Solution 1:

You just check your Image_url ends with .png or not by using .endsWith(....) method of String like

if(image_url.endsWith(".png")){
//your image ends with .png

}else if(image_url.endsWith(".jpg")){
//your image  ends with .jpg
}

Solution 2:

You Can use String.endsWith method to do so see this link for better understanding.

String image_url = "http://testing-123.com/upload/products/" + pid +".png";

if(image_url.endsWith("png"))
{
  //do something
}
elseif(image_url.endsWith("jpg"))
{
  //do something
}
elseif(image_url.endsWith("bmp"))
{
  //do something
}

Hope it will help you.

Solution 3:

This is the best way, If you are selecting an image from device.

...

 /*
     * Get the file's content URI from the incoming Intent, then
     * get the file's MIME type
     */


Uri returnUri = returnIntent.getData();

String mimeType = getContentResolver().getType(returnUri);
