# 应用设备监控

### 背景介绍

***

为确保应用在一体机眼镜上运行效果，建议尽量降低应用的整体功耗，开发者可通过以下工具可以监控应用运行时的电流情况，方便调试。<br>

### 使用须知

***

1. 在调用api之前，需要先阅读[设备监控 ](/rayneo-devdoc/x-xi-lie/unity-kai-fa/x2-api-jiu-ban-sdk-zhi-chi/platformandroid/she-bei-jian-kong.md)。
2. 需要在manifest中加入配置：

```xml
 <queries>
  <package android:name="com.ffalcon.rayneo.systemwindows" />
 </queries>
```

<br>

### Static Public Member Function
