使用谷歌地圖API和碎片活性的錯誤

說實話，我不知道是什麼導致了錯誤，我第一次使用它們。你能幫我解決這個問題嗎？我只是試圖啓動谷歌地圖API進入fragmentActivity。這是logcat的使用谷歌地圖API和碎片活性的錯誤

，這是類

import android.annotation.SuppressLint;

import android.support.v4.app.FragmentActivity; 

public class Map_activity extends FragmentActivity { 

    public static android.support.v4.app.FragmentManager fragmentManager; 

    @SuppressLint("NewApi") 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState);

     fragmentManager = getSupportFragmentManager(); 
    }

您確定此清單中的此行是正確的嗎？ package =「com.mom」。通常它看起來像com.companyname.myappname – noogui

是的，我確定。多數民衆贊成我是如何命名包 –

我有一個類似的問題和我通過將Google Play服務庫添加到我的項目中來修復它。將以下依賴項添加到您的Gradle文件中：compile 'com.google.android.gms:play-services:8.4.0'

我已添加谷歌播放服務庫。 –

我正在使用eclipse。日蝕中存在gradle。如果是的話我在哪裏可以找到它。 –

如果您在ADT中使用Eclipse，請查看將Google Play服務庫添加到項目的正確方法https://developers.google.com/android/guides/setup#add_google_play_services_to_your_project（選擇Eclipse with ADT） –
