You have to decode HTML:
URL yahoo = new URL("http://www.yahoo.com/");
BufferedReader in = new BufferedReader(
new InputStreamReader(
yahoo.openStream()));
String inputLine;
while ((inputLine = in.readLine()) != null)
System.out.println(inputLine);
in.close();
After that get Image Tag from it then you can get mages from it and write to sd card.

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();

Google sign in not working android webview app

I've created Android App with the webview. When trying to sign in with Google, it first asks for username & password, then the screen with the message 'Please close this window' shows up & nothing happens.
Also, the user is not logged in.
P.S. This works absolutely fine with my mobile website which itself is ported to Android Webview App. Can anyone tell why that doesn't work? I'm completely new to Android.

Two things in webview create problems in google sign-in.
Google doesn't allow us to sign-in from webview nowadays. So, User-Agent needs to be customized.
Popup handling in webview isn't appropriate. So, a function override is needed.
Using custom User-Agent and an AlertDialog in WebChromeClient to handle popups solve the issues for me.
Here's the full code:
public class MainActivity extends AppCompatActivity {
private Context contextPop;
private WebView webViewPop;
private AlertDialog builder;
private String url = "https://example.com";
private WebView webView;
private String userAgent;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webView = findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// to continue loading a given URL in the current WebView.
// needed to handle redirects.
return false;
}
});
webView.loadUrl(url);
WebSettings webSettings = webView.getSettings();
// Set User Agent
//userAgent = System.getProperty("http.agent");
// the upper line sometimes causes "403: disallowed user agent error"
userAgent = "";
webSettings.setUserAgentString(userAgent + "Your App Info/Version");
// Enable Cookies
CookieManager.getInstance().setAcceptCookie(true);
if(android.os.Build.VERSION.SDK_INT >= 21)
CookieManager.getInstance().setAcceptThirdPartyCookies(webView, true);
// WebView Tweaks
webSettings.setJavaScriptEnabled(true);
webSettings.setRenderPriority(WebSettings.RenderPriority.HIGH);
webSettings.setCacheMode(WebSettings.LOAD_DEFAULT);
webSettings.setAppCacheEnabled(true);
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webSettings.setSaveFormData(true);
webSettings.setEnableSmoothTransition(true);
webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
// Handle Popups
webView.setWebChromeClient(new CustomChromeClient());
webSettings.setJavaScriptCanOpenWindowsAutomatically(true);
webSettings.setSupportMultipleWindows(true);
contextPop = this.getApplicationContext();
}
#Override
public void onBackPressed() {
if(webView.canGoBack()) {
webView.goBack();
}
else {
//super.onBackPressed();
// Terminate the app
finishAffinity();
System.exit(0);
}
}
class CustomChromeClient extends WebChromeClient {
#Override
public boolean onCreateWindow(WebView view, boolean isDialog,
boolean isUserGesture, Message resultMsg) {
webViewPop = new WebView(contextPop);
webViewPop.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// to continue loading a given URL in the current WebView.
// needed to handle redirects.
return false;
}
});
// Enable Cookies

cookieManager.setAcceptCookie(true);
if(android.os.Build.VERSION.SDK_INT >= 21) {
cookieManager.setAcceptThirdPartyCookies(webViewPop, true);
cookieManager.setAcceptThirdPartyCookies(webView, true);
}
WebSettings popSettings = webViewPop.getSettings();
// WebView tweaks for popups
webViewPop.setVerticalScrollBarEnabled(false);
webViewPop.setHorizontalScrollBarEnabled(false);
popSettings.setJavaScriptEnabled(true);
popSettings.setSaveFormData(true);
popSettings.setEnableSmoothTransition(true);
// Set User Agent
popSettings.setUserAgentString(userAgent + "Your App Info/Version");
// to support content re-layout for redirects
popSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.SINGLE_COLUMN);
// handle new popups
webViewPop.setWebChromeClient(new CustomChromeClient());
// set the WebView as the AlertDialog.Builder’s view
builder = new AlertDialog.Builder(MainActivity.this, AlertDialog.THEME_DEVICE_DEFAULT_LIGHT).create();
builder.setTitle("");
builder.setView(webViewPop);
builder.setButton("Close", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int id) {
webViewPop.destroy();
dialog.dismiss();
}
});
builder.show();
builder.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE|WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
WebView.WebViewTransport transport = (WebView.WebViewTransport) resultMsg.obj;
transport.setWebView(webViewPop);
resultMsg.sendToTarget();
return true;
}
#Override
public void onCloseWindow(WebView window) {
//Toast.makeText(contextPop,"onCloseWindow called",Toast.LENGTH_SHORT).show();
try {
webViewPop.destroy();
} catch (Exception e) {
Log.d("Webview Destroy Error: ", e.getStackTrace().toString());
}
try {
builder.dismiss();
} catch (Exception e) {
Log.d("Builder Dismiss Error: ", e.getStackTrace().toString());
}
}
}
}

mainWebView.getSettings().setUserAgentString("example_android_app");
fixed it for me
just changed mainWebView to what my webview was called. In my case, i set it to
webView.getSettings().setUserAgentString("example_android_app");

