This tutorial only applies to Xamarin.Android.
DocumentActivity requires the full version of the PDFTron library. See PDFTron full or standard?

linkPrerequisites

  • Integrated PDFTron into your project and added the PDFTron.Android.Tools NuGet package into your project.
  • A valid evaluation or commercial license key. If you do not have a license key, please contact sales for a commercial license key or click here to get an evaluation key.
  • Minimum API: 16 (using Android Support Libraries)
  • Recommended target API: 28

linkStep 1: Update AndroidManifest.xml

  1. In order to support all the features in DocumentActivity, we will need to add the Android permissions listed in this table. However if you would like to disable certain features and customize your document viewer, you should leave out unnecessary permissions.
Storage permission
Please note that from Android 6.0 (API 23) and up, applications need to request storage permission at runtime before accessing any files on device.
  1. Enable largeHeap and usesClearTextTraffic:

    <application
        ...
        android:largeHeap="true"
        android:usesCleartextTraffic="true">
    </application>
If your app is targeting Android SDK version 28 or higher, you will need to add the android:usesCleartextTraffic="true" attribute in your application tag.
  1. If you have not done so already, add your license in the AndroidManifest.xml file, and also declare DocumentActivity in the manifest file. The final AndroidManifest.xml file should look something like this:

    <manifest ...>
        <!-- Required permissions are added here -->
        <uses-permission android:name="android.permission.INTERNET"/>
        <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
        <uses-permission android:name="android.permission.RECORD_AUDIO" />
        
        
        <!-- Add license key in meta-data tag here -->
        <meta-data
            android:name="pdftron_license_key"
            android:value="your_license_key_goes_here"/>
        
        <!-- Add enable largeHeap and usesCleartextTraffic -->
        <application 
            ...
            android:largeHeap="true"
            android:usesCleartextTraffic="true">    
                
            <!-- Document viewer activity declaration-->
            <activity android:name="com.pdftron.pdf.controls.DocumentActivity"
                android:configChanges="keyboardHidden|orientation|screenSize|screenLayout|smallestScreenSize"
                android:windowSoftInputMode="adjustPan"
                android:theme="@style/CustomAppTheme"/>
            ...
        </application>
    </manifest>

linkStep 2: Launch the viewer

Launch DocumentActivity by specifiying a local file path, an HTTP/HTTPS url, or a Content Uri:

// from internal storage
var localFile = Android.Net.Uri.FromFile(new Java.IO.File("myLocalFilePath"));
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, localFile);
// or if using config
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, localFile, config);
// or if using config and opening password protected file
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, localFile, password, config);

// from content uri
var contentUri = Android.Net.Uri.Parse("myContentUri");
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, contentUri);
// or if using config
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, contentUri, config);
// or if using config and opening password protected file
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, contentUri, password, config);

// from http/https
var fileLink = Android.Net.Uri.Parse("myFileLink");
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, fileLink);
// or if using config
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, fileLink, config);
// or if using config and opening password protected file
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, fileLink, password, config);

// from res
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, Resource.Raw.my_file_res_id);
// or if using config
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, Resource.Raw.my_file_res_id, config);
// or if using config and opening password protected file
pdftron.PDF.Controls.DocumentActivity.OpenDocument(this, Resource.Raw.my_file_res_id, password, config);
