How can I read and write files synchronously, using PhoneGaps Filesystem API? Is there a an synchronous wrapper available?

推荐答案

由于Android上的Java-工作，几乎不可能做同步实现的文件IO。这是因为Android中绑定到JavaScript环境的每个Java对象都运行在自己的线程上。

Because of the way the Java-to-JavaScript bridge on Android works, it is pretty much impossible to do a synchronous implementation of File IO. This is because each Java object in Android that is bound to the JavaScript environment runs on its own thread.

使用现有的 File API 在PhoneGap中可用 - 但异步使用。注册回调，通知您的应用程序IO处理完成。

Use the existing File API available in PhoneGap - but use it asynchronously. Register a callback with it that will notify your app that an IO process is complete.
