hii i want to open alert if internet is not available and also check if response getting time out..how is it posible??? help me..here is my code of asynctask which is new GetVideoUrlAsyn().execute(); method..
Check network connectivity before executing AsyncTask,
if(isNetworkAvailable(this))
{
new GetVideoUrlAsyn().execute();
}
and this is the method definition,
public boolean isNetworkAvailable(Context ctx)
{
ConnectivityManager cm = (ConnectivityManager)ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnectedOrConnecting()&& cm.getActiveNetworkInfo().isAvailable()&& cm.getActiveNetworkInfo().isConnected())
{
return true;
}
else
{
return false;
}
}
do something like this inside your method callhttppost_numvaluepair(URL, nameValuePairs) of WebServiceCall class,
HttpParams basicparams = new BasicHttpParams();
URI uri = new URI(url);
HttpPost method = new HttpPost(uri);
int timeoutConnection = 60000;//set your timeout period
HttpConnectionParams.setConnectionTimeout(basicparams,
timeoutConnection);
DefaultHttpClient client = new DefaultHttpClient(basicparams);
//and then rest of your code
Note:
Don't forget to put the permission in manifest file,
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
You should use a broadcast receiver as mentioned in other SO answers, but since you have asked how to do this otherwise, here you go:
* Checks for an existing network connectivity
*
* #param context
* The {#link Context} which is needed to tap
* {#link Context#CONNECTIVITY_SERVICE}
* #return True if network connection is available
*/
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connectivity = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
return false;
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}
Will need additional permission to be specified in the manifest file
check internet before execute asyncTask
if(checkNetwork)
{
new GetVideoUrlAsyn().execute();
}
else
{
// do stuff
}
if(CheckNetwork){
new GetVideoUrlAsyn().execute();
}else{
// Check internet connection
}
and
private boolean CheckNetwork() {
ConnectivityManager conMgr = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
if (conMgr.getActiveNetworkInfo() != null
&& conMgr.getActiveNetworkInfo().isAvailable()
&& conMgr.getActiveNetworkInfo().isConnected()) {
return true;
} else {
return false;
}
}

I know that there is a lot of questions about this, but I'm desperated...
I'm trying to show a Dialog while doing an AsyncTask, that must be easy but I'm no able to do it...
I had tried with .execute() and .get() and I had put a for to make the task take a long time, but nothing..

Where is the mistake?
I know there are many questions that have been asked regarding this and i have been going through all that from couple of days but could'nt find a reasonable answer. i am newbie to android and php so i have no idea how things get done.
so basically first i want to know how to run gps as a service in background like when the application is installed it starts and periodically send the coordinates to web server?
Just create a service that runs in the background all the time.
For Example:-
AndroidLocationServices
public class AndroidLocationServices extends Service {
WakeLock wakeLock;
private LocationManager locationManager;
public AndroidLocationServices() {
// TODO Auto-generated constructor stub
}
#Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
#Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
PowerManager pm = (PowerManager) getSystemService(this.POWER_SERVICE);
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "DoNotSleep");
// Toast.makeText(getApplicationContext(), "Service Created",
// Toast.LENGTH_SHORT).show();
Log.e("Google", "Service Created");
}
#Override
#Deprecated
public void onStart(Intent intent, int startId) {
// TODO Auto-generated method stub
super.onStart(intent, startId);
Log.e("Google", "Service Started");
locationManager = (LocationManager) getApplicationContext()
.getSystemService(Context.LOCATION_SERVICE);
locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER,
5000, 5, listener);
}
private LocationListener listener = new LocationListener() {
#Override
public void onLocationChanged(Location location) {
// TODO Auto-generated method stub
Log.e("Google", "Location Changed");
if (location == null)
return;
if (isConnectingToInternet(getApplicationContext())) {
JSONArray jsonArray = new JSONArray();
JSONObject jsonObject = new JSONObject();
try {
Log.e("latitude", location.getLatitude() + "");
Log.e("longitude", location.getLongitude() + "");
jsonObject.put("latitude", location.getLatitude());
jsonObject.put("longitude", location.getLongitude());
jsonArray.put(jsonObject);
Log.e("request", jsonArray.toString());
new LocationWebService().execute(new String[] {
Constants.TRACK_URL, jsonArray.toString() });
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
#Override
public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub
}
};
#Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
wakeLock.release();
}
public static boolean isConnectingToInternet(Context _context) {
ConnectivityManager connectivity = (ConnectivityManager) _context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null) {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null)
for (int i = 0; i < info.length; i++)
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
return false;
}
}
LocationWebService
public class LocationWebService extends AsyncTask<String, String, Boolean> {
public LocationWebService() {
// TODO Auto-generated constructor stub
}
#Override
protected Boolean doInBackground(String... arg0) {
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("location", arg0[1]));
HttpClient httpclient = new DefaultHttpClient();
HttpPost httppost = new HttpPost(arg0[0]);
HttpParams httpParameters = new BasicHttpParams();
httpclient = new DefaultHttpClient(httpParameters);
try {
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response;
response = httpclient.execute(httppost);
StatusLine statusLine = response.getStatusLine();
if (statusLine.getStatusCode() == HttpStatus.SC_OK) {
Log.e("Google", "Server Responded OK");
} else {
response.getEntity().getContent().close();
throw new IOException(statusLine.getReasonPhrase());

