Subir imagen a server + php

[Alemanarg]

Hola, como estan??
Queria consultarles sobre los metodos usados para subir imagenes a un servidor.
Es mejor el metodo POST o con PHP?

Yo he usado lo siguiente, y todavia no logro hacerlo funcionar...alguno lo ha implementado de otra manera?

Código:

try {
		HttpClient httpClient = new DefaultHttpClient();  
		HttpContext localContext = new BasicHttpContext();  
		// here, change it to your php;  
		HttpPost httpPost = new HttpPost("http://www.xxxxxxxxxxxxxxx.com.ar/archivos/ImageUtil.php");  
		MultipartEntity entity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);  
		bitmap = BitmapFactory.decodeFile("test111.jpg");  
                Bitmap bmpCompressed = Bitmap.createScaledBitmap(bitmap, 640, 480, true);  
		ByteArrayOutputStream bos = new ByteArrayOutputStream();  
		bmpCompressed.compress(CompressFormat.JPEG, 100, bos);  
		byte[] data = bos.toByteArray();  
				  
		// sending a String param;  
		entity.addPart("myParam", new StringBody("my value"));  
		// sending a Image;  
		// note here, that you can send more than one image, just add another param, same rule to the String;  
		entity.addPart("myImage", new ByteArrayBody(data, "temp.jpg"));  
		httpPost.setEntity(entity);  
		HttpResponse response = httpClient.execute(httpPost, localContext);  
		BufferedReader reader = new BufferedReader(new InputStreamReader( response.getEntity().getContent(), "UTF-8"));  
		String sResponse = reader.readLine();  
				  
		} catch (Exception e) {  
				  Log.v("myApp", "Some error came up");  
				  }

Código PHP:

<?php
class ImageUtil{
    const uploadDir = "img";
    const allowedExtensions = "jpg, jpeg, gif, png";
    const maxSize = 2; //MB
    const maxWidth = 1024;
    const maxHeight = 1024;
    
    private static function validExtension($extension){
        $allowedExtensions = explode(", ", ImageUtil::allowedExtensions);
        return in_array($extension, $allowedExtensions);
    }
    
    private static function validSize($size){
        return $size<=ImageUtil::maxSize * pow(2,10);
    }
    
    private static function validDimensions($width, $height){
        return $width<ImageUtil::maxWidth && $height < ImageUtil::maxHeight;
    }
    
    private static function uploadedFile($file, $newFile){
        return move_uploaded_file($file, ImageUtil::uploadDir.'/'.$newFile);
    }
    
    public static function uploadImage($file, $newName){
        $extension = pathinfo($file['name']);
        $extension = $extension[extension];
        
        // check extension
        if (!ImageUtil::validExtension($extension))
            throw new InvalidExtensionException();
        
        // check dimensions
        list($width, $height, $type, $w) = getimagesize($_FILES['userfile']['tmp_name']);
        if (!ImageUtil::validDimensions($width, $height))
            throw new InvalidDimensionsException();
        
        // check size
        if (!ImageUtil::validSize($file['size']))
            throw new InvalidSizeException();
        
        // move to needed location
        if (!ImageUtil::uploadedFile($file['tmp_name'], $newName.".".$extension))
            throw new UnableToUploadException();
        
        return true;
    }
}
 
class InvalidExtensionException extends Exception {
    protected $message = 'Extension is invalid';   // exception message
}
class InvalidDimensionsException extends Exception {
    protected $message = 'Image dimensions are invalid';   // exception message
}
class InvalidSizeException extends Exception {
    protected $message = 'Size is invalid';   // exception message
}
class UnableToUploadException extends Exception {
    protected $message = 'Unable to upload file';   // exception message
}
?>
 

Muchas gracias!!
