Question

I’m new at Eclipse and the Android applications making so here comes a very rookie question. How can I make this function work properly? I have just copy > paste it to my public class nowActivity extends Activity { and fixed the errors that accord. The function is as follows:

package weather.right;

import weather.right.now.R;
import android.app.Activity;
import android.app.AlertDialog;
import android.content.DialogInterface;
import android.content.Intent;
import android.location.LocationManager;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

public class nowActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE);

        if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
             Toast.makeText(this, "GPS is Enabled in your devide", Toast.LENGTH_SHORT).show();
        }else{
            showGPSDisabledAlertToUser();
        }
    }

    public void goToSo(View view) {
        goToUrl("http://erik-edgren.nu/weather");
    }

    private void goToUrl(String url) {
        Uri uriUrl = Uri.parse(url);
        Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
        startActivity(launchBrowser);
    }

        private void showGPSDisabledAlertToUser(){
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(this);
                alertDialogBuilder.setMessage("GPS is disabled in your device. Would you like to enable it?")
             .setCancelable(false)
             .setPositiveButton("Goto Settings Page To Enable GPS",
                  new DialogInterface.OnClickListener(){
                  public void onClick(DialogInterface dialog, int id){
                          Intent callGPSSettingIntent = new Intent(
                                                android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS);
                                startActivity(callGPSSettingIntent);
                  }
             });
             alertDialogBuilder.setNegativeButton("Cancel",
                  new DialogInterface.OnClickListener(){
                  public void onClick(DialogInterface dialog, int id){
                       dialog.cancel();
                  }
             });
        AlertDialog alert = alertDialogBuilder.create();
        alert.show();
        }
}

Thanks in advance.

protected void onCreate1(Bundle savedInstanceState) should be protected void onCreate(Bundle savedInstanceState)?

You are supposed to override the onCreate() method. See this for more details.

For Android, sub-classes of Activity are supposed to implement certain methods so to do this you have to override certain methods by matching the parent class’ methods exactly. onCreate() is one such method.

For the emulator, GPS can be tested by following the guide here. Otherwise it will show up as disabled.
