I have internet permission in my manifest, I am trying to search for "facebook" on the searchbar of my webview, but the problem is, for the 50% searches, It does not load the search request! this is so weird and frustrating. I implemented everything correctly and checked everything 3 times, but no luck. every time I search for the same on other browsers, It always works. but when I search on my webview, It sometimes loads the page, and most of the times, progress bar shows loading, and disappears as if the page has actually loaded, but it is still white. Why is this happening???
public class MainActivity extends AppCompatActivity {
private EditText searchEditText;
private ProgressBar progressBar;
private WebView webView;
private String SearchString = "https://www.google.co.in/search?q=";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
progressBar = (ProgressBar) findViewById(R.id.progressBar);
progressBar.setMax(100);
webView = (WebView) findViewById(R.id.webView);
webView.setWebViewClient(new WebViewClientDemo());
webView.setWebChromeClient(new WebChromeClientDemo());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("about:blank");
// use keyboard go button to search
searchEditText = (EditText) findViewById(R.id.searchfield);
searchEditText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
public boolean onEditorAction(TextView arg0, int arg1, KeyEvent arg2) {
CustomSearch();
return false;
}
});
}
private class WebViewClientDemo extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
progressBar.setProgress(100);
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressBar.setVisibility(View.VISIBLE);
progressBar.setProgress(0);
}
#Override
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(getBaseContext(), "page error. please try again!", Toast.LENGTH_SHORT).show();
super.onReceivedError(view, errorCode, description, failingUrl);
}
}
private class WebChromeClientDemo extends WebChromeClient {
public void onProgressChanged(WebView view, int progress) {
progressBar.setProgress(progress);
}
public void CustomSearch() {
searchEditText = (EditText) findViewById(R.id.searchfield);
String url = searchEditText.getText().toString();
url = SearchString + url.replace(" ", "+");// replace_spaces_with_a_"+"_sign(prefix)
webView.loadUrl(url);
}
Did you try encoding your search text, as per my understanding you need to encode the search string.

I developed a website for my entreprisee and I work almost exclusively with PHP
So the Java language (and android studio) is a really new for me
Despite this I have to create an APK to use the website (in order to block the android home on this site)
I would like to know how to generate errors in order to test this function
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
MainActivity.java
public class MainActivity extends AppCompatActivity {
WebView webView;
SwipeRefreshLayout swipe;
ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
progressBar = (ProgressBar) findViewById(R.id.awv_progressBar);
swipe = (SwipeRefreshLayout) findViewById(R.id.swipe);
LoadWeb();
progressBar.setMax(100);
progressBar.setProgress(1);
swipe = (SwipeRefreshLayout) findViewById(R.id.swipe);
swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
#Override
public void onRefresh() {
webView.reload();
}
});
webView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
progressBar.setProgress(progress);
}
});
webView.setWebViewClient(new WebViewClient() {
#Override

public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
webView.loadUrl("file:///android_asset/error.html");
}
public void onPageFinished(WebView view, String url) {
//Don't show ProgressBar
progressBar.setVisibility(View.INVISIBLE);
//Hide the SwipeRefreshLayout
swipe.setRefreshing(false);
}
});
}
public void LoadWeb() {
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setAppCacheEnabled(true);
webView.loadUrl("mysite.com");
swipe.setRefreshing(true);
}
#Override
public void onBackPressed() {
if (webView.canGoBack()) {
webView.goBack();
} else {
finish();
}
}
}
One way of doing this could be by adding a proxy(using app like fiddler) which returns custom error code as per your wish for all requests from your device.
In case you do not need specific error codes, just use a random system wide wifi proxy which actually does not exist. In this case, device will try sending data to this proxy but won't find it and you will get a callback in onReceivedError.
