This directory contains an example of chrome application that uses native messaging API that allows to communicate with a native application.
In order for this example to work you must first install the native messaging host from the host directory.
To install the host:
On Windows: Run install_host.bat script in the host directory. This script installs the native messaging host for the current user, by creating a registry key HKEY_CURRENT_USER\SOFTWARE\Google\Chrome\NativeMessagingHosts\com.google.chrome.example.echo and setting its default value to the full path to host\com.google.chrome.example.echo-win.json . If you want to install the native messaging host for all users, change HKCU to HKLM. Note that you need to have python installed.
On Mac and Linux: Run install_host.sh script in the host directory: host/install_host.sh By default the host is installed only for the user who runs the script, but if you run it with admin privileges (i.e. 'sudo host/install_host.sh'), then the host will be installed for all users. You can later use host/uninstall_host.sh to uninstall the host.
