Itextg Causing Application Crash(android)

My objective is to superimpose contents of a pdf onto another PDF. this is the code that I have used: AssetManager assetManager = getAssets(); InputStream istr = null; Pdf

Solution 1:

I assume the exception occurs here:

istr =(InputStream) assetManager.open("Chemistry.pdf");

The exception

java.lang.ClassCastException: android.content.res.AssetManager$AssetInputStream cannot be cast to com.itextpdf.text.pdf.codec.Base64$InputStream

indicates that the InputStream in that code line is not the expected java.io variant.

Most likely you have an import like

import com.itextpdf.text.pdf.codec.Base64.InputStream

while you actually wanted

import java.io.InputStream
