Getting error while doing react-native link

1-Make sure you've done the npm install native-base --save in the project directory

2- Try npm i to fix the problems with dependencies, then commandreact-native run-android to make sure your dependencies and "node_modules" folder work properly and project can run.

If you don't have 'android' or 'ios' folder you can use command react-native eject, then link the packages.

3- Write the command react-native link native-base, this command links exactly native-base package with react native.
However I recommend you to mostly link the packages manually.

You can also try previous version of native base, like v 2.10.0.

Thank you @AmirGorji @parashKorat for helping me. For me, this problem was coming because I have removed android:roundIcon="@mipmap/ic_launcher_round" from the manifest file. When I put it again the react-native link is working. I removed it because after adding my icons it was showing the error of missing a round icon, for temporary I removed that.

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.namaztiming">

    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW"/>

    <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">
      <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>

I don't know is it a proper solution or not but in my case, it solved the problem.

I faced this issue today and what I did was ran these commands to clean the gradle for the project.

1- Go to the root directory of the project.

2- Run cd android

3- Run gradlew clean

4- Run cd..

and then run the link commands

Since react 0.69 linking is not working. The alternative is to install react-native-assets, but this gives me errors with react-native 0.69.4. So I decided to install manually.

For iOS:

Step 1 : Add/Remove fonts to “Resources” folder in xcode project

Note : Just Drag the fonts in xcode “Resources” folder and check “Copy items if needed” . Add to target should be your project.

if files are copied correctly you can see the files in “Copy bundle resources” in “Build phases” tab

Step 2 : Add/Remove fonts in info.plist files in xcode project with key “Fonts provided by application”

For Android:

Step 1 : Add/Remove fonts to android project in following directory

android/app/src/main/assets/
