Android Maps API Modification

I have a script that displays the current location of the user and when you click somewhere on the map it displays the route to it.
I only need to change this code so that it directly displays the route to a predefined latitude longitude, not just when I click at some point.
This code already automatically picks up my current position.
What should I do?

Error getMap();

I have an error in this line of code (72). I have already done a search in the forum but nothing solved yet, I tried to change to getMapAsync ();
It seems that this function is obsolete but as this code I found on the internet I do not know how to update it.

The problem is that the map instantiation isn't finished when running the onCreate. You have to start your tasks depending on the map when you received the callback that the Map is done loading.

You should try to get map async, something like that:
public class FindLocationActivity extends AppCompatActivity implements
OnMapReadyCallback {
private GoogleMap map;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_find_location);
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap map) {
this.map = map;
//from this moment do whatever you want to do with map
}
}
You are getting error probably becouse map is not ready when you call getMap() and you get null. To prevent it, you shold always get map async, and when it's ready, make some operations on it.

Google Maps Place marker not displaying

}
You may refer this code this will get the relavent places in google map.
Give string input as type like hospital,hotel,policestation,park etc.,
I hope,this may help you.

how to reflect the checkbox.oncheckchanged listener in one activity to another activity in android?

I have a requirement in which I have an activity which contains Checkboxes and the onChangedEvent of Checkbox should get reflected in other activity which is a map fragment. I am not understanding how to do it. Following is my main activity
public class MainActivity extends FragmentActivity implements LocationListener {
GoogleMap mGoogleMap;

String[] mPlaceType=null;

You have to use the same SharedPreferences name in both, in order to write and read to the same table.
Change this line in ListViewPlaces:
sharedPreferences = getSharedPreferences("instantMessaging", MODE_PRIVATE);
To:
sharedPreferences = getSharedPreferences("instantmessagingmap", MODE_PRIVATE);

Android Google Map set country

I am new in developing with android google play sdk.
I want my map have a search function but it only specify on my country.
Let just say i live in Singapore, when i search a location, i want my engine only search on my country. How to set it ??
This is my Java Code
public class NearbyActivity extends FragmentActivity {
Button mBtnFind;
GoogleMap mMap;
EditText etPlace;
LatLng myPosition;
#Override
protected void onCreate(Bundle savedInstanceState) {

mMap = mapFragment.getMap();
// Getting reference to EditText
etPlace = (EditText) findViewById(R.id.et_place);
// Setting click event listener for the find button
mBtnFind.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// Getting the place entered
String location = etPlace.getText().toString();
if(location==null || location.equals("")){
Toast.makeText(getBaseContext(), "No Place is entered", Toast.LENGTH_SHORT).show();
return;
}
String url = "https://maps.googleapis.com/maps/api/geocode/json?";
try {

}
String address = "address=" + location;
String sensor = "sensor=false";

place.put("formatted_address", formatted_address);
place.put("lat", lat);

} catch (JSONException e) {
e.printStackTrace();
}
return place;
}
}

You can set a bias for your query to prefer one region. Note that this will only prefer the specific region without excluding all other ones.
Based on your query you will have something like this:
https://maps.googleapis.com/maps/api/geocode/json?address=THEADDRESS&region=XX&sensor=true
XX is the ccTLD code of the region, e.g. sg for Singapore.
