java - 移动/复制捕获的图像phonegap android中的问题

Phonegap版本：3.3

安卓版本：4.0.4

我正在共享我提供的文件uri。

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

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

将捕获的图像移到SD卡时出现错误。我也尝试了window.resolveLocalFileSystemURL和window.resolveLocalFileSystemURI，但它们都不对我有用。

尝试将相机捕获的图像移动到SD卡后，出现错误代码“ 1”。

最佳答案

确保已在清单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，请在您的清单文件中添加以下代码。

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