public class Echo extends CordovaPlugin {
@Override
public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
if (action.equals(echo)) {
String message = args.getString(0);
this.echo(message, callbackContext);
return true;
}
return false;
}
private void echo(String message, CallbackContext callbackContext) {
if (message != null && message.length() > 0) {
callbackContext.success(33333333333333);
} else {
callbackContext.error(Expected one non-empty string argument.);
}
}
}
2.2 配置plugin：
在res/xml/中有個confi.xml配置文件，在這個配置文件中增加plugin
Hello Cordova
A sample Apache Cordova application that responds to the deviceready event.
HelloWorld
Hello World sample application that responds to the deviceready event.
PhoneGap Team
2.3編寫js代碼（橋梁）
在assert/www/js/ 目錄中創建echo.js 內容如下：
var echoPlugin =
{ createEvent: function(title, location, notes, startDate, endDate, successCallback, errorCallback)
{
cordova.exec(
successCallback, // success callback function
errorCallback, // error callback function
'Echo', // mapped to our native Java class called CalendarPlugin
'echo', // with this action name
[{ // and this array of custom arguments to create our entry
title: title,
description: notes,
eventLocation: location,
startTimeMillis: startDate.getTime(),
endTimeMillis: endDate.getTime()
}]
);
}
}
2.4 在index.js裡面增加與Java的通訊代碼如下：
