如何在xamarin.forms pcl项目中配置地图？

我用xamarin.form PCL创建了一个项目.

我已经添加了 .....

根据所有平台(Android,iOS,Window Phone)的要求添加了xamarin.forms.maps和其他库和NuGet Package.

我在所有平台上都给出了所有权限和配置.

我已成功在窗口电话中显示地图和运行程序,但我在android中有错误.

错误是

更新后所有nuget包我得到以下错误...

有没有其他方法可以使用xamarin在android,iPhone和Window手机中轻松集成地图？

如果您使用的是Visual Studio;

右键单击Droid项目,转到Android Options选项卡,单击Advanced并设置Java Max Heap Size为1G

如果您正在使用Xamarin Studio,它应该是类似的东西.

它与所有正在加载的Java绑定有关,它会加载大量内存.使用此设置可以增加可用的默认内存.

你可以在一段时间之前在Xamarin的相关错误中阅读更多关于它的内容.https://bugzilla.xamarin.com/show_bug.cgi?id=8137#c14
