I am currently developing for android using eclipse I recently ran into an issue where my app no longer launches, and it just crashes when it is opened. I think that the issue may lay in the layout file, or the <code>activity_main</code> file. MainActivity class: <pre><code>package com.dd.splash; import com.google.android.gms.maps.*; import com.google.android.gms.maps.model.*; import java.io.IOException; import java.util.List; import java.util.Locale; import android.app.Activity; import android.app.AlertDialog; import android.content.ContentResolver; import android.content.Context; import android.content.DialogInterface; import android.content.Intent; import android.content.pm.ActivityInfo; import android.location.Address; import android.location.Geocoder; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.provider.Settings; import android.util.Log; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.ProgressBar; import android.widget.Toast; public class myMainScreen extends Activity implements OnClickListener { private LocationManager locationMangaer=null; private LocationListener locationListener=null; private Button btnGetLocation = null; private EditText editLocation = null; private ProgressBar pb =null; private static final String TAG = "Debug"; private Boolean flag = false; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); //if you want to lock screen for always Portrait mode setRequestedOrientation(ActivityInfo .SCREEN_ORIENTATION_PORTRAIT); pb = (ProgressBar) findViewById(R.id.progressBar1); pb.setVisibility(View.INVISIBLE); //This part editLocation = (EditText) findViewById(R.id.editTextLocation); btnGetLocation = (Button) findViewById(R.id.btnLocation); btnGetLocation.setOnClickListener(this); locationMangaer = (LocationManager) getSystemService(Context.LOCATION_SERVICE); } @Override public void onClick(View v) { flag = displayGpsStatus(); if (flag) { Log.v(TAG, "onClick"); //setContentView(R.layout.map); editLocation.setText("Please wait while we locate you..."); pb.setVisibility(View.VISIBLE); locationListener = new MyLocationListener(); locationMangaer.requestLocationUpdates(LocationManager .GPS_PROVIDER, 5000, 10,locationListener); } else { alertbox("Gps Status", "Your GPS is: OFF"); } } /*----Method to Check GPS is enable or disable ----- */ private Boolean displayGpsStatus() { ContentResolver contentResolver = getBaseContext() .getContentResolver(); boolean gpsStatus = Settings.Secure .isLocationProviderEnabled(contentResolver, LocationManager.GPS_PROVIDER); if (gpsStatus) { return true; } else { return false; } } /*----------Method to create an AlertBox ------------- */ protected void alertbox(String title, String mymessage) { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setMessage("Your Device's GPS is Disabled!") .setCancelable(false) .setTitle("** Gps Status **") .setPositiveButton("Gps On", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { // finish the current activity // AlertBoxAdvance.this.finish(); Intent myIntent = new Intent( Settings.ACTION_SECURITY_SETTINGS); startActivity(myIntent); dialog.cancel(); } }) .setNegativeButton("Cancel", new DialogInterface.OnClickListener() { public void onClick(DialogInterface dialog, int id) { // cancel the dialog box dialog.cancel(); } }); AlertDialog alert = builder.create(); alert.show(); } /*----------Listener class to get coordinates ------------- */ private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { editLocation.setText(""); pb.setVisibility(View.INVISIBLE); Toast.makeText(getBaseContext(),"Location changed : Lat: " + loc.getLatitude()+ " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); String longitude = "Longitude: " +loc.getLongitude(); Log.v(TAG, longitude); String latitude = "Latitude: " +loc.getLatitude(); Log.v(TAG, latitude); /*----------to get City-Name from coordinates ------------- */ String cityName=null; String countryName=null; String stateName=null; //Bundle extraInfo=null; Geocoder gcd = new Geocoder(getBaseContext(), Locale.getDefault()); List<Address> addresses; try { addresses = gcd.getFromLocation(loc.getLatitude(), loc .getLongitude(), 1); if (addresses.size() > 0) System.out.println(addresses.get(0).getLocality()); cityName=addresses.get(0).getLocality(); countryName=addresses.get(0).getCountryName(); stateName=addresses.get(0).getAdminArea(); //extraInfo=addresses.get(0).getExtras(); } catch (IOException e) { e.printStackTrace(); } //String extraInfoHolder = "(Coming in next update!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
