I am building one app for my online radio station with iframe the site. But how I will add a progress status or animation image so that it's start on loading & end after load the site ? Here is the code I am using now:
package com.jibon.tarabradio;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class MainActivity extends Activity {
#SuppressLint({ "SetJavaScriptEnabled", "NewApi" }) #Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
WebView webview;
webview = (WebView) findViewById(R.id.webview);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
webview.getSettings().setAllowUniversalAccessFromFileURLs(true);
webview.loadUrl("http://hoicoimasti.com/radio/");
}
}
I also have another problem. When I select one country from drop down menu showing inside the app it's open different browser. How do I stop that & open inside the app ? Thanks in advance.
Just did it :) & solved other problem also :)
package com.jibon.tarabradio;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Bitmap;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends Activity {
WebView webview;
ProgressBar progressBar;
#SuppressLint({ "SetJavaScriptEnabled", "NewApi" })
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
webview = (WebView) findViewById(R.id.webview);
progressBar = (ProgressBar) findViewById(R.id.progress_bar);
webview.setWebViewClient(new myWebClient());
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
webview.getSettings().setAllowUniversalAccessFromFileURLs(true);
webview.loadUrl("http://hoicoimasti.com/radio/");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override

// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
}

Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
view.getContext().startActivity(intent);
return true;
}
}
Where is the error? :D
It keeps opening up in the browser.
In the following line:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(url));
you're asking Android to open a URL using the intent constant ACTION_VIEW - so it defaults to the external browser.
Here a full example (taken from here) that shows how to open the url using a WebViewClient:
package com.paresh.webviewclientdemo;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
/*
* Demo of creating an application to open any URL inside the application and clicking on any link from that URl
should not open Native browser but that URL should open in the same screen.
*/
public class WebViewClientDemoActivity extends Activity {
/** Called when the activity is first created. */
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
web = (WebView) findViewById(R.id.webview01);
web.setWebViewClient(new myWebClient());
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.google.com");
}
public class myWebClient extends WebViewClient
{
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
}
// To handle "Back" key press event for WebView to go back to previous screen.
#Override
public boolean onKeyDown(int keyCode, KeyEvent event)
{
if ((keyCode == KeyEvent.KEYCODE_BACK) && web.canGoBack()) {
web.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
The progress bar and webview works fine but when the page is finished loading the progress bar still remains? When I have loaded the page the progress bar visibility doesn't dissapear/change to GONE? Where is the error?
package za.co.test.example;
import android.app.Activity;
import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.KeyEvent;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;
public class KlokTyd extends Activity{
ProgressBar progressBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.klok_tyd);
WebView ourBrow = (WebView) findViewById(R.id.wvBrowser);
progressBar = (ProgressBar) findViewById(R.id.progressBar1);
ourBrow.setWebViewClient(new WebViewClient());
ourBrow.getSettings().setJavaScriptEnabled(true);
ourBrow.loadUrl("http://example.blogspot.com/");
}
public class myWebClient extends WebViewClient
{
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
// TODO Auto-generated method stub
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
progressBar.setVisibility(View.GONE);
}
}
}
You are defining a class that extends WebViewClient but you never use it. Pass an instance of your own class (myWebViewClient) to setWebViewClient(). Change the line
ourBrow.setWebViewClient(new WebViewClient());
to
ourBrow.setWebViewClient(new myWebClient());
I have tried to link a webpage in an android app with webview and set a progress bar, and display the custom error message when page is not available, It works fine but error message is not get displayed, any one help me.
package com.arun.sample;
import android.os.Bundle;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Bitmap;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class Sample extends Activity {
WebView myWebView;
#SuppressLint("SetJavaScriptEnabled")
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_students_login);
myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
myWebView.setWebViewClient(new WebViewClient(){
public void onReceivedError(WebView view,int errorCode ,String description,String failingUrl)
{
myWebView.loadUrl("file:///android_asset/www/error.html");
}
});
myWebView.loadUrl("http://google.co.in");
myWebView.setWebViewClient(new myWebViewClient());
}
private class myWebViewClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
super.onPageStarted(view, url, favicon);
findViewById(R.id.progressBar1).setVisibility(View.VISIBLE);
findViewById(R.id.textView1).setVisibility(View.VISIBLE);
}
#Override
public void onPageFinished(WebView view, String url) {
findViewById(R.id.progressBar1).setVisibility(View.GONE);
findViewById(R.id.textView1).setVisibility(View.GONE);
}
}
}
Your setting webview client twice. Remove the first one.
myWebView.setWebViewClient(new WebViewClient()
and move onReceivedError to myWebViewClient
#Override
public void onReceivedError
i am trying to make a app for android in eclipse. where i different fragments with webviews in it. but i want to show a progress bar when webview in loading but i could not getting it how to do it i checked many tutorials but failed to do so. let me most activity code here.
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.app.Fragment;
import android.annotation.SuppressLint;
//import android.graphics.Bitmap;
//import android.widget.ProgressBar;
//import android.app.ProgressDialog;
//import android.app.Activity;
#SuppressLint("SetJavaScriptEnabled")
public class AdminTab1 extends Fragment {
private WebView webView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
View rootView = inflater.inflate(R.layout.admintab1, container, false);
webView = (WebView) rootView.findViewById(R.id.webView1);
webView.setWebViewClient(new WebViewClient());
webView.setScrollbarFadingEnabled(false);
webView.setHorizontalScrollBarEnabled(false);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setUserAgentString("AndroidWebView");
webView.clearCache(true);
webView.loadUrl("http://ww.google.com");
return rootView;
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.mainmenu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item1:
webView.reload();
break;
case R.id.item2:
webView.goBack();
break;
default:
break;
}
return true;
}
}
You should try this
public class About27Fragment extends Fragment{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View rootView = inflater.inflate(R.layout.about_27, container, false);
final WebView webView = (WebView) rootView.findViewById(R.id.webView_about27);
final ProgressDialog dialog = ProgressDialog.show(getActivity(), "", "Please wait, Loading Page...", true);
webView.getSettings().setJavaScriptEnabled(true);
webView.getSettings().setLoadWithOverviewMode(true);
webView.getSettings().setUseWideViewPort(true);
webView.getSettings().setBuiltInZoomControls(true);
webView.setWebViewClient(new WebViewClient() {
public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon){
dialog.show();
}
#Override
public void onPageFinished(WebView view, String url){
dialog.dismiss();
String webUrl = webView.getUrl();
}
});
webView.loadUrl("https://www.google.com.mx");
return rootView;
}
}
WebViewClient has a lot of callback. You should subclass it and override onPageStarted to show and onPageFinished to dismiss it, for instance. Take a look to the doc, here
private class MyWebClient extends WebViewClient {
#Override
public void onPageStarted(WebView view, String url,
// here show the dialog
}
public void onPageFinished(WebView view, String url) {
// here dismiss it
}
}
and in onCreateView use it like
webView.setWebViewClient(new MyWebClient());
oncreate
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.web_view);
web_view = (WebView) findViewById(R.id.web_view);
pd = new ProgressDialog(Activity.this);
pd.setMessage("Please wait Loading...");
pd.show();
web_view.setWebViewClient(new MyWebViewClient());
web_view.loadUrl("ur site name");
}
WebViewClient
private class MyWebViewClient 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();
}
}
In this way you can implement Progress Dialog in webview.
Try this to get progress in percentage
myWebView.setWebChromeClient(new WebChromeClient() {
public void onProgressChanged(WebView view, int progress) {
// Activities and WebViews measure progress with different
// scales
//Updaate progress bar here with progress int
}
});
The idea is when there is no internet connection available, show my custom dialog to users which indicates there is no connection. Otherwise, when page is loading in WebView, show a ProgressDialog to show that page is loading and dismiss when loading is done. When there is an internet connection this code works, but if there is no, it crashes and I can't find where the error is.

