    <p>i am testing my bootcomplete.java to get GPS coordinate (lat,long), when my system reboot, the message is sent out, but latitude and longitude showing 0.0.</p> <p>Is there anything wrong with my BootComplete.java or GPSTracker.java class ? i will post the code below.</p> <p><strong>BootComplete.java</strong></p> <pre><code>public class BootComplete extends BroadcastReceiver{ //private static final String PREFS_NAME = null; public static final String PREFS_NAME = "MyPrefs"; String storedSimSerial; String currentSimSerial; String email; //email address input by user, generate email and sent to this address String mobileno; //mobile number input by user, generate SMS and send to this address String sms; //generate sms to user GPSTracker gps; @Override public void onReceive(Context context, Intent intent) { SharedPreferences prefs = context.getSharedPreferences(PREFS_NAME, 0); storedSimSerial = prefs.getString("storedSimSerial", ""); mobileno = prefs.getString("trustedNum", ""); email = prefs.getString("Email", ""); TelephonyManager tm = (TelephonyManager) context.getSystemService(Service.TELEPHONY_SERVICE); currentSimSerial = tm.getSimSerialNumber(); if(currentSimSerial != null){ if(currentSimSerial.compareToIgnoreCase(storedSimSerial) == 0){ }else{ prefs = context.getApplicationContext().getSharedPreferences(PREFS_NAME, 0); SharedPreferences.Editor editor = prefs.edit(); gps=new GPSTracker(BootComplete.this); gps.getLatitude(); sms = "Alert!!!\nSim card changed.\nSim Serial Number:\n"+tm.getSimSerialNumber()+ "\nNetwork : "+ tm.getNetworkOperatorName()+"\nLatitude:\n" + gps.getLatitude();

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.
