【解决方案1】：

您似乎遇到了空指针异常：

Caused by: java.lang.NullPointerException at 
android.graphics.Bitmap.compress(Bitmap.java:1544) at 
com.huawei.hmsscankitexample.activity.ProfileActivity.downloadQrCode(ProfileActivity.java:218)

【解决方案2】：

您可以查看华为开发者网站上的文档以获取有关结果代码的更多信息。这是link。

结果码10009“应用正在进行的数据导出任务数超过上限（3）。”

下面链接中提供的答案进一步解释了发生此错误的原因。 HMS Awareness Kit-Error code 10011 is returned after the SDK is integrated

This error is caused by too frequent API calls. Currently, there are two restrictions on calling the APIs of HUAWEI Awareness Kit:
 
1.  The number of API calls within 1 hour cannot exceed 1000.
2.  The number of API calls within 5 seconds cannot exceed 20.
 
The reasons for such restrictions are as follows:
 
1.  Frequent API calls in a short period of time are not normal service requirements.
2.  Frequent API calls increase the workload of HMS Core and even cause a failure to provide services for other developers.
 
The restrictions are only a temporary workaround, and will be eliminated after service optimization.
