Question

Seguo Google Maps Android "iniziare" tutorial- https://developers.google.com/maps/documentation/android/

Ma mi sono imbattuto in un errore "" Impossibile risolvere il simbolo 'OnMapReadyCallback', che potrebbe essere una correzione facile, ma mi sta sconcertando Questo è il codice che ho per le mie dichiarazioni di importazione per l'applicazione:

public class main extends FragmentActivity implements OnMapReadyCallback { 


    // Within which the entire activity is enclosed 
    DrawerLayout mDrawerLayout; 

    // ListView represents Navigation Drawer 
    ListView mDrawerList; 

    // ActionBarDrawerToggle indicates the presence of Navigation Drawer in the action bar 
    ActionBarDrawerToggle mDrawerToggle; 

    // Title of the action bar 
    String mTitle="";

     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main);

Answer 1

OnMapReadyCallback appena uscito in un recente aggiornamento all'SDK di Maps V2. Se lo desideri, devi eseguire l'aggiornamento a una versione abbastanza nuova di tale SDK.

Gli utenti di Android Studio possono passare a compile 'com.google.android.gms:play-services-maps:6.5.87', da the new Play Services granular dependencies, per ottenere questa nuova classe e possibilmente ridurre le dimensioni del loro APK come vantaggio collaterale.
