We should change content of AndroidManifest.xml.

In my project .The path example/android/app/src/main/AndroidManifest.xml.

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

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

    <application
        android:name=".MainApplication"
        android:allowBackup="false"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme"
+       android:allowClearUserData="true"
+       android:usesCleartextTraffic="true">
        <activity
            android:name=".MainActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenSize"
            android:label="@string/app_name"
            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>
