Android How to make full screen Video?

When I make a video full screen in WebView, the toolbar is not hidden. How can I hide it? Below you can see the codes I use.I'm using fragment and the navigation drawer menu.

I would recommend you to try out the follow code and remove the listeners which are related to loading the contents of your WebView.
You need to implement the method to load the website in your webview first.
private void loadWebsite() {
ConnectivityManager connectivityManager = (ConnectivityManager) getApplication().getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager .getActiveNetworkInfo();
if (networkInfo != null && networkInfo.isConnectedOrConnecting()) {
mWebView.loadUrl("yourURL");
} else {
mWebView.setVisibility(View.GONE);
}
}
From here, you need to implement 2 different class "Browser_Home" and "MyChrome". For testing purposes, just write it outside searchWebFragment and later on you can implement it as a separate java file. With only the Browser_Home class, the fullscreen button will be disabled. When MyChrome class is added, fullscreen button is enabled and toolbar should disappear as intended.
class Browser_home extends WebViewClient {
Browser_home() {
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
setTitle(view.getTitle());
progressBar.setVisibility(View.GONE);
super.onPageFinished(view, url);
}
}
private class MyChrome extends WebChromeClient {
private View mCustomView;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
protected FrameLayout mFullscreenContainer;
private int mOriginalOrientation;
private int mOriginalSystemUiVisibility;
MyChrome() {}
public Bitmap getDefaultVideoPoster()
{
if (mCustomView == null) {
return null;
}
return BitmapFactory.decodeResource(getApplicationContext().getResources(), 2130837573);
}
public void onHideCustomView()
{
((FrameLayout)getWindow().getDecorView()).removeView(this.mCustomView);
this.mCustomView = null;
getWindow().getDecorView().setSystemUiVisibility(this.mOriginalSystemUiVisibility);
setRequestedOrientation(this.mOriginalOrientation);
this.mCustomViewCallback.onCustomViewHidden();
this.mCustomViewCallback = null;
}
public void onShowCustomView(View paramView, WebChromeClient.CustomViewCallback paramCustomViewCallback)
{
if (this.mCustomView != null)
{
onHideCustomView();
return;
}
this.mCustomView = paramView;
this.mOriginalSystemUiVisibility = getWindow().getDecorView().getSystemUiVisibility();
this.mOriginalOrientation = getRequestedOrientation();
this.mCustomViewCallback = paramCustomViewCallback;
((FrameLayout)getWindow().getDecorView()).addView(this.mCustomView, new FrameLayout.LayoutParams(-1, -1));
getWindow().getDecorView().setSystemUiVisibility(3846);
}
}
And finally, apply the following functions and attributes to your webview and give it another try. Remember to apply these within your OnCreate method:
mWebView.setWebViewClient(new Browser_home());
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
webSettings.setAllowFileAccess(true);
webSettings.setAppCacheEnabled(true);
loadWebsite();
Let me know if this works and I can credit the corresponding person for the assistance with the code and classes.

create a folder row and copy the video on raw folder on resources and do the following steps,
On your XML file add VideoView,
<VideoView
android:id="#+id/vdoPlayer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"/>
On your .java class file do,
Uri uri = Uri.parse("android.resource://Your package name Here/" + R.raw.welcome_video);
vdoPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.setLooping(true);
}
});
vdoPlayer.setVideoURI(uri);
vdoPlayer.start();

How can i block or avoid popup in webview?

the webpage have some popup ads is there any way to prevent the popup from loading when the popup loads the main site doesnt appears is there any way to load the main page with out popups and how can i add a download handler l mean the webview should support downloading .torrent file
public class MainActivity extends AppCompatActivity {
private WebView webView;
private ProgressBar progressBar;
private LinearLayout layoutProgress;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = (WebView) findViewById(R.id.webView);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
layoutProgress = (LinearLayout) findViewById(R.id.layoutProgress);
webView.setVisibility(View.GONE);
WebSettings settings = webView.getSettings();
settings.setJavaScriptEnabled(true);
settings.setBuiltInZoomControls(true);
settings.setSupportZoom(true);
settings.setDisplayZoomControls(false);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
webView.setVisibility(View.VISIBLE);
layoutProgress.setVisibility(View.GONE);
progressBar.setIndeterminate(false);
super.onPageFinished(view, url);
}
public void but(View v){
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
layoutProgress.setVisibility(View.VISIBLE);
progressBar.setIndeterminate(true);
super.onPageStarted(view, url, favicon);
}
});
if(isOnline()) {
webView.loadUrl("http://testsite.com/");
} else {
String summary = "<html><body><font color='red'>No Internet Connection</font></body></html>";
webView.loadData(summary, "text/html", null);
toast("No Internet Connection.");
}
}
private void toast(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
} else {
super.onBackPressed();
}
}
private boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
return (netInfo != null && netInfo.isConnected());
}
public void but(View v){
webView.loadUrl("http://testsite.com/");
}
}

if the url changes then use shouldOverrideUrlLoading with some regex
so
List<String> validUrls = new LinkedList<>();
validUrls.add("https://www\\.google\\.com/*");
validUrls.add("https://www\\.facebook\\.com/*");
#Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (isValidUrl(url)) {
return false;
}
return true;
}
private boolean isValidUrl(String url) {
for (String validUrl : validUrls) {
Pattern pattern = Pattern.compile(validUrl, Pattern.MULTILINE);
Matcher matcher = pattern.matcher(url);
if (matcher.find()) {
return true;
}
}
return false;
}
would match against any www.google.com or facebook.com urls

