構建谷歌地圖API v2應用程序，但不幸的是.apk已停止工作

我想用Google Maps API v2構建應用程序，但事情是，應用程序一直給我提供錯誤，遺憾的是.apk已停止工作，儘管我遵循所有必需的說明。請查看我的代碼並幫助我找出問題所在。由於提前構建谷歌地圖API v2應用程序，但不幸的是.apk已停止工作

這裏是我的應用程序代碼

package com.example.ugoogle; 

import android.os.Bundle; 
import android.view.Menu; 
import android.view.MenuItem; 

import com.google.android.maps.MapActivity; 
import com.google.android.maps.MapView; 

public class MainActivity extends MapActivity { 

    MapView maps; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     maps = (MapView) findViewById (R.id.MapsViewMain); 
     maps.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 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

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

檢查，並與我們分享您的logcat，以確定我的代碼 – MTahir 2014-12-05 18:42:02

塔希爾·巴伊請提問題，你有沒有使用'logcat'？ – 2014-12-05 18:50:08

真正的罪魁禍首:) – MTahir 2014-12-05 18:51:30

嘗試將以此爲元素的子：

<meta-data 
android:name="com.google.android.gms.version" 
android:value="@integer/google_play_services_version" />
