Question

您好我在Gamemaker：Studio中制作了一个Android原生扩展程序，当我运行游戏并尝试使用扩展程序时，我在转轮命令窗口中收到此错误代码：

无法在扩展类上找到方法：folderLoader [double，double]

它不会使游戏崩溃或抛出任何其他错误，它只是在java文件中找不到我的方法。这就是我设置它的方式：

编辑扩展包属性 - 常规标签 -

name- DirectoryPicker

android复选框勾选

注入manifest-

<activity
android:name="${YYAndroidPackageName}.DirectoryPicker"
android:label="DirectoryPicker" />

注入gradle（激活我的styles.xml） -

compile 'com.android.support:appcompat-v7:+'

编辑扩展包属性-android选项卡 -

班级名称 - DirectoryPicker

权限 - android.permission.WRITE_EXTERNAL_STORAGE

编辑扩展文件属性框 -

name- DirectoryPicker.extension.gmx

init function-设置为folderLoader

copys仅限于安卓和Android yyc盒子

编辑扩展功能框 -

name- folderLoader

外部名称 - folderLoader

help- folderLoader（double FolderOnly，double ShowHidden）

返回类型框 - 选择双

键和值框 - 参数0 double argument1 double

对象的鼠标左键按下事件的调用代码：

folderLoader(1.0, 0.0);

同一对象中的异步事件（设置为社交事件）：

var type2 = string(async_load[? "type2"])
var data2 = string(async_load[? "folder"])
if type2 == "folderFound"
{ 
var text = data2;
}

java文件名为DirectoryPicker.java

    if(onlyDirs && !file.isDirectory())
        continue;
    if(!showHidden && file.isHidden())
        continue;
    files.add(file);
}
Collections.sort(files);
return files;
}

public String[] names(ArrayList<File> files) {
String[] names = new String[files.size()];
int i = 0;
for(File file: files) {
    names[i] = file.getName();
    i++;
}
return names;
}
}

我把两个相关的xml文件放在我放在res文件夹中的布局文件夹中，该文件夹位于AndroidSource文件夹中。我还下载了一些扩展，看看他们是如何做到的，并且他们都在android源文件夹中有一个名为yymanifest.xml的文件，由gamemaker生成，这个文件永远不会在我的扩展项目中创建，我试过保存，导出扩展并重新导入它，但文件永远不会存在，并且它不是你自己制作的文件，游戏制作者必须在制作扩展时生成它，但我怎么能让它做到这一点？

非常感谢任何想法或帮助

一切似乎都很好，你需要在menifest文件中提到你的文件夹。
