如何解决getMapAsync（this）崩溃？

嘿我试图让位置服务工作在Android Studio和.getMapAsync（这）不断崩溃的应用程序。如果任何人都可以告诉我我搞乱了什么，我会非常感激。如何解决getMapAsync（this）崩溃？

GoogleMap memberMap; 
GoogleApiClient memberAPI; 
LocationRequest memberLocationRequest; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    if (googleServicesAvailable()) { 

     setContentView(R.layout.activity_main_page); 

     onMapReady(memberMap); 
    } else { 
     Toast.makeText(this, "Google services not available", Toast.LENGTH_LONG); 
     //to be done 
    } 
} 
@Override 
public void onMapReady(GoogleMap googleMap) { 
    memberMap = googleMap; 

    //memberMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); 
    SupportMapFragment mapFragment =(SupportMapFragment) getSupportFragmentManager() 
      .findFragmentById(R.id.mapfragment); 
    mapFragment.getMapAsync(this); 





    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 
    if(!locationManager.isProviderEnabled((LocationManager.GPS_PROVIDER))){ 
     buildAlertMessageNoGps(); 
    } 

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) { 
      buildGoogleApiClient(); 
      memberMap.setMyLocationEnabled(true); 
     } 
    } 

}

使用LogCat检查与您的崩溃相关的Java堆栈跟踪：https://stackoverflow.com/questions/23353173/uncomfort-myapp-has-stopped-how-can-i-solve-this – CommonsWare

请致电getMapAsync(this)从onCreate()方法。

更新您的代码如下：

GoogleMap memberMap; 
GoogleApiClient memberAPI; 
LocationRequest memberLocationRequest; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    if (googleServicesAvailable()) { 
     setContentView(R.layout.activity_main_page); 

     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.mapfragment); 
     mapFragment.getMapAsync(this); 
    } else { 
     Toast.makeText(this, "Google services not available", Toast.LENGTH_LONG); 
    } 
} 

@Override 
public void onMapReady(GoogleMap googleMap) { 
    memberMap = googleMap; 

    LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); 
    if(!locationManager.isProviderEnabled((LocationManager.GPS_PROVIDER))){ 
     buildAlertMessageNoGps(); 
    } 

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { 
     if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) { 
      buildGoogleApiClient(); 
      memberMap.setMyLocationEnabled(true); 
     } else { 
      buildGoogleApiClient(); 
      memberMap.setMyLocationEnabled(true); 
     } 
    } 

    // Add markers 
    LatLng sydney = new LatLng(-34, 151); 
    memberMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
    memberMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
}
