Google Maps与其他Android版本/设备的兼容性

Question

我已经开发了一个Android应用程序，该应用程序使用Google Maps API v2来显示一张地图，该地图可以显示用户位置，其他不同点（商店...），一个跟踪蓝点，该蓝点代表用户移动时和指向特定位置的方向。

所有这些都可以在某些设备上正常运行，但在其他设备上则无法正常运行，我不知道为什么？

适用于Android 4.2.2、4.3、2.3.7

但不适用于Android 2.3.6，例如4.0.1。

是否与其他设备上未安装的Google Play服务相关？

我的代码有问题吗？

我相信Google Maps有一些更新，这些更新未应用在较旧的设备上。 尝试更新较旧的设备（如果未这样做）。 或者只是为旧设备制作另一个版本的应用程序
