1. Can I add the contents by typing something in the document and save it as PDF using iText library? As like we are creating word documents...?
2. Suppose if I want to insert an image in my document, it will be done by picking an image from my External storage using a dialog box...?

These are multiple questions. I'll try answering them all. However it seems one answer to all your questions is, first try, study, learn what iText is about, then ask questions

but my question is can i able to add the contents by typing something in the document and save it as PDF using iText library? like we are creating word documents...?

No, you have to do it programmatic. iText is not a WYSIWYG tool like Adobe Acrobat or other GUI-PDF Editors.

suppose if i want to insert a image in my document, it will be done by picking an image from my External storage using a dialog box...

If you create the dialog box and the code logic to add it to a PDF in the iText way it is possible.

is it possible using iText library in android...?

The general available iText is not fit for Android. You can contact iText Sales department to know more about iText Android.
