Question

我正在尝试使用Cordova为Android构建一个hello world插件。项目运行没有错误但我无法得到结果。我的logcat返回错误Error adding plugin。这是我的代码

javacript

window.func = function(str,callback){
            alert("Outside Call Working");
            cordova.exec(callback, function(err){alert(err)},"HelloPlugin","echo", [str]);
        }
        function callPlugin(str){
            alert("JS Working");
            window.func(str,function(){
                alert("Done!");
            });
        }

的Android

public class HelloPlugin extends CordovaPlugin{

     @Override
        public boolean execute(String action, JSONArray args, CallbackContext callbackContext) throws JSONException {
            if(action.equals("echo")){
                String message = args.getString(0); 
                callbackContext.success(message);
                return true;
            }
            callbackContext.success(action);
            return true;
        }     
}

config.xml中

<feature name="HelloPlugin">
        <param name="android-package" value="com.ionicframework.myapp554544" />
    </feature>

注意：

上述代码从（Creating a helloWorld plugin for Android using Cordova and Eclipse）此问题中被盗

Answer 1

cordova.exec(callback, function(err){alert(err)},"HelloPlugin","echo", [str]);

应更改为：

cordova.exec(callback, function(err){alert(err)},"org.apache.cordova.plugin.HelloPlugin","echo", [str]);

将您的xml条目更改为：

<plugin name="HelloPlugin" value="com.example.plugintest.HelloPlugin" />

使用cordova的android世界插件