Please Help Me How can fix this issue
Thanks In Advance
I have the following code, and what I'm trying to do is to programmatically check if there is an internet connection or not.
Since I'm getting a NetworkOnMainThreadException, and have been advised to use AsyncTask.
I want to perform network operation on hasActiveInternetConnection(Context context)and return true if connected to a network, else false .
How do I do this using AsyncTask?
public class NetworkUtil extends AsyncTask<String, Void, String>{
Context context;
public NetworkUtil(Context context){
this.context = context;
}
private ProgressDialog dialog;
#Override
protected void onPreExecute() {
super.onPreExecute();
}
#Override
protected String doInBackground(String... arg0) {
if (new CheckNetwork(context).isNetworkAvailable())
{
try {
HttpURLConnection urlc = (HttpURLConnection) (new URL("http://www.google.com").openConnection());
urlc.setRequestProperty("User-Agent", "Test");
urlc.setRequestProperty("Connection", "close");
urlc.setConnectTimeout(1500);
urlc.connect();
boolean url= (urlc.getResponseCode() == 200);
String str = String.valueOf(url);
return str;
} catch (IOException e) {
}
}
// your get/post related code..like HttpPost = new HttpPost(url);
else {
Toast.makeText(context, "no internet!", Toast.LENGTH_SHORT).show();
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (dialog.isShowing()) {
dialog.dismiss();
}
}
}
use this class for checking internet connectivity...
public class CheckNetwork {
private Context context;
public CheckNetwork(Context context) {
this.context = context;
}
public boolean isNetworkAvailable() {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager
.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}
}
then.....
use the this ASynTask for httppost.
public class NetworkUtil extends AsyncTask<String, Void, String> {
private ProgressDialog dialog;
#Override
protected void onPreExecute() {
dialog = new ProgressDialog(YourActivity.this);
dialog.setMessage("Loading...");
dialog.setCancelable(false);
dialog.show();
super.onPreExecute();
}
#Override
protected String doInBackground(String... arg0) {
if (new CheckNetwork(YourActivity.this).isNetworkAvailable()) {
// your get/post related code..like HttpPost = new HttpPost(url);
} else {
// No Internet
// Toast.makeText(YourActivity.this, "no internet!", Toast.LENGTH_SHORT).show();
}
return null;
}
#Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
if (dialog.isShowing()) {
dialog.dismiss();
}
}
There is no way to get an Internet connexion state, you will always have the network connection state.
But I found a pretty nice answer here: you send a request to google.com !! :) you can also try to ping to google by unix commandes if you want !!
here the guy is using a thread , and waiting a little bit for the answer, then returning a boolean . you do your staff in the handler . this is his code :
public static void isNetworkAvailable(final Handler handler, final int timeout) {
// ask fo message '0' (not connected) or '1' (connected) on 'handler'
// the answer must be send before before within the 'timeout' (in milliseconds)
new Thread() {
private boolean responded = false;
#Override
public void run() {
// set 'responded' to TRUE if is able to connect with google mobile (responds fast)
new Thread() {
#Override
public void run() {
HttpGet requestForTest = new HttpGet("http://m.google.com");
try {
new DefaultHttpClient().execute(requestForTest); // can last...
responded = true;
}
catch (Exception e) {
}
}
}.start();
try {
int waited = 0;
while(!responded && (waited < timeout)) {
sleep(100);
if(!responded ) {
waited += 100;
}
}
}
catch(InterruptedException e) {} // do nothing
finally {
if (!responded) { handler.sendEmptyMessage(0); }
else { handler.sendEmptyMessage(1); }
}
}
}.start();
}
Then, I define the handler:
Handler h = new Handler() {
#Override
public void handleMessage(Message msg) {
if (msg.what != 1) { // code if not connected
} else { // code if connected
}
}
};
...and launch the test:
isNetworkAvailable(h,2000); // get the answser within 2000 ms
Your AsyncTask should look like this:
private class NetworkUtilTask extends AsyncTask<Void, Void, Boolean>{
Context context;
public NetworkUtilTask(Context context){
this.context = context;
}
protected Boolean doInBackground(Void... params) {
return hasActiveInternetConnection(this.context);
}
protected void onPostExecute(Boolean hasActiveConnection) {
Log.d(LOG_TAG,"Success=" + hasActiveConnection);
}
}
You would then execute it like the following:
NetworkUtilTask netTask = new NetworkUtilTask(context);
netTask.execute();
