I'm new to app dev and have searched for a solution to this problem to no avail. I'm creating an app for that incorporates webview and I'm trying to remove the action bar I've tried using actionBar.hide(); and actionBar.setDisplayShowTitleEnabled(false);. I even tried actionBar.setHideOnContentScrollEnabled(true);. What it does is open the app window, then the screen goes black, the app closes and [Unfortunately, app has stopped] pops up.

here's my code
`

import android.app.ActionBar;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.KeyEvent;

import android.view.View;

import android.webkit.WebChromeClient;

import android.webkit.WebSettings;

import android.webkit.WebView;

import android.webkit.WebViewClient;

import android.widget.ProgressBar;



public class MainActivity extends AppCompatActivity {





    WebView webA;

    ProgressBar progressBar;



    private WebView myWebView;



    @Override

    public void onBackPressed() {

        if (webA.canGoBack()) {

            webA.goBack();

        }

    else {

        finish();

    }

}



@Override

protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);



    ActionBar actionBar = getActionBar();

    actionBar.setDisplayShowTitleEnabled(false);//hide title





    webA = (WebView)findViewById(R.id.webA);

    webA.setWebViewClient(new WebViewClient()); // This ensures that it's opened in the webView not default browser

    webA.loadUrl("https://www.fiander.me");



    // Progress bar

    progressBar = findViewById(R.id.progressBar);

    progressBar.setMax(100);

    // WebView

    WebSettings webSettings = webA.getSettings();

    webSettings.setJavaScriptEnabled(true);

    webA.setWebChromeClient(new WebChromeClient(){

`

In your manifest AndroidManifest.xml you define your app's theme, something like:

android:theme="@style/AppTheme"

and this theme is defined in styles.xml, something like:

<style name="AppTheme" parent="Theme.AppCompat.Light.LightActionBar">

change it to:

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

so there is no ActionBar in your app

and you can remove this code:

ActionBar actionBar = getActionBar();

actionBar.setDisplayShowTitleEnabled(false);//hide title

from onCreate()

I found a way to fix it. What I did was:

In the projects tab I went into -- res > values > styles.xml.

then changed the parent name to Theme.AppCompat.Light.NoActionBar
like so:

<!-- Base application theme. -->

<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">

    <!-- Customize your theme here. -->

    <item name="colorPrimary">@color/colorPrimary</item>

    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
