无法请求 React Native Android 应用程序 AUG 2024 的权限

Question

我正在构建一个反应本机应用程序。我正在运行 Pixel 7 虚拟设备，我正在尝试请求访问手机文件系统的权限以从应用程序下载图像，但是我没有看到请求窗口弹出，并且权限设置为 never_ask_afain，即使我从来没有将其设置为这个。我已经重新安装了应用程序，尝试了不同的虚拟设备等等

const requestStoragePermission = async () => {
    if (Platform.OS === 'android') {
      try {
        console.log(Platform.OS);
        const granted = await PermissionsAndroid.request(
            PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
            {
              title: 'Storage Permission',
              message: 'App needs access to your storage to save the QR code',
              buttonNeutral: 'Ask Me Later',
              buttonNegative: 'Cancel',
              buttonPositive: 'OK',
            },
        );
        console.log(`Results... ${granted}`)
        return granted === PermissionsAndroid.RESULTS.GRANTED;
      } catch (err) {
        console.warn(err);
        return false;
      }
    } else {
      return true; // iOS does not need this permission
    }
  };

这是我的日志的输出

 android
 LOG  Results... never_ask_again

这是我的清单文件：

<manifest xmlns:android="http://schemas.android.com/apk/res/android">
  <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
  <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

    </activity>
  </application>
</manifest>

我正在使用React Native v0.73.4。

我希望出现权限窗口并询问用户是否会授予权限，但它永远不会这样做

Answer 1

解决步骤： 请求前检查权限：

确保您在请求之前检查权限状态。如果权限已设置为 never_ask_again，您可能需要将用户引导至应用设置以手动启用它。

修改您的代码以处理 never_ask_again：

清除应用程序数据或重置权限：

如果您一直遇到 never_ask_again 状态，请尝试清除应用程序数据或通过设备设置重置应用程序权限。
