@performance/reasonable-gps-use-check
=====================================

无长时任务的应用退到后台时，禁止使用定位服务。

#### 规则配置

// code-linter.json5
{
  "rules": {
    "@performance/reasonable-gps-use-check": "suggestion",
  }
}

#### 选项

该规则无需配置额外选项。

#### 正例

import { UIAbility } from '@kit.AbilityKit';
import { geoLocationManager } from '@kit.LocationKit';

export default class EntryAbility extends UIAbility {
  onForeground(): void {
    //在前台时按业务所需创建定位请求
    let requestInfo: geoLocationManager.LocationRequest = {
      'priority': geoLocationManager.LocationRequestPriority.ACCURACY,
      'timeInterval': 0,
      'distanceInterval': 0,
      'maxAccuracy': 0
    };
    let locationChange = (location: geoLocationManager.Location): void => {
      console.log('locationChanger:data:' + JSON.stringify(location));
    };
    //监听位置的变化
    geoLocationManager.on('locationChange', requestInfo, locationChange);
  }

  onBackground(): void {
    //退后台取消监听
    geoLocationManager.off('locationChange');
  }
}

#### 反例

import { UIAbility } from '@kit.AbilityKit';
import { geoLocationManager } from '@kit.LocationKit';

export default class EntryAbility extends UIAbility {
  onForeground(): void {
    //在前台时按业务所需创建定位请求
    let requestInfo: geoLocationManager.LocationRequest = {
      'priority': geoLocationManager.LocationRequestPriority.ACCURACY,
      'timeInterval': 0,
      'distanceInterval': 0,
      'maxAccuracy': 0
    };
    let locationChange = (location: geoLocationManager.Location): void => {
      console.log('locationChanger:data:' + JSON.stringify(location));
    };
    //监听位置的变化
    geoLocationManager.on('locationChange', requestInfo, locationChange);
  }

  onBackground(): void {
  }
}
