How to Get Lock Screen Widgets on Android

Linkpiz.com0 CommentsTECHNOLOGYANDROID, TECHNOLOGY

Android actually supported lock screen widgets long before the iPhone did. It was officially added way back in 2012 with .

What is the new language to replace PHP? If someone were to make a social networking site like Facebook, what language would you recommend to them, taking into consideration the few million people on at any single given time, speed, efficiency, etc.?

PHP is dying, Java is dying, C# is dying, SQL is dying, Javascript is dying, C is dying. And yet each one of these has probably more currently-ongoing projects than all others combined. Yes, things that have been supplanted by other things tend to slowly fade out but it’s a very slow fade and it doesn’t mean that they’re bad. (Edit: So many people seem to be reading the first paragraph and completely missing the point so I’ll just say it very explicitly. Talking about a programming language dying is pointless. Now let’s get back to the interesting part of the question.)…

Samsung revealed earlier this week that Google Assistant was finally rolling out to the Galaxy Watch 4, which has only had Samsung’s Bixby virtual assistant since the watch was released last year. The good news is that it’s showing up on watches automatically without the need to do anything — in my case, the Assistant icon appeared at the bottom of my watch’s app list, and tapping it started the setup process. If you don’t see Google Assistant yet, Droid Life pointed out you can force the installation by for “Google Assistant for wearables,” and then choosing your watch as…

Linkpiz.com0 CommentsTECHNOLOGYANDROID, TECHNOLOGY

I’ve been using for over a decade, but I recently started using an iPhone full-time. The notifications situation is one area that I have a lot of thoughts about. Android’s notification system has more or less been the same since the beginning, yet I still think it’s better. Lock Screen vs. Notification Center Let’s start things off with perhaps the most frustrating area of iPhone notifications. Not including home screen badges, there are two places where notifications appear: the and the . The lock screen and Notification Center are treated as completely separate things.

iPhone Home Screen Essentials What will we need to replicate the iconic iPhone home screen? First and foremost, it’s the icons—they all have the same rounded-square shape.
