How To Upload Long Blob (image) To Mysql Database Using Java And Retrieve In Php?

I am working on a project where I need to upload images to the database and retrieve the same from database. I need the image to be uploaded from an android device using java. Here

Solution 1:

/**
*Get profile_pic*/publicfunctioncallmethod($userId){
$stmt = $this->conn->prepare("SELECT profile_pic FROM users WHERE unique_id=?");
$stmt->bind_param('s',$userId); 
//$result = mysql_query($query) or die(mysql_error()); //$photo = mysql_fetch_array($result); $stmt->execute();
$stmt->store_result();
$stmt->bind_result($profile_pic);
while ($stmt->fetch()) {
    echo"<img src='data:image/jpeg;base64,".$profile_pic."' />";
}
 //$obj->picture = base64_encode($profile_pic);//echo $obj;


}

ok try this code this.you don't need header("Content-Type: image/jpeg"); function. this are error in your php code. this code will create img tag with basc64.

now for android part.

change this in php.

while ($stmt->fetch()) {
    echo"<img src='data:image/jpeg;base64,".$profile_pic."' />";
}

to

while ($stmt->fetch()) {
    echo$profile_pic;
}

and this would be your android part.

byte[] decodedString = Base64.decode(strBase64, Base64.DEFAULT);
BitmapdecodedByte= BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
image.setImageBitmap(decodedByte);
