用于模拟Android传感器的openintent的替代方法

Pankesh 发表于 Dev

潘克什

我正在为Android移动设备开发可扩展的传感和数据处理框架。它将启用可通过Android移动设备访问的各种数据信号（例如，温度，电池，压力，wifi信号强度等）。

为了测试传感器，我将编写的android代码部署在我的Android设备上。在这里，限制来了-我的android设备具有一组有限的传感器（例如，它没有温度传感器）因此，我无法测试所有类型的传感器（例如温度，压力，等等。）。

在Internet上，我已经检查了SensorSimulator项目（），但是它不适用于我。我收到以下错误。

直流电

调用SensorManager.connectSimulator()构成了网络操作，如堆栈跟踪所示。因此，您试图在应用程序的主线程上执行网络操作。Android默认情况下不允许这样做，因此您有两个选择。

使用另一个线程或异步任务。AsyncTask语法和用法约定可能会有些混乱，因此这里有一个示例：AsyncTask Android示例。
关闭严格模式 （不推荐）。