break;
case 2:

connDialog.setContentView(R.layout.connection);
connDialog.setTitle("No Internet Connection");
Button closeButton = (Button) findViewById(R.id.closeButton);
closeButton.setOnClickListener(new closeButtonOnClickListener());
connDialog.show();
break;
}
return super.onCreateDialog(id);
}
private class closeButtonOnClickListener implements OnClickListener
{
public void onClick(View v) {
connDialog.dismiss();
};
}
private class HelloWebViewClient extends WebViewClient {
#Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
#Override
public void onPageStarted(WebView view, String url, Bitmap favicon) {
// TODO Auto-generated method stub
super.onPageStarted(view, url, favicon);
ConnectivityManager conStatus = (ConnectivityManager) view.getContext().getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);
if(conStatus.getActiveNetworkInfo().isConnected() && conStatus.getActiveNetworkInfo() != null)
showDialog(1);
else
showDialog(2);
}
#Override
public void onPageFinished(WebView view, String url) {
// TODO Auto-generated method stub
super.onPageFinished(view, url);
dialog.dismiss();
}
}
}
And this is the error log as well :
When you post error messages, you should tell us which line of the source corresponds.
By pasting your code into a text editor, I believe line 83 is:
if(conStatus.getActiveNetworkInfo().isConnected() && conStatus.getActiveNetworkInfo() != null)
This strongly suggests that conStatus is null and you are trying to call a method of non-existent object.
You should check that it's non-null first.
