我无法使用基本的 Google Maps V2
I can't get the basic Google Maps V2 to work
已回答。
我已按照此处的说明进行操作 http://www.androidhive.info/2013/08/android-working-with-google-maps-v2/
另一个网站基本上说的是同样的话，但我就是无法让它工作。
我（希望）正确导入了 google-play-services-lib，并为我的程序获取了 SHA1 密钥。
这是基本程序的代码

@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
// Loading map
initializeMap();
} catch (Exception e) {
e.printStackTrace();
}
}
/**

private void initializeMap() {
if (googleMap == null) {
googleMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
// check if map is created successfully or not
if (googleMap == null) {
Toast.makeText(getApplicationContext(),
"Sorry! unable to create maps", Toast.LENGTH_SHORT)
.show();
}
}
}
@Override

super.onResume();
initializeMap();
}
