WebView is not loading webpage

I am using WebView for loading a website. But it is very slow and is leaking when specific websites are loaded.
I am loading WebView with the following code.
#Override
protected void onNewIntent(Intent intent) {
if (intent.getStringExtra("url") != null) {
webView.loadurl(intent.getStringExtra("url"));
}
}
But I am calling webView.loadUrl(Config.URL); (Config.URL may contain same url as specified above) in onCreate() method after initializing WebView with the following.
this.webView = (WebView) findViewById(R.id.wv);
this.webView.getSettings().setJavaScriptEnabled(true);
this.webView.getSettings().setLoadsImagesAutomatically(true);
this.webView.getSettings().setDomStorageEnabled(true);
this.webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
MyClient client = new MyClient(WebActivity.this, (ProgressBar)findViewById(R.id.progressBar));
webView.setWebViewClient(client);
Loading a from onCreate() is working fine (not fine, it's too slow). But
the same URL that is loading from onNewIntent() is not working!!!.
After I did this inonNewIntent() no URLs got loaded using
webView.loadurl() and the current page is getting immovable. ie. the
scrollbars are moving in WebView but page is not scrolling. I tested
the same URL in onCreate() and it is working.
For doing that I am passing url with
intent.putExtra("url", Config.URL+targetUrl);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP);
with the pending intent from the notifications. Although it is working in some devices i.e Google Nexus. But it is not working on most of the phones.
I have

#Override

The question is: What is the problem when using loadurl() method in onNewIntent()?

Try this from where you loads webview
web.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
return super.shouldOverrideUrlLoading(view, url);
}
});

You can use the webclient to handle the webview. Here I include the javascript with loading.
String aboutURL="YOUR URL";
final ProgressDialog pd = ProgressDialog.show(, "", "Please wait", true);
WebSettings settings=Webview.getSettings();
settings.setJavaScriptEnabled(true);
settings.setAppCacheEnabled(true);
settings.setDomStorageEnabled(true);
settings.setLoadsImagesAutomatically(true);
settings.setDatabaseEnabled(true);
settings.setRenderPriority(WebSettings.RenderPriority.HIGH);
settings.setCacheMode(WebSettings.LOAD_NO_CACHE);
settings.setSupportZoom(true);
settings.setBuiltInZoomControls(true);
Webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon)
{
pd.show();
}
#Override
public void onPageFinished(WebView view, String url) {
pd.dismiss();
}
});
Webview.loadUrl(aboutURL);
Here Loading is processed based on network

Use Handler to post a delay action as below will fix this, but I don't known why.
new Handler().post(webView.loadurl(url));

How to Handle WebView in Android 4.2 and 4.1

My Webview works in android 4.4.4 and higher.How can I handle it in all android devices?!
I mean I tried many ways to show PaymentGateWay in Webview but it`s just shown url address in webview page(Cant Load Url).how can I do it with this code?

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 cookieManager = CookieManager.getInstance();
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());
}
}
}
}

How to load the data in webview page by page in android

I am using webview to display the html data.It is working fine if the data is less(less than 1 mb)..I am using following code
mDecryptDataWv.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url) {
DebugLog.i(TAG, "Processing webview url click...");
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
//showProgressDialog();
DebugLog.i(TAG, "************onPageStarted **************");
}
#Override
public void onPageFinished(WebView view, String url) {
DebugLog.i(TAG, "************onPageFinished **************");
if (mProgressDialog != null) {
if (mProgressDialog.isShowing()) {
DebugLog.i(TAG, "mProgressDialog ::::::stopping");
mProgressDialog.dismiss();
mProgressDialog = null;
}
}
If the data is more then 1MB it is taking more time to complete the loading.so my intention is to load the data page by page upon user scrolling with progress dialog..Can anyone has idea?
