I have image URLs for JPEG, GIF and PNG files. I want to check whether the images in those URLs are smaller than a specific size or not.
On the basis of that I want to download the image.
There ImageIO library in java for that but that's in the AWT library, I need something for Android.
You can get image size easily using URLConnection method getContentLength()
URL url = new URL("https://www.google.com.pk/images/srpr/logo4w.png");
URLConnection conn = url.openConnection();
// now you get the content length
int contentLength = conn.getContentLength();
// you can check size here using contentLength
InputStream in = conn.getInputStream();
BufferedImage image = ImageIO.read(in);
// you can get size dimesion
int width = image.getWidth();
int height = image.getHeight();
Whatever Chrylis says is right. You can do it only after downloading . First download your image file and save it to a specific path say it folder .
And from there, read it and get its height and width using below code:
BufferedImage readImage = null;
try {
readImage = ImageIO.read(new File(folder);
int h = readImage.getHeight();
int w = readImage.getWidth();
} catch (Exception e) {
readImage = null;
}
EDIT: To get ImageIO class in your android try the following:
go to project properties * java build pata->Add library *
and add JRE System Library and click finish . Now you can use java.awt package :)
