Android: What is the standard to load a file from the filesystem?

I am creating an Android app for the Samsung Galaxy Tab 10.1, bu开发者_运维问答t the user needs to be able to choose a file (like a text file) from the file system. In Windows, the easiest way to do this would be through an "Open File Dialog Box", but is there a standardized/built-in/simple way to do the same thing on an Android tablet?

Thanks a bunch!
