Flutter 尝试在此处运行颤振示例时出错

因此，我试图在这里集成到我的颤振应用程序。所以我一直在关注这一页，让它发挥作用

我试图运行hello_地图示例，但无法使其运行

我做了上面提到的所有步骤（包括用我自己的设置com.here.sdk.access_key_id和com.here.sdk.access_key_secret），但当我运行应用程序时，我在控制台上得到了这些，什么都没有发生

我已经试着运行一个我自己的示例来执行上面提到的步骤，但也没有成功

编辑： 我按照建议纠正了关于颤振医生的所有问题：

在那之后，我尝试运行这个示例，但得到了相同的错误

Bellow是控制台上颤振运行-v的输出：

更新Android Studio。如果部分安装了29.0.3，请转到Android Studio的sdk管理器完全安装。或更新29.0.3。它对我起了作用

第一个屏幕截图显示您与设备失去了连接，这听起来与颤振或HERE SDK无关

第二张截图上的Flatter doctor表明您错过了接受Android许可证的机会。当您按照屏幕截图中建议的步骤操作时，此问题应该消失了。此外，它还说根本没有可用的设备（或模拟器/模拟器）。这听起来不像你可以运行任何颤振应用程序。。。真奇怪。我会先试着让弗利特医生满意

您是否使用“颤振运行”从命令行运行？也许它也值得在Android Studio中尝试，我可以在iOS>13模拟器和Android模拟器上运行它而不会出现问题。我正在Mac OS X 10.15.2上使用Android Studio 3.5，Flatter v1.15.21-pre.11。

感谢您的快速回复。我照你说的做了，但没有解决我的问题。你有没有用安卓工作室做过安卓项目？如果没有，那么制作一个并运行它。然后再次运行Flatter doctor并检查发生了什么我在Android Studio上有更多的项目。老实说，我所有的项目都在进行中。我真的不认为这是AS的问题，我认为问题是特定于here sdk的。因为如果我从pubspec.yaml中删除hereSDK，应用程序运行就很好。您是否使用here sdk运行了一个示例？安卓还是iOS？你用的是什么版本的颤振？再次感谢。我的颤振版本和你的一样。我用安卓系统运行。试着运行这个颤振博士——android licensesHi，谢谢你的回复。按照你的建议做了，但仍然无法运行示例。编辑了文章并添加了更多内容。提前感谢您尝试在与您相同的颤振版本上运行。但是在最后几行的时候又犯了同样的错误，你连接到互联网了吗？否则，hereSDK将无法工作，您将看到一个空白屏幕。您也可以联系此处的支持服务，他们应该能够快速地进一步调查此问题。是的，我一直连接到internet。我已经在努力达到这里的支持，但这里的技术问题告诉寻找这样
