I was looking to create a mobile application for this handheld thermal printer device.
This application is Win CE based. Does anyone know if there is a similar device with Android O.S(Having printer and barcode reader) ?
The sourcecode for the zxing project is open source and fairly simple to use, could that not work for what you want?
Google code ZXing
As far as Im aware there aren't any devices such as that one, but it may happen later on down the line, if the manufacturers who sell those devices see Android as a viable / cost effective route to take (but this would involve losing all the investment in the windows CE platform)

I have an android device running a custom ROM and self-developed apps.
Android version: 8.1 (API level 27)
There is a temperature and humidity sensor built into the android device. Now I want to feed the sensor data into my smart home system using Matter.
I´m not familiar with C++ and other languages apart from Java/Kotlin and Python. So is there any way to send the sensor data to my Amazon Echo Smart Home Hub via the Android software with Matter?
It would also be good if it could work independently of the Smart Home system (Google, Apple, Samsung, etc.).
I have checked out the Matter Github repository. There are some example apps and I tried to apply it to my issue. But I did not get any further at this point.
Any help is much appreciated.
An android app might not be the best path for this, as it cannot stay on and listen to external communications all the time. You can look for solutions to run a local server on the android system and implement a virtual device that way. Also, you can download the matter specification from the CSA website https://csa-iot.org/all-solutions/matter/ and take a look at how to implement matter communications.
I have been searching for a while now and decided to post a question here to see if someone had already traveled down this specific road.
I am developing a bluetooth enabled device, using the Bluegiga BLE112 chip. They announce this chip to be easily used with iOS devices (and this was our main reason for choosing it)
The device will need to communicate with an App, that we need to be developed for iOS, Android, Windows Phone, and Blackberry. Due to this need, I've decided to use Rhomobile, as it seems to be the only one that supports developing BT apps for iOS without having to develop further plugins.
I only need to send small messages (like commands, small strings) and sometimes a bigger file to the device's internal memory.
On Rhomobile's BT documentation, they state that for iOS it is only possible to comunicate between iOS devices ( i'm thinking that they say this because of the MiFi limitations imposed by Apple, but that using Bluegigas chip are not a problem...)
My question is:
Since Bluegiga's documentation has examples of devices communicating with iOS using their chip, i should be able to develop using Rhomobile and not suffer from the limitation stated above. I wanted to be as sure as possible before making my company spend money ordering the chips and development board and what not..
Has anyone tried this, is my thinking missing something?
Thank you all for your time.

Good Question, I think I can understand the reason for your confusion.
The main reason is many people/products/frameworks does not clearly mention if they are talking about Bluetooth Classic or Bluetooth Low Energy (BLE).
These are both 2 different things and even thougfh they are called "Bluetooth" one cannot talk to the other.
(Some devices can be both Classic and Bluetooth Low Energy, which allows it to connect to either types)
Ok now comming to your Question :
THE bluegiga dongle is BLE
The Rhomobile is refering to the Bluetooth Classic version of the API.
On iOS the BLE APIs are open to applications, but Classic is limited on iOS , one way for Apps to use Classic Bluetooth on iOS is via the Gamekit APIs but that is possible only when talking with iOS devices, so it wont connect to another Android or Win device that is also Classic.
Needless to say with BLE APIs you cannot connect to calssic anyways.
The bluegiga examples are BLE examples, and apple also has good documentation and examples / samples on how to use BLE so yes it is easy to build a device and app using BLE on iOS.
There is nothing special abut any particular chip yo ucan use any BLE chip - there are many vendors today.
BUT Android (and I guess Windows as well) does not yet have BLE APIs for applications to use :( (Bit I think is is comming soon :))
So I hope this clears things up a bit.
hi im trying to make a POS app for android using adobe air mobile .
i have an epson thermal printer connected to a Wifi router.
i have learned that printjob won't work with the mobile apps
Please give me some solution for this
I have seen people go about this in three different ways:
Use an API from a printer manufacturer
Use a 3rd party printing app
Write your own driver
From experience, #1 is by far the best option. It's much better to use an API because it allows you full customization over print outs (font, special device commands, etc) and it reduces the amount of time you need to spend researching and coding.
3rd party printing apps are limited in customization. They might be good for a full size office or home printer, but POS printing usually has more specific requirements and often needs a level of customization these apps can't offer. Writing a driver is hard because there are so many things you need to intimately know about the printer: how to establish communication, get status, format the receipt, and more. It's like spending months to reinvent the wheel because a well-constructed API handles all of this for you.
I highly recommend you check out Star printers. They have a great Android SDK with a printing API that's full of samples and it's heavily documented. http://www.starmicronics.com/support/sdkdocumentation.aspx
I have a fairly large windows mobile app (written in NETCF 3.5). Those in power at my company are wanting to convert this app to run on Android.
What similarities are there between Android development and Windows Mobile (not Windows Phone) development? Specifically:
Window Forms (ie the UI)
P-invokes (my app has a lot of these)
WCF/SOAP web services support
C# and Visual Studio Development tools
Also, if you feel inclined, I would like a general statement on how a conversion would be from someone who has done it. (Keep in mind that I have never made an Android app.)
Background:
Someone (a non-programmer) here did a Google search and found a "tool" that converts Windows Mobile apps to Android for you (push of the button kind of thing). That person now has everyone believing that this conversion will take no time at all.
As a developer that has worked on several platforms, I just find that really hard to believe (though I would be happy to be wrong).
check out Will Google Android ever support .NET? as it might be what you're looking for. Not sure how well it works, but if the non-programmer is willing to front the money, I say give it a try
Update:
Looks like mono switched companies:
http://xamarin.com/monoforandroid
The short answer in NONE. Android is running Linux that is restricted to Java applications. If you want to port an application from .net to Android, you are looking at a total rewrite.

There is the monodroid project, which takes .NET applications and makes them run on Android's OS, but it's still very experimental and in no way ready for production applications. Otherwise, to mirror "Sam's" comment above, there are no similarities really. I've been building mobile apps for 11 years (delivered over 60 on various Windows flavors) and the Android model is very different than what you might have done in the past on Windows CE 5 or Windows Mobile 6 type systems.
Is it possible to install Android in a normal mobile phone?
I have Sony Ericsson Naite which has only key pad interface (No touch). I would like to install Android in my phone for experimenting with it. It will be great if its possible to dual boot Android with Symbian :-).
Do we need any other special hardware to install operating system in a mobile phone? Will Android work on a key-pad mobile?
Any pointer/suggestion is appreciated.
Thank you in advance.
The Naite is a fairly simple handset running on the Sony Ericsson JP8 platform.
End users are not supposed to be able to update the firmware on the phone.
Only Sony-Ericsson partners are supposed to get the PC software to update the firmware and only Sony-Ericsson is supposed to be able to create new firmwares.
(maybe you can hack the phone so you get it to boot on android or symbian but that's going to be unsupported behavior that nobody will guarantee)
If you want to experiment with creating your own android firmwares, I suggest buying an ADP2 handset from google.
If you want to experiment with creating your own Symbian firmwares, I suggest buying a Texas Instrument Zoom 2 device since it is the reference platform for Symbian.
The Zoom 2 seems to also support Android, by the way.
If you just want to experiment with application development on both platforms, I suggest using the two SDKs and emulators first.
There are some pretty cheap Symbian phones out there, particularly in the Series60 3rd edition range and, depending on where you live, you might even be able to find a Pay-As-You-Go Android phone like the Pulse.
I STRONGLY encourage you to go visit the XDA Forums and visit their Android sections for this kind of information.
