Re: [android-developers] Open PDF file from assets

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.

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.
