I will explain the process of my app...
First it is showing google maps then I'm drawing some polylines and then I'm choosing some contact to send him coordinates(all of that was in main activity and it's working)
That's the code from my main activity:
public class MainActivity extends FragmentActivity {
static boolean active = false;
@Override
public void onStart() {
super.onStart();
active = true;
}
@Override
public void onStop() {
super.onStop();
active = false;
}
public static boolean isActive(){
return active;
}
private static final int PICK_CONTACT = 1;
GoogleMap googleMap;
ArrayList<LatLng> points= new ArrayList<LatLng>() ;
Double glat;
Double glon;
int find_someone=0;
int save=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Getting reference to the SupportMapFragment of activity_main.xml
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
// Getting GoogleMap object from the fragment
googleMap = fm.getMap();
// Enabling MyLocation Layer of Google Map
googleMap.setMyLocationEnabled(true);
// Enabling buildings of Google Map
googleMap.setBuildingsEnabled(true);
googleMap.setOnMapLoadedCallback(new OnMapLoadedCallback() {
@Override
public void onMapLoaded() {
Location lm = googleMap.getMyLocation();
if (lm!=null){
CameraPosition cp = new CameraPosition.Builder()
.target(new LatLng(lm.getLatitude(), lm.getLongitude()))
.zoom(17)
.build();
googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cp));
}
}
});
// Setting OnClick event listener for the Google Map
googleMap.setOnMapClickListener(new OnMapClickListener() {
@Override
public void onMapClick(LatLng point) {
// Instantiating the class MarkerOptions to plot marker on the map
MarkerOptions markerOptions = new MarkerOptions();
// Setting latitude and longitude of the marker position
markerOptions.position(point);
// Setting title of the infowindow of the marker
markerOptions.title("Position");
// Setting the content of the infowindow of the marker
markerOptions.snippet("Latitude:"+point.latitude+","+"Longitude:"+point.longitude);
// Instantiating the class PolylineOptions to plot polyline in the map
PolylineOptions polylineOptions = new PolylineOptions();
// Setting the color of the polyline
polylineOptions.color(Color.BLUE);
// Setting the width of the polyline
polylineOptions.width(6);
// Adding the taped point to the ArrayList
points.add(point);
// Setting points of polyline
polylineOptions.addAll(points);
// Adding the polyline to the map
googleMap.addPolyline(polylineOptions);
// Adding the marker to the map
googleMap.addMarker(markerOptions);
}
});
googleMap.setOnMapLongClickListener(new OnMapLongClickListener() {
@Override
public void onMapLongClick(LatLng point) {
// Clearing the markers and polylines in the google map
googleMap.clear();
// Empty the array list
points.clear();
}
});
if (String.valueOf(points)!=null){
Button pickContact = (Button) findViewById(R.id.button1);
pickContact.setOnClickListener(new OnClickListener(){
public void onClick(View v) {
save=1;
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE);
startActivityForResult(intent, 1);
}
});
}
else{
Toast.makeText(this, "select points", Toast.LENGTH_LONG).show();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (data != null) {
Uri uri = data.getData();
if (uri != null) {
Cursor c = null;
try {
c = getContentResolver().query(uri, new String[]{
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.TYPE },
null, null, null);
if (c != null && c.moveToFirst()) {
String number = c.getString(0);
int type = c.getInt(1);
showSelectedNumber(type, number);
System.out.println(number);
System.out.println("val: "+String.valueOf(points));
if (save==1)
{
SmsManager sm = SmsManager.getDefault();
ArrayList<String> parts =sm.divideMessage(String.valueOf(points));
int numParts = parts.size();
ArrayList<PendingIntent> sentIntents = new ArrayList<PendingIntent>();
ArrayList<PendingIntent> deliveryIntents = new ArrayList<PendingIntent>();
for (int i = 0; i < numParts; i++) {
sentIntents.add(PendingIntent.getBroadcast(getBaseContext(), 0, getIntent(), 0));
deliveryIntents.add(PendingIntent.getBroadcast(getBaseContext(), 0, data, 0));
}
sm.sendMultipartTextMessage(number,null, parts, sentIntents, deliveryIntents);
}
}
}
finally {
if (c != null) {
c.close();
}
}
}
}
}
public void showSelectedNumber(int type, String number) {
Toast.makeText(this, type + ": " + number, Toast.LENGTH_LONG).show();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
Inflate the menu; this adds items to the action bar if it is present.
return true;
}
}
But then I see this logcat comes out running inifine ... it is caused from the service that I'm running

THE NETWORK IN THE LOGCAT COMES FROM THIS SERVICE CODE AT THE END IN A FUNCTION CALLED : public Location getLocation() .... And I'm calling this service from BroadcastReceiver.
Why this service gets stuck on the network message?
