the code for the broadcast receiver is
public class MyBroadcastreceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
Intent startServiceIntent = new Intent(context, MyService.class);
startServiceIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startService(startServiceIntent);
}
}
the code for the service is
public class MyService extends Service {
String tag="TestService";
@Override
public void onCreate() {
Toast.makeText(this, "Service created...", Toast.LENGTH_LONG).show();
// Log.i(tag, "Service created...");
}
@Override
public void onStart(Intent intent, int startId) {
super.onStart(intent, startId);
Intent dialogIntent = new Intent(getBaseContext(), LocationStat.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
getApplication().startActivity(dialogIntent);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Toast.makeText(this,"task perform in service",Toast.LENGTH_LONG).show();
/* startActivity(new Intent(MyService.this,LocationStat.class));*/
return super.onStartCommand(intent, flags, startId);
}
@Override
public void onDestroy() {
super.onDestroy();
Toast.makeText(this, "Service destroyed...", Toast.LENGTH_LONG).show();
}
@Override
public IBinder onBind(Intent intent) {
return null;
}
}
and the activity that i am trying to start from the service is
public class LocationStat extends Activity {
double logi;
double lat;
long MINIMUM_DISTANCE_CHANGE_FOR_UPDATES = 1; // in Meters
long MINIMUM_TIME_BETWEEN_UPDATES = 1000; // in Millisecon
Location loc;
LocationManager manager;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
manager=(LocationManager)getSystemService(Context.LOCATION_SERVICE);
manager.requestLocationUpdates(
LocationManager.GPS_PROVIDER,
MINIMUM_TIME_BETWEEN_UPDATES,
MINIMUM_DISTANCE_CHANGE_FOR_UPDATES,
new MyLocationListener()
);
Toast.makeText(this,"activity created...",Toast.LENGTH_LONG).show();
loc=manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
String s;
if(loc!=null)
{
logi=loc.getLongitude();
lat=loc.getLatitude();
s="Lat:" + lat + "\nLong:" + logi;
}
else
{
s ="no location found";
}
Toast.makeText(LocationStat.this,"Your Current Position is:\n" +
s,Toast.LENGTH_LONG).show();
webcall(logi,lat);
//getLoc();
}
public void webcall(double logi,double lat)
{
InputStream is=null;
String result = "";
//the year data to send
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("logitude",Double.toString(logi)));
nameValuePairs.add(new BasicNameValuePair("latitude",Double.toString(lat)));
//http post
try{
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost("http://10.0.2.2/location.php");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity = response.getEntity();
is = entity.getContent();
}catch(Exception e){
Toast.makeText(LocationStat.this,"Error in http connection "+e.toString(),Toast.LENGTH_LONG).show();
}
//convert response to string
try{
BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8);
StringBuilder sb = new StringBuilder();
String line = null;
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result=sb.toString();
Toast.makeText(LocationStat.this,result,Toast.LENGTH_LONG).show();
}catch(Exception e){
Toast.makeText(LocationStat.this,"Error converting result "+e.toString(),Toast.LENGTH_LONG).show();
}
the manifest look like this
<service android:enabled="true" android:name=".MyService">
<intent-filter >
<action android:name="com.android.trace.MyService"/>
</intent-filter>
</service>
<receiver android:name="com.android.trace.MyBroadcastReceiver">

use com.android.trace.MyBroadcastreceiver instead of com.android.trace.MyBroadcastReceiver in manifast.xml for Registering Broadcast Receiver.
