Is it possible to play a Youtube video using WebView in Android - android

I've gone though many tutorials found on Google and none of the answers really work. I would like the video to play in the WebView instead of going though the YouTube app. Any help would be awesome. Thanks.
Code:
public class Youtube extends Activity {
WebView myWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.website);
myWebView = (WebView) findViewById(R.id.webView);
myWebView.loadUrl("http://www.youtube.com");
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.addJavascriptInterface(new WebAppInterface(this), "Android");
myWebView.setWebViewClient(new WebViewClient());
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setSupportZoom(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setLoadWithOverviewMode(true);
getActionBar().setDisplayHomeAsUpEnabled(true);
}
public class WebAppInterface {
Context mContext;
/** Instantiate the interface and set the context */
WebAppInterface(Context c) {
mContext = c;
}
/** Show a toast from the web page */
#JavascriptInterface
public void showToast(String toast) {
Toast.makeText(mContext, toast, Toast.LENGTH_SHORT).show();
}
private class MyWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost()
.equals("http://www.youtube.com")) {
// This is my web site, so do not override; let 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;
}
}
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Check if the key event was the Back button and if there's history
if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {
myWebView.goBack();
return true;
}
// If it wasn't the Back key or there's no web page history, bubble up
// to the default
// system behavior (probably exit the activity)
return super.onKeyDown(keyCode, event);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

Use the new YouTube Android Player API - https://developers.google.com/youtube/android/player
"The API defines methods for loading and playing YouTube videos (and playlists) and for customizing and controlling the video playback experience."
So for using with a Channel, you'd use the regular YoutTube API to get the metadata, and play the videos/playlists with the Player API.

Kindly try working around this code after defining the webView in your layout's xml file:
In the MainActivity, get the instances of WebView controls and convert the iFrame code of the embed YouTube video to a string. Then enable Javascript and load the video iFrame string to the webview instance by using the loaddata() of the WebView.
public class MainActivity extends ActionBarActivity {
private MyWebChromeClient mWebChromeClient = null;
private View mCustomView;
private RelativeLayout mContentView;
private FrameLayout mCustomViewContainer;
private WebChromeClient.CustomViewCallback mCustomViewCallback;
private WebView myWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
myWebView = (WebView) findViewById(R.id.webView);
mWebChromeClient = new MyWebChromeClient();
myWebView.setWebChromeClient(mWebChromeClient);
myWebView.setWebViewClient(new WebViewClient(){
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return false;
}
});
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.loadUrl("https://www.youtube.com/watch?v=7bDLIV96LD4");
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
public class MyWebChromeClient extends WebChromeClient {
FrameLayout.LayoutParams LayoutParameters = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT);
#Override
public void onShowCustomView(View view, CustomViewCallback callback) {
// if a view already exists then immediately terminate the new one
if (mCustomView != null) {
callback.onCustomViewHidden();
return;
}
mContentView = (RelativeLayout) findViewById(R.id.activity_main);
mContentView.setVisibility(View.GONE);
mCustomViewContainer = new FrameLayout(MainActivity.this);
mCustomViewContainer.setLayoutParams(LayoutParameters);
mCustomViewContainer.setBackgroundResource(android.R.color.black);
view.setLayoutParams(LayoutParameters);
mCustomViewContainer.addView(view);
mCustomView = view;
mCustomViewCallback = callback;
mCustomViewContainer.setVisibility(View.VISIBLE);
setContentView(mCustomViewContainer);
}
#Override
public void onHideCustomView() {
if (mCustomView == null) {
return;
} else {
// Hide the custom view.
mCustomView.setVisibility(View.GONE);
// Remove the custom view from its container.
mCustomViewContainer.removeView(mCustomView);

// Show the content view.
mContentView.setVisibility(View.VISIBLE);
setContentView(mContentView);
}
}
}
#Override
public void onBackPressed() {

mWebChromeClient.onHideCustomView();
else if (myWebView.canGoBack())
myWebView.goBack();
else
super.onBackPressed();
}
}

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

Override back button while viewing webview (fragment)