adding custom progress bar in android webview

I need a progress bar at the centre of my android webview it must be shown before the page loads and hides when the page is loaded. How can it be done? Can anyone help me?
This is my code for webview:
Bundle extras = getIntent().getExtras();
String title;
final String url;
if (!Datacon.checkInternetConnection(this)) {
Toast.makeText(getApplicationContext(), "Check your Internet Connection!", Toast.LENGTH_LONG).show();
} else {
if (extras != null) {
title = extras.getString("title");
url = extras.getString("url");
TextView text=(TextView) findViewById(R.id.textView1);
text.setText(title);
final WebView myWebView =(WebView)findViewById(R.id.WebView);
myWebView.loadUrl(url);
myWebView.getSettings().setLoadWithOverviewMode(true);
myWebView.getSettings().setUseWideViewPort(true);
myWebView.getSettings().setBuiltInZoomControls(true);
myWebView.getSettings().setLayoutAlgorithm(LayoutAlgorithm.SINGLE_COLUMN);
loadingProgressBar=(ProgressBar)findViewById(R.id.progressbar_Horizontal);
myWebView.setWebViewClient(new WebViewClient(){
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return false;
}
});
Button refresh = (Button) actionBar.getCustomView().findViewById(R.id.but2);
refresh.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
myWebView.loadUrl(url);
}
});
}
}}
}

You need to override a couple of more methods in the WebViewClient :
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
loadingProgressBar.setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
loadingProgressBar.setVisibility(View.GONE);
}
I'm assuming loadingProgressBar is a class field.
PS: As a side note I believe you overriding shouldOverrideUrlLoading is unnecessary. The default behaviour is to load the url, as you instruct it to do.

private void initializeProgressBar() {
if (progressBar == null){
progressBar = new ProgressDialog(this);
progressBar.setMessage(Constants.LOADING_MESSAGE);
progressBar.setCancelable(false);
}
}
Handler peogressBar = new Handler(){
public void handleMessage(android.os.Message msg) {
try{
switch (msg.what) {
case 1:
initializeProgressBar();
if(!progressBar.isShowing())
progressBar.show();
break;
case 2:
if (progressBar != null && progressBar.isShowing()) {
progressBar.dismiss();
progressBar = null;
}
break;
}
}catch(Exception e){
e.printStackTrace();
}
};
};
wv_graphLink = (WebView) findViewById(R.id.wv_graphLink);
wv_graphLink.getSettings().setJavaScriptEnabled(true);
wv_graphLink.getSettings().setBuiltInZoomControls(true);
wv_graphLink.getSettings().setSupportZoom(true);
wv_graphLink.setInitialScale(1);
wv_graphLink.getSettings().setLoadWithOverviewMode(true);
wv_graphLink.getSettings().setUseWideViewPort(true);
// wv_graphLink.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
// wv_graphLink.setScrollbarFadingEnabled(false);
peogressBar.sendEmptyMessage(1);
wv_graphLink.setWebChromeClient(new WebChromeClient(){
public void onProgressChanged(WebView view, int progress) {
if(progress == 100){
peogressBar.sendEmptyMessage(2);
}
}
});
wv_graphLink.loadUrl("Your url");

button to display url not working anymore

i was working on a webView had it working but the flash videos didn't work.
After a little bit of searching i found a webview code that displays videos.
webview video
this is my old code
private static final String LOG_TAG = "Web";
private WebView mWebView;
public static final String URL = "";
#Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web);
mWebView = (WebView) findViewById(R.id.webView);
WebSettings webSettings = mWebView.getSettings();
webSettings.setSavePassword(false);
webSettings.setSaveFormData(false);
webSettings.setJavaScriptEnabled(true);
webSettings.setSupportZoom(false);
String turl = getIntent().getStringExtra(URL);
mWebView.loadUrl(turl);
;
}
#Override
public void onBackPressed() {
finish();
}
/**
* Provides a hook for calling "alert" from javascript. Useful for debugging
* your javascript.
*/
final class MyWebChromeClient extends WebChromeClient {
#Override
public boolean onJsAlert(WebView view, String url, String message,
JsResult result) {
Log.d(LOG_TAG, message);
result.confirm();
return true;
}
}
so i replaced it with the mainactivity from the source and added
String turl = getIntent().getStringExtra(URL);
and
public static final String URL = "";
and made some changes so it loads the class names i use
so now i've got this
private WebView webView;
public static final String URL = "";
private FrameLayout customViewContainer;
private WebChromeClient.CustomViewCallback customViewCallback;
private View mCustomView;

i use this code for my button to open the url in webview
public void onClick(View v) {
switch (v.getId()) {
case R.id.button1:
Intent k = new Intent(this, Web.class);
k.putExtra(com.papers.test.Web.URL,
"http://www.telegraaf.mobi");
startActivity(k);
break;
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.onlinekranten);
View secondButton = findViewById(R.id.button1);
secondButton.setOnClickListener(this);
}

Its looks like your button needs to be declared
I like to do it above onCreate to use it any where
Button secondButton;
