我只是尝试在显示屏上查看地图,但它不起作用。我得到一个运行时异常:
01-17 19:16:47.066: E/AndroidRuntime(6605): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.maptest/com.example.maptest.MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

setContentView(R.layout.activity_main);

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

关键是 v2,我严格遵循我找到的谷歌教程。我还导入了安卓播放服务。
