How To Change When Messages Expire On Snapchat

Snapchat is an app built on the whole concept of missing out if you don’t engage it immediately. If you don’t see a message within a limited time frame, it’s gone. All your friends will be talking about it and you’ll be out of the loop. It’s either a limited time frame or the one-view policy that chat messages have. Snapchat is changing things a bit with chat messages. Users now have the option to allow the messages to have a one-time view limit or to allow the message to be viewed multiple times for 24 hours. Here’s how you can choose when messages expire on Snapchat.

Expire Message On Snapchat

This is a new feature available on both iOS and Android. This deals with the private chat messages that are exchanged between users. This is set on a per-person basis which means that you can allow some friends to view a message only once while allowing others to view it as many times as you want for 24 hours.

Open Snapchat and tap the chat button at the bottom left of your screen. Select a conversation from the list of conversations or start a new thread with a contact. Tap the hamburger icon at the top left and and on the chat settings screen, tap the Delete Chats option.

A menu will open with two options; After Viewing, and 24 hours after viewing. By default, the expiry for all conversations is set to After Viewing. The 24 hour option has to be changed manually.

The 24 hour viewing period for a message starts after it has been viewed once. If a message hasn’t been viewed, you can always delete it. It’s not like posting to your story. Anything you post to your story expires 24 hours after you post it regardless of who has, and who hasn’t seen it. With chat messages, an unread message will not start the 24 hour countdown. Once a user views the message that you’ve sent, the 24 hour period will begin counting down.

The messages expire individually which means each message sent within a conversation thread will have its own expiry time based on when it was first seen. If you sent a message at 8 in the morning and another message at 8 in the evening, assuming they were both viewed immediately after being sent, they will have different expiry times. If both messages were viewed at the same time though, they will have the same expiry time, give or take a few seconds.

When you change the message expiry time, your contact is alerted to the change.

How To Set Up Android Development Tools On Linux

Increasingly, Android app development on Linux is growing. The main reason behind this is that the Linux platform makes it super easy to get a full developer workstation going (compared to other platforms.) Development is one of Linux’s strong suits, so naturally, setting up Android development tools on Linux is easy.

Android Development Tools On Linux

Android Studio is Google’s complete development suite for creating software on the Android platform. It comes with dozens of tools, emulation setup, and code to work with.

Note: Before attempting to install this software, please install Java. Failing to install Java will make Android Studio unusable.

Install Java

Getting Java for Linux differs, depending on the operating system you’re using. Generally, most Linux distributions have excellent support for OpenJDK. It’s an open implementation of the Java tools. It’s best to go this route, and most developers won’t notice the difference. Follow the instructions below to get Java working on your distribution.

Note: aside from OpenJDK, you may need to install other dependencies to run Android Studio on your Linux PC. For more information, check out the official guide page for Linux.


Ubuntu users have easy access to OpenJDK. As of Ubuntu version 18.04, OpenJDK 11 is available. To install it, open up a terminal and use the Apt package management tool to get it going.

sudo apt install openjdk-11-jdk

Need more than just the standard OpenJDK 11 package? Check out these other packages.


Debian is a Linux distribution that focuses primarily on solid, stable software. It is because of this, the absolute latest version of OpenJDK is hard to get ahold of (version 11). Still, it is possible to get version 8, which is functional.

Note: if you absolutely have to have version 11, consider upgrading Debian from “Stable” to “Testing,” or at the very least using backports.

sudo apt-get install openjdk-8-jdk

Alternatively, install all Java JDK 10 stuff into Debian with:

sudo apt-get install openjdk-8-*

Arch Linux

Arch Linux is bleeding edge Linux, so there’s no issue getting a fairly current version of OpenJDK working correctly. Unfortunately, despite how recent Arch is, there’s currently no builds of version 11. Still, users have access to OpenJDK 10, which is fairly new.

