The MiniTouch command is sent to the Android10 version of the mobile phone, the screen does not perform the command action, what is the reason?

[EspenYan]

I independently used MiniTouch to send commands to the following Android10 mobile phones, and the mobile phone screen did not respond to operations.

Device Information：（abi version：arm64-v8a） HUAWEI Mate20Pro：S2D7N18B26001522 device product:LYA-AL00L model:LYA_AL00 device:HWLYA transport_id:4 SamsungNote9：271ddb713f1c7ece device product:crownqltezc model:SM_N9600 device:crownqltechn transport_id:5

Here are my steps：

1. Running the service:

>adb shell am startservice -a jp.co.cyberagent.stf.ACTION_START -n jp.co.cyberagent.stf/.Service
Output: Starting service: Intent { act=jp.co.cyberagent.stf.ACTION_START cmp=jp.co.cyberagent.stf/.Service }
>adb forward tcp:1100 localabstract:stfservice
Output: 1100

2. Running the agent:

>adb shell export CLASSPATH=/data/app/jp.co.cyberagent.stf-LfyY2eDJhikwqDyDVg-ayg==/base.apk;exec app_process /system/bin jp.co.cyberagent.stf.Agent
Output:Starting minitouch agent
Listening on @stfagent
>adb forward tcp:1090 localabstract:stfagent
Output:1090

3. Run MiniTouch:

>adb shell /data/local/tmp/minitouch
Output:

Is there a problem with my steps or the device does not support it? Thanks for answering
