The main issue is your android:minSdkVersion="16"
主要问题是你的android:minSdkVersion="16"
What original docs said is 原始文档说的是什么
If your android:minSdkVersion > 12
then you should use MapFragment
with extends Activity
如果你的android:minSdkVersion > 12
那么你应该使用带有extends Activity
MapFragment
And 和
If your android:minSdkVersion < 12
then you should use SupportMapFragment
with extends FragmentActivity
如果你的android:minSdkVersion < 12
那么你应该使用SupportMapFragment
和extends FragmentActivity
Try to replace 尝试更换

See this link provided by android official website How to add static fragment from XML 请参阅此官方网站提供的链接如何从XML添加静态片段
Try adding this to your onCreate(). 尝试将此添加到您的onCreate()。
SupportMapFragment mapFragment =
(SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
and replace this. 并替换它。
