 NOTE: When integrating with [React Navigation deep linking](https://reactnavigation.org/docs/deep-linking/#set-up-with-bare-react-native-projects), be sure to make this scheme (and the scheme in the config's redirectUrl) unique from the scheme defined in the deep linking intent-filter. E.g. if the scheme in your intent-filter is set to `com.myapp`, then update the above scheme/redirectUrl to be `com.myapp.auth` [as seen here](https://github.com/FormidableLabs/react-native-app-auth/issues/494#issuecomment-797394994).
 
-#### Allow permission to access the network state
-You need to add the `ACCESS_NETWORK_STATE` permission to your `AndroidManifest.xml` file. Here's how you can do it:
-
-1. Open your `AndroidManifest.xml` file located in the `android/app/src/main` directory of your React Native project. 
-2. Add the following line inside the `<manifest>` element, just before the `<application>` element:
-
-```xml
-<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
-```
-Your manifest should look something like this:
-
-```xml
-<manifest xmlns:android="http://schemas.android.com/apk/res/android"
-    package="com.yourpackagename">
-
-    <uses-permission android:name="android.permission.INTERNET"/>
-    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
-
-    <application
-        android:name=".MainApplication"
-        android:label="@string/app_name"
-        android:icon="@mipmap/ic_launcher"
-        android:roundIcon="@mipmap/ic_launcher_round"
-        android:allowBackup="false"
-        android:theme="@style/AppTheme">
