I'm facing with a very very strange problem: I'm trying to load a webview in a fragment, but I sware I can't find a way to make it working and I have absolutely any idea about the reason. The strange is that the same identical code works if run in an Activity
this is my very basic layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin">
<WebView
android:id="@+id/webview"
android:background="@color/black"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
this is the activity where the code works
public class ProvaWebview extends Activity {
WebView wv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_prova_webview);
wv=(WebView)findViewById(R.id.webview);
WebSettings settings=wv.getSettings();
wv.setWebChromeClient(new WebChromeClient() {
});
final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML();
settings.setJavaScriptEnabled(true);
wv.loadDataWithBaseURL("", html, mimeType, encoding, "");
}
@Override
public void onBackPressed() {
super.onBackPressed();
wv.clearHistory();
wv.clearCache(true);
wv.loadUrl("about:blank");
wv.pauseTimers(); //new code
wv = null;
}
public String getHTML() {
String html = "<iframe width=\"100%\" height=\"100%\" src=\"https://www.youtube.com/embed/hEFqVV5q44E?rel=0&controls=0&showinfo=0\" frameborder=\"0\" allowfullscreen></iframe>";
return html;
}
}
and this is the fragment where the code don't work
public class FrTabDescriptionWebView extends Fragment {
public static final String TAG = FrTabDescriptionWebView.class.getName();
private WebView wv;
public static FrTabDescriptionWebView newInstance() {
FrTabDescriptionWebView fragment = new FrTabDescriptionWebView();
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
public FrTabDescriptionWebView() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
return inflater.inflate(R.layout.activity_prova_webview, null);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
wv = (WebView) view.findViewById(R.id.webview);
WebSettings settings = wv.getSettings();
wv.setWebChromeClient(new WebChromeClient() {
});
final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML();
settings.setJavaScriptEnabled(true);
wv.loadDataWithBaseURL("", html, mimeType, encoding, "");
}
public String getHTML() {
String html = "<iframe width=\"100%\" height=\"100%\" src=\"https://www.youtube.com/embed/hEFqVV5q44E?rel=0&controls=0&showinfo=0\" frameborder=\"0\" allowfullscreen></iframe>";
return html;
}
}
what the hell am I doing wrong??
I also tryied to use a WebViewFragment replacing wv with getWebView but the problem still remain
thankyou for your help

I found the problem:
I had another Activity showing a WebView embedding a youtube video, and to make it stopping when closing the Activity I was using this code in the finish method
wv.clearHistory();
wv.clearCache(true);
wv.loadUrl("about:blank");
wv.pauseTimers();
wv = null;
avoiding this code made the fragment working. I think that the real code causing the problem was
wv.pauseTimers();
CONFIRMATION
After some testing I can confirm that the real problem was
wv.pauseTimers();
removing this line everything works as expected, to make a youtube video stop playing this code works fine
wv.clearHistory();
wv.clearCache(true);
wv.loadUrl("about:blank");
wv = null;

Move your all code from onCreated(..)
to onCreateView(...)
. and also remove
super.onCreateView(inflater, container, savedInstanceState);
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.activity_prova_webview, null);
wv = (WebView) view.findViewById(R.id.webview);
WebSettings settings = wv.getSettings();
wv.setWebChromeClient(new WebChromeClient() {
});
final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML();
settings.setJavaScriptEnabled(true);
wv.loadDataWithBaseURL("", html, mimeType, encoding, "");
return view;
}
