Hello everyone, in this video we will see how we can show a PDF file inside our Android app. When I click on the button here, a PDF file will open. Let's see how we can do that. To load the PDF, we will use a library called "Android PDF Viewer". I'll provide the link to this library in the description. Please copy the command and paste it inside our app-level Gradle file.

Now, when the user presses the button, we will load a new activity where we will show the PDF. Let's create a new activity by selecting "Empty Activity" and name it "PdfActivity". In the activity_pdf.xml file, change the root layout to RelativeLayout again. Inside, include com.github.something.pdfview, which represents the PDF view. Set the width and height of the PDF view as "match_parent" and assign it an "id" attribute called "pdfView". Now, let's update our PdfActivity.java file. In order to load the PDF, we will use a specific PDF file, a storybook PDF. Please copy the URL and paste it inside the "assets" folder of our project. To pass from the MainActivity to the PdfActivity when the button...
