Titanium：从 Android 的相机/图库图像本地保存文件

Question

我在 Titanium 中将图像保存到本地应用程序文件时遇到问题。 专门从 event.media 创建文件；

function handleImageEvent(event) {
   imgpreview.image = event.media;

   var imaget = event.media;        
   var f = Titanium.Filesystem.getFile(Titanium.Filesystem.resourcesDirectory,imagename); 
   f.write(imaget);

}

//imagename :  I am using in the format of 'photo0.png'

这是迄今为止我尝试整理并通过自己的搜索进行测试的代码， 他们不工作。抛出异常

[WARN] :   TextView: TextView does not support text selection. Action mode cancelled.

我希望我能提供更多细节，但我很迷茫，抱歉 提前致谢。

Titanium.Filesystem.resourcesDirectory 是只读的。请在http://docs.appcelerator.com/titanium/latest/#!/guide/Filesystem_Access_and_Storage-section-29004902_FilesystemAccessandStorage-Storagelocations找到所有位置的列表，包括访问权限
