java - Android request a url with out opening browser

Question

So I have an arduino with an Ethernet shield and I am currently controlling it using browser url commands eg "192.168.2.1/digital/2/1" (digital pin 2 goes high), i want to have an android button which requests that url without opening it in the browser.. is that possible and how would i do it?

Answer 1

这就是我在 Android 中执行 URL 请求的方式：

public InputStream download(String url) {
    URL myFileURL = null;
    InputStream is = null;
    try {
        myFileURL = new URL(url);
        is = myFileURL.openStream();
    } catch (Exception e) {
        System.out.println(e.getMessage());
    }
    return is;
}

这将返回该 URL 中的任何内容，并且永远不会打开浏览器。您可以选择任何您想要对 InputStream 执行的操作。
