Ok so I've been working on an app in Android Studio for school. I have a webview inside of a fragment. But in the app, when ever I open the fragment on my phone, the app crashes and my phone says "Unfortunately, LARKer App has stopped."
Here's the Fragment class:
import android.content.Intent;
import android.net.Uri;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/**
* Created by Andrew on 12/29/2014.
*/
public class menu4_Fragment extends Fragment {
private WebView mWebView;
View rootview;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
rootview = inflater.inflate(R.layout.menu4_layout,container,false);
mWebView = (WebView) getView().findViewById(R.id.webView);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("foo");
mWebView.setWebViewClient(new MyWebViewClient());
return rootview;
}
public class MyWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if(Uri.parse(url).getHost().contentEquals("foo")) {
// This is my website, so do not override; ler my WebView load the page
return false;
}
//Otherwise, the link is not for a page on my site, so launch another Activity that handles URLs
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
startActivity(intent);
return true;
}
}
}
And here's the XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="LARK: Login"
android:id="@+id/textView"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="35dp"
android:textSize="50dp" />
<WebView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="@+id/webView"
android:layout_below="@+id/textView"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true" />
</RelativeLayout>
Here's an image of what I got on my phone:

Try this code,
WebView webViewInfo = (WebView) findViewById(R.id.webview);
webViewInfo.getSettings().setJavaScriptEnabled(true);
webViewInfo.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
webViewInfo.setWebViewClient(new MYWEBCLIENT());
webViewInfo.loadData("LOAD_YOUR_URL", "text/html", "UTF-8");
And WebViewClient class implement on webview method.
private class MYWEBCLIENT extends WebViewClient {
@Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
On keyboard back handle,
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && webViewInfo.canGoBack()) {
webViewInfo.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
I hope this code help for you...!!

Change this code
mWebView = (WebView) getView().findViewById(R.id.webView);
Like this, it will work
mWebView = (WebView) rootview.findViewById(R.id.webView);
You have to get the view's from your View Group.otherwise it will return error.
