In JavaIn Java
public class CirclesActivity extends DroidGap {
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
super.loadUrl("file:///android_asset/www/index.html"); }}
Native Wrapper with PhoneGap
public class callsPGPlugin extends Plugin { // List Actions
public static final String ACTION="list";@Overridepublic PluginResult execute(String action, JSONArray data,
String callbackId) {
PluginResult result=null;
if(ACTION.equals(action)){CallLogAI callLogAI = new CallLogAI(ctx);JSONObject
callsHistory=callLogAI.fetchCallLogs(null);Log.d("RESULT=", callsHistory.toString());result=new
PluginResult(Status.OK,callsHistory);}else{
result=new PluginResult(Status.INVALID_ACTION);
Log.d("CallsPlugin","Invalidate action:" + action);
}return result;
}}
Java 定制 plugin
注册 plugin
<?xml version="1.0" encoding="UTF-8"?><plugins> <plugin name="App" value="com.phonegap.App"/> <plugin name="Geolocation" value="com.phonegap.GeoBroker"/> <plugin name="Device" value="com.phonegap.Device"/> …… <plugin name="Temperature" value="com.phonegap.TempListener"/> <plugin name="FileTransfer" value="com.phonegap.FileTransfer"/> <plugin name="Capture" value="com.phonegap.Capture"/>
<plugin name="CallsHistoryPlugin" value="com.mark.phonegap.plugin.callsPGPlugin" />
</plugins>
In JavaScriptIn JavaScript
Javascript 接口var CallsListing=function(){};
CallsListing.prototype.list=function(successCallback,failureCallback){
return PhoneGap.exec(successCallback, failureCallback, 'CallsHistoryPlugin', 'list',['test']
);};
PhoneGap.addConstructor(function(){PhoneGap.addPlugin("callsListing",new CallsListing);
});
window.plugins.callsListing.list(function(r){printResult(r)},function(e){console.log(e)}
);
Javascript 调用 plugin
小结小结
window.plugins.callsListing.list(function(r){printResult(r)},function(e){console.log(e)}
);
CallsListing.prototype.list=function(successCallback,failureCallback){
return PhoneGap.exec(successCallback,
failureCallback,'CallsHistoryPlugin','list',['test’]);
}; public class callsPGPlugin extends Plugin {
// List Actionspublic static final
String ACTION="list";@Overridepublic PluginResult
execute(String action, JSONArray data, String callbackId) {
<plugin name="CallsHistoryPlugin" value="com.mark.phonegap.plugin.callsPGPlugin" />

From JS to Native
From Native to JS
CallsListing.prototype.list=function(successCallback,failureCallback){
return PhoneGap.exec(successCallback,failureCallback,'CallsHistoryPlugin','list',['test’]);
};
PhoneGap.exec = function(success, fail, service, action, args) {… var r = prompt(JSON.stringify(args), "gap:"+JSON.stringify([service, action, callbackId, true]));…
Droidgap.java
public boolean onJsPrompt(WebView view, String url, String message, String defaultValue, JsPromptResult result) {……
String r = pluginManager.exec(service, action, callbackId, message, async);
…… }
Pluginmanager.java
public String exec(final String service, final String action, final String callbackId, final String jsonArgs, final boolean async) {
……cr = plugin.execute(action, args, callbackId);ctx.sendJavascript(cr.toErrorCallbackString(callbackId));
……}
Pluginmanager.java
ctx.sendJavascript(cr.toErrorCallbackString(callbackId));
CallbackServer.java ： XHR server
PhoneGap.Channel.join(function() {
// Start listening for XHR callbacks setTimeout(function() { if (PhoneGap.UsePolling) { PhoneGap.JSCallbackPolling(); }…

JS 到 Native 的通讯
document.location = “gap://Class.method/args”
Native 到 JS 的通讯
UIWebView.stringByEvaluatingJavaScriptFromString
webView =[[UIWebView alloc] initWithFrame:webViewBounds];
