Android is a mobile operating system developed by Google, based on the Linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. Android's user interface is based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects, along with a virtual keyboard for text input. In addition to touchscreen devices, variants of Android are also used on notebooks, game consoles, digital cameras, televisions, automobiles and other electronics. Applications are usually developed in Java programming language using the Android software development kit (SDK), but other development environments are also available, including Delphi, Ruby and Visual Studio (using C++).

We are trying to develop an android application that would interface with a Bluetooth NFC Reader, namely ACR1255U from ACS.
The app should detect iof the tablet is paired with the Bluetooth reader, be able to detect if a card is read by the reader and read the tag from the card.

Does anyone have experience in this to point us in the right direction?

Thanks in advance.

Looking for help.

Thanks!

I would like to monitor my son's use of his Android phone. I do not wish to block anything. I would however like to receive reports of websites that he has visited, youtube videos that he has watched and other things that I haven't thought of. I would like to be able to install this on his phone without him being aware. Also, presumably it must also be possible to intercept traffic through our router and make some kind of record of that traffic. What is available? Obviously that doesn't help when he is not using the router, so I am interested in both approaches.
Thank you

Hi there.

I have this Samsung Galaxy Note Pro with the awesome 12.2 inch screen. I love the size, but the hardware/motherboard is getting too old/slow for new games etc.
Since Samsung didn't care to make a new edition with this screen size, I wonder if it is possible to replace the motherboard with a newer one from S4, S5e or even the brand new S6? Anyone experimented with this?
All considered... screen resolution is the same. So that should just be a matter of connecting it the the MB. Of course I don't expect screws to fit, but lots can be done with hot glue. I just want to reuse screen, case and battery. :-)

best regards

I am developing a Xamarin application using Visual Studio 2017 on a Windows 10 laptop. I can run the app and see output on the Android emulator. How do I connect my Android phone to my computer and see the output on my phone?

Part of bundled O365, we get Activesync MDM that could do remote
wipe of our corporate phones.  However, we found that this remote
wipe for 'full wipe' (ie mailbox plus the phone OS) doesn't wipe the
the OS of certain Android phones but only the mailbox which Audit
gave a finding : it's desired to wipe entire phone.

We log a case through reseller (understand reseller further log with
MS) but did not get any reply, thus enquiring here:

Q1:
is there a list of published phone models that MS Activesync
supports for 'full remote wipe'?

Q2:
Is this specific to Android's specific version or it sounds more
like hardware specific/dependent?

Q3:
Any other workarounds other than training staff not to export
their emails out of the phone or take screen shots to save in
the phone??

Gboard for Android and Windows desktop

I absolutely love Gboard. It works so seamlessly for voice-to-text, and for allowing you to re-use text clippings. The problem is that it only seems to be available for Android and iOS. I don't think there is a way to use it in Windows? This is disappointing, to say the least. Any assistance in finding some way to cross-platform this ability would be greatly appreciated.

I have one user who cannot consistently send email from his Galaxy S10+ through our Exchange server. He receives all his email. He can send through GMail. He can send once in a while through our Exchange Server. Most of the time, they stay in the outbox on his phone. He has replaced the phone and the problem remains. Other users have no issues.

Ideas?

Since a couple of weeks, my smartphone, without any intervention of me, power off.
This happens several (between 5 and 10) times a day.
First I suspected the battery, and replaced it by a new one.
But the behaviour continues.
What shall I do to fix this ?
The smartphone is a Samsung S4 mini

Hi, I've used RAD studio Tokyo/Delphi to create a program for Android. I have this program working and looking good on my Amazon Fire. It occurred to me that a nice embellishment for this program would be a click sound for when the user presses a button...feedback. I remember about 35 years ago when Casio came out with calculators that could beep for each keypress. I found this useful and missed it when they stopped including sound a couple of years later.
I started to research this and found that Android prefers .3GP audio files. There don't seem to be any audio files on the fire.
What I am thinking is I would produce four very short audio files and save or convert them to .3GP. They would be tied into buttons as part of an on-click event. I would use a TMediaPlayer. There would be a tick, a tock, and two other similar sounds.
My questions are: Should I use one Media player, or four ? Are there no built-in sounds I can use, or a different way to generate sounds ? Or is this all a bad idea perhaps because it would be too much for the Fire ? Should these files be stereo ? What sampling rate and bit depth ?

