HarmonyOS关闭相机后右上角状态栏还是会显示相机的红点

private stopCamera() { 
  //相机会话停止 
  this.mCaptureSession?.stop(); 
  this.mCameraInput?.close(); 
  //预览资源释放 
  this.mPreviewOutput?.release(); 
  this.mPreviewOutput2?.release(); 
  if (this.mCaptureSession) { 
    //相机资源释放 
    this.mCaptureSession.release(); 
    this.mCaptureSession = undefined; 
  } 
}
