Certain features in PSPDFKit need additional permissions, which apps have to declare inside their manifest using
<uses-permission> elements. Some permissions are required by PSPDFKit and are defined in the
AndroidManifest.xml file that comes with the library. Other permissions are optional and can be added to the
AndroidManifest.xml file of your app if you want to make use of them.
ℹ️ Important: To protect user privacy, starting with Android 6.0 (API 23), users can revoke permissions of apps using the system settings. For dangerous permissions, apps have to perform additional runtime requests for specific permissions, which the user has to manually grant.

android.permission.CAMERA permission is optional and not part of PSPDFKit’s
AndroidManifest.xml. It is usually not required to add this permission to an app’s
PSPDFKit allows the creation of stamp annotations from gallery and camera images using the
AnnotationTool.CAMERA. For this, PSPDFKit will launch an
Intent using the
MediaStore.ACTION_IMAGE_CAPTURE action, which is used to return an image from either the camera app or a gallery app. As long as this permission is not declared in the app’s manifest, Android will allow the app to launch the intent without any additional permission requests. However, as soon as the app declares
android.permission.CAMERA in the manifest, Android will require the app to perform a runtime request for this permission on all devices running Android 6.0+. PSPDFKit will automatically detect if the permission is declared and a runtime permission request is necessary, and it will request access to the camera upon using the camera tool for adding an annotation.
External Storage Permission
AndroidManifest.xml comes with two permission declarations for accessing files on the public external storage. These permissions are:
External storage permissions are required for direct file access when using filesystem
Uris that point to files on the external storage. Upon opening a document using a
Uri, PSPDFKit will automatically check if the file resides on the external storage, and it will perform a runtime permission request if necessary.