I am creating application that use WebView to access a online website. I am stuck where I have to add code to check availability of page.
public class SpartanWeb extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Adds Progrss bar Support
this.getWindow().requestFeature(Window.FEATURE_PROGRESS);
setContentView(R.layout.main);
// Makes Progress bar Visible
getWindow().setFeatureInt(Window.FEATURE_PROGRESS,
Window.PROGRESS_VISIBILITY_ON);
// Get Web view
mWebView = (WebView) findViewById(R.id.webView1);
WebSettings websettings = mWebView.getSettings();
websettings.setJavaScriptEnabled(true);
mWebView.stopLoading();
mWebView.clearCache(true);
mWebView.loadUrl("http://google.com");
mWebView.setHorizontalScrollBarEnabled(false);
mWebView.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
mWebView.setWebViewClient(new WebViewClient());
mWebView.setDownloadListener(new DownloadListener() {
public void onDownloadStart(String url, String userAgent,
String contentDisposition, String mimetype,
long contentLength) {
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setData(Uri.parse(url));
startActivity(intent);
}
});
// onProgressChanged
final Activity MyActivity = this;
mWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// 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);
}
});
}// EOM oc
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
I am trying to add onReceivedError but for some reason custom page is not loading.
/** Called when the activity is first created. */
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl)
{
mWebView.loadUrl("file:///android_asset/error.html");
}
Please advise what to do.
You can call loadErrorPage(view) function in the onReceivedError function.
The following code will load the error content you need to show.Here i am load the html file with loadDataWithBaseURL.
public void loadErrorPage(WebView webview){
if(webview!=null){
String htmlData ="<html><body><div align=\"center\" >"This is the description for the load fail : "+description+"\nThe failed url is : "+failingUrl+"\n"</div></body>";
webview.loadUrl("about:blank");
webview.loadDataWithBaseURL(null,htmlData, "text/html", "UTF-8",null);
webview.invalidate();
}
}
I added onReceivedError to mWebView.setWebViewClient(new WebViewClient so now it's working. Thanks for tips.
mWebView.setWebViewClient(new WebViewClient() {
#Override public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
mWebView.loadUrl("file:///android_asset/error.html");
} });
You can use the following code ..
public class TestResultWebclient extends WebViewClient {
ProgressDialog progressDialog;
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
if (progressDialog == null) {
progressDialog = new ProgressDialog(TermsAndCondsMrupeeActivity.this);
progressDialog.setMessage("Loading...");
progressDialog.show();
}
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
if (progressDialog != null)
try {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
progressDialog = null;
}
} catch (Exception exception) {
exception.printStackTrace();
}
super.onPageFinished(view, url);
}
}
I am developing an Android Application. I want to show web site with WebView. But i don't it. A blank/empty page is opening. The other web site showing but Why this is not showing?
My code is below
Please Help me,
Thanks.
public class MainActivity extends ActionBarActivity{
private WebView ourWebSite;
private ProgressDialog pd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
initViews();
setProgressDialog();
}
private void initViews(){
ourWebSite = (WebView) findViewById(R.id.ada_web_site);
ourWebSite.getSettings().setJavaScriptEnabled(true);
ourWebSite.setWebViewClient(new WebSiteWebViewClient());
ourWebSite.loadUrl("http://fahrikayahantaksi.com/");
}
private void setProgressDialog(){
pd = new ProgressDialog(MainActivity.this);
pd.setMessage(getResources().getString(R.string.loading));
pd.setProgressStyle(ProgressDialog.STYLE_SPINNER);
pd.show();
}
private class WebSiteWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
if (!pd.isShowing()) {
pd.show();
}
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
System.out.println("on finish");
if (pd.isShowing()) {
pd.dismiss();
}
}
#Override
public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {
handler.proceed(); // Ignore SSL certificate errors
}
}
}
I think in your code you missed this suppressLint
#SuppressLint("SetJavaScriptEnabled")
Try to change your code like this.. in this way i am able to load your [page]
private WebView mWebview=null ;
#SuppressLint("SetJavaScriptEnabled")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mWebview = new WebView(this);
mWebview.getSettings().setJavaScriptEnabled(true); // enable javascript
final Activity activity = this;
mWebview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
mWebview.loadUrl("http://fahrikayahantaksi.com/");
setContentView(mWebview );
}
Don't forgot to add the Internet permission in your manifest !!
uses-permission android:name="android.permission.INTERNET" />
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_webview);
String url = getIntent().getStringExtra("url");
webView = new WebView(this);
webView.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, description, Toast.LENGTH_SHORT).show();
}
});
webView.loadUrl("http://docs.google.com/viewer?embedded=true&url=" + url);
setContentView(webView );
}
I used google docs to open pdf.
