Hello,
Unfortunately, creating the implementation of Android apps is out of our scope of support.
However, you could use the following java command to execute shell commands and then perform the serial connection as it should be in a Linux terminal. However, this is a suggestion, we cannot guarantee if this will work.
Process process = Runtime.getRuntime().exec(command);
//Where command, is the Linux command that you are willing to execute
I apologize for the inconvenience this may give you.
Best regards,
Diego.
