I’m remote controlling a Java application on a PC through an Android phone, and I needed my application to open a browser at the phones command, chrome in this case. I created a “Process” for chrome, opening a certain address. However, I need to be able to give tools on the Android phone for controlling the web page, such as scrolling. Can I programmatically send a command for chrome to scroll from my PC application containing the Process?

Sorry, it may have been unclear, but the only connection the android phone has to the program is through a socket. It is only used as a remote control for another Java application on a PC, which has its own screen.

    I do not think that clean solution exists.

    But I can suggest the following directions:

    (1) try to investigate the native chrome API. If it has such ability call it with JNI.

    (2) Try to use class java.awt.Robot. It allows to simulate user’s activity, e.g. mouse clicks. Unfortunately it does not allow you to find any window outside your application, so it is a problem to decide where to perform the click.

    (3) You can create proxy server and make browser you open to go to the target URL through the proxy. The proxy server will insert into the page your javascript that will communicate with server. The application that opens browser will send commands to server. The javascript that you inserted will receive these commands using AJAX and perform them. JavaScript can scroll browser window, so theoretically you can implement this.
