我正在尝试使用 Cordova 为 Android 构建一个 hello world 插件。该项目运行没有错误，但我无法得到结果。我的 logcat 返回错误添加插件时出错。这是我的代码
java脚本
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!");
});
}
安卓
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;
}
}
配置.xml
<feature name="HelloPlugin">
<param name="android-package" value="com.ionicframework.myapp554544" />
</feature>
注意:
上述代码是从(Creating a helloWorld plugin for Android using Cordova and Eclipse)这个问题中窃取的

最佳答案
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]);
还将您的 xml 条目更改为:
<plugin name="HelloPlugin" value="com.example.plugintest.HelloPlugin" />
