I am using iTextG for an android application. My objective is to read from an existing pdf file for later manipulations etc. I want to read a file called "Chemistry.pdf" which I have placed in my assets folder. I am using the following code to (try to) read the pdf
AssetManager assetManager = getAssets();
InputStream istr = null;
try
{
istr =(InputStream) assetManager.open("Chemistry.pdf");
Log.d("OK", "done");
}
catch (FileNotFoundException e)
{
// TODO Auto-generated catch block
e.printStackTrace();
}
catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
when I execute the code, the app crashes. if assets doesnt work, where should I include the pdf file(inside the app) ? What is going wrong ?
P.S. I get these error (there are 11 more)
