java - Ti SensorTag 应用程序开发

Question

作为一个整体，我对 Java 和 Android 开发相当陌生，我只了解 C/C++ 和 Matlab。

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

当我尝试在模拟器上运行该应用程序时，该应用程序崩溃了，我已尝试过 4.4.2、4.4.3 和 5。

但是，在AndroidManifest.xml中，它引用了根本不存在的ServiceActivity源文件。我有另一个稍微调整过的版本(数据计算方式不同)，据说应该也可以工作，但两者都没有。不确定这是否是导致问题的原因。其他人可以尝试让这个应用程序在他们的模拟器上运行吗？

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。

SensorTag 应用程序无法在模拟器上运行，因为它们没有蓝牙支持。 http://developer.android.com/tools/devices/emulator.html#limitations
