CamScanner Android 13 SDK 33 Document Scanner | PDF Viewer | Admob | FB

Introduction

Welcome to the CamScanner Android 13 SDK 33 Tutorial! In this comprehensive guide, we will walk you through the process of integrating the CamScanner Android SDK into your Android app, allowing you to create a document scanner, PDF viewer, and monetize your app with AdMob and Facebook ads.

The CamScanner Android SDK provides a powerful and easy-to-use solution for scanning documents, converting them to PDFs, and sharing them with others. With this SDK, you can create a seamless document scanning experience for your users, making it easy for them to scan and share documents on-the-go.

In this tutorial, we will cover the following topics:

1. Setting up the CamScanner Android SDK
2. Implementing the document scanner functionality
3. Converting scanned documents to PDFs
4. Displaying PDFs in your app
5. Integrating AdMob and Facebook ads
6. Testing and debugging your app

Prerequisites

Before we begin, make sure you have the following:

• Android Studio installed on your computer
• A basic understanding of Java or Kotlin programming
• A physical Android device or an emulator for testing
• A CamScanner Android SDK license key (available on the CamScanner website)

Step 1: Setting up the CamScanner Android SDK

To start using the CamScanner Android SDK, you need to add the SDK to your Android project. Follow these steps:

1. Download the CamScanner Android SDK from the CamScanner website and extract the ZIP file to a directory on your computer.
2. Open your Android project in Android Studio and navigate to the app directory.
3. Create a new folder called libs and add the extracted SDK files to it.
4. In the build.gradle file, add the following lines of code:

   dependencies {
   implementation 'com.camscanner:camscanner-sdk:33.0.0'
   }

5. Sync your project with the Gradle files by clicking on the Sync Now button in the top-right corner of the Android Studio window.

Step 2: Implementing the document scanner functionality

To implement the document scanner functionality, you need to create a new activity in your app that will handle the scanning process. Follow these steps:

1. Create a new Java or Kotlin class that extends the Activity class. For example, you can name it DocumentScannerActivity.
2. In the DocumentScannerActivity class, import the necessary CamScanner SDK classes:

   import com.camscanner.camscannerSdk.CamScanner;
   import com.camscanner.camscannerSdk.CamScannerListener;

3. Create a CamScanner object and set up the scanning parameters:

   CamScanner camScanner = new CamScanner(this);
   camScanner.setScanMode(CamScanner.ScanMode.DOCUMENT);
   camScanner.setScanResolution(CamScanner.ScanResolution.HIGH);

4. Implement the onScanComplete method to handle the scanned document:

   camScanner.setOnScanComplete(new CamScannerListener() {
   @Override
   public void onScanComplete(Bitmap bitmap) {
       // Handle the scanned document here
   }
   });

5. Start the scanning process by calling the startScan method:

   camScanner.startScan();

   Step 3: Converting scanned documents to PDFs

To convert the scanned document to a PDF, you can use the CamScanner object's convertToPdf method. Follow these steps:

1. Get the scanned document bitmap from the onScanComplete method:

   Bitmap bitmap = camScanner.getScanBitmap();

2. Convert the bitmap to a PDF using the convertToPdf method:

   byte[] pdfBytes = camScanner.convertToPdf(bitmap);

3. Save the PDF bytes to a file or send them to a server for further processing.

Step 4: Displaying PDFs in your app

To display the PDFs in your app, you can use a PDF viewer library such as the Android PDF Viewer library. Follow these steps:

1. Add the Android PDF Viewer library to your project by adding the following line to your build.gradle file:

   dependencies {
   implementation 'com.github.barteksc:android-pdf-viewer:2.8.2'
   }

2. Create a new PDF viewer activity and import the necessary classes:

   import com.github.barteksc.pdfviewer.PDFView;
   import com.github.barteksc.pdfviewer.listener.OnPageChangeListener;

3. Set up the PDF viewer and load the PDF file:

   PDFView pdfView = findViewById(R.id.pdf_view);
   pdfView.fromBytes(pdfBytes)
      .load();

4. Implement the onPageChangeListener method to handle page changes:

   pdfView.setOnPageChangeListener(new OnPageChangeListener() {
   @Override
   public void onPageChanged(int page, int pageCount) {
       // Handle page changes here
   }
   });

   Step 5: Integrating AdMob and Facebook ads

To integrate AdMob and Facebook ads into your app, you need to follow these steps:

1. Create a new AdMob ad unit and add it to your app:

   AdView adView = findViewById(R.id.ad_view);
   AdRequest adRequest = new AdRequest.Builder().build();
   adView.loadAd(adRequest);

2. Create a new Facebook ad unit and add it to your app:

   FacebookAdView facebookAdView = findViewById(R.id.facebook_ad_view);
   FacebookAdRequest facebookAdRequest = new FacebookAdRequest.Builder().build();
   facebookAdView.loadAd(facebookAdRequest);

   Step 6: Testing and debugging your app

To test and debug your app, follow these steps:

1. Run your app on a physical Android device or an emulator.
2. Test the document scanner functionality by scanning a document and converting it to a PDF.
3. Test the PDF viewer functionality by loading a PDF file and navigating through its pages.
4. Test the AdMob and Facebook ads by loading them in your app and verifying that they are displayed correctly.

That's it! With these steps, you should now have a fully functional document scanner app with PDF viewer and AdMob and Facebook ads integration.
