나는 이것을 수행하고 내 장치에서 작동해야합니다. 시도 해봐. 로드 맵

package br.com.example.mapsexample; 

import android.app.Activity; 
import android.os.Bundle; 
import android.widget.Toast; 

import com.google.android.gms.maps.GoogleMap; 
import com.google.android.gms.maps.MapFragment; 
import com.google.android.gms.maps.model.LatLng; 

public class MainActivity extends Activity { 

    GoogleMap mGoogleMap; 

    @Override 
    protected void onCreate(final Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     this.setContentView(R.layout.activity_main); 

     try { 
      this.initializeMap(); 
     } catch (final Exception e) { 
      // TODO: handle exception 
     } 

    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     this.initializeMap(); 
    } 

    private void initializeMap() { 
     if (this.mGoogleMap == null) { 
      this.mGoogleMap = ((MapFragment) this.getFragmentManager().findFragmentById(R.id.mapFragment)).getMap(); 

      if (this.mGoogleMap == null) { 
       Toast.makeText(this.getApplicationContext(), "Is not possible load the map", Toast.LENGTH_SHORT).show(); 
      } 

     }

Answer 3

내가 가진 같은 일을했다.

당신의 MostraAlunosProximos 클래스에서 OnCreate이 시도

,

int status = GooglePlayServicesUtil 
       .isGooglePlayServicesAvailable(getBaseContext()); 

     // Showing status 
     if (status != ConnectionResult.SUCCESS) { // Google Play Services 
                // are 
                // not available 

      int requestCode = 10; 
      Dialog dialog = GooglePlayServicesUtil.getErrorDialog(status, 
        this, requestCode); 
      dialog.show(); 

     } else { // Google Play Services are available 

      SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager() 
        .findFragmentById(R.id.mapa); 

      // Getting GoogleMap object from the fragment 
      if (fm != null) { 
       googleMap = fm.getMap(); 
      } 

// Enabling MyLocation Layer of Google Map 
      googleMap.setMyLocationEnabled(true); 
} 

그리고 XML 파일의 fragment 내부에이 라인 android:name="com.google.android.gms.maps.SupportMapFragment"을 추가합니다. 그리고 나는 거기에 구글 플레이 서비스에 대한 두 메타 데이터가 있다는 것을 볼 수 있습니다.

희망 하시겠습니까?
