Webview in android suddenly stops when button is pressed -

    package com.example.karla;  import android.annotation.suppresslint; import android.app.activity; import android.graphics.bitmap; import android.os.bundle; import android.webkit.webview; import android.webkit.webviewclient;   public class webviewactivity extends activity {  private webview webview;  @suppresslint("setjavascriptenabled") public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.webview);      webview.setwebviewclient(new mywebclient());      webview = (webview) findviewbyid(r.id.webview1);     webview.getsettings().setjavascriptenabled(true);     webview.loadurl("http://www.google.com");   } 

}
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;      } 

}

package com.example.karla;  import android.app.activity; import android.content.context; import android.content.intent; import android.os.bundle; import android.view.view; import android.view.view.onclicklistener;    import android.widget.button;  public class mainactivity extends activity {  private button button;  public void oncreate(bundle savedinstancestate) {     final context context = this;      super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      button = (button) findviewbyid(r.id.buttonurl);      button.setonclicklistener(new onclicklistener() {        @override       public void onclick(view arg0) {         intent intent = new intent(context, webviewactivity.class);         startactivity(intent);       }      });  } 

}

my android application stops when press button. want website load in webview not in browser override urlloading. dont know do? should do?

    @override     public boolean shouldoverrideurlloading(webview view, string url) {         // todo auto-generated method stub          view.loadurl(url);         return true;      } 

if want let webview load page, don't view.loadurl(): return false.

    @override     public boolean shouldoverrideurlloading(webview view, string url) {         return false;      } 

returning true prevent webview loading url means should instead. example, instead of navigating "help" page, show screen inside app help.
