Hello,
Welcome to our Microsoft Q&A platform!
First of all, please just only one android emulator. Then open Android Adb Command Prompt like following screenshot.
For example, I put a file to Desktop, then I want to copy this text file to sdcard, I used following command to execute it
adb push C:\Users\xxxxusername\Desktop\Topic.txt /mnt/sdcard/myfile.txt
Here is running screenshot.
Best Regards,
Leon Lu
