My Android app not supporting Android version 9

I have made an android app which uses webView. Everything was fine until I tried my app on Android P. On Android "P" the app is directly showing the error page that the app can't use Internet connection even though it is ON.

Android Manifest File:

    <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.xxx.xxxxx.xxxxx">
&lt;!-- android:roundIcon="@mipmap/ic_launcher_round" --&gt;

&lt;uses-permission android:name="android.permission.INTERNET" /&gt;
&lt;uses-permission android:name="android.permission.ACCESS_NOTIFICATION_POLICY"/&gt;
&lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
&lt;uses-permission android:name="android.permission.CAMERA" /&gt;

&lt;application
    android:allowBackup="true"
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    android:hardwareAccelerated="true"
    android:supportsRtl="true"
    android:theme="@style/AppTheme"&gt;
    &lt;activity android:name="com.xxxxx.xxxxx.xxxxxx.MainActivity"&gt;
        &lt;intent-filter&gt;
            &lt;action android:name="android.intent.action.MAIN" /&gt;

            &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
        &lt;/intent-filter&gt;
    &lt;/activity&gt;
&lt;/application&gt;

</manifest>

Gradle File:

    apply plugin: ‘com.android.application’

android {

compileSdkVersion 28

defaultConfig {

applicationId “com.xxx.xxx.xxx”

minSdkVersion 19

targetSdkVersion 28

versionCode 3

versionName “3.0”

testInstrumentationRunner “android.support.test.runner.AndroidJUnitRunner”

}

buildTypes {

release {

minifyEnabled false

proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’

}

}

}
dependencies {

implementation fileTree(dir: ‘libs’, include: [‘*.jar’])

implementation ‘com.android.support:appcompat-v7:28.0.0’

implementation ‘com.android.support.constraint:constraint-layout:1.1.3’

}

On Getting error in Android P, directly this section is being accessed:

public void onReceivedError(WebView view, int errorCode,

String description, String failingUrl) {

// You can redirect to your own page instead getting the default error page

            super.onReceivedError(view, errorCode, description, failingUrl);
            String path = Uri.parse("file:///android_asset/error.html").toString();
            webView.loadUrl("about:blank");
            view.loadUrl(path);
        }