To install the software, open up a terminal and use the Pacman packaging tool to get it running.

sudo pacman -S jdk10-openjdk


Fedora Linux has version 10 of OpenJDK, which should be enough to run and develop on Android Studio. To install it, use the DNF package management tool in the terminal.

sudo dnf install java-openjdk -y


Depending on what version of OpenSUSE you use, your packages are either very new or very old. For this reason, getting one version of OpenJDK working across all versions of SUSE is a bit tricky.

To get OpenJDK working, head over to the download page for OpenSUSE. On the download page, select the version of OpenJDK you’d like, then click the “install” button to start the installation process.

Generic Linux

Many Linux distributions (even the obscure ones) use OpenJDK because it’s safe to include in software repositories. As a result, installing OpenJDK is incredibly easy. To get it working open up a terminal and search your package manager for “OpenJDK”. Alternatively, download it from the official website.

Download Android Studio

Unfortunately, Android Studio doesn’t have a downloadable binary package. Instead, users looking to use the development suite on Linux will need to download a compressed archive file.

Head over to the official download page and click on the Linux download link. Read through the EULA and check the box to accept the agreement to start the download. When the download finishes, open up a terminal window and use the Unzip tool extract Android Studio.

cd ~/Downloads

unzip android-studio-ide-*

Using the CD command, move the terminal into the bin subfolder.

cd android-studio/bin

Install Android Studio

Start the Android Studio installation tool with:


In the Android Studio Wizard, select the “Standard” option. When the Android Studio Wizard finishes the installation process, click the “Start a new Android Studio” option to begin development.

Android Command-line Tools

Aside from Android Studio, there are other important development tools for Linux that you may want to install. Specifically, command-line tools that allow users to interact with devices on Linux. Thankfully, installing these command-line tools isn’t as tedious as Android Studio.

To get the Android command-line tools working on Linux, follow the instructions below that match your Linux OS.


sudo apt install android-tools


sudo apt-get install android-tools

Arch Linux

sudo pacman -S android-tools


sudo dnf install android-tools -y


sudo zypper install android-tools

Generic Linux

Need the Android command-line tools but can’t find them in your Linux distribution’s software repository? Google has a standalone download for those that need it. Head over to the official download page, and scroll down to “command line” to get it.

How To Make Group Calls On Whatsapp

Whatsapp has a new feature; group calls. It works with both video and voice calls. You can call up to four people in one group call. The group call feature isn’t the most obvious so you might still be wondering if it’s rolled out to everyone yet or not. It has and if you know where to look, you can make group calls on Whatsapp right now.

Update the app on your phone before you try a Whatsapp call. Since your recipients will only be answering the call and not initiating the group call, they don’t necessarily need to be running the latest version of the app.

Group Calls On Whatsapp

Open a conversation thread or, go to the Call tab. From the Call tab, select a contact you want to call. If you’re in a chat thread, tap the call button. You can choose either a video or audio call.

When the call is in progress, look at the top right corner and you will see a greyed out option for adding a second person to the call. Wait until the person you called answers, and then the add person button will be active. Tap it and select a contact from your contacts list to add the second, third, and fourth person.

The limit is four people so where Whatsapp is following Instagram and Snapchat’s trajectory in terms of feature development it’s not exactly competing with the two apps. Instagram and Snapchat have group calls for more social communication and where Whatsapp is a social app it’s not exactly in the same category. Whatsapp is best grouped with apps like Facebook Messenger and that makes the four people in a group call a reasonable limit.

It goes without saying that in a group call, everyone can see everyone though when you’re adding a second person to a call, they may not necessarily be told they’re being invited to a group call so give them a heads up before you make it.

Whatsapp is one of the most popular messaging apps on both iOS and Android. Since it’s highly unlikely that Facetime will ever make it to Android, this feature is pretty great if the call quality turns out to be good. Four is a reasonably good number of people for a group call so it will meet most needs. More importantly, you can answer calls from the web and desktop version which means you can call people on their computers too.

