Hi mark,
I feel I explained things loosely. Let me get into the specifics. I
have an application which does two things - collects GPS data and
sends to server in the backend and on frontend shows a
website(contains my customized maps). I am trying to get things work
simultaneously and it works fine on emulator but when I tested it on
the real device - samsung galaxy ace; the thing worked. Now, here is
the problem - if I analyze the data, though the application started
the GPS location finder but never sent anything to server. The website
loads once partially and then afterwards the whole application is
hung.
I tried to incorporate threading and Asynctask class but no solution -
gave Application Not Responding(ANR) error. Would like if anyone could
refer to similar examples or suggest a solution.
Code :
=
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//downloading the website
setupWebView();
//getting the GPS coordinates and sending to server
getLocation();
}
private void getLocation() {
LocationManager locationManager =
(LocationManager)getSystemService(Context.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
String provider = locationManager.getBestProvider(criteria,true);
locationManager.requestLocationUpdates(provider, 1, 0, this);
}
private void setupWebView(){
webView = (WebView) findViewById(R.id.webview);
webView.setWebViewClient(new HelloWebViewClient());
webView.getSettings().setJavaScriptEnabled(true);
webView.loadUrl(MAP_URL);
}
=
Thanks.
