Question

我是android开发的新手，每当我尝试启动此活动时，它都会崩溃。我已经尝试过只有hello world并且意图很好，我认为它可能是Manifest中的东西，但我不确定它应该如何用maps api v2形成。我发现这个问题真的令人沮丧。任何帮助深表感谢。清单XML：

CRASH可能的原因。

您正尝试在模拟器中运行它。

您尚未在您的Manifest.in应用程序中包含API密钥。

 <application>
 <!-- some other code in the manifest -->
  <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="YOUR_API_KEY"/>
</application>

将Map Fragment添加到Main.java

GoogleMap googleMap;
  // Getting reference to the SupportMapFragment of activity_main.xml
  MapFragment fm = (MapFragment) getFragmentManager().findFragmentById(R.id.map);

    // Getting GoogleMap object from the fragment
    googleMap = fm.getMap();