Im making a Web app.
I want block it's selecting texts.
When I use Facebook application, I can't select text likes the picture's.
Because facebook app, it's a hybrid app.
How can I control...
Is there a any method for blocking text selection??...
When I touch some text which hyper linked,
Webview showing up orange color border, where around the texts,
Can I change it color??? or not showing up...??
This is my very simple webviewClient source..
public WebView webViewDefault;
private Context context = null;
private String strListsURL = URLOperation.strListsURL;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
this.context = this;
webViewDefault = (WebView) findViewById(R.id.mainWeb);
webViewDefault.setVerticalScrollBarEnabled(false);
webViewDefault.setWebViewClient(new MyClient());
webViewDefault.loadUrl(strListsURL);
private class MyClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView mWebView, String url) {
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
}
#Override
public void onReceivedError(WebView mWebView, int errorCode, String description, String fallingUrl) {
mWebView.loadData("<html>Load Error</html>", "text/html", "utf-8");
}
}
In android webview, it enters the text selecting mode by long press the text. you can override the onPerformLongClick() to take over the control and return true to prevent from entering the webtextview mode.
Simply put how can I make a progress dialog show up every time a new link is clicked in my webview. I have tried many tutorials and methods but every one of them only shows the dialog once, when the app is initially loaded.
Here is my code
mWebView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
view.loadUrl(url);
return true;
}
ProgressDialog dialog = ProgressDialog.show(myActivity.this, "",
"Loading. Please wait...", true);
#Override
public void onPageFinished(WebView view, String url) {
dialog.dismiss();
}
check out this:
wvCouponsAndOffers.setWebViewClient(new WebViewClient() {
ProgressDialog progressDialog = new ProgressDialog(CouponsWebViewUI.this);
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
progressDialog.setMessage(StringConstants.PROGRESS_DIALOG_MSG);
progressDialog.setCancelable(false);
progressDialog.setOnKeyListener(new OnKeyListener(){
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_SEARCH) {
return true;
}
else
return false;
}});
progressDialog.show();
}
public boolean shouldOverrideUrlLoading(WebView view, String url) {
progressDialog.setMessage(StringConstants.PROGRESS_DIALOG_MSG);
progressDialog.setCancelable(false);
progressDialog.setOnKeyListener(new OnKeyListener(){
#Override
public boolean onKey(DialogInterface dialog, int keyCode,
KeyEvent event) {
if(keyCode == KeyEvent.KEYCODE_SEARCH) {
return true;
}
else
return false;
}});
progressDialog.show();
view.loadUrl(url);
return true;
}
public void onPageFinished(WebView view, String url) {
if (progressDialog.isShowing()) {
progressDialog.dismiss();
}
}
});
Try this,
// Let's display the progress in the activity title bar, like the
// browser app does.
getWindow().requestFeature(Window.FEATURE_PROGRESS);
webview.getSettings().setJavaScriptEnabled(true);
final Activity activity = this;
webview.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different scales.
// The progress meter will automatically disappear when we reach 100%
activity.setProgress(progress * 1000);
}
});
webview.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
Toast.makeText(activity, "Oh no! " + description, Toast.LENGTH_SHORT).show();
}
});
webview.loadUrl("http://slashdot.org/");
And if you want to make your own progressDialog then
webView.setWebViewClient(new WebViewClient() {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url)
{
// Start PROGRESS DIALOG
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
//HIDE PROGRESS DIALOG LOADING IT HAS FINISHED
}
});
And let me know what happen..