I have just used RAD Studio Tokyo to complete my first program for Android. I have this program running well on my Amazon Fire.

There is one odd problem I am having with text. I am using Edit boxes for entry and display of numbers. Everything looks perfect at design time. But when I run it on the Fire, all of the numbers in the edit boxes are slightly cut off at the bottom as if they didn't quite fit into the edit boxes.

For a while I tried to make the edit boxes taller, but every time I changed the Height setting, it reverted to what it had been. I thought I had successfully made the edit boxes taller in the style designer. Apparently it reverted again.

It looks to me like the text should fit and so I suspect it might not be a matter of the text being too large for the edit box. Currently my Font is probably default, tahoma. I changed one Edit to Ariel, but they look exactly the same to me.

Currently the text is set to 28 and the height of the edit is 32. I would like to change this to 36. It won't let me change the height of the edit. I have text align set to center for both horizontal and vertical. I tried the other two settings for vertical. One moves the text up and now the top of the numbers are cut off. The other one lowers it and then there is even more of the bottom of the numbers being cut off.

I tried using a smaller font and that does fix it, when I get down to 24. But really I would rather have larger text in taller edit boxes.

How can I …

I'm trying to send the value of an EditText to a PHP file.

I need that value to perform a query, and get data.

I don't understand why the value is not passed.

Can someone help me?

$conn=$dbh->prepare('SELECT * FROM ServiziRistorante WHERE id=:id');

$conn->bindParam(':id', $id, PDO::PARAM_STR);

$conn->execute();

if($conn->rowCount() > 0){
while($row[] = $conn->fetch(PDO :: FETCH_ASSOC)) {

    $tem = $row;

    $json = json_encode($tem);

} 

} else {
 echo "No Results Found.";
}

echo $json;

?>

What would be the suggested methods to input data, via speech recognition, on a generic web page?

I have some web pages, that are not public to anyone, that our quality control department logs their measured data into.  This works great for functionality, when using a keyboard, but it is time consuming to type the data.

Is there a way for a computer, or a handheld device (IOS / Android) to automatically "listen" / all the time?

Is there a way to browse the web solely using speech commands on any piece of hardware?

We have a android NFC payment application where the application reads NFC tags and deducts the fare amounts from passengers.

This applications is used by our customers on android tablets that come quipped with NFC feature. However, lately it has become extremely hard to find off the shelf tablets that have NFC.

I am looking for some direction is what would be best course going forward. We have to integrate the NFC tag reading capability using some kind of NFC dongle or a blue tooth device.  has anyone encountered this problem and is there a solution available?

I have a Droid user on outlook (cloud) with MA.  All his contacts are un-assigned.  They do not show via Blue Tooth in his car (Toyota).   If he puts them in a group they show up just fine.  As soon as outlook does its sync it un-assigns them.  Any suggestions on how to keep them in a group.

I'm looking for software that runs on a Raspberry Pi that completely replaces my car stereo. In other words unlike android auto I don't want something to hookup to my phone or current car stereo. I'd like FM radio (AM radio is optional), a GPS system. Of course playback my downloaded music or off a sd card or usb stick. Other nice to have, dash cam. Blue tooth , wifi etc which comes with the Pi model 3's. As I said a complete replacement not add on for my stereo. I realize I'll have to buy a GPS unit, camera etc. I plan on using the Raspberry Pi 7in touch screen. It will fit in where my old stereo was/is.
I'm assuming I should be using some form of Kodi for the system.

Any help or ideas would be appreciated.

I am attempting to make the migration from traditional cable TV to the internet only.

Netflix gives me lots of choices for TV and movies, which I was not aware of when I started doing research on this topic, so that solves the unified search problem for me.

The only content that I really miss now that I have Netflix for TV shows, is the local nightly news.

Is there any way for me to get this single localized content airing over the internet on any of the network channels (ABC, CBS, NBC, or FOX)?

Assistance is still greatly appreciated.

Say, on the android phone system there is a Google Maps application and this is obviously also available on the Apple phone. Does the Apple phone have any native solution for location sharing ? I'm looking for Live location Sharing with friends,, similar to what is available through the Google Maps App. Please advise detailed steps on how to activate such service on Apple phone. Thanks, Shaun

Hi,

I have a Samsung Galaxy S9 phone.

On this phone is an app that needs to be open in order to get the most out of the app.

Is there a way to have certain apps on this phone open once the phone is powered on and started up?

Thanks,
