Google Play Services 8.1 SDK ships with new app invites, permissions, Player Stats API

Google has rolled out a series of updates for Google Play and Android 6.0 Marshmallow today aimed at giving better support for developers. The company announced that Marshmallow now has a new permissions model aimed at improving the way app installs and updates are handled. Additionally, Google Play services 8.1 offers support runtime permissions, a new Play Games Player Stats API, and more.

Within Google’s newest mobile operating system version, a new app permissions model promises to let developers offer more control to the users. Not only can the app declare the permissions it’s going to need, but permissions will be divided into groups based on their functionality, making the organization easier. Marshmallow also includes limits on how permissioning is handled at install time — users won’t be prompted to grant permission to some apps because of the nature of these services, such as alarm clock or Internet apps.

Developers interested in tapping into the updated permission model can view more information here. Google cautions that during the preview period, not all of its core apps will have fully implemented this new model.

Besides Android 6.0 Marshmallow, Google Play services has received some updates. The completed rollout of version 8.1 now allows developers to customize the email invitation with a custom image and a call-to-action button. The idea is that by giving more control to developers, more engagement and conversions will happen.

Game developers will be interested in the new Play Games Player Stats API, which will let developers better tailor the user experience to specific segments of players. In an example, Google said that the most valuable players could be rewarded with a special welcome back message when returning to the game.

For those developers using Google Nearby, the company has added a feature that gives apps the ability to receive a callback when an active Nearby publish or subscribe expires. Google Nearby lets apps communicate with nearby devices, and traditionally it would hog up resources. But this update claims to improve accuracy and make it easy to enable apps across devices to talk to one another.

This is the first update to Google Play services since last month, when new APIs were made available that let developers utilize face detection, barcode recognition, and facilitated Nearby Messages.

Google Offers Cheaper Version of Cloud Services to Run Low Priority Jobs

Some departments in your company do not need cloud computing resources to carry high-performance tasks, right? Because Google has just formatted a service plan for such demands. Google launched Preemptible Virtual Machine, a new cloud service that allows to use computing resources at low costs. The offer is suitable for workloads with low priority and can, therefore, be interrupted.

The search giant introduced a new cloud platform that cost 70% less than the same default setting in Compute Engine. The Preemptible Virtual Machine can do well cheap, about $ 0.01 per instance/hour. The most affordable VM charges per hour can range anywhere between $ 0.03 per hour, up to $ 0.11 per hour or more. The problem is that the VMs may stop working when you need it or face peak periods.

The company argues, however, that the offer (in beta) serves very well the various computational tasks. The company cites, for example, some critical workflows that can be distributed among multiple virtual machines. However, it would be a bad idea to adopt the approach to process analysis, modeling, and simulations that require high computing power and instant answers.

To provide the service, Google will use the free capacity in its data center. At times when there is a peak in demand and Google needs more resources, virtual machines involved in Preemptible Compute Engine VMs are recalled and interrupts the current processing. Users receive a notice period of 30 seconds, which should be enough to save your work. Google said No Preemptible VM can run for more than 24 hours straight.

According to the Google post, “all machine types are charged a minimum of 10 minutes. For example, if you run your instance for 2 minutes, you will be billed for 10 minutes of usage. After 10 minutes, instances are charged in 1 minute increments, rounded up to the nearest minute. For example, an instance that lives for 11.25 minutes will be charged for 12 minutes of usage.”

According to Google, there are many that utilize cloud scalability and pricing model to calculate relatively intensive, but short-term assignments. It includes the coding of video, reproduction of visual effects and calculations based on large amounts of information, such as in data analysis, simulation, and genomics.

The solution is quite similar to that of Spot Instances offered by Amazon Web Services (AWS). The model of AWS differs in price. Google has a fixed cost while the competitor price varies according to demand.

The market leader AWS routinely cuts their cloud pricing. The company is facing tough competition with Google and Microsoft to maintain its lead in cloud computing and tries to woo more developers to come to its solutions with lower prices, more hardware offerings and more advanced technologies. Microsoft, on the other hand, progressed enough to be a serious threat to Amazon’s dominance in the market.
