我是android的初学者......我正在创建一个应用程序来加载谷歌地图v2。但它没有加载并且每次都会崩溃并显示一条消息不幸已关闭。请帮助我解决错误..提前致谢..我是一个普通的追随者堆栈溢出..

**my code**
**Main activity.java**
package com.mypack.test;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import android.os.Bundle;
import android.app.Activity;
import android.widget.Toast;

public class MainActivity extends Activity {

// Google Map
private GoogleMap googleMap;

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

    try {
        // Loading map
        initilizeMap();

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

}

/**
 * function to load map. If map is not created it will create it for you
 * */
private void initilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();

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

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

}

感谢您花费宝贵的时间。我得到了解决方案......这是我的错误......正如 Reghunandan 和 Patrik 所说。引用 google playstore 服务有问题..我的应用程序从 SDK 目录引用 google playstore 服务,而不是从在我的工作区中加载了谷歌 Playstore 的版本。所以上面的错误被清除了..在运行应用程序时,地图没有加载..我用下面的代码检查了它

     package myapp.mypack;

     import com.google.android.gms.common.ConnectionResult;
     import com.google.android.gms.common.GooglePlayServicesUtil;
     import com.google.android.gms.maps.GoogleMap;
     import com.google.android.gms.maps.SupportMapFragment;

     import android.os.Bundle;
     import android.support.v4.app.FragmentActivity;
     import android.view.Menu;
     import android.widget.Toast;

     public class MapActivity extends FragmentActivity {

String msgtype,sendernum;
// Google Map
private GoogleMap googleMap;
     @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if(check()) 
    {
        setContentView(R.layout.app_main);
        Toast.makeText(this, "In Google play service.", Toast.LENGTH_LONG).show();
        initFun();
    }
    else
    {
        Toast.makeText(this, "Google play service not available.",      Toast.LENGTH_LONG).show();
    }
}

private Boolean check()
{
    int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);
    if(status==ConnectionResult.SUCCESS)
    {
        return true;
    }

    return false;
}

public void initFun()
{
    SupportMapFragment sp = (SupportMapFragment)      getSupportFragmentManager().findFragmentById(R.id.map);
    googleMap = sp.getMap();
    googleMap.setMyLocationEnabled(true);
    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);


}

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

 }

但是我的地图正在加载...相反,它会显示一段时间的屏幕并显示“Google play 服务不可用”。如代码中所指定..但我检查了我的项目>属性> android。google playstore 库有一个绿色的勾号。所以认为这是我的Playstore版本的问题..*我在我的galaxy s3 mini中运行该应用程序。但它也显示相同的白屏..我在手机中的Playstore构建版本是:4.3.11。我唯一的解决方案是更新playstore并重新运行我的应用程序。logcat还显示我手机的playstore版本需要更新..请大家看看我的查询..是我手机的playstore版本有问题吗.. *
