Is there a feature available within a Samsung Galaxy S8 to allow rings and notifications only from certain phone numbers? This feature is available for iPhones and now I'm trying to figure out how to activate this feature on a Samsung Galaxy S8 cell phone

This is a very important feature for me to have while I'm sleeping and only want to be disturbed by certain people.

What are the best apps for having additional phone numbers on a Samsung Galaxy S8 phone besides Google Voice?

I am looking to link another phone number to my Samsung Galaxy S8 cell phone. I already have Google voice installed on this phone and need to add yet another phone number to this phone.

What are the best Android apps for doing this?

I'm going to be starting a project where I need to be able to answer my phone 24 hours a day.

I also need to be able to completely silence all other alerts from my phone so the only times I will be woken up will be if someone calls or texts my Google voice number.

Is there a way to completely turn off new call, email, & text alerts on Samsung Galaxy S8 accept for Google Voice alerts?

I just signed out of a Google Voice account on my Samsung Galaxy S8 phone.

I have logged in with another Google Voice account which is the one I want to have associated with my cell phone.

The problem is that when I make phone calls using my Samsung Galaxy S8 phone the caller ID for the most recent Google Voice account (510-xxx-xxxx) displays instead of the caller ID for the other Google voice account I have switched back to (415-xxx-xxxx).

I also remember that when I have set up Google Voice numbers in the past that these Google Voice numbers have given me the option to fully integrate Google Voice with my Sprint PCS phone (which is what I want to do now). However I am not given this option at this time.

What do I need to do to fix this issue so that the phone number associated with my 415 area code Google voice number will display whenever I make phone calls?

We are moving from Fireeye MTP  to another product, considering Lookout .

Anyone can point me to or share reviews on Lookout?

Also, what are the assessment criteria I have to look out for considering that
our corporate phones (mostly iOS currently) & iPad are managed by
MobileIron MDM?

Email to be used is MI's email+  (not the native built-in email client)

I heard iOS is tailored from FreeBSD so I'm hoping to be able to do something like
"ps -ef |grep email_client_process"
if it's not there, then restart it.

Reason is our MobileIron email+ client kept getting killed by iOS as iOS sees it
as a 3rd party/foreign process.

any chance of doing this on an MDM controlled device?

I recently turned in an iPhone 5 at the end of a project.

This iPhone 5 is now out of state.

1. What does it mean for  "tools:context="com.abc.passingdata.MainActivity"  ? (sample 1)
2. What does it mean for the following XML statement ? For "action", does it refer to the corresponding java class. How does "category" defined in sample 2 ? Any special meaning ? Thx

            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />

Ready to get started with anonymous questions?

It's easy! Check out this step-by-step guide for asking an anonymous question on Experts Exchange.

We send an SMS with a URL (e.g. mydomain.com/whatever)
The custom app "ABC" installed on the phone has "mydomain.com" as "supported links"
Using Android Messages, no problem, it launches ABC.

However using Samsung Messenger or Messages, clicking on the URL just opens the website.
In other words, it ignores the Settings for ABC.

Forcing users to install Android Messages is not an option for us.
What do you suggest?

Hello

I understand with the Samsung S8 that there is the ability to view more than one app on the screen at the same time

Some questions

1. I know Mac can do this, can IOS iPhone and iPad

2. When I try this on a Samsung S8, i always seem to get the Settings as the first app and then any other app as the second. How can I get two real apps to run in multi screen

Last week my Note 2's phone popped up the above message & while this message
is showing up, it won't allow any activity (reading, typing) etc in Whatsapp: it took
more than 15mins & I decided to power cycle it.

Presume its whatsapp messages/content being backup : does it backup to
the microSD card in the phone or to Cloud & how can I restore (ideally selective
restore of selected messages) ?

I'm trying to run commands in command prompt on PC,

npm install -g cordova
cordova platform remove <platform>
cordova platform add <platform>

The NPM part works fine, but when i try to run cordova lines it fails with unknown command cordova. I do have cordova installed since I use it in VS and can deploy to android and ios. I realise I'm somehow missing the path in system path but I cannot find anywhere on the net or computer where the cordova root is. Can anyone help?

Thanks,
Primoz

Hello everyone,

I am trying to build a very simple Android Mp3 Player.

I am preparing the bar that contains "Next song" "Play" "Previous" etc but I am not able to put it in the bottom of the page in a way that can be identical on every device.

I started coding my app from a swiped tab interface (the default one in android) and then added my fragment:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentBottom="true"
        android:orientation="horizontal">

        <ImageButton
            android:id="@+id/previous_button"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@drawable/ic_skip_previous_black_24dp" />

        <LinearLayout
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:background="@drawable/circle"
            android:gravity="center_horizontal|center_vertical">

            <jp.co.recruit_lifestyle.android.widget.PlayPauseButton
                android:id="@+id/play_pause_button"
                android:layout_width="25dp"
                android:layout_height="25dp" />
        </LinearLayout>

I have searched the android developer docs (and made lots of google searches) but I cannot find anything that shows what the code is exactly for turning off the 'Motion Effect' when setting a wallpaper. Apparently I am looking in the wrong directions or just completely missing something... but could someone please show or point in the right direction for how to turn off the 'Motion Effect' when setting the wallpaper from an app?

I see how to do this when manually setting my own wallpaper on my phone using android's ui but I cannot find java code that does the same thing (for example using the WallpaperManager or something similar).  Please see attached image.  Thanks

On Demand Webinar - Networking for the Cloud Era

This webinar discusses:
-Common barriers companies experience when moving to the cloud
-How SD-WAN changes the way we look at networks
-Best practices customers should employ moving forward with cloud migration
-What happens behind the scenes of SteelConnect’s one-click button

I'm new to both VS, cordova and everything else in between (but long time programmer).

When trying to install cordova plugins via config.xml, choosing from local path, it appears to fail to install or crash if the directories have spaces in them or if any of the variables have spaces in them (eg. a facebook plugin asked for a appname and if i put in two words it would fail).

Am i missing something or do these plugins still follow dos standards where spaces and periods are not allowed and should be only 8 characters long?

Hello

Imagine this scenario -

A user walks into one of our support centres. The user has one of our mobile apps installed on their device. A beacon within the support centre is set to transmit an alert to a support tech when it detects the presence of our mobile app close to it. The beacon sends information on the user to the support tech who is able to identify them.

Possible?

We are looking at a couple of applications for voice recording on corporate owned mobile devices. We want these to be hidden, such that the user can't delete these. Is this possible on iOS / Android? I'm not sure what the correct term is but I've chosen 'headless'.

Going one step further, is it possible to prevent these being stopped from running on iOS/Android?

What is the best apps where I can use my computer to text other phone and receive text and pictures. I know some of them you have to know the service of the phone that you contacting so it can use SMS. I don’t want to have to use that but to go through my wifi. Also, I don’t want to use Google because I tried that before and created a separate account but it still integrated with my other Google account.
