Question

我正在尝试在我的应用中显示google map，但它会显示小方块框而不是google maps

这是我的Mainactivity

public class MainActivity extends FragmentActivity {

    private static final int GPS_ERRORDIALOG_REQUEST = 9001;
    GoogleMap mMap;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (servicesOK()) {
            //Toast.makeText(this, "Google play services successfully connected.", Toast.LENGTH_SHORT).show();
            setContentView(R.layout.activity_map);
        }else{
            setContentView(R.layout.activity_main);         
        }        
    }    

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    public boolean servicesOK(){
        int isAvailable = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
        if (isAvailable == ConnectionResult.SUCCESS) {
            return true;
        }else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) {
            Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST);
            dialog.show();
        }else{
            Toast.makeText(this, "Can't connect to google play services.", Toast.LENGTH_SHORT).show();
        }
        return false;
    }

Answer 1

您必须获得此应用程序的API密钥

https://developers.google.com/maps/documentation/android/start#obtain_a_google_maps_api_key

在清单

中

   <meta-data 
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="08DEBUGKEYABCDEFBLAHBLAHBLAH"/>

Answer 2

我认为您的问题很简单，就是您没有在谷歌控制台中打开谷歌地图api在线去那里：https://cloud.google.com/console/project 点击您的项目，然后点击API和Auth，然后选择谷歌地图andorid api v2

这应该有帮助：）

Google地图无效
