I want to get the content to be displayed in my android application as soon as it is updated on a particular website.
how can I do that? I'm new to android development....please help
sure use WebView - Android documentation here: http://developer.android.com/reference/android/webkit/WebView.html
You can also consider using PhoneGap and make a hybrid native html5 app.
Hi you can use WebView for this purpose please have alook as the example is given below
res/layout/main.xml –
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/webView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
the WebViewActivity.java is as follows
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebViewActivity extends Activity {
private WebView webView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
webView = (WebView) findViewById(R.id.webView1);
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl("http://www.google.com");
}
}
do not forget to have permission at manifest
<uses-permission android:name="android.permission.INTERNET" />
You can display the web content using these ways,
Through cross platforms, such as PhoneGap with jQuery Mobile or Sencha touch etc,.
Through Android WebView class.
If you try to display a web content using Android WebView class, refer this sample tutorial.

I try to load youtube website using WebView in Android application. Need to load whole youtube site to WebView (not only one certain video url). It means user select video on youtube site and then play. But the playing of video is jammming. Is it wrong way using youtube inside application ?
I am using this code: webView.loadUrl(url);
pls Follow this code it will work for you
MainActivity.java
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.webkit.WebView;
public class MainActivity extends AppCompatActivity {
private WebView mWebview ;
private String youtubeUrl = "https://www.youtube.com/";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebview = (WebView) findViewById(R.id.youtubeWebView);
mWebview.loadUrl(youtubeUrl);
mWebview.getSettings().setJavaScriptEnabled(true);
}
}
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<WebView
android:id="#+id/youtubeWebView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</android.support.constraint.ConstraintLayout>
and add Internet Permission inside your Manifest file
AndroidManifest.xml
<uses-permission android:name="android.permission.INTERNET" />
it will looks like this in the below pic.
you can load any url into web view and add the internet permission inside your app's manifest file and use like below code --
yourWebView.loadUrl(youtubeUrl);
this works for me , i am sure it will work mate
I am writing an Android App for a charity, and would like to be able to display the charity's facebook feed within the App. I don't want it to go through the phone's web browser, nor the facebook app.
I read on the developers.facebook.com how to add facebook's android sdk to the app's build gradle. But what I can't find is code for a simple android activity that will display the facebook timeline. I don't have time to dive deep into facebook's sdk to fiigure it out. And the last thing I want to do is reinvent the wheel.
Can anyone point me towards some code for a simple activity to display a facebook timeline? Any help will be greatly appreciated.
I'm not home so I can't test this right now but it should work.
In your layout file, put a webview like so:
<WebView
android:id="#+id/mWebView"
android:layout_width="match_parent"
android:layout_height="match_parent" />
Then in the onCreate method:
WebView mWebView = (WebView) findViewById(R.id.mWebView);
WebSettings webSettings = mWebView.getSettings();
webSettings.setJavaScriptEnabled(true);
mWebView.loadUrl("http://LinkToFacebookPage.com/");
And finally, in your manifest file put the following permission before < Application >
<uses-permission android:name="android.permission.INTERNET" />
So I have a website with mobile version. I am trying to do an App for it.
This is my activity_main.xml file
<?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"
android:scrollbars="none"/>
and this is my MainActivity.java class
package com.example.esouqbh.esouq;
import android.app.Activity;
import android.os.Bundle;
import android.view.Window;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import com.example.esouqbh.esouq.R;
public class MainActivity extends Activity
{#Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//Remove title bar as we already have it in the web app
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
//Point to the content view defined in XML
setContentView(R.layout.activity_main);
//Configure the webview setup in the xml layout
WebView myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings = myWebView.getSettings();
//Yes, we want javascript, pls.
webSettings.setJavaScriptEnabled(true);
//Make sure links in the webview is handled by the webview and not sent to a full browser
myWebView.setWebViewClient(new WebViewClient());
//And let the fun begin
myWebView.loadUrl("http://esouqbh.com"); }}
for some reason when I run the app it says on my phone (Im running the APP on my phone as an emulator)
I get this error
Web page not available
The web page at http://esouqbh.com could not be loaded as:
net::ERR_CACHE_MISS
note that my website functions perfectly with no problem if I open it from my computer browser or phone.
