Java JOGL Android应用程序可以'；无法写入外部存储器
我有一个Android应用程序，它使用JOGL进行OpenGL图形处理。该应用程序是GearsTestDemo，在其他地方用于测试。该应用程序在两个不同的平板电脑设备上运行和显示，一个运行4.4.2，另一个运行4.1.2。我正在尝试添加文件访问权限。我拥有清单文件中指定的写入和读取权限。我可以写入本地应用程序存储（在努力获得正确的上下文后）。当我尝试写入外部存储器时，打开失败：EACCES（权限被拒绝）。下面给出了logcat输出的一个片段，显示了错误。由于清单中的权限设置似乎是正确的，因此JOGL似乎以某种方式干扰了应用程序的写入能力。如有任何建议，将不胜感激 以下是清单文件：Java JOGL Android应用程序可以'；无法写入外部存储器,java,android,jogl,Java,Android,Jogl,我有一个Android应用程序，它使用JOGL进行OpenGL图形处理。该应用程序是GearsTestDemo，在其他地方用于测试。该应用程序在两个不同的平板电脑设备上运行和显示，一个运行4.4.2，另一个运行4.1.2。我正在尝试添加文件访问权限。我拥有清单文件中指定的写入和读取权限。我可以写入本地应用程序存储（在努力获得正确的上下文后）。当我尝试写入外部存储器时，打开失败：EACCES（权限被拒绝）。下面给出了logcat输出的一个片段，显示了错误。由于清单中的权限设置似乎是正确的，因此JO