You can intercept the urls that are opened from the webview, I don't know if it would work with the popup:
WebViewClient client= new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
if (url.equals("popupURL"){
return true;
}
return false;
}
}
webView.setWebViewClient(client);

How to get back refreshed web view after onReceivedError

I am developing small app where I am calling webpage.
I override WebViewClient as I wants to open webpage in same view.
My problem is if there is any problem occur(Internet connection breaks or server is disconnected) then I am showing custom error page.
But when Internet is connected it shows same error page, not refreshed web page.
Here is my code:
WebView questionweb;
String questionurl;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
DetectConnection detectConnection = new DetectConnection(getApplicationContext());
ActionBar bar = getActionBar();
// for color
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#5b5959")));
questionweb = (WebView) findViewById(R.id.webView1);
if (!DetectConnection.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "No Internet!", Toast.LENGTH_SHORT).show();
AlertDialog alertDialog = new AlertDialog.Builder(
MainActivity.this).create();
// Setting Dialog Title
alertDialog.setTitle("Internet Connection");
// Setting Dialog Message
alertDialog.setMessage("Please Check Internet Connection");
// Setting OK Button
alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// Write your code here to execute after dialog closed
Intent intent = new Intent(Settings.ACTION_WIFI_SETTINGS);
MainActivity.this.startActivity(intent);
}
});
// Showing Alert Message
alertDialog.show();
} else {
questionweb.getSettings().setJavaScriptEnabled(true);
// loads the WebView completely zoomed out
questionweb.getSettings().setLoadWithOverviewMode(true);
questionweb.getSettings().setUseWideViewPort(true);
// override the web client to open all links in the same webview
questionweb.setWebViewClient(new MyWebViewClient());
questionweb.setWebChromeClient(new MyWebChromeClient());
questionweb.addJavascriptInterface(new JavaScriptInterface(this),
"Android");
// load the home page URL
questionweb.loadUrl("http://10.2.1.119:8081/OnlineExamV2/login/loginpage");
}
// I am calling this to refresh the webpage
questionweb.loadUrl("javascript:window.location.reload( true )" );
}
private class MyWebViewClient extends WebViewClient {
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
hideErrorPage(view);
}
private void hideErrorPage(WebView view) {
String customErrorPageHtml = "<html><body><table width=\"100%\" height=\"100%\" border=\"0\" cellpadding=\"0\" cellspacing=\"0\">"

}

}
}

new AlertDialog.Builder(view.getContext()).setMessage(message)
.setCancelable(true).show();
result.confirm();
return true;
}
}
How to get refreshed web page When internet is back.

Maybe you can give your own BroadcastReceiver class a shot.
Try it like this (totally untested):
1.) GlobalState class:
public GlobalState {
public static boolean isOnline = true;
public static String lastUrl = "";
}
2.) Save your last url and connection-state in onReceivedError:
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
super.onReceivedError(view, errorCode, description, failingUrl);
GlobalState.isOnline = false;
GlobalState.lastUrl = failingUrl;
hideErrorPage(view);
}
3.) Implement a callback in your activity class (i do not know the name, so i called it MainActivity.java):
public class MainActivity extends Activity implements IConnectionCallback {
private ConnectionBroadReceiver cbr = null;
#Override
protected void onCreate(Bundle savedInstanceState) {
//some code...
cbr = new ConnectionBroadReceiver (this);
registerReceiver(cbr, new IntentFilter(ConnectivityManager.CONNECTIVITY_ACTION));
//some more code...
}
//this method will be triggered by ConnectionBroadCastReceiver
#Override
public void reload() {
//now reload your webview:
questionweb.loadUrl(GlobalState.lastUrl);
}
}
4.) Define your Interface callback:
public interface IConnectionCallback {
public void reload();
}
5.) Last but not least the ConnectionBroadReceiver class:
public class ConnectionBroadReceiver extends BroadcastReceiver {
private IConnectionCallback callback = null;
public ConnectionBroadReceiver (IConnectionCallback callback) {
this.callback = callback;
}
#Override
public void onReceive(Context context, Intent intent) {
ConnectivityManager cm = (ConnectivityManager)
context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
// lets check the connection
if (netInfo != null && netInfo.isConnectedOrConnecting()) {
//when last state was the offline state (GlobalState.isOnline== false),
//lets trigger the callback
if (GlobalState.isOnline == false) {
callback.reload();
}
GlobalState.isOnline = true;
} else {
GlobalState.isOnline = false;
}
}
