Link to the app on google drive我在gitHub上安装了此应用，但与此应用不完全相同，这就是为什么我将此版本上传到google驱动器而不是gitHub
screenshot屏幕截图还包含问题的摘要
这里的新手，这可能是一个简单的修复程序，但我只是没有找到它。
我在屏幕底部有一个带有家具图片/图标的菜单。我希望当您单击其中一张图片并单击锚点（我可以在其中放置对象/资产的地方）时，应将对象放置在您点击的锚点上
我尝试在点击锚点后登录到调试控制台，只是为了查看应用程序是否识别出被窃听了什么资产/对象。
例如，如果我轻按椅子，然后轻按锚点，则应用程序确实设法识别出我轻按了椅子。
我已经安装了sceneform插件 我的gradle依赖项中有sceneform
对不起，所有这些代码，只是不知道问题出在哪里。
我的猜测是它只会在放置对象时出现，我想为可能需要查看缺失部分的任何人添加它

我希望当我单击家具的图片然后单击锚点时，该对象将显示在锚点上。取而代之的是，当我这样做时，该应用程序会出现“故障”，然后我的水龙头没有得到任何回应
答案 0 :(得分：0)
因此，在不同的设备上进行了一些测试之后，我设法在其中一个设备上收到一条错误消息，指出没有“此类文件”。因此，我认为它必须是定义到文件的路径。修复后，我设法使其正常工作
