my app is crashing when there is no internet and i want my markers or my map to refresh each second

i made a googlemap app where my markers are displyed.
the problem is when there no internet, the app is crashing. The code under onResume does not solve the problem.
also i want to refresh the map or markers each second on the map.
if you have any ideas please i am here to learn from all of you.
here is my MapActivity code :

this MapActivity is slow to load, could you teach me a way to make it goes faster?
Best regard :)
waiting for your propositions.
PS: i have removed some functions to make the code look short but i kept the most important in is case.

For the crashing issue
create a class
public class NetWorkChecker {
static NetworkInfo wifi, mobile;
public static Boolean check(Context c) {
ConnectivityManager cm = (ConnectivityManager) c.getSystemService(Context.CONNECTIVITY_SERVICE);
try {
wifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
mobile = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
} catch (Exception e) {
e.printStackTrace();
}
if (wifi != null && wifi.isConnected() && wifi.isAvailable()) {
return true;
} else if (mobile != null && mobile.isAvailable() && mobile.isConnected()) {
return true;
} else {
//Toast.makeText(c, "No Network Connection", Toast.LENGTH_SHORT).show();
// ((Activity) c).finish();
displayMobileDataSettingsDialog(c,"No Network Connection","No Network Connection");
return false;
}
}
public static AlertDialog displayMobileDataSettingsDialog(final Context context, String title, String message) {
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle(title);
builder.setMessage(message);
builder.setCancelable(false);
builder.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(Settings.ACTION_DATA_ROAMING_SETTINGS);
context.startActivity(intent);
}
});
builder.show();
return builder.create();
}
}
to check if the devise have an active internet connection
call
if (!NetWorkChecker.check(this)){
////do your refres

How to call inbuilt method of location listener in another class

I am using location listener to track the location.I implement the location listener, there are inbuilt methods of location listener such as onLocationChanged,OnstatusChanged,onProviderEnabled etc.Whenerver the location changed it will hit on server but I want to do at every 10 min of interval So I am using timer for that after every 10 mins it will hit the location. I cannot call the method inside the timer. So how to do it.

Custom Icon on Android Google maps not loading

Ill try my best to explain.
I have a page on my android app that is a google map that has stores locations on it.
Depending on the type of store, it has a custom icon. The link for the custom icon I retrieved trough MySQL.
The problem I am having is when I open the page instead of showing me the custom icons for the stores it shows me the default icon. But when I go to another page on the app and go back to the maps page it loads all the custom icons. It seems to me that on the first page launch it does not replace the default icon.
Since im new to programming ive added the whole page because I might be missing something. I think that the reason this is happening is due to the method "parseData()"
Thank you,

Check this documentation on how to customize the marker image.
You can replace the default marker image with a custom marker image, often called an icon. Custom icons are always set as a BitmapDescriptor, and defined using one of the methods in the BitmapDescriptorFactory class.
Here is a sample code on how to create a marker with a custom icon.
private static final LatLng MELBOURNE = new LatLng(-37.813, 144.962);
private Marker melbourne = mMap.addMarker(new MarkerOptions()
.position(MELBOURNE)
.title("Melbourne")
.snippet("Population: 4,137,400")
.icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));
NOTE:
getMap() is already deprecated, so use getMapAsync() in your code.

Pass List<> to a Fragment

I'm creating an Android map app by getting venue from Foursquare and using Google Map.
I have set my MainActivity to get the venue results, a MapFragmentClass and a VenueModel.
I keep all the JSON result from Foursquare into a List venueModelList in the MainActivity.
What I want to do is to add markers in the MapFragmentClass based on the coordinates received from Foursquare.
However, I am stuck trying to pass the venueModelList to the MapFragmentClass.
Any help is appreciated. Thanks.

Pass Latitude and Longitude to Google API Places Search in Android

I have literally been searching for this for weeks. I am a novice java programmer but I have been able to piece together an app that can use a double latitude and longitude hard coded in the same class. It will show a list of current places surrounding those points. I have another separate class with a method that is able to get the current location based on the gps/network but I can't pass the variables created from this second class to the PlaceRequest class. I have looked through all of the tutorials on the above subjects but there isn't anything combining current location and place search results. I have two getters declared but can't call the variables in these. Again sort of a rookie so may be an easy fix. Any ideas?
Update - Here is my code so far:
GooglePlaceActivity.java
public class GooglePlaceActivity extends Activity {
/** Called when the activity is first created. */
Button btn1;
TextView txt1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.main);
btn1 = (Button)findViewById(R.id.button1);
txt1 = (TextView)findViewById(R.id.textView1);
btn1.setOnClickListener(l);
}
private class SearchSrv extends AsyncTask<Void, Void, PlacesList>{
#Override
protected PlacesList doInBackground(Void... params) {

