react-native-file-viewer | Native file viewer for React Native | iOS library

If your app is targeting Android 11 (API level 30) or newer, the following extra step is required, as described in Declaring package visibility needs and Package visibility in Android 11. If your app targets Android 11 or higher and needs to interact with apps other than the ones that are visible automatically, add the element in your app's manifest file. Within the element, specify the other apps by package name, by intent signature, or by provider authority, as described in the following sections. For example, if you know upfront that your app is supposed to open PDF files, the following lines should be added to your AndroidManifest.xml. IMPORTANT: Try to be as granular as possible when defining your own queries. This might affect your Play Store approval, as mentioned in Package visibility filtering on Android. If you publish your app on Google Play, your app's use of this permission is subject to approval based on an upcoming policy.
