How Google Cloud Messaging handles Doze in Android 6.0 Marshmallow

Android 6.0 Marshmallow introduces a new power saving feature called ‘Doze’. A device enters Doze when the user leaves it unplugged and stationary for a period of time and with the screen off. When this happens, the system defers application activity to save power. It will periodically and briefly resume normal operations, called an idle maintenance window, in order to perform app syncing and other pending operations.

If your app uses Google Cloud Messaging (GCM), you will need to take into account the following behaviors for users whose devices are in Doze.

GCM has two priority types for messages, called high priority and normal priority. When using high priority, GCM attempts to deliver messages immediately, waking a device in Doze, as needed. With Android Marshmallow, nothing changes here.

However, when using normal priority (the default priority), there are a number of different behaviors when the device is in Doze, including:

The most important change is that messages will be batched for devices in Doze. When the device enters its idle maintenance window, the batch of messages will be received.
We discard messages whose time_to_live expires while the device is in Doze (including TTL=0).

Despite this, it is recommended that, unless absolutely necessary, you keep your notifications as normal priority ones, as this will minimize battery impact. They will still sync during doze mode as described above, and of course once the device exits Doze.

High priority messages should only be used by applications that need to generate an immediate notification to the end user such as a chat app notification or an incoming phone call.

How ad-free subscriptions could solve Facebook

At the core of Facebook’s “well-being” problem is that its business is directly coupled with total time spent on its apps. The more hours you pass on the social network, the more ads you see and click, the more money it earns. That puts its plan to make using Facebook healthier at odds with its finances, restricting how far it’s willing to go to protect us from the harms of over use. The advertising-supported model comes with some big benefits, though. Facebook CEO Mark Zuckerberg has repeatedly said that “We will always keep Facebook a free service for everyone.” Ads lets Facebook remain free for those who don’t want to pay, and more importantly, for those around the world who couldn’t afford to. Ads pay for Facebook to keep the lights on, research and develop new technologies, and profit handsomely in a way that attracts top talent and further investment. More affluent users with more buying power in markets like the US, UK, and Canada command higher ad prices, effectively

Phoenix OS is (another) Android-as-a-desktop

Google Android may have been developed as a smartphone operating system (and later ported to tablets, TVs, watches, and other platforms), but over the past few years we’ve seen a number of attempts to turn it into a desktop operating system. One of the most successful has been Remix OS , which gives Android a taskbar, start menu, and an excellent window management system. The Remix OS team has also generated a lot of buzz over the past year, and this week the operating system gained a lot of new alpha testers thanks to a downloadable version of Remix OS that you can run on many recent desktop or notebook computers. But Remix OS isn’t the only game in town. Phoenix OS is another Android-as-desktop operating system, and while it’s still pretty rough around the edges, there are a few features that could make it a better option for some testers. Some background I first discovered Phoenix OS from a post in the Remix OS Google Group , although I’ve also found mentions of th

South Korea aims for startup gold

Back in 2011, when South Korea won its longshot bid to host the 2018 Winter Olympics, the country wasn’t widely recognized as a destination for ski and snow lovers. It wasn’t considered much of a tech startup hub either. Fast forward seven years and a lot has changed. For the next 10 days, the eyes of the world will be on the snowy slopes of PyeongChang. Meanwhile, a couple of hours away in Seoul, a burgeoning startup scene is seeing investments multiply, generating exits and even creating a unicorn or two. While South Korea doesn’t get a perfect score as a startup innovation hub, it has established itself as a serious contender. More than half a billion dollars annually has gone to seed through late-stage funding rounds for the past few years. During that time, at least two companies, e-commerce company Coupang and mobile-focused content and commerce company Yello Mobile, have established multi-billion-dollar valuations. To provide a broader picture of how South Korea stacks

What will a driverless future actually look like?

There is a growing consensus that autonomous vehicles (AVs) will soon be a reality. The debate today centers not on whether, but how soon, AVs will be commonplace on our roads. But for all the buzz surrounding AVs, many details about what a driverless future will look like remain unclear. Which business models will work best for the commercialization of AVs? Which AV usage models will be most appealing for consumers? Which companies are best positioned to win in this new market? These are big questions, and no certain answers can be given at this stage. Nonetheless, it is valuable to reflect, in a concrete way, on how this transformative technology might develop. This article will present some conjectures. The end of private car ownership? At a high level, two possible paradigms seem most likely for how society will use AVs. The first is private AV ownership. Under this model, individuals or families would continue to own their own vehicles and use them to get around. As
