我最近遇到了这个关于LOCATION服务权限的问题。我忘记在AndroidManifest.xml中添加android.permission.ACCESS_FINE_LOCATION。
所以，我想你也忘了加上
<uses-permission android:name="android.permission.CAMERA" />
在AndroidManifest.xml中

我做了几次清理和重建，最后开始工作，不知何故，构建缓存没有正确更新。

从AndroidManifest.xml中删除tools:node="remove"修复了我的问题。将<uses-permission tools:node="remove" android:name="android.permission.CAMERA"/>替换为<uses-permission android:name="android.permission.CAMERA"/>

我的建议，以处理这种情况是打开设置和直接用户直接适应的权利，见下面的例子：

import { Linking } from 'react-native';
import { Alert } from 'react-native';

const openSettings = () => {
  Linking.openSettings();
};

const askForPermission = async () => {
  try {
    const result = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
      {
        title: 'Storage Permission',
        message: 'App needs access to your storage to read files',
        buttonPositive: 'OK',
        buttonNegative: 'Cancel',
      },
    );
    if (result === PermissionsAndroid.RESULTS.GRANTED) {
      console.log('Storage Permission Granted.');
    } else if (result === PermissionsAndroid.RESULTS.DENIED) {
      console.log('Storage Permission Denied.');
    } else if (result === PermissionsAndroid.RESULTS.NEVER_ASK_AGAIN) {
      console.log('Storage Permission Denied with Never Ask Again.');
      Alert.alert(
        'Storage Permission Required',
        'App needs access to your storage to read files. Please go to app settings and grant permission.',
        [
          { text: 'Cancel', style: 'cancel' },
          { text: 'Open Settings', onPress: openSettings },
        ],
      );
    }
  } catch (err) {
    console.log(err);
  }
};
