【问题描述】：

我正在尝试在 android webview 中使用 Ar.js，在授予位置和相机权限后，我收到一个对话框，提示无法访问地理位置 [![like this][1]][1]。

当出现此对话框时，在日志中我收到一条错误消息ERROR(1): User denied Geolocation。这是完整的日志：

我已经在 android chrome 中检查了位置权限，并且位置权限在那里处于活动状态。

在这个弹出窗口之后，我得到另一个弹出窗口（即使我使用的是 Android） [![this][2]][2]

因此，我在放置 A-frame 的球体组件时遇到了麻烦，这也是 Ar.js 的起始问题。请帮帮我。

【问题讨论】：

设备方向确实需要不同的权限，我认为您应该尝试使用包含授权弹出框的最新A-Frame版本（1.0.4）。

@StéphaneAlbanese 进行回复，但即使使用 A-Frame 版本（1.0.4）和此处的链接aframe.io/docs/1.0.0/components/… 问题仍然存在，实际上添加device-orientation-permission-ui="enabled: true" 并没有做任何事情

【参考方案1】：

我正在回答我自己的问题，以便它可以帮助将来遇到同样问题的任何人。

罪魁祸首是在不同的地方两次使用 setWebChromeClient()，如下所示。

   webView.setWebChromeClient(new WebChromeClient() 
        public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) 
            callback.invoke(origin, true, false);
        
    );

    webView.setWebChromeClient(new WebChromeClient() 
        @Override
        public void onPermissionRequest(final PermissionRequest request) 
            final String[] requestedResources;
            if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) 
                requestedResources = request.getResources();
                for (String r : requestedResources) 
                    if (r.equals(PermissionRequest.RESOURCE_VIDEO_CAPTURE)) 
                        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) 
                            request.grant(new String[]PermissionRequest.RESOURCE_VIDEO_CAPTURE);
                        
                        break;
                    
                
            

        
    );

将其更改为单个 setWebChromeClient()（如下所示），第一个弹出窗口消失了。第二个弹出窗口现在只在安装应用程序时出现一次，到目前为止不会造成任何问题。（如果将来出现，我会更新答案）。

webView.setWebChromeClient(new WebChromeClient() 
            public void onGeolocationPermissionsShowPrompt(String origin, GeolocationPermissions.Callback callback) 
                callback.invoke(origin, true, false);
            

            @Override
            public void onPermissionRequest(final PermissionRequest request) 
                final String[] requestedResources;
                if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) 
                    requestedResources = request.getResources();
                    for (String r : requestedResources) 
                        if (r.equals(PermissionRequest.RESOURCE_VIDEO_CAPTURE)) 
                            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) 
                                request.grant(new String[]PermissionRequest.RESOURCE_VIDEO_CAPTURE);
                            
                            break;
                        
                    
                

            
        );
