Question

我正在使用PermissionsAndroid向用户请求权限。我已经使用了那里给出的示例代码。

try {
  const granted = await PermissionsAndroid.request(
    PermissionsAndroid.PERMISSIONS.CAMERA,
    {
      'title': 'Cool Photo App Camera Permission',
      'message': 'Cool Photo App needs access to your camera ' +
      'so you can take awesome pictures.'
    }
  )
  if (granted === PermissionsAndroid.RESULTS.GRANTED) {
    console.log("You can use the camera")
  } else {
    console.log("Camera permission denied")
  }
} catch (err) {
  console.warn(err)
}

每当我调用此方法时，它总是显示输出为＆＃34; 您可以使用相机＆＃34;。但是，我已从应用设置中禁用了该权限，但仍然始终将该权限显示为GRANTED

请确保以下条目位于AndroidManifest.xml

中

我在Xamarin Native中遇到同样的问题，只是在build.gradle中设置属性是不够的

Answer 2

你应该在官方文档中使用min targetSdkVersion作为23。

Permission Android Official Docs

在SDK版本23之前的设备上，如果权限出现在清单中，则会自动授予权限，因此检查和请求应始终为true。

PermissionsAndroid.request始终返回PermissionsAndroid.RESULTS.GRANTED
