The most important class STSignoViewer can be used as a Fragment class in an Activity class. For further information, see also the STSignoViewerCreator.createSignoViewer() and STSignoViewerCreator.newInstance() methods. In this case, the android:configChanges attribute of the respective <activity> element should be edited in the Manifest file to specify that this Activity class carries out the following configuration changes.

<activity
    android:name="com.demo.app.DemoActivity"
    android:configChanges="orientation|keyboard|keyboardHidden|screenSize|screenLayout">
</activity>

The libSignoPdfSigner library can be integrated into your app as a new module with the Assistant in Android Studio, and specified as a dependency within the build.gradle file of your app:

dependencies {
    ...
    implementation project(‘:libSignoPdfSigner_x.x.x’)
}

The images required for the user interface exist in the library. To replace the existing images with your own images, you must create your own images in the respective ‘drawable’ folders in your app. The dimensions and file names of the custom images must correspond to those of the existing images.
