Smartphone Programming

Smartphones run using a variety of operating systems -- Android, iOS and Windows Mobile most commonly -- and an even wider variety of programming languages, including Objective-C, Java, Visual C#, C++ and .NET, not to mention HTML5 and JavaScript, and cross-platform frameworks such as PhoneGap.

Looking for a better security solution for home directory listing buzz in.  
Due to the increase mail package thefts, HOA proposed to completely remove remote buzz in option.  Currently visitors dialing the code downstairs, call comes to resident's cell phone,  and by pushing '9' the door unlocks;  If we remove that option the resident has to go downstairs to open the door to the visitor. Definitely inconvenient option.  But could be safe. Recently we even noticed the food delivery guys stealing packages on the way out.

My idea to improve it is to add a small cam downstairs.  When someone dialing in the call comes to resident's smartphone.  Resident immediately see shows coming in and make a decision to buzz person in or not.   Can this be implemented for a building of 50 units?  

Any ideas appreciated.   Thanks!!

i use aws-sdk for javascript to give user choice to enable/disable 2 factor auth for login. i have 2 issues: UI is capturing user phone and updates cognito phone_number attribute. (updateUserAttributes) First issue is with this stage, it updates the number but returns empty object instead of

{
    "CodeDeliveryDetailsList": [ 
    { 
        "AttributeName": "string",
        "DeliveryMedium": "string",
        "Destination": "string"
    }
    ]
}

Open in new window

Second, i am trying to send user a verification code with getAttributeVerificationCode with the following payload:

const params = { 
  AccessToken: auth.accessToken,    
  AttributeName: 'phone_number'
}

Open in new window

and i am getting "CustomMessage failed with error Cannot read property identity of undefined" error. Any ideas?

Thanks

https://www.experts-exchange.com/questions/29108461/Peel-Smart-Remote-app-kept-self-reinstall-back.html

Refer to above EE post which is not resolved.

I bought a used Note4 & since receiving it, there's this "Smart Peel remote"
app in it which I've uninstalled it (via PlayStore) : however, the next day,
this app will pop up & when I go to PlayStore, could see that it's installed.

Each time after clicking "Uninstall" for this app in PlayStore, the "Uninstall"
button will turn to "Update" button.

What must I do so that this app doesn't come back (disruptive pop-ups)
again?  

The earlier expert suggest disabling it but how is this done?

Is there any way of bringing up or displaying the iPhone notifications screen (that appears on your iPhone with all of your latest email notifications, Experts Exchange alerts, texts, and other alerts) when you haven't used your iPhone for a while?

For example, I always use my iPhone alarm to wake me up in the morning.

When the alarm goes off I will unlock my iPhone and then turn off all of the iPhone alarms.

Then I will want to go back and view the main notifications screen that contains all of the alerts I have described above (instead of having to go to all of my different email accounts, Experts Exchange app, texts, etc.)

How can I go back to this main notification screen?

I am looking for a lock that runs on batteries and connects to wifi, not Bluetooth for controlled entry access via my smartphone.  It needs to work outside and will be used to control access to a gate.

Assistance is greatly appreciated.

I wonder if this combination using the relay solution is reasonable?

I have an activity where the user can update some data related to his profile (for example, his name) and he can also upload a new profile image.

After the update operation, the user is redirected to a new activity. The problem is that when the user comes back to his profile activity, the showed image is still the old one and not the new one while the name updated correctly.

In order to see the new profile image, the user needs to close the app and open is again.

How can I solve this problem? I use a function updateInfo(), but it seems to not work as I would like.

Can you help me, please?

public class ProfileActivity extends BaseActivity implements ProfileView {

    @BindView(R.id.avatar)
    ImageView p_avatar;
    @BindView(R.id.ib_back)
    ImageButton ibBack;
    @BindView(R.id.txt_title)
    TextView txtTitle;

    EditText etEmail;

    Button btnUpdate;
    @BindView(R.id.txt_logout)
    TextView txtLogout;
    @BindView(R.id.ll_main)
    LinearLayout llMain;

I currently upload finish line pictures from races I time to Google + and share the gallery with race finishers so they can find their picture.  I would like to take that a step further and share each finishers individual picture with them.  I believe Google Vision has the technology to do that...albeit for a cost...by pairing participant bib number with bib in the image.  Is anyone familiar enough with this api to give me some direction as to how to do this?  Also, any idea how this product is priced?

