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++).

I need to create several hundred email addresses. I would prefer to create Google accounts and use the Gmail addresses. These need to be free accounts and not G Suite for Business accounts.

These are not for spamming or scamming. Rather, we are a non-profit organization configuring several hundred Kindle devices for students in remote areas around the world. To do this, we need to create hundreds of Amazon accounts using hundreds of unique email addresses. While the creation of the Amazon accounts will be laborious, I think I can do it. We will configure one device per Amazon account, and each account will purchase 60 books. I would like to use Gmail addresses/Google accounts for email, as I am not yet sure if we will be using Kindle, Kindle Fire, or the Kindle app on an Android tablet. If we go with the app, then we will need to use Google Play, which will require a Google Account.

Once each device is loaded and configured, the email/Gmail/Google account as well as the Amazon account (and loaded device) will be handed over to the end user who will take ownership of the Amazon and Google account. We will be providing these as gifts; we are not reselling accounts and devices.

What is the best way to create many Google accounts without raising red flags? In the end, we need around 250 accounts. We don't need to create them all at once.

There are around 40,000 photos on my Whatapps image folder. When I plug my android phone and view the folder in my Window 10. It always can't lookup the files successfully.

Is there any way to view those image files ?

Dear Experts,

My company has 9 Samsung Tablet A, 8.0".  The Android version is 8.1.0.  One of the users deleted a picture from the gallery on one of the tablets.  He called me to see if I could retrieve it.  I understand that the Samsung tablets do not have a trash can; therefore, the picture is permanently deleted; however, I understand that there is some Android recovery software on the market that will recovery deleted files from tablets; therefore, I checked into some Android recovery software.  Even though most of the recovery software says it will recover from your phone, it also appears to work on your tablet as well.  I tried one piece of software, Coolmuster's Lab.Fone for Android; however, it appeared to not even look at the files deleted from the gallery.

So, my question for help is:  In your experience, what is the best software (it doesn't have to be free) to recover deleted files from a Samsung tablet's gallery?


Thank you,

We have a proprietary and patented video processing software that we license to others and we use on our own sites.  A couple or our sites/apps get approximately 3 million page views per month and are on the verge of profit.  The plan is to expand/scale the sites we own in the next six to twelve months.  This scaling presents us with a opportunity to update everything in our system.  Even though they were launched only a few years ago, so much has changed that we are forced to look at the whole architecture from hosting to platforms and development environments, etc.  We are truly a garage startup and have to make the most of limited resources while trying to present a high quality solution.  It is difficult and stressful.  We cannot afford to get this wrong thus my appeal to the many experts here. We are starting with a clean slate and very much need to hear from experienced professionals to help us put together the best possible system from the top down.

Server/website -  up to now we have used dedicated hosting.  It appears that VM is now a good and much less expensive option.  I am OK with that.  In speaking with other insiders it seems that more and more people are going toward utilizing Azure or Amazon for hosting.  We do have licensees in Europe who must be served by hardware in Europe due to latency issues.   I think Azure or other allows a much quicker provisioning of another instance in whatever geographical area needed, that we can then customize …

Today, I had an interesting experience. I had left my phone plugged-in and attached to the windshield of my car while I was in a gymnasium at my church.

I noticed some kids that didn't look like the usual crowd gathering inside the gym but didn't really think anything of it until I got back outside to my car.

I received a message that the firmware on my phone had been flashed with an unsupported version.

The message soon went away, and the phone proceeded through some significant updating.  It had a percentage in the middle of a rotating wheel with dots around the outside of it.

Since my phone is back to normal now, nothing appears to be wrong, but I am still concerned none-the-less.

It is a Galaxy Note 8.

I need some tips on how to check to see if I have the correct firmware for my device since I am no longer getting any messages to the contrary?

