where you want to show progressbar.
if(!checkNetwork()){
show progressbar or you want to show toast also like no internet connection avilable please try again
}
else {

When you popBackStack() the fragment from back stack will appear on screen so you need to listen for Back stack changes.
getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
#Override
public void onBackStackChanged() {
Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.containerFrame);
if (fragment != null) {
// check for fragment and set the drawer state
if(fragment instanceof Frag1){
// set drawer state for 1
}else if(fragment instanceof Frag2){
// set drawer state for 2
}
}
}
});

I check all the forum but not find a solution | "Open external links of my webview in browser and not in app" does not work

In your method LoadWeb() there is an error because your WebView should have only one WebViewClient and only one WebChromeClient. So what happens is, if you use the method wv.setWebViewClient(new YourWebViewClient()); more than once what happens is that all other methods set before that are ignored because you can set it only once.For your case:
You set the WebViewClient Three (3) times:
wv.setWebViewClient(new HelpClient()); //First time
wv.setWebViewClient(new MyAppWebViewClient()); //Second time
And the last time you set it down in your same method you set another like:
wv.setWebViewClient(new WebViewClient(){
public void onPageFinished(WebView view, String url){
swipe.setRefreshing(false);
}
});
So what happens is that the two previous methods were ignored and the only method that was working was the last one (the third) only. That's why I asked you to put the second method down to setWebClient((new MyAppWebViewClient()); so as to ignore the previous!
THE SOLUTION
Now you know we have to set only one WebViewClient for your webView we have to make only ONE Class that will be used to and do the job of all three other WebViewClient by overriding all the required methods. Make this class inside your activity but oustide your any method (just like how you have done when making in HelpClient() Class). Here is Our Class Please make sure you read the Comments in it!
private class NewWebViewClient extends WebViewClient {
//Now we have only one class to do a job of all the other three!
#Override
public void onPageFinished(WebView view, String url) {
/*I here do whatever you want to do when the page has finished loading! Do it here inside this method and it will work may be control the framelayout visibility For example lets setRefreshing false to our swipe()*/
swipe.setRefreshing(false);
//.....add more methods you want here when the page loading is finished
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
/*In this method we are going to tell the android system what kind of link we want and what kind of link we dont want for that what we want we will handle for the extra the browser should do so!*/
if (Uri.parse(url).getHost().endsWith("example.com")) {
//if the code gets here this is your link then right? Lets do whatever we want with our link and logic for example lets set framelayout visible or doing anything this link's host is example.com!
frameLayout.setVisibility(View.VISIBLE);
return false;
} else {
//Ooops This link is not yours lets just open browsers right
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
}
After your class is beautiful then lets just set our WebViewClient only ONCE.
wv.setWebViewClient(new NewWebViewClient());
You can just ignore the WebChromeClient because you set it only once you are good. Comment below if you find any difficulties!

I hope removing the this line
wv.setWebViewClient(new MyAppWebViewClient());
will solve the problem for you.

You are using two instances of WebViewClient ,remove one ,
private class MyAppWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
Log.d("TAG",url);
if(Uri.parse(url).getHost().equals("example.com")) {
return false;
}
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);//add the brakpoint here
Log.d("TAG","Starting activity");
return true;
}
}
just use this

how could I refresh a webview?

so i made a website which could be turned into mobile app simply by using webview. when the first time i install the apk, it work perfectly well but the problem is after that, the web is just static or it's not loaded anymore.
it just open up the same content like the first time i install it even though i already change the whole website. i don't know if the problem was with the webview or with the android.
i already try made a auto refresh/autoreload function in php but it only work in mobile browser and didn't work in my app...
anyone know any solution?
since i'm a newbie in android developping i'll put the whole code of my main activity

The webView caches all the Contents of the Site , so that it doesn't need to download images etc.
For you to get the updations you need to maintain versioning your files and have a cache-control = max-age on yout index.html file

mwebView.loadUrl("about:blank");
mwebView.loadUrl("http://192.168.94.2/ee1/");
Load blank page before loading any new url.
So add mwebView.loadUrl("about:blank"); before all your if-else cases.
May this help!

webView.loadUrl("javascript:window.location.reload(true)");
This may help to reload the webview. Thanks

How to stop swipetorefresh progressbar in webview?

I'm new with Android development. I got trouble using SwipeToRefresh option in WebView. I'm trying to solve it from a mounth now and after trying several codes, it's not working. Also Youtube video is not playing in full screen from the WebView...
Here's my question: How to hide SwipeToRefresh ProgressBar and stop running?
Here is my MainActivity class:
public class WebViewActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
private WebView myWebView;
private SwipeRefreshLayout mSwipeRefreshLayout;
//HTML5 video
private View mCustomView;
private int mOriginalSystemUiVisibility;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
OneSignal.startInit(this)
.setNotificationOpenedHandler(new ExampleNotificationOpenedHandler())
.init();
setContentView(R.layout.activity_web_view);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
MobileAds.initialize(getApplicationContext(), "ca-app-pub-App Id");
AdView mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.loadAd(adRequest);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
//WebView
mSwipeRefreshLayout = (SwipeRefreshLayout) findViewById(R.id.refreshlayout);
myWebView = (WebView) findViewById(R.id.webview);
mSwipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
myWebViewSettings();
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
//improve webView performance
myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);

webSettings.setEnableSmoothTransition(true);
myWebView.loadUrl("http://www.youtube.com");
//force links open in webview only
myWebView.reload(); // refreshes the WebView
}
});
myWebView.setWebViewClient(new MyWebViewClient());

I had the same problem and i found the question in another thread:
final SwipeRefreshLayout swipeLayout =
(SwipeRefreshLayout)this.findViewById(R.id.swipeToRefresh);
swipeLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
myWebView.reload(); // refreshes the WebView
if (null != swipeLayout) {
swipeLayout.setRefreshing(false);
}
}
});
