从android_asset文件夹复制到SD卡复制文件 [英] Copying files from android_asset folder to SD Card

问题描述

所以，我要玩那些在科尔多瓦的应用程序捆绑的视频文件。要做到这一点，我要他们搬出 android_asset 文件夹和到SD卡上。我想，如果在所有可能通过文件API为此在JS，

So, I want to play video files that are bundled in a Cordova app. To do that, I have to move them out of the android_asset folder and onto the SD card. I'd like to do this in JS via the File API, if at all possible.

话虽这么说，我似乎无法从我的科尔多瓦的WebView该文件夹阅读。

That being said, I seem to be unable to read from that folder with my Cordova WebView.

我已经尝试了几种不同的方法，但这里有两个，基于我读过，的应的工作：

I've tried a few different methods, but here are the two that, based on what I've read, should work:

var url = 'file:///android_asset/www/my_video_folder';
var sourceDir = new DirectoryEntry( { fullPath: url } );
var reader = sourceDir.createReader();
reader.readEntries( success, error );

和

window.resolveLocalFileSystemURI(url, success, error);

在这两种情况下，错误回调被调用，以错误。code == 5 （ FileError.ENCODING_ERR ）。

In both cases, the error callback is called, with error.code == 5 (FileError.ENCODING_ERR).

是我在做什么刚才的无法的？难道我的文件在Java code复制？

Is what I'm doing just not possible? Do I have to copy the files in the Java code?
