Android Question Error loading bitmap : Initialize bitamp from input stream with php- mysql using OkhttpUtils2

M.LAZ · Dec 18, 2017

Hi ..
i searched a lot before posting my question here and read many threads ,, but i coudn't solve this error
i got this error when i trying to Initialize bitamp ..

how i save my picture in mysql using OkhttpUtils2 :

B4X:

Sub btnAddCategory_Click
Dim bm  As Bitmap
bm.Initialize(File.DirAssets,"food.png")
Dim ImgBytes() As Byte = Module.ImageToBytes(bm)
Dim su As StringUtils
Dim imgData As String = su.EncodeBase64(ImgBytes)
Http.Initialize("InsertCategory", Me)
Log("Insert imgData " & imgData)
Http.PostString("https://xxxxxx/newCategory.php", "Category="&Module.SQLiteEscape(txtCategoryName.EditText.Text.Trim)&"&"&"cateory_pic="&imgData)
    Http.GetRequest.Timeout = 30000
'    Http.GetRequest.SetHeader("User-Agent", "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0")
'Http.GetRequest.SetContentType("image/png") ' image/png  application/json
 
End Sub

and this is ImageToBytes sub :

B4X:

Public Sub ImageToBytes(Image As Bitmap) As Byte()
    Dim out As OutputStream
    out.InitializeToBytesArray(0)
    Image.WriteToStream(out, 100, "PNG") 'JPEG
    ''''''out.Close
    Return out.ToBytesArray
End Sub

and the imgData string in log :

java.lang.RuntimeException: Error loading bitmap.

in this line :

category_pic is a blob ..

i didn't think it's a corrupt image coz i got the same string ..
please any help or suggestions ?
thanks a lot..

KMatle · Dec 19, 2017

The Base64 string looks strange (first chars and spaces later). Are you using UTF8 encoding in your php script? How do you insert the pic?

M.LAZ · Dec 19, 2017

yes ,, i'm using UTF8 encoding...

my php script

B4X:

<?php

include ("db.php");

$con = mysql_connect($host,$user,$pw) or die(mysql_error());
mysql_select_db($db) or die(mysql_error());
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET NAMES 'utf8'");


        $Category = mysql_real_escape_string($_POST["Category"]);
       $category_pic= mysql_real_escape_string($_POST["cateory_pic"]);
       //echo $category_pic ;
        $q = mysql_query("SELECT * FROM categories WHERE category_name = '$Category'");
        $count = mysql_num_rows($q);
       //print json_encode ($count);
        if ($count == 0)
            {
              $res = mysql_query("INSERT INTO categories (category_name,category_pic,deleted) VALUES ('$Category','$category_pic','0')");
            print json_encode ("Inserted");
            }
        else
       {
            print json_encode ("Duplicated");
       }
mysql_close($con);

I still don't see it. Where is a call to Job.GetString? What are you doing with MyInputStream?

My guess is that mysql_real_escape_string breaks the base 64 string.

You can try to replace spaces with + when you receive the string.

M.LAZ · Dec 19, 2017

the first line retrieved the stored string ,, i found two spaces and one space in the blob field
as you mentioned
firstly i replaced 2 spaces with 1 space
secondly replaced 1 space with +

B4X:

           ImageData = colroot.Get("category_pic")
                    
                    ImageData=ImageData.Replace("  "," ")
                    ImageData=ImageData.Replace(" ","+")

M.LAZ · Apr 24, 2018

i use this code to replace spaces

B4X:

ImageData=ImageData.Replace(" ","+")

and i got this :

Looking around on the web, it looks like you have something called magic quotes enabled (this is a guess from my quick and dirty research). So
1) Disable magic quotes
2) Change the above code to

B4X:

$category_pic= mysql_real_escape_string(stripslashes($_POST["cateory_pic"]))

Without this modification, you are actually saving garbled data. mysql_real_escape_string without magic quotes makes the string supposedly save for MySQL. When you insert the string into MySQL, the escaping is undone and the unaltered data is stored in MySQL. With magic quotes on, you are actually escaping the magic quoted text and MySQL stores the magic quoted text instead of the unaltered string.

