HTML视频控件在Codenameone应用程序中无法正常工作

时间：2018-08-30 10:42:24

标签： codenameone

我有一个codenameone应用程序，该应用程序调用了用html5开发的安全网站。它使用html视频控件拍摄快照。该网站在chrome中完美运行。但是，当我从安装在Android设备上的codenameone应用程序调用它时，视频控件未显示在页面上。所需的相机权限在应用程序中设置。

答案 0 :(得分：0)

您需要在Android 6+中提示输入本机权限。将它们添加到XML仅适用于旧版本的Android。如果您使用代号为One的相机API，但这通常是自动的，但不适用于HTML，因为我们无法告知您将尝试访问相机。

您可以创建类似以下内容的native interface：

public boolean promptCameraPermission();

您可以在不需要其他所有平台的情况下将其保留为未实现状态，然后在支持为true时，只需调用它即可获得许可。

return checkForPermission(Manifest.permission.CAMERA, "This is required to take a picture");

请确保导入com.codename1.impl.android.AndroidImplementation;
