Add this line - android:usesCleartextTraffic="true" under the application tag of your manifest file.

I have updated the code of your manifest file with the required statement.

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

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

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:usesCleartextTraffic="true"
        android:theme="@style/AppTheme">
        <activity android:name=".scandemo"></activity>
        <activity android:name=".Scanner" />
        <activity android:name=".ProductTable" />
        <activity android:name=".ProductView" />
        <activity android:name=".addproduct" />
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity android:name=".ActivityOne" />
    </application>

</manifest>