Hi @OliverA
i changed the above code and still got error ..
i read all your help in other threads but still i got the same error ..

here is my code to save the picture in mysql db

B4X:

Dim su As StringUtils
    Dim FileBuffer(0) As Byte
    Dim Out As OutputStream
    Out.InitializeToBytesArray(0)
   
    Dim xBitmap As Bitmap
    xBitmap.Initialize3(Module.viewAsBitmap( imgCategory))
    xBitmap.WriteToStream(Out,100,"JPEG")'PNG
    FileBuffer=Out.ToBytesArray
    Out.Close
    Dim B64String As String
    B64String=su.EncodeBase64(FileBuffer)
    Log("imgData before Insert=" & B64String)
    Http.Initialize("InsertCategory", Me)
    Http.PostString("https://www.xxxxx.com/newCategory.php", "Category="&Module.SQLiteEscape(txtCategoryName.EditText.Text.Trim)&"&"&"cateory_pic=" & B64String)
    Http.GetRequest.Timeout = 45000
''    Http.GetRequest.SetHeader("Content-Type", "application/json")
''    Http.GetRequest.SetContentType("application/json")
''    Http.GetRequest.SetContentEncoding("UTF-8")

and my php code to save the category:

B4X:

include ("db.php");

$con = mysql_connect($host,$user,$pw) or die(mysql_error());
mysql_select_db($db) or die(mysql_error());
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET NAMES 'utf8'");


        $Category = mysql_real_escape_string($_POST["Category"]);
        $category_pic= $_POST["cateory_pic"];  //mysql_real_escape_string()
        //$category_pic= mysql_real_escape_string(stripslashes($_POST["cateory_pic"]))
        //echo $category_pic ;
        $q = mysql_query("SELECT * FROM categories WHERE category_name = '$Category'");
        $count = mysql_num_rows($q);
        //print json_encode ($count);
        if ($count == 0)
            {
              $res = mysql_query("INSERT INTO categories (category_name,category_pic,deleted) VALUES ('$Category','$category_pic','0')");
            print json_encode ("Inserted");
            }
        else
        {
            print json_encode ("Duplicated");
        }
mysql_close($con);

to retrieve picture from db in PHP i use this code:

B4X:

<?php

include ("db.php");

$con = mysql_connect($host,$user,$pw) or die(mysql_error());
mysql_select_db($db) or die(mysql_error());
mysql_query("SET CHARACTER SET utf8");
mysql_query("SET NAMES 'utf8'");

$q = "SELECT category_id,category_name,category_pic FROM categories where deleted = '0' order by category_name ASC";
            $res1 = mysql_query($q);
         if (mysql_errno()) {
            header("HTTP/1.1 500 Internal Server Error");
            // echo $query.'\n';
            echo $res1.'\n';
            echo mysql_error();
        }
        else
        {
            $rows2 = array();
            while($rr = mysql_fetch_assoc($res1))
            //
                {
                if (array_key_exists('category_pic', $rr)) {
                $rr['category_pic'] = base64_encode($rr['category_pic']);
                }
            $rows2[] = $rr;
            }
           
            print json_encode($rows2);
            mysql_free_result($res1);
        }
mysql_close($con);
?>

and my b4a code to display the picture

that's all
i try a lot of codes but no way
i guess the problem from the content type of the image when saving it ..
i read this thread
https://www.b4x.com/android/forum/threads/string-to-bitmap.13116/#post-191524
and my question is how to add this content

B4X:

 Dim Logo = "data:image/png;base64,"

$rr['category_pic'] = base64_encode($rr['category_pic']);

Don't do this. You are already storing a Base64 encoded string in your DB. That code looks familiar. It is used if you store the image in binary format in the DB. Everything in my previous post about magic quotes is most likely hogwash (see signature).

M.LAZ · Apr 25, 2018

as Erel said
after more than 14 hours i got it ,, i used this code when retrieving image and before decoding string
B64String=B64String.Replace(" ","++")
B64String=B64String.Replace(" ","+")
but i replace every 2spaces with ++
and every space with +

now it works perfectly..
thanks @OliverA for your help..
