Targetting to multiple file format file (eg. pdf, doc, ppt)

In Iphone you can open pdf and other file format using WebView. so, why android is not having similar functionality, for online mode we can use "http://docs.google.com/gview?embedded=true&url= "

but in offline mode(without the internet access) how u'r go开发者_C百科ing to do. -- so, any how you are going to manage for pdf. file also then how you are going to target for other file format. It's really a biggest issue... I am struck with these things and aspect better solution. Thank you.

There are no JAR's that I'm aware of at the moment, but there is a project here that allows you to view PDF's, maybe you wanna give that a try?!

In Android the only way is using Intent and set the setContentType for the particular file format which will redirect to the number of application support the file format.
