Question

我正在尝试在模拟器上测试我的应用程序，但它无法正常工作。但是，它在我的手机上工作正常。我有一个版本4.0.3的三星Galaxy S2。如何创建一个可以使用它的模拟器？

这些是错误，它位于pastebin http://pastebin.com/PR65kGxg：

这是第89行：

public void setMapDefaults()
{
    map.setMapType(GoogleMap.MAP_TYPE_NORMAL); //line 89
    map.setMyLocationEnabled(true);
}

Answer 1

创建一个新的虚拟设备，并在目标中选择Google API等级17，它将有效。

Answer 2

您的应用使用地图API，因此请检查模拟器是否具有Google API 4.0目标，而不是简单的Android 4.0

Answer 3

确定。我阅读了SO复制指南并认为这个问题与this question不同，以便得出一个答案，说明“这可能是与这个问题相同的问题”类型答案/评论的事情。任何版主都可以自由地整理一下。

基本上 - 尽管NPE，Jonathan的代码仍然很好。这可能是模拟器 - Google V2 Play服务兼容性问题。

我的应用程序不能在模拟器上运行，但它将在我的手机上运行
