Android中的NoClassFoundError MultipartEntity错误

我无法解决此问题.我添加了以下罐子.

httpClient-4.2.5.jar
httpcore-4.2.4.jar
httpmime-4.2.5.jar

我通过“构建路径”中的“添加外部JAR”选项添加了这些jar,然后在eclipse项目的libs文件夹中手动添加了它们,但在调试以下行时却出现了以下错误.

MultipartEntity multipartEntity = new MultipartEntity(HttpMultipartMode.BROWSER_COMPATIBLE);

实际上,我正在尝试使用此将多个图像上传到我的php服务器.

解决方法:

发现自己.问题是我不包含READ_EXTERNAL_STORAGE权限.
我在清单中添加了以下行,并且行得通.

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