How To Turn Off Instagram Live Notifications

iOS and Android both allow users to enable, or disable notifications from an app, at will. For each app, there’s a dedicated On/Off switch that allows users to enable or disable notifications for apps selectively. While you can disable notifications for some apps, and enable them for others you never have the option to choose which notifications an app can send you. For example, if you’ve enabled notifications for a game on your phone then you get every single notification from it including new challenges, friend requests, expiring offers, etc. Instagram is no different however, the app is unique in that it gives you an incredible amount of control over which activities you get a notification for and that’s why you can turn off Instagram Live notifications.

Instagram Live Notifications

Open the Instagram app on your iPhone or Android phone. Tap the profile tab, and on the profile tab tap the gear button. This will take you to Instagram’s settings. On the Settings screen, scroll down to the Notifications section, and tap on Push Notifications. You will find this screen is particularly long and with a customization option for every type of Instagram activity. Scroll down to the Live Videos section. Select the ‘Off’ option to turn off Instagram live notifications.

Once you’ve turned this option off, only the notifications that tell you an account you follow is live will be disabled. Every other notification that you’ve enabled will continue to arrive on your device.

While you’re at it, you can go through the rest of the options on this screen and disable every single Instagram alert that annoys you. These settings are device specific so if you use Instagram on more than one device, you will need to change your settings on each one.

There appears to be one shortcoming with this; you cannot selectively subscribe to Instagram live notifications for certain accounts. If you turn off story notifications, you still have the option to enable a story or post alert for select accounts. This same option isn’t available for Instagram live videos. You can try subscribing to post notifications for an account and maybe they will include a notification for when the account goes live but that’s highly unlikely.

One thing is worth appreciating here and that’s how much control Instagram gives its users over their notifications. You’d be hard pressed to find any app that gives as much control. Even if you’re an Android phone user with a rooted phone, you can’t get this level of control over your notifications from a single app.

How To Use Harry Potter Bitmoji Lens On Snapchat

Who would’ve thought Harry Potter would still be relevant after 20 years but it is. The franchise is still alive with at least six more prequels to come so it’s only fit that Snapchat embrace it. Snapchat owns Bitmoji and it uses the avatars to help its users engage more creatively with their friends. There’s a new Harry Potter bitmoji lens that you can add to your snaps. Here’s how to use the new Harry Potter Bitmoji lens on Snapchat.

Harry Potter Bitmoji Lens

You must have Bitmoji configured with and connected with your Snapchat account. If you don’t have Bitmoji set up, take care of that first. Once you’re done, open the Snapchat app and tap anywhere on the camera view finder screen. This will load the lenses drawer.

Look for the lens with HP in the thumbnail. It might take a few seconds to load. If you see the Tap to retry error and the lens refuses to load, try this fix for it. That’s about it.

The Harry Potter Bitmoji lens is animated and features your Bitmoji avatar reenacting the first Quidditch match that Harry ever played. Specifically, it’s you accidentally swallowing and then coughing up the snitch. You have, of course, been sorted into Gryffindor.

This lens doesn’t appear to be regionally restricted though if you can’t see it in the lens drawer, try using a VPN service that lets you fake your location to USA or UK, and then see if you can access it. It should appear regardless if you’ve just created and connected a Bitmoji avatar or if you’ve had one for ages.

While the lens doesn’t appear to be regionally restricted, it will eventually disappear like all lenses do. This lens likely marks July 31 which is the fictional lead character’s birthday but it may stick around or more variants of it might appear in the coming months since a new movie set in the Harry Potter universe is set to be released in November this year and Snapchat will most likely commemorate it.

Although this lens is animated, you can still use it on a photo. The photo will only feature an instance of the entire animation i.e., the point where you tapped the capture button. To record the entire animation with whatever background you’re pointing it at, tap and hold the capture button and let the animation run its full length. You can stack other filters on top of the Bitmoji if you want.