EDIT:: Found solution by adding
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
in androidmanifest.xml!
NO, it´s not a folder, by adding :
<uses-permission android:name="android.permission.INTERNET"></uses-permission>
into you AndroidManifest.xml means that your application will load the page from the internet into your WebView
INTERNET permission: allows applications to open network sockets.
I have an Android webView which loads a remote web page. As the code of this page is controlled by a colleague I can ask him to change it but I would prefer to find a solotion totally on client side.
For reasons regarding traffic and performance we want to store our css and javascript files locally on the client and not load them from the server.
What I came up with are two ideas but none of them worked out so far.
Store all the files in the asset folder and have the html refer to them
Problem: The webview seems to be not allowed to access "file:///..." urls
Question: Is there a way to work around this issue?
Just ignore all those references in the html and just inject all those files after loading them in the webview
Question: Just how do I add those files (.css / .js) to my already loaded html?
You can build a local WebView in the following way
The Activity (LocalWebviewActivity.java)
The Layout (activity_localwebview.xml)
The Assets folder (in the root of "assets" folder, create the folder "css" and place "style.css" in here)
You refer to JS files the same way you refer to CSS StyleSheets
LocalWebviewActivity.java
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class LocalWebviewActivity extends Activity {
WebView myWebView;
StringBuilder mySBcontent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_localwebview);
myWebView = (WebView) findViewById(R.id.webkit);
mySBcontent = new StringBuilder();
mySBcontent.append("<html>");
mySBcontent.append("<head>");
mySBcontent.append("<link type='text/css' rel='stylesheet' href='css/style.css'>");
mySBcontent.append("</head>");
mySBcontent.append("<body>");
mySBcontent.append("<h1>My Heading</h1>");
mySBcontent.append("<p>My HTML content</p>");
mySBcontent.append("<p><img style='width:150px;' src='myImg.png' /></p>");
mySBcontent.append("</body>");
mySBcontent.append("</html>");
myWebView.loadDataWithBaseURL("file:///android_asset/", mySBcontent.toString(), "text/html", "UTF-8", "");
}
}
activity_localwebview.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<WebView
android:id="#+id/webkit"
android:layout_width="fill_parent"
android:layout_height="fill_parent"/>
</LinearLayout>
I am looking for a way to load an external website within a page in the app.
For example have a website link for a company on the main screen and when clicked have the transition effect to another page that displays the company website, but also allows you to include the header and footer for the page. You can also include options to go back, or other links.
I believe this is possible, so any help with this would be great. Thanks,
I believe you are talking about Android's WebView class.
http://developer.android.com/reference/android/webkit/WebView.html
A View that displays web pages. This class is the basis upon which you can roll your own web browser or simply display some online content within your Activity. It uses the WebKit rendering engine to display web pages and includes methods to navigate forward and backward through a history, zoom in and out, perform text searches and more.
http://developer.android.com/resources/tutorials/views/hello-webview.html
You just need to use the webview view. After that it's pretty simple to place the view wherever you want and send it to any url you'd like.
WebView mWebView;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("http://www.google.com");
}
I currently am using this method and it works.
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class ThirdActivity extends Activity
{
WebView webview;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.html_view);
webview = (WebView)findViewById(R.id.viewHTML);
webview.getSettings().setJavaScriptEnabled(true);
webview.setWebViewClient(new WebViewClient());
webview.loadUrl("https://twitter.com/LaserPros");
}
}
don't forget your xml file mine is named html_view it has a webview in it with the id of viewHTML the file looks like this:
<?xml version="1.0" encoding="utf-8"?>
<WebView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/viewHTML"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
in the class activity the important thing to (and what most people miss when giving an answer) is to set your web view as the WebClient otherwise your phone will want to open the url in a external browser.
