[Q] WebView app opens up default browser.

Hello I am a Android newbie and I am currently learning how to code applications using Eclipse so I made one yesterday using webview on eclipse but everytime I open the app it takes me to the website but on my default browser. I want the website to open up in the app not on my browser. Anyone know how to fix this?

You need to read the WebView Reference on Android.
Apparently you open the website on a Intent, so the website is opened on the default browser.
Instead, you need to make you Activity act as a WebView on the 'onCreate()' :
Code:
WebView webview = new WebView(this);
setContentView(webview);
And then open the website :
Code:
// Simplest usage: note that an exception will NOT be thrown
// if there is an error loading this page (see below).
webview.loadUrl("my_url");
// OR, you can also load from an HTML string:
String summary = "<html><body>You scored <b>192</b> points.</body></html>";
webview.loadData(summary, "text/html", null);
// ... although note that there are restrictions on what this HTML can do.
// See the JavaDocs for loadData() and loadDataWithBaseURL() for more info.

Um this is my MainActivity.java
package com.graaltailor.JFA;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.webkit.WebView;
public class MainActivity extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("examplewebsite");
}
}

You need to do something like this to overwrite urlredirect opened in the default browser :
Code:
package com.graaltailor.JFA;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.webkit.WebView;
public class MainActivity extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("examplewebsite");
}
mWebView.setWebViewClient(new WebViewClient() {
public boolean shouldOverrideUrlLoading(WebView view, String url){
// do your handling codes here, which url is the requested url
// probably you need to open that url rather than redirect:
view.loadUrl(url);
return false; // then it is not handled by default action
}
});
}

I replaced the code with the one you replied with and I get a bunch of errors.

sorry I made a mistake in the code
Code:
package com.graaltailor.JFA;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.webkit.WebView;
public class MainActivity extends Activity {
WebView mWebView;
/** Called when the activity is first created. */
@override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.loadUrl("examplewebsite");
mWebView.setWebViewClient(new WebViewClient() {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url){
// do your handling codes here, which url is the requested url
// probably you need to open that url rather than redirect:
view.loadUrl(url);
return false; // then it is not handled by default action
}
});
}
}
