Question

我在将图像保存到Titanium中的本地应用程序文件时遇到问题。特别是从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'

这是我到目前为止的代码，我试图整理并测试我自己的搜索，他们不工作。异常被抛出

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

[错误]：TiFileProxy：at org.appcelerator.kroll.KrollRuntime $ KrollRuntimeThread.run（KrollRuntime.java:112）

我希望我能提供更多细节，但我很遗憾，道歉提前谢谢。

Titanium.Filesystem.resourcesDirectory是只读的。请查看所有位置的列表，包括http://docs.appcelerator.com/titanium/latest/#!/guide/Filesystem_Access_and_Storage-section-29004902_FilesystemAccessandStorage-Storagelocations