I would like the best way to text from a desktop or laptop PC without knowing the carrier?
There are a few ways to send a text message from any PC but you have to know the person's smartphone carrier.
Then you create an email to the person's cell phone number followed by "@" and the carrier's domain.
But unlike a cell phone, there is no need to lookup the carrier.
I have about 180 physicians with their independently owned smartphones, and I would like to send a text to all of them or a small fraction of them.   I would like to do this from Windows 7, or 8 or 10.
Thank you.

Does the iPhone X have a delete button?

While typing, editing, or modifying emails or texts I sometimes find the need to delete letters or words that are in front of the cursor rather than behind the cursor.

So what do I need to do so I can delete these characters in front of where the cursor is currently located?

I have a new Samsung Galaxy S9 which replaces a Samsung Galaxy S6 and I have two issues which are probably connected:

a) I cannot use the App "Wifi File Transfer Pro" - when I launch the App on the phone it gives an IP address to enter into my browser on the PC, but when I enter this address it will not bring up the page - the connection eventually times out; on the Galaxy S6 this works perfectly

b) I have an app I have written in Java which has components running on the phone and my PC, which I use for transferring various files between the phone and my PC - again this has worked perfectly for many years on the Galaxy S6, but on the S9 it fails to connect:  the phone component successfully wakes up the PC component which does its thing and then tries to connect to send the result, but the java command connection=new Socket(host, PORT) times out with the error message "java.net.ConnectionException: Connection timed out: connect"

It looks like a firewall issue, but it's not the firewall on my PC since I've tried disabling that temporarily.   It may be a firewall issue on the Samsung S9 but I can't see how to configure that.   I've tried tweaking the Setting "Phone visibility" but that doesn't seem to solve the issue.

Any thoughts?

I have a Samsung Galaxy S9+.
Android Version: 8.0.0

I recently put a micro SD card in it and moved many apps to it.  One of them was Bejeweled Classic by Electronic Arts.  Later I noticed that the icon for it was missing, so I went to download/install it again.  When that happened I got a strange error message: "You cannot install this app because another user has already installed an incompatible version on this device"

NOTE: I cannot find the app on my Installed Applications list.

You cannot install this app because another user has already installed an incompatible version on this device
In the link above someone wrote:
What worked for me was: adb shell pm uninstall com.packagename

I have a Terminal Emulator to try that command, I just need to know the exact packagename.

Question: How do I get a listing of package names in the Terminal Emulator?

I have an off-brand Android phone (Alcatel) using Tracfone as my service provider.  For the last couple of weeks I have been having authentication problems after a Norton alert that "my connection was compromised".  I checked all of the router settings, rebooted the phone and now can no longer connect the phone to my home wi-fi network.  I just get the message "Authentication Problem" after an attempt to connect.  I have restarted the phone numerous times, I have rebooted the router a couple of times, and I have Forgotten the connection and re-added it as a new connection numerous times, but it will not connect properly.

My two daughters have exactly the same phone, and they can connect without a problem.

I can connect my phone to the wireless network at work without a problem.

Short of resetting the phone to its factory defaults, is there anything I can try to resolve this?

Anyone knows if there is a way to change a hostname in Polycom SoundStation 7000?   So it would broadcast an actual hostname instead of the make/model name.

I noticed usually  at night (though I'm uncertain at time), my Note4 (which I bought as
a used device) will go into 'silent mode' ie when new Whatsapp/SMS comes, it is quiet
despite that on some crucial Whatsapp group, I set 'Custom notifications" to alert
with sounds (as I am on-call 24x7).

I will notice that following will become disabled (ie at the lowest/minimum setting)
& after enabling it back, it will go back again & again (with each day) without
intervention from me.
  Settings => Sounds & Notifications => Notifications

When new Whatsapp comes, the pop-up still appear tho
(this is a setting under  Custom Notifications)

When I first got the device from the seller, there's a pop-up saying "Good Night,
do you want to silent your phone" which I will cancel but I don't see this pop-up
anymore the last 2 weeks.

What can I do to disable this 'auto-silent' mode which doesn't reverse itself
even day breaks (it's morning)?