}
#Override

if (result!=null){

text = text + place.name +"\n";
}
txt1.setText(text);
}

}

Edit: After looking your complete code, I see a few fundamental design flaws so I'm going to show you how I did it and you can adapt it to your program flow. Please keep in mind that this example is vastly simplified from my original, but it should be enough to get you going.
First, the CurrentLocation.java file. My design decision for wrapping this in a Future was so that I can re-use it in multiple activities with the added bonus of killing it when necessary.
public class CurrentLocation implements Callable<Location> {
private static final String TAG = "CurrentLocation";
private Context context;
private LocationManager lm;
private Criteria criteria;
private Location bestResult;
private boolean locationListenerWorking;
public CurrentLocation(Context context) {
lm = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
this.context = context;
criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
bestResult = null;
locationListenerWorking = false;
}
public Location call() {
return getLoc();
}
private Location getLoc() {
String provider = lm.getBestProvider(criteria, true);
if (provider != null) {
Log.d(TAG, "Using provider: " +provider);
locationListenerWorking = true;
lm.requestLocationUpdates(provider,
0,
0,
singeUpdateListener,
context.getMainLooper());
} else {
Log.w(TAG, "Couldn't find a location provider");
return null;
}
while (locationListenerWorking) {
// Check for the interrupt signal - terminate if necessary
if (Thread.currentThread().isInterrupted()) {
Log.i(TAG, "User initiated interrupt (cancel signal)");
cleanup();
break;
}
try {
// ghetto implementation of a busy wait...
Thread.sleep(500); // Sleep for half a second
} catch (Exception e) {
Log.d(TAG, "Thread interrupted..");
cleanup();
break;
}
}
return bestResult;
}
private void cleanup() {
if (lm != null) {
Log.d(TAG, "Location manager not null - cleaning up");
lm.removeUpdates(singeUpdateListener);
} else {
Log.d(TAG, "Location manager was NULL - no cleanup necessary");
}
}
/**
* This one-off {#link LocationListener} simply listens for a single location
* update before unregistering itself. The one-off location update is
* returned via the {#link LocationListener} specified in {#link
* setChangedLocationListener}.
*/
private LocationListener singeUpdateListener = new LocationListener() {
public void onLocationChanged(Location location) {
Log.d(TAG, "Got a location update");
if (location == null) {
Log.d(TAG, "Seems as if we got a null location");
} else {
bestResult = location;
}
cleanup();
locationListenerWorking = false;
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
}
Then in your calling class (i.e. where you need the lat/lon coordinates - you want to do this from an Activity):
private class GetLocationTask extends AsyncTask <Void, Void, Location> {
private Future<Location> future;
private ExecutorService executor = new ScheduledThreadPoolExecutor(5);
private boolean cancelTriggered = false;
protected void onPreExecute() {
Log.d(TAG, "Starting location get...");
}
public Location doInBackground(Void... arg) {
CurrentLocation currLoc = new CurrentLocation(getApplicationContext());
future = executor.submit(currLoc);
long LOCATION_TIMEOUT = 20000; // ms = 20 sec
try {
// return future.get(Constants.LOCATION_TIMEOUT, TimeUnit.MILLISECONDS);
return future.get(LOCATION_TIMEOUT, TimeUnit.MILLISECONDS);
} catch (Exception e) {
Log.w(TAG, "Location get timed out");
future.cancel(true);
return null;
}
}
public boolean killTask() {
cancelTriggered = true;
boolean futureCancelRes = future.cancel(true);
this.cancel(true);
Log.d(TAG, "Result of cancelling task: " +futureCancelRes);
return futureCancelRes;
}
protected void onPostExecute(Location res) {
if (cancelTriggered) {
Log.d(TAG, "User initiated cancel - this is okay");
cancelTriggered = false;
} else if (res == null) {
Log.d(TAG, "Could not get a location result");
} else {
double lat = res.getLatitude();
double lon = res.getLongitude();
Log.d(TAG, "Latitude: " +lat);
Log.d(TAG, "Longitude: " +lon);
}
}
}
Finally to wrap things up, here's how you call it:
GetLocationTask t = new GetLocationTask();
t.execute();
And if you need to kill the location update for whatever reason (if your user switches out of your activity, etc), this will kill the AsyncTask as well as the associated Future task.
t.killTask();
P.S. You may want to get your API keys changed and edit it out of your post.
