Is there any way that I can emulate USB POS thermal printer in an android emulator?
I ordered a printer online, but it will take some time to arrive. I was hoping to continue development in an emulated environment.
No, Terminal Providers shouldn't allow Developers to Emulate their Devices. You have to use the corresponding Terminal for USB Debugging Proposes. Because SDKs are different from Terminal to Terminal Providers

I am working on a new product, and I have developed a flutter application using Flutter Blue Plus for connectivity to a custom piece of hardware I designed. FBP currently only supports iOS and Android. Even though it is 2023, integrated BLE for Desktops is still a bit underdeveloped and I don't want to write platform specific BLE code yet. The solution is to use a USB Dongle that I have used in the past, which has the full stack and all the hardware to work on any OS with USB access (BLED112 by Silicon Labs). The customers will be required to buy the dongle for $15 until BLE support for desktops mature. I did this before and it was fine.
My question is how do I run an executable from Flutter, and read all of the standard output, without blocking?
I plan on using a simple Python script that interfaces to the dongle with the serial port and spits out GAP and GATT data in real time. I want to launch the Python script from Flutter when Linux/Windows/macOS is detected.
I want to make sure I am going down the correct path with this idea.
Use process_run package.
final shell = Shell();
await shell.run('''
# Display dart version
dart --version
# Display pub version
flutter doctor
''');
I use android studio and I ask about, can I connect the Samsung galaxy note 2 and Samsung galaxy j2 prime plus to android studio and run the flutter app on this device
I didn't find any tutorial on youtube and I need help...
It should also work with your phones. You might need to enable development mode first and maybe install some drivers.
From the Samsung homepage:
Plug your Samsung mobile device into your computer using a USB cable
If you are using a Windows computer, go to Samsung Android USB Driver for Windows, then download and install the USB driver onto your computer
Enable developer options on your device by going to Settings > About device > Software info and tapping Build number seven times. (Devices with Android 4.1 or older already have developer options displayed by default.)
Turn on USB debugging by tapping Settings > Developer options > USB debugging
See all the details here: https://developer.samsung.com/mobile/galaxy-sdk-getting-started.html
I downloaded the Suite for the phone, the Google USB drivers and the Phone's connection drivers. So far, the phone works perfectly with the PC but Eclipse still refuses to see the phone and Device Manager is convincing me that I have no hardware compatible with the Google USB drivers. Therefore the Google USB drivers are downloaded but not installed or assigned to any device. I followed every answer on stackoverflow that there is so far, but none have solved the problem.
First, set your device into USB / debug mode.
Second, after you connect your device to the USB make sure your drivers is installed properly.
And last verify that adb.exe can detect you device from cmd (if running in windows) ..(path to your SDK)\platform-tools\adb device
If last step fails, then re-install you device driver, it should be handled automatically by sony pc-companion for your xperia phone.
You also have to enable USB-Debugging in Settings->Developer Options on your phone.
I need to prototype an Android application which communicates to external hardware using serial I/O. Can the emulator send and receive serial data over a PC's com port?
The Android emulator itself supports this feature, I see people use
"emulator -qemu -serial COM1" on Windows PC
or
"emulatro -qemu -serial /dev/ttyS0" on Linux PC
I have not tried it by myself yet, but that is the way in the big picture.
I came across this:
http://code.google.com/p/android-serialport-api/
this library will let you use Java to access the serial port on your Android device
I am developing an Android app for a class I'm taking. I've been using the emulator to date. I know what to see if it runs on the real HW.
My PC runs Windows 7. I downloaded the latest google/Android USb driver. I have enabled the USB Debugging feature on the tablet already. When I plug the tablet into the PC via USB, the PC doesn't seem to see the tablet at all.
What do I need to do to get these two devices to see one another.
thanks,

HI, I'm using superpad 3, and just have adb connection over ethernet, all you need is type cmd: "connect your.pad.ip" and then Eclipse will see your device.
