java - 移动/复制捕获的图像phonegap android中的问题

Question

Phonegap 版本:3.3

安卓版本:4.0.4

我正在分享我得到的文件 uris 以供引用。

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 卡时遇到错误。我还尝试了 window.resolveLocalFileSystemURL 和 window.resolveLocalFileSystemURI 但它们都不起作用我。

当我尝试将相机拍摄的图像移动到 SD 卡时，出现错误代码“1”。

确保您已在 list 文件中添加了适当的权限以读取和写入外部存储。如果没有将以下代码添加到您的 list 文件中。

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