package update.app.jdog1218.com.messingaround;  import android.app.activity; import android.app.dialogfragment; import android.content.intent; import android.os.bundle; import android.view.menu; import android.view.menuitem; import android.view.view; import android.widget.arrayadapter; import android.widget.button; import android.widget.listadapter; import android.widget.listview; import android.widget.relativelayout; import android.widget.textview; import android.widget.toast; import java.net.url; import java.net.urlconnection;  public class mainactivity extends activity {  private button answer_button;  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     relativelayout bible = new relativelayout(this);    }  @override public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.menu_main, menu);       return true; }  @override public boolean onoptionsitemselected(menuitem item) {     // handle action bar item clicks here. action bar     // automatically handle clicks on home/up button, long     // specify parent activity in androidmanifest.xml.       return super.onoptionsitemselected(item); }  public void gotoinbeddedbible(menuitem item) {     intent bibleclass = new intent(this, bible.class);      final int result = 1;      bibleclass.putextra("callingactivity", "mainactivity");      startactivity(bibleclass);     startactivityforresult(bibleclass, result);  }  @override protected void onactivityresult(int requestcode, int resultcode, intent data) {     super.onactivityresult(requestcode, resultcode, data);  }  public void exit(menuitem item) {     button exitprocess = (button) findviewbyid(r.id.submit);     android.os.process.killprocess(android.os.process.mypid());     system.exit(1); }  public void sotd(menuitem item) {     intent clickedsotd = new intent(this, sotd.class);      int result = 1;      startactivity(clickedsotd);  } }

package update.app.jdog1218.com.messingaround;   import android.app.activity;  import android.content.intent;  import android.os.asynctask;  import android.os.bundle;  import android.os.persistablebundle;  import android.view.menu;  import android.widget.textview;   import org.jsoup.jsoup;  import org.jsoup.connection;  import org.jsoup.nodes.document;  import org.jsoup.nodes.element;  import org.jsoup.select.elements;  import org.w3c.dom.node;  import org.w3c.dom.text;   import java.io.ioexception;   import static org.jsoup.jsoup.*;  /*  * created joel on 5/28/2015.  */  public class sotd extends activity {   @override protected void onstart() {     super.onstart(); } string title;  @override public void oncreate(bundle savedinstancestate, persistablebundle persistentstate) {     super.oncreate(savedinstancestate, persistentstate);     setcontentview(r.layout.sotd);     intent activitythatcalled = getintent();  }  @override public boolean oncreateoptionsmenu(menu menu) {     return super.oncreateoptionsmenu(menu); }  /**  * pull , parse html of compass hb sotd.  *  * @return documentstring  * @throws ioexception  */ protected string pullhtml() {     super.onstart();     final string url = "https://www.compasshb.com/api/v1/passages";     document doc = null;     textview textview = (textview) findviewbyid(r.id.sotd);     try {         doc = jsoup.connect(url).get();         textview.settext(doc.owntext());         string paragraph = doc.title();           return paragraph;     } catch (ioexception e) {         e.printstacktrace();     }      return null;  }  @override protected void onpostresume() {     super.onpostresume(); } }