I created a WebView using Fragment; here is my code:
public class MyWebView extends Fragment {
private WebView webView;
#SuppressLint("SetJavaScriptEnabled")
#Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Bundle args = getArguments();
String url = args.getString("url");
webView = (WebView) getView().findViewById(R.id.webView);
webView.setWebViewClient(new MyBrowser());
WebSettings webSettings = webView.getSettings();
webSettings.setSaveFormData(true);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
webSettings.setSupportZoom(true);
webSettings.setBuiltInZoomControls(true);
webSettings.setLoadsImagesAutomatically(true);
webSettings.setJavaScriptEnabled(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webView.loadUrl(url);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.web_view, container, false);
view.setOnKeyListener(new OnKeyListener() {
#Override
public boolean onKey( View v, int keyCode, KeyEvent event ) {
if (keyCode == KeyEvent.KEYCODE_BACK) {
if (webView.canGoBack()) {
webView.goBack();
return true;
}
}
return false;
}
});
return view;
}
private class MyBrowser extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
}
I tried to override onBackPressed() but it seems not to work with Fragment. So I used setOnKeyListener() but it doesn’t work.
Can you tell me why the back button closes the app instead of going back to the previous web page?
The Fragment doesn't receive a callback of the OnBackPressed event. You'll have to make your Activity state aware when your fragment is displayed and communicate back and forth between the activity and the fragment.
You could make your code you're calling in on key a public boolean function for instance and if the fragment is present you interact with it, you continue to return true or false in a similar way which allows you to know on the activity if you should continue with it naturally if there are no more pages to go back.

Set sharing intent using icon in action bar

I want to share the website that the user is viewing in the webview in my app, however any of the tutorials I have followed, it just isn't working. I can get the icon to load in the action bar but it doesn't click. I have had onclick listeners implemented and nothing so far. The app is only meant for ICS or higher so it doesn't need to be backwards compatible with older androids. The code I am putting up is before any share icon is implemented as I want to do it from scratch or to see if anyone has any ideas to what I can do
public class WebActivity extends Activity {
private WebView mWebView = null;
private EditText mInputUrl = null;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
super.onCreate(savedInstanceState);
getWindow().setFeatureInt( Window.FEATURE_PROGRESS, Window.PROGRESS_VISIBILITY_ON);
setContentView(R.layout.activity_web_view);
Intent intent = getIntent();
String thesite = intent.getStringExtra(MainPage.EXTRA_MESSAGE);
mInputUrl = (EditText)findViewById(R.id.input_url);
Button button = (Button)findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String baseurl = "http://";
String url = baseurl + mInputUrl.getText().toString();
mWebView.loadUrl(url);
}
});
mWebView = (WebView) findViewById(R.id.webview);
mWebView.loadUrl(thesite);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.getSettings().setAllowFileAccess(true);
mWebView.getSettings().setPluginState(WebSettings.PluginState.ON);
mWebView.getSettings().setBuiltInZoomControls(true);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setGeolocationEnabled(true);
mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
final Activity MyActivity = this;
mWebView.setWebChromeClient(new WebChromeClient() {
public void onGeolocationPermissionsShowPrompt(String origin, android.webkit.GeolocationPermissions.Callback callback) {
callback.invoke(origin, true, false);
}
public void onProgressChanged(WebView view, int progress)
{
//Make the bar disappear after URL is loaded, and changes string to Loading...
MyActivity.setTitle("Loading...");
MyActivity.setProgress(progress * 100); //Make the bar disappear after URL is loaded
// Return the app name after finish loading
if(progress == 100)
MyActivity.setTitle(R.string.app_name);
}
});
}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
// Check if the key event was the Back button and if there's history
WebView myWebView = (WebView) findViewById(R.id.webview);
if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack()) {
myWebView.goBack();
return true;
}
// If it wasn't the Back key or there's no web page history, bubble up to the default
// system behavior (probably exit the activity)
return super.onKeyDown(keyCode, event);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
// This ID represents the Home or Up button. In the case of this
// activity, the Up button is shown. Use NavUtils to allow users
// to navigate up one level in the application structure. For
// more details, see the Navigation pattern on Android Design:
//
// http://developer.android.com/design/patterns/navigation.html#up-vs-back
//
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
}
Edit
I have used this code to try and get it working, however when I go to click the icon it doesn't do anything at all.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.share_menu, menu);
return true;
}
#Override
public final boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_share:
shareURL();
}
return super.onOptionsItemSelected(item);
}
private void shareURL() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, mWebView.getUrl());
startActivity(Intent.createChooser(shareIntent, "Share This!"));
}
I have found the answer. It was rather simple in the end.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.share_menu, menu);
return true;
}
#Override
public final boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_item_share:
shareURL();
}
if(item.getItemId() == R.id.menu_item_refresh){
mWebView.reload();
return true;
}
return super.onOptionsItemSelected(item);
}
private void shareURL() {
Intent shareIntent = new Intent(Intent.ACTION_SEND);
shareIntent.setType("text/plain");
shareIntent.putExtra(Intent.EXTRA_TEXT, mWebView.getUrl());
startActivity(Intent.createChooser(shareIntent, "Share This Website!"));
}
}
This also allowed me to have a refresh button too.
I don't see any override for onCreateOptionsMenu(..), are you sure you have added your ActionItems? Take a look at http://developer.android.com/guide/topics/ui/actionbar.html.

