推荐答案

最好避免使用库进行权限检查

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

重要 - 在清单文件中包含上述代码行

 import { PermissionsAndroid, Platform } from 'react-native';

  componentDidMount() {
       if (Platform.OS === 'android') {
              this.requestLocationPermission(); // function call
         }
   }

下面的code包含function主体.

  async requestLocationPermission() {
     try {
       const granted = await PermissionsAndroid.request(
        PermissionsAndroid.PERMISSIONS.ACCESS_FINE_LOCATION
      );
      if (granted === PermissionsAndroid.RESULTS.GRANTED || granted === true) 
       {
          // WHAT TODO WHEN PERMISSION IS GRANTED
       } else {
         // WHAT TODO WHEN PERMISSION IS NOT GRANTED
      }
    } catch (err) {
      log(err);
    }
  }
