    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main);

Answer 1

嘗試刪除這一行：

class="com.google.android.gms.maps.SupportMapFragment" 

從XML文件中的片段，它不應該是那裏。

2.更改此權限：

<permission 
android:name="android.os.Bundle.permission.MAPS_RECEIVE" 
android:protectionLevel="signature" /> 

這樣：

<permission 
android:name="com.example.mapdemo.permission.MAPS_RECEIVE" 
android:protectionLevel="signature" /> 

如果com.example.mapdemo是你的項目包。 如果不將其更改爲你的項目包在此權限，這：

<uses-permission android:name="com.example.mapdemo.permission.MAPS_RECEIVE" /> 

Answer 2

你有複製谷歌播放，而不是services.jar鏈接到谷歌播放services_lib項目？

認真遵守本：https://developers.google.com/maps/documentation/android/start

Answer 3

嘗試從Android SDK中導入項目： /演員/谷歌/ google_play_services_libproject/google_play_services_lib 到您的工作空間在內部消除您的應用程序添加任何文件夾/ lib目錄庫。

做到這一點後，將它們添加在您的：項目>屬性>安卓>庫添加
