移动/复制拍摄的图像phonegap android的问题

Question

Phonegap版本：3.3

安卓版本：4.0.4

我正在分享我得到的文件uri以供参考

FILE_URI=content://media/external/images/media/11679

FILE_URI=file:///mnt/sdcard/Android/data/com.allplugins/cache/1393913804418.jpg

我在将捕获的图像移动到SD卡时出错。我也尝试过window.resolveLocalFileSystemURL和window.resolveLocalFileSystemURI，但都不适用。

当我试图将相机拍摄的图像移动到sd卡时，我得到了错误代码"1"。

Answer 1

确保在清单文件中添加了读取和写入外部存储的适当权限。如果没有，请将以下代码添加到您的清单文件中。

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

问题在于phonegap 3.3。我已经用phonegap 3.4测试了我的代码，它的工作原理很有魅力。
