Question

几天后，我尝试使用简单的Google Map（使用Google API V2）创建应用。我对桌面上的java（win / linux）有一点经验，但这是我进入android世界的第一步。

我的第一次成功，是“点头”灰色谷歌地图 - 我相信因为关键问题而没有加载瓷砖......

经过大量的帖子后线程（也在这里 - 感谢2全部！）我现在有一个APP在手机上崩溃:(但仍然没有地图......

我列出我的代码并请求4帮助 - 我错了什么？

package com.example.mapstests;

import android.os.Bundle;
import android.view.Menu;
import android.widget.Toast;

import com.example.mapstests.R;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapView;


public class MainActivity extends MapActivity {

//  private GoogleMap mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
    private GoogleMap gMap;


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

        try {
            // Loading map
            initilizeMap();

        } catch (Exception e) {
            e.printStackTrace();
        }


        MapView mapView = (MapView) findViewById(R.id.map);
        mapView.setBuiltInZoomControls(true);


    }

    @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;
    }

    @Override
    protected boolean isRouteDisplayed() {
        // TODO Auto-generated method stub
        return false;
    }

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


     // Map wird mit Sicherheit geladen, gibts keine soll Fehlermeldung auftauchen 
    private void initilizeMap() {
        if (gMap == null) {
            gMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.map)).getMap();

            // check if map is created successfully or not
            if (gMap == null) {
                Toast.makeText(getApplicationContext(),
                        "Sorry! unable to create maps", Toast.LENGTH_SHORT).show();
            }
        }
    }

}

在这里我的清单

     </LinearLayout>

</LinearLayout>
