Question

作为一个整体来说，Java和Android开发都是新手，我只对C / C ++和Matlab有所了解。

我正在尝试运行Ti SensorTag应用。源代码在https://git.ti.com/sensortag-android/sensortag-android/trees/master

上提供

当我尝试在我的模拟器上运行时，应用程序崩溃了，我已尝试过4.4.2,4.4.3和5.

但是，在AndroidManifest.xml中，它引用的是一个根本不存在的ServiceActivity源文件。我有另一个版本略微调整（数据计算方式不同）应该可以正常工作，但也没有。不确定是否是导致问题的原因。任何人都可以尝试在他们的模拟器上运行这个应用程序吗？

我将发布logcat文件，如果你们需要查看任何实际代码，请告诉我。
