Ok... here's the client app side - I haven't tried running this as-is,
since it was culled from a much bigger piece of code. But this is the gist
of it:
package com.example;
public class ChromeAPIExample {
private static final String CHROME_APP_ID = "..."; // Replace with
actual Chrome app id
public ChromeAPIExample() {
initChromeListener();
}
private native void initChromeListener() /*-{
try {
$wnd.example = new Object();
$wnd.example.isChrome = function() {
var isChromeBrowser = false;
try {
isChromeBrowser = (typeof chrome !== 'undefined');
} catch (e) {
console.log('isChrome: cannot determine if using
chrome: ' + e);
}
return isChromeBrowser;
};
if (!$wnd.example.isChrome()) {
console.log('initChromeListener: not using chrome;
returning');
return;
}
if ($wnd.example.chromePort && ($wnd.example.chromePort !=
null)) {
console.log"initChromeListener: chromePort still exists,
returning");
return;
}
console.log('initChromeListener: this is chrome');
var thisInstance = this;
var chromeAppId = @com.example.ChromeAPIExample::CHROME_APP_ID;
try {
// Check if the app is installed and enabled by opening a
messaging port
var port = chrome.runtime.connect(chromeAppId);
if (port) {
$wnd.example.chromePort = port;
console.log('initChromeListener: got port: ' + port);
port.onMessage.addListener(function(msg) {
console.log('chrome listener: msg: ' + msg);
});
}
} catch (e) {
console.log('initChromeListener: Inner Error: ' + e);
}
} catch (e2) {
alert('initChromeListener: Outer Error: ' + e2);
}
}-*/;
}
... and here's a snippet of code from the Chrome app. If the above code
was run in GWT 2.6, the Chrome app would log the connection attempt from
the app. In GWT 2.8, we get a port object back from the Chrome connection
attempt, but the Chrome app doesn't see the connection attempt:
...
initialize();
function initialize() {
chrome.runtime.onConnectExternal.addListener(onConnectExternal);
}
function onConnectExternal(port) {
logMsg('onConnectExternal: port=' + port);
port.onDisconnect.addListener(function() {
logMsg('Port disconnected');
});
}
