If you’re developing an application for mobile devices that has advanced features, you’ll most likely require approval from your user.
Applications shouldn’t be able to directly to access the camera or microphone, their location, etc. to safeguard the privacy of the user. It is essential to protect the user’s privacy by requesting permission to store and capture audio, photos, and video.
Let’s look at Facebook to find an example of camera access. You’re already familiar with these alerts, aren’t you?
To present your app in full, users need to grant permission. But what happens if a user is not willing to grant permission? You can guess that you aren’t able to provide this feature. So, you need permissions. There are different types like native access, android permissions, media permission settings in the react native community.
React Native is beneficial for web development as its a version of React JS.
What happens if we develop an application for editing photos? The solution is straightforward that we must obtain the permission of users to use their personal data.
How to Remove React-Native Permissions
When you create an application that needs access to information that could be sensitive stored on the device of a user, for example, their location, or their contacts it is necessary to seek permission from the user first. For example, to access the user’s media library, you will need to use MediaLibrary.requestPermissionsAsync().
When using Expo Go, there isn’t much to think about when dealing with permissions, other than requesting permissions prior to using specific APIs. This is different when you wish to publish your app on apps in a store. Be sure to take the permissions for iOS as well as the permissions of Android sections thoroughly before the app is released to stores. If you don’t set up or clearly explain the permissions, it could cause your app to be removed from the stores.

iOS permission – A managed workflow
To request permissions for permissions iOS it is necessary to specify the reasons why permissions are needed as well as install the app which can request permission. In the managed workflow you can achieve this by modifying to the ios.infoPlist property in the app.json file.
You can find the full list of available properties in Apple’s InfoPlistKeyReference. Apple also provides the fundamental guidelines for structuring this message within the Guidelines for Human Interface Guideline.

Android – Workflows that are managed
On native react Android permissions are a little more straightforward than iOS. The managed workflow allows permissions to be managed by using the android permissions property in your app.json file. In the default workflow, these permissions need to be set inside the file AndroidManifest.xml.
Certain Expo or React-Native permission modules include permissions in default. If you use expo-location, for example, both the ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION are implied and added to your app’s permissions automatically.
To limit the permissions that your managed workflow app needs make sure you change to the android permissions property in your app.json file to only list the permissions that you require as well as Expo will also list the minimum permissions required to run. Check out the permission kinds below for more information about the Android permissions are granted. There is a complete list of all permissions available within the Android Manifest permissions reference.
Read the android permissions documentation to find out which permissions are included in every version.
Applications that use dangerous or signature permissions that are not based on valid reasons might not be approved in the eyes of Google. Be sure to follow Android permissions guidelines and best guidelines when you are submitting your application.

As a default, the permissions implied by the module that you have installed are included in the AndroidManifest.xml at build time. To remove permissions, specify an android.
How to Remove Default React-Native Permission?
It happens sometimes that permissions are added to your Android APK. As explained in React Dev community.
- android.permission.INTERNET
- android.permission.SYSTEM_ALERT_WINDOW
- android.permission.READ_PHONE_STATE
- android.permission.WRITE_EXTERNAL_STORAGE
- android.permission.READ_EXTERNAL_STORAGE
We are going to start with READ_PHONE_STATE, WRITE_EXTERNAL_STORAGE, and READ_EXTERNAL_STORAGE Open your android/app/src/main/AndroidManifest.xml file.
In react community now add the three permission with tools:node=”remove” attribute, it is to make sure it gets deleted during the build. Note that the package identifier will be different, for below it is “com.myapp” because the project was created with npx react-native permission init myapp.
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.myappid"
+ xmlns:tools="http://schemas.android.com/tools">
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />
+ <uses-permission tools:node="remove" android:name="android.permission.READ_PHONE_STATE" />
+ <uses-permission tools:node="remove" android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
+ <uses-permission tools:node="remove" android:name="android.permission.READ_EXTERNAL_STORAGE" />
<application
android:name=".MainApplication"
android:label="@string/app_name"
android:icon="@mipmap/ic_launcher"
android:allowBackup="false"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
android:windowSoftInputMode="adjustResize">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name="com.facebook.react.devsupport.DevSettingsActivity" />
</application>
</manifest>Permissions Testing Manually
In most cases, you need to understand what happens when users refuse authorization, to make sure that it is performing the desired behavior. A restriction at the operating system level on each of the latest iOS version and latest Android version restricts apps from soliciting the same permission repeatedly (you can imagine how it can be a hassle for users to be repeatedly asked to grant permissions). In the event that you want to test various flows that require permissions during development, you might need to deinstall and then reinstall Expo Go. Expo Go app. In the simulator, it’s simple as simply deleting the application. Expo-CLI will install it when you next launch the project.
