[英]Phonegap Camera API - Cannot read property 'DATA_URL' of undefined
[英]Phonegap 3 (apache cordova) error with getpicture (Cannot read property 'PictureSourceType' and DATA_URL
我是使用Apache 3.3.0 cordova开发Web应用程序的新手。 尝试启动相机并使用插件文件传输需要花几天时间,但始终会给我同样的错误。
如果我将我的应用程序与phonegap 2.9一起使用,则一切运行正常,
我遵循的步骤使用3.3.0 cordova创建我的项目
我使用命令行创建了一个Hello应用,该应用安装了必要的插件,例如相机或文件传输。
我在config.xml的清单清单中添加了权限。
这不是问题。 非常感谢您的帮助。 我正在使用Eclipse并在Android 4.4.2上进行开发。

您无需手动编辑AndroidManifest.xml或config.xml即可安装插件。 在https://stackoverflow.com/a/20813323/529323上查看我的答案
我已经尝试过您的代码,并且“获取图片”功能有效。 只需以正确的方式安装插件即可。
尝试使用命令行安装所有必需的电话间隙插件
cordova plugin add org.apache.cordova.network-information
cordova plugin add org.apache.cordova.media
cordova plugin add org.apache.cordova.camera
它与我合作!
据我了解,问题出在CPU。 任何运行带有ARM CPU的4.4.2的设备都不会运行由Cordova开发的应用程序。 如果使用其他任何方法,则使用。 这就是为什么它对某些人有效,而对另一些人无效的原因。