YouTube Video not playing in WebView

YouTube Video not playing in WebView.
It my first app ,I Want to do a webview.
When I open YouTube the video not playing, is loading but not playing.
Is loading all the time.
Thank you so much for helping.
Java:
public class MainActivity extends Activity {
private WebView mWebView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
mWebView.setWebViewClient(new HelloWebViewClient());
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView webview, String url)
{
webview.loadUrl(url);
return true;
}}
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack())
{
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
} }
Xml:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
Seems like duplicate of play youtube video in WebView and YouTube Video not playing in WebView - Android
To make it work via WebView, I used the following two steps (version 4.2.2/Nexus 4):
On shouldOverrideUrlLoading I added webview.setWebChromeClient(new WebChromeClient());
In AndroidManifest.xml for activity tag I added android:hardwareAccelerated="true"
AndroidManifest.xml should also contain Internet permission.
While exact steps with playing video via WebView can be specific to device and Android version, there are also other alternatives to WebView, like VideoView or using Youtube Android Player API.
EDIT1
As for pause and full screen, this is actually a second link I mentioned in the beginning. To make it easier, I am posting code that worked on my Nexus.

Adding webchrome client solves the issue,
web = (WebView) vi.findViewById(R.id.offer_webView1);
web.loadUrl(getResources().getString(R.string.videolink));
web.getSettings().setJavaScriptEnabled(true);
// web.getSettings().setDomStorageEnabled(true);
web.getSettings().setAllowContentAccess(true);
WebSettings webSettings = web.getSettings();
webSettings.setPluginState(WebSettings.PluginState.ON);
webSettings.setUseWideViewPort(true);
webSettings.setLoadWithOverviewMode(true);
web.canGoBack();
web.setWebChromeClient(new WebChromeClient() {});

WebView inside Fragment - Back button?

I created a small Android 4 application with fragments.
In all these fragments I have some webviews and if I click a different fragment I want a different website to load.
I have right now TabOne.java ; TabTwo.java ; TabThree.java and so on.
I was also wondering : Can I make this application without needing a TabOne.java, TabTwo.java and so on; only from MainActivity.java? I mean, to have a single WebView, and when clicking different Tabs, this WebView to load different Url (according to the selected Tab).
If this is not possible, can you tell me what is wrong here (TabOne.java) :
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.tabone, container, false);
myWebView = (WebView) view.findViewById(R.id.webview);
myWebView.getSettings().setPluginsEnabled(true);
myWebView.loadUrl("http://m.stirileprotv.ro");
myWebView = new WebView(getActivity());
myWebView.setOnKeyListener(new OnKeyListener(){
#Override
public boolean onKey(View v, int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && myWebView.canGoBack())
{
myWebView.goBack();
return true;
}
return false;
}
});
myWebView.setWebViewClient(new WebViewClient() {
#Override public boolean shouldOverrideUrlLoading(WebView view, String url) {
if (Uri.parse(url).getHost().equals("m.stirileprotv.ro")) {
myWebView.loadUrl(url);
return true;
}
else
{
return false;
}
}
});
return view;
}
This is what i did.
In the fragment, declare the webview reference as static-
public static WebView mWebView;
public WebFragment() {
// Required empty public constructor
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v=inflater.inflate(R.layout.fragment_web, container, false);
mWebView = (WebView) v.findViewById(R.id.webview);
mWebView.loadUrl("https://google.com");
// Enable Javascript
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
// Force links and redirects to open in the WebView instead of in a browser
mWebView.setWebViewClient(new WebViewClient());
return v;
}
public boolean canGoBack() {
return mWebView.canGoBack();
}
public void goBack() {
mWebView.goBack();
}
}
Now, In the parent activity -
#Override
public void onBackPressed() {
WebFragment fragment = new WebFragment();
if (fragment.mWebView.canGoBack()) {
fragment.mWebView.goBack();
} else {
super.onBackPressed();
}
}
What I did was implement it within the activity and then have a public static so:
In the main activity:
public class MainActivity extends FragmentActivity{
public static WebView myWebView;
...
#Override
public void onBackPressed() {
if (getSupportFragmentManager().findFragmentByTag("yourtag") != null) {
if(myWebView.canGoBack())
myWebView.goBack();
else {
super.onBackPressed();
}
}
else
super.onBackPressed();
}
...
}
and to reference it within the fragment:
MainActivity.myWebView = (WebView) getView().findViewById(R.id.webview);
and be sure when you create the fragment you add a tag
transaction.replace(R.id.yourfragid, newfragment, "yourtag");
