In our application we are storing few pdf files inside asstes folder(<1MB).
Using Intent we want to open that pdf. Is it possible ? If yes, how to do
that ?
What we tried :
If we copy file from assets to sd card and then try to open using intent it
is working.
But we directly want to open it from assets folder.

It's hard to help if you don't provide enough information about your problem.

What are you using to "open" the PDF files? Do you mean "view/display"
or "read the file". Android does not support PDF natively so I suppose
that you use either an external application or a PDF rendering
library.

Doesn't <some-context-instance>.getAssets().open(assetName) work for you?

As you said, reading PDFs is not a native feature and requires an external
app, which would not have permission to read the PDF from another app's
Assets folder.
I believe the OP would have to write his own PDF viewer imbedded in his
app, or stick with the "copy to SDcard then open" strategy.

When user clicks on a button i want to open the pdf file stored inside our
application(ie which is inside Assets folder of our app). Open means , to
view the pdf file using Intent. I don't have any problem in using third
party applications to view pdf file.In the intent i sepcify mimetype , so
it will list all the pdf viewer installed in his phone. So user can select
his favorite pdf viewer to view the pdf file which is stored in our
application
<some-context-instance>.getAssets().open(assetName) will return
inputstream. That is not wht we need. Thanks for this suggestion
I guess now everything is clear. sorry for my bad English.

FYI apparently you don't need any permissions to access another app's
assets. I was surprised too, but see here:

I see. So I suggest you to create a content provider and invoke the
third-party app with a corresponding intent (supposing that the viewer
is able to read from a provider, of course). That would be the elegant
and fancy approach.
A not-so-fancy solution is to copy the PDF to the SD card and invoke
the viewer app with a file:// URI. This approach has a disadvantage:
it's hard to know when the copy can be removed because you don't know
when the viewer will stop accessing it.
