Applications appearing as blank white screens in the list of recent applications in landscape orientation

I've noticed a strange behavior on the screen of recent apps on Android that I can not find any explanation. When I open applications on a phone in landscape mode and I switch to the screen of recent applications, all I see is a white square for this application, no thumbnail preview.

Here's what it looks like on a OnePlus 6 when I open Chrome in portrait mode and I open the screen for recent apps.

But when I open Chrome in Landscape mode and then I switch to the screen of recent applications, I get this message.

And similar behavior on a pixel 3:

Open Chrome in portrait mode and switch to recent apps

Opening Chrome in landscape mode and switching to recent applications

If I leave some time to Pixel 3, it will eventually generate a vignette for the Landscape app, but about half the time, it seems crushed in this way, and the other half does not match what was actually displayed on the screen.

My question is this: why does Android seem to have trouble generating preview thumbnails in landscape mode for the screen of recent applications? Has anyone else ever experienced this behavior or found a solution?

Web applications – Web technologies involved in streaming videos on demand, from the remaining API to the simple page application

I plan to create a website for my physics teacher, where he will be able to download his lectures as videos that can be viewed on demand by students. The web application will have a client-server architecture with the Python Flask structure for the remaining API and an Elm SPA as a client. As you can imagine, this API will have a lot of CRUD features regarding resources such as user accounts, payments, and so on.

What concerns me, though, is the video-on-demand portion. In which format should I broadcast the videos and how will I proceed on a resting point?

I'm comfortable with CRUD, but it's an overwhelming task for me because I'm new to the streaming space. I need pointers and help to put me on the right track. Any orientation and additional resources will be appreciated.

antivirus – FYP Ideas in Auto Learning Applications in the Field of Cybersecurity

I am a computer engineering student aspiring to a career in the field of cybersecurity. I have experience in the fields of web application security, memory and forensics on networks. I would like to have some suggestions for my five-year plan in the field of cyber-security + machine-learning. I am interested in getting different ideas or any specific idea regarding the sub topics above.

Default Applications – Opens links to a particular domain with a particular application

I use a default browser, but I want links to certain domains to be open by default with another browser. For example, if an application has a button that opens a website, it normally opens in the default browser. This is fine in most cases, but with a few exceptions, I would like to change the browser in which the site opens.

Is it possible to define "rules" for the default application by domain?

Applications – When access to notifications is not available on your phone, is it possible to run third-party apps / in the background?

I have installed (…) (device monitoring application) on a phone.
During installation, the target phone displays an error saying "Access Notifucation – this feature is not available on this device".

Since my monitoring application does not work properly! Or does not work at all.

Question: I understand that (…) is a background / third-party application – Is it possible to run a third-party application on a device where the notofication access feature is unavailable?

Managing multiple applications behind a single connection

UX Community –

This question concerns the choice of the destination by the user during / after the connection.

Suppose we have an account that can handle multiple applications, A, B, and C. Users of one app are not necessarily the users of the others. However, there may be some overlap between app A and app C, and app A and app B.

There is no global navigation for these applications when connected, no main dashboard and the user interfaces of A are quite different from B and C (A is a legacy service). So, currently, a user must log in to A and must search for a folder to access C, which is a new offer.

How would you manage to direct users to the correct destination when connecting? Ideally, App C users never need to access the application A (although there are many buttons that administrators can activate in A and change the application C)

In my opinion, there are several approaches.

  • Each service has its own dedicated login page, and they never touch each other. Users of multiple applications must use two different login pages or browse the deep (possibly) folder structure of A to access the C application.

  • A choice of user is offered when connecting (if he has multiple applications) to which destination he wants to go. It's almost like choosing a role for their work, but of course we also have the roles designation in the application. The two wireframes below show some options for this.

Our ideal solution would evolve with other potential applications in the future without much design change. Services should end up feeling connected within a suite. Few rigorous requirements have yet been listed, so I use this opportunity to discuss the best understanding of our goals as a group.

My research has mainly resulted in several methods of connection (single sign-on, etc.), but not to multiple connection destinations or choice of applications. Are there any good examples of this type of connection model? Any other considerations I may miss? Am I thinking about it?

Does Gmail need attention? – Exchange of web applications

I open Gmail, I see my emails labeled Category/Primary in my main inbox, loading is still in progress, after a few seconds, it stops loading and suddenly a new message appears at the top of the list of main tabs: A message titled Category/Forum I check the labels on this message, it does not have Category/Primary label, he did not play, I turned off Include starred in Primary.

I refresh the page, the same thing happens again: the message is not there during loading (the cone turns) and after a few seconds, it is added at the top of the list.

The most annoying thing about this is that I even see a notification on my Android about this message, my Android only displays email notifications that I get in my main tab.

What is this message? If it is not labeled primary, why is it in the primary tab? If it's marked primary why do not I see this label on it? Why is not it in the first rendering of the message list and it suddenly appears after a few seconds? Why does this happen only for certain messages from Jira de Qt and Kubernetes Github? I get a lot of notifications from Github and Jira, but messages from only some threads end up like that, not even all messages from these threads.

Does Gmail need my attention? Do I reward Gmail every time it works properly and punish it whenever it spoils my labels?

laravel – Windows server configuration (PHP, wamp) for different subdomain applications

I develop PHP / Laravel applications and I have to configure a local server to access different directories of the same domain, as in the examples below:

domain.com/aplicacao01 -> Access an application x

domain.com/application02 -> Access an application y

Since I have no experience of configuring the Windows server or the freedom to configure to my liking, I have to adapt to what has been provided:

Windows server, running wamp with different directories for each laravel application.

A light?

Force stop bloatware applications on an Android phone

I do not use Facebook and I do not intend to do it. Can I force the stop on an Android phone (LG Pen 4) without destabilizing anything? I have installed WhatsApp, which I know is the property of Facebook but I think (hopefully) operate independently and which, hopefully, would not be affected by the shutdown of Facebook.

applications – How can I open an offline website on Android?

I have a directory with .html files, some .jpgs, a index.html file, and some other stuff. If I drag the index.html in chrome (or from other browsers) on my desktop, this static / offline website displays in the browser and I can navigate the site without problems.

When I go to the same directory in Android Pie and open it index.html file in Android-Chrome I get the error "the file was not found". I have tried other Android browsers with the same result.

How can I open a simple offline static HTML website on Android? Is there a specific application or browser that I need to use?