I've been having trouble returning an Id from my listview to use for deleting a record.  I have a SQLite table that feeds a list adapter.  Here is my class:
public class EOMCountsheet
    {        
        [PrimaryKey, AutoIncrement, Column("-id")]
        public int Id { get; set; }
        [MaxLength(6)]
        public string Location { get; set; }
        public int InventoryCount { get; set; }
        public string Part { get; set; }
        public string UserID { get; set; }
        public string UniqueStamp { get; set; }
    }

Here is the Adapter and _listView1.ItemClick:
            string path = Path.Combine(System.Environment.GetFolderPath(System.Environment.SpecialFolder.Personal), "CountSheet.db3");
            var tablelistout = new SQLiteConnection(path);
            var list = tablelistout.Table<EOMCountsheet>().OrderByDescending(t => t.Id).ToList();
            var data = new List<string>();

            foreach (var listing in list)
            {
                data.Add(listing.Id + "  " + listing.Part + " - " + listing.InventoryCount);
            }

            ArrayAdapter<String> listAdapter = new ArrayAdapter<String>(Activity, Android.Resource.Layout.SimpleSelectableListItem, data.ToArray());
            listAdapter.NotifyDataSetChanged();

I'm looking for an easy straight forward way to use my Galaxy Note8 to write on my PC's screen, for the purpose of teaching at school.
Instead of walking over to the board all the time to solve equations, I would like to do it using my Samsung Notes on my Note 8.
So I need a fast way to plug my phone to PC in classroom with USB, no WiFi available, and start my hand writing, PC is connected to projector of course!
Note: I'm struggling now with Samsung's Side Sync which doesn't seem to be the answer, it switches between two screens instead of showing them both.

Thanks.

I'm looking for a non-realtime multi-player Chess app for Android. ie one where each player can take their turn at their leisure, so they don't need to be online at the same time.

Can anyone suggest one? Even knowing appropriate words to search for an app that's non-realtime would be helpful, as this doesn't seem to be a feature offered by 2 of the most popular apps I've tried out.

Say, I have installed Skype on an Android Blackberry KEYONE. It has duplicated my Google Contacts, made an additional contact for Skype and many blank Google Contacts.
Is there a way to reverse this?
Is there a way to set up Skype so that it does not interface with my Google Contacts at all? I do not need it to have access to my Google Contacts.

We have xamarin based mobile application and an API which is made in asp.net core hosted in windows azure.

Till last week we have been using an http url for calling the api in the mobile application. for example http://api.xxx.com
Everything was working right.

This week we changed to https://api.xxx.com.
Since then when we build the android app on the actual device we getting this error.

"System.Net.Http.HttpRequestException: An error occurred while sending the request ---> System.Net.WebException: Error: TrustFailure (Authentication failed, see inner exception.) ---> System.Security.Authentication.AuthenticationException: Authentication failed, see inner android native xamarin"

Not sure what is causing this error but till now we did not find a solution

I have 2 Galaxy Note4 : both of them tends to run out of battery
power pretty quickly (the one from Korea stays a bit longer)
despite that I replace with new batteries (merchant claims they're
original).

Then one colleague told me he faced the same issue (esp from
40-50%, it can suddenly go down to 0%) when running more
intensive apps like Waze GPS despite that he replaces the battery.

I then got this high mAH high capacity battery from Amazon:
https://www.amazon.com/Lifespan-6980mAh-Extended-SM-N910A-Smartphone/dp/B07NL42B5Q/ref=sr_1_3?keywords=Note+4+battery&qid=1565667061&s=gateway&sr=8-3
It took longer to charge & last longer too (but at around 30-40%)
or when the phone is on standby over the night for 11 hours, it'll
just go flat the next morning (despite that it was initially at 90%+).
I did set the brightness to almost 0 overnight with "mobile data"
off (but Wifi is On at home) & the "task manager" shows only
Whatsapp & Messages  apps are running overnight.

Is this quick-draining of batteries an issue with the old phone (&
can this be tuned) or there's some apps that can be tuned/removed
to reduce the battery draining.

Or all the batteries I've got so far are not good (which I doubt)??

I am looking to share a phone with a local audience as depicted in the following scenario.

Phone Scenario:
Let's say that I was going to present the following sample slide presentation to a larger audience from my phone, meaning that I was going to pass my phone around the room and allow others to navigate through the following slides as shown here https://shorturl.at/yNOT4.

I don't want the viewers to lose that spot and be forced to hand my phone back to me before it makes it around the room.

How can I accomplish this, ensuring that the slide content is not interrupted by messages or by navigating away from the intended content?

Assistance is greatly appreciated.
