Question

After certain research and lookup over the internet I found that I cannot place these files in the assets folders as those files will be private to my application, I want the native pdf application to be invoked on a button press which redirects the user to the particular document. What I am confused about is how do I bundle the files with my application so that when the user downloads or installs my application these files get stored in her SD-Card.

Answer 1

copy your assests files to the sdcard and when clicking on the button open the files in the sdcard as like this

 File rootDir = Environment.getExternalStorageDirectory();

 File file = new File(rootDir + "/filepath/"+fileName);//give the file path here
 if(file.exists())
   {
    // do action here
   }
