react native image picker在android中不工作时启动摄像头

我在react native for capture image中使用了

“react native image picker”：“^3.0.1”

。但是我在android 9中打开相机时出错了

我得到一个错误：

{"errorCode": "others", "errorMessage": "This library does not require Manifest.permission.CAMERA, if you add this permission in manifest then you have to obtain the same."}

这是我的密码

ImagePicker.launchCamera(
{
includeBase64：错误，
mediaType:'照片'，
质量：0.8，
},
异步（响应）=>{
if（response.didconcel）{
log（'User cancelled image picker'）；
}else if（response.error）{
log（'ImagePicker错误：'，response.Error）；
}否则{
}
},
);在拍摄图像之前，向用户请求相机许可。在安卓上面的棉花糖版本中，您还应该请求运行时权限，这称为危险权限

const requestCameraPermission = async () => {
  try {
    const granted = await PermissionsAndroid.request(
      PermissionsAndroid.PERMISSIONS.CAMERA,
      {
        title: "App Camera Permission",
        message:"App needs access to your camera "
        buttonNeutral: "Ask Me Later",
        buttonNegative: "Cancel",
        buttonPositive: "OK"
      }
    );
    if (granted === PermissionsAndroid.RESULTS.GRANTED) {
      console.log("Camera permission given");
    } else {
      console.log("Camera permission denied");
    }
  } catch (err) {
    console.warn(err);
  }
};

然后如果授予了权限，则在
if
内调用

ImagePicker.launchCamera

这对我有帮助

将选项添加到android\app\src\main\AndroidManifest.xml->sectionapplication
->paramandroid:requestLegacyExternalStorage=“true”

android\app\src\main\AndroidManifest.xml

...
    <application
      ...
      android:requestLegacyExternalStorage="true"
      ...>

remove``Manifest.permission.CAMERA``如果在Manifest中设置，则删除错误消息中注明的权限我已尝试过，但仍收到此问题remove``Manifest.permission.CAMERA``如果在Manifest中设置，则删除错误消息中注明的权限我已尝试过，但仍收到此问题
