请帮助我。我尝试了一些解决方案，但我没有得到结果提前致谢..

The Google Play services resources were not found. Check your project configuration to ensure that the resources are included.

看起来您没有正确设置 google play 服务。

按照以下链接中的步骤设置 google play 服务。

http://developer.android.com/google/play-services/setup.html

您还需要检查 google play 服务的可用性。在下面的链接中查看主题检查 Google Play 服务。

http://developer.android.com/training/location/receive-location-updates.html

你的最小 sdk 是 14

<uses-sdk
    android:minSdkVersion="14"

因此您需要使用MapFragment 而不是SupportMapFrament。

更改为

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/map"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:name="com.google.android.gms.maps.MapFragment"/>

替换

public class MainActivity extends FragmentActivity {

通过

public class MainActivity extends Activity {

改变

map = ((SupportMapFragment)  getSupportFragmentManager().findFragmentById(R.id.map))
               .getMap();

到

map = ((MapFragment)  getFragmentManager().findFragmentById(R.id.map))
               .getMap();
