package com.example.bottomnavigationview;

import android.view.ViewGroup;

I think it needs to be put in some other way. Can somebody help? Because page in app don't downloading.***************************************************************************

follow this code snippet.
WebSettings webSettings = webView.getSettings();
webSettings.setJavaScriptEnabled(true);
webView.addJavascriptInterface(new WebAppInterface(), "Android");
webView.setWebViewClient(new WebViewClient());
webView.loadDataWithBaseURL(null, YOUR_URL, "text/html", "utf-8", null);
here, webView will be replaced with your view object.
Note: addJavascriptInterface is optional. It will be used in the case when you want a callback from webChromeClient. also, for more details about addJavascriptInterface, you can refer to https://stackoverflow.com/a/11572941/8237887

Progressbar is loading very fine at first time when main page loads. after that it disappear.

Use
progressBar.setVisibility(View.VISIBLE);
in onPageStarted method

progress bar in webview keeps loading even after web page finished loading

Here is my code

}
The progress bar and webview works fine but when the page is finished loading the progress bar still remains? When I have loaded the page the progress bar visibility doesn't dissapear/change to GONE? Where is the error?
Ive tried both progressBar.setVisibility(View.INVISIBLE) and progressBar.setVisibility(View.GONE); but nothin seems to work.

Instead of using customizing webclient. you use default webclient. your problem is replace this.
view.setWebViewClient(new WebViewClient());
add this
view.setWebViewClient(new MyAppWebViewClient());
and also
progressBar.setVisibility(View.INVISIBLE);
not
view.findViewById(R.id.progressBar1).setVisibility(View.GONE);

just changed WebViewClient to MyWebViewClient, progressBar to progressBar1 & ActionBarActivity to AppCompatActivity and every code seems to work :) thank again every1.. :) #Devendra & #akhil :)
my final code

progressBar = (ProgressBar) this.findViewById(R.id.progressBar1);
String url = "http://www.carsaleindiaofficial.com/?m=1";
view = (WebView) this.findViewById(R.id.webView);
view.setWebViewClient(new MyWebViewClient());
view.getSettings().setJavaScriptEnabled(true);
view.getSettings().setDomStorageEnabled(true);
view.loadUrl(url);
}
public class MyWebViewClient extends WebViewClient {
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
Log.i("pageFinished", "yesss");
progressBar.setVisibility(View.GONE);
Log.i("progressBar", "Gone");
}
#Override

Log.i("progressBar", "Visible");
super.onPageStarted(view, url, favicon);
}
#Override

view.loadUrl(url);
Log.i("ShldOvrideUrl", "working");
return true;
}
}
#Override

view.goBack();
} else {
super.onBackPressed();
}
}
#Override

return true;
}
#Override

int id = item.getItemId();
if (id == R.id.action_settings)
view.loadUrl(view.getUrl());
return super.onOptionsItemSelected(item);
}
}

After intent of webview url you have to write progressbar.visibility="View.GONE"

private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
progressBar.setVisibility(View.GONE);
FGallery.this.progressBar.setProgress(100);
super.onPageFinished(view, url);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progressBar.setVisibility(View.VISIBLE);
FGallery.this.progressBar.setProgress(0);
super.onPageStarted(view, url, favicon);
}
}
This is working for me. you can set it as WebViewClient.

When I made screen orientation change, my web view reach to home page automatically. I wanna make my web view activity to prevent restart activity when I made screen orientation change. Please, tell me how to do. Sorry for my poor English.

Use savedInstanceState. Load the url only when it is null.
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_webview);
wv = (WebView) findViewById(R.id.myWeb);

How to use go back in sites correct?

I have my WebViewFragment and of course i want to go back in the site im browsing but i have the error:
The method onBackPressed() is undefined for the type Fragment
Why? I don´t understand that?
What am i doing wrong?
Here´s my full webview code i´m using.
import android.app.Fragment;
import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import android.webkit.WebChromeClient;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class WebViewFragment extends Fragment {
WebView webView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Retrieving the currently selected item number
int position = getArguments().getInt("position");
String url = getArguments().getString("url");
// List of rivers
String[] menus = getResources().getStringArray(R.array.menus);
// Creating view corresponding to the fragment
View v = inflater.inflate(R.layout.fragment_layout, container, false);
// Updating the action bar title
getActivity().getActionBar().setTitle(menus[position]);
//Initializing and loading url in webview
webView = (WebView)v.findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadsImagesAutomatically(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.loadUrl(url);
webView.setWebChromeClient(new WebChromeClient());
webView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
view.loadUrl(url);
return true;
}
});
webView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
}
});
return v;
}
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}}
If i´m using:
public void onBackPressed() {
Fragment webview = getFragmentManager().findFragmentByTag("webview");
if (webview instanceof WebViewFragment) {
boolean goback = ((WebViewFragment)webview).canGoBack();
if (!goback)
super.onBackPressed();
}
}}
I have the errors:
The method canGoBack() is undefined for the type WebViewFragment
The method onBackPressed() is undefined for the type Fragment
Thank you dudes for your help!

Found the solution what is working for me in my fragment.
webView.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if (event.getAction() == KeyEvent.ACTION_DOWN) {
WebView webView = (WebView) v;
switch (keyCode) {
case KeyEvent.KEYCODE_BACK:
if (webView.canGoBack()) {
webView.goBack();
return true;
}
break;
}
}
return false;
}
});
return v;
