i tried to build a web view app from scratch and as i am new to this i was facing error on line 22, as i set websetting.setjavascriptenabled(true); it didnt accept.

error popup

error: non-static method setJavaScriptEnabled(boolean) cannot be referenced from a static context
 WebSettings.setJavaScriptEnabled(true);

my project settings is for android Oreo 8.1

package net.jptechsolutions.jptechinvoice;

import android.annotation.SuppressLint;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebChromeClient;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

public WebView mywebview;

@Override
protected void onCreate(Bundle savedInstanceState) 
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);
 mywebview=(WebView)findViewById(R.id.webview);

 WebSettings webSettings=mywebview.getSettings();
 WebSettings.setJavaScriptEnabled(true);

 mywebview.loadUrl("https://*********************");

 mywebview.setWebChromeClient(new WebChromeClient());




@Override
public void onBackPressed() 
 if (mywebview.canGoBack())
 
 mywebview.goBack();
 
 else
 
 super.onBackPressed();
 

Use

webSettings.setJavaScriptEnabled(true); 

instead of

 WebSettings.setJavaScriptEnabled(true);

You are using Class name with method name. Use the object name defined by you with the method name.

You call the static function of WebSettings. It should be: webSettings. setJavaScriptEnabled(true);
