Titanium：从 Android 的 Camera/Gallery 图像本地保存文件

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。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'

这是我到目前为止的代码，我试图通过自己的搜索将它们放在一起并进行测试，他们不工作。抛出异常

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

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

我希望我能提供更多细节，但我迷路了，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
