmp As Bitmap
   '     bmp.Initialize(directionselectimage, allpaths(allpaths.Length-1))
   '     imgviewpostupload.SetBitmap(bmp)

  Else
        If LastException.IsInitialized Then ToastMessageShow(LastException.Message, True)
    End If
End Sub

Well, now we go to the button to send information. Note: You can send unlimited information, that is, as you are sending the photo, you can also send other information. I will now give you the sample code. The type of sending other information is Get

  PNUpload.StartUpload("","",File.Combine(File.DirRootExternal,allpaths(allpaths.Length-1)), _
            "https:yourDomain?idmusic=1" ,"filename",1)
    ProgressDialogShow2("is uploading...",False)

Well, the information has been sent. Now we need to control the return information, add these codes to the end of your codes

Sub PNUpload_OnFileUploaded(ServerMessage As String,Tag As Object) 'Payami ke baadAz payan amaliat az PHP Echo mishe
    ProgressDialogHide
    
    Dim matn As String="missin complate"
    pnlboxpost.Visible=False
    Log(ServerMessage)
    Msgbox(matn,"ok")
End Sub
Sub PNUpload_OnError(ErrorMessage As String,Tag As Object)
    ProgressDialogHide
    
    Dim matn As String="error"&"later try again "
    Log(ErrorMessage)
    Msgbox(matn,"error")
End Sub

Now we go to php

<?php
 
if (isset($_FILES['filename'])){
    $file = $_FILES['filename'];
    $fileName = $file['name'];
    $filType = $file['type'];
    $fileTmp = $file['tmp_name'];
    $fileSize = $file['size'];
    $uploadOk = 1;
    $target = 'uploadimage/'; // folder name
    $newName = 'https:ayandehyafzararya.ir' . time();
   $idmusic=$_GET["idmusic"];

    //Check FileSize
    if ($fileSize > 700000) {
        $uploadOk = 0;
        echo  "You can upload up to 5 MB";
    }

    //if $uploadOk=1
    if ($uploadOk == 1){
        $ext = pathinfo($fileName, PATHINFO_EXTENSION);
        $target = $target . $newName . '.' . $ext;
        move_uploaded_file($fileTmp,$target);
        echo "ok";
    }
else{
        echo "error";
}
}
?>

This training was based on the fact that you are proficient in coding and it is a bit confusing for beginners. Please contact me if you have any questions.

You can skip using GetPathFromContentResult by copying the file to DirInternal or a writable location then upload from there.

Sub PicChooser_Result (Success As Boolean, Dir As String, FileName As String)
    If Success = False Then Return
    File.Copy(Dir, FileName, File.DirInternal, FileName)
End Sub

GetPathFromContentResult = broken code. Don't use it.

The user can choose a resource that is not stored on the device or that isn't stored as a file.

So what is your solution?

ok . That's right, I tried it and it gave me an error

If the InputStream is enough for what you need then use it, otherwise copy the file to XUI.DefaultFolder (=File.DirInternal).
