Apps using PSPDFKit need to initialize the framework before its first use. This can be done either automatically at application startup, or manually. Before initializing PSPDFKit, be sure to acquire a valid license key.
The easiest way to initialize PSPDFKit is automatically during application startup. To use automatic initialization, add a
<meta-data> element to your app’s
AndroidManifest.xml. When present, PSPDFKit will initialize itself as soon as your app starts:
1 2 3 4 5
<application> <meta-data android:name="pspdfkit_license_key" android:value="YOUR_LICENSE_KEY_GOES_HERE" /> </application>
In some situations, you might want to initialize PSPDFKit manually at a later point (i.e. not during app startup). This can be done by omitting the
<meta-data> element in your
AndroidManifest.xml. When doing so, PSPDFKit won’t initialize itself at startup. Instead, use the
PSPDFKit.initialize() method, providing your personal license key:
Since initialization can take some time (due to extraction and loading of PSPDFKit’s native libraries), make sure to initialize PSPDFKit on a background thread, in order to not block your UI.
