11 Weeks of Android

We are continuing 11 Weeks of Android with new topics every week. Since the last Now in Android episode, we finished off Machine Learning, spent a week on Privacy & Security, and are now in the midst of Android 11 Compatibility. Here’s how to find out more about each of these topics:

Week 2: Machine Learning

So much [machine] learning!

Check out the blog posted at the end week for a summary of all of the content and information:

Also, check out the ML week video playlist.

Week 3: Privacy & Security

Week three brought content on platform changes aimed at protecting user privacy as well as information on what we’ve been doing to make the platform more secure. For privacy, there were articles and videos on some of the important behavior changes in Android 11, such as one-time permissions, background location, scoped storage, and auto-reset permissions. On the security front, the team posted content on what they’ve been up to in securing the platform, as well as features for developers, like biometric APIs, to make apps more secure.

First, check out the introduction blog:

Android 11 Meetups

Playing Those Bills

One of the major ways that apps make money is through in-app purchases, which are enabled through Play Billing’s tools, services, and APIs.

Caren Chang published Part 1 in a series of articles to help you get started. This first installment gives an introduction to Play Billing, including adding items to your Google Play Console and querying those items using Play Billing APIs.

ADB Podcast Episodes

There’s been another episode of Android Developers Backstage posted since the last Now in Android. Check it out at the links below, or in your favorite podcast client.

Many of the current episodes of ADB are being planned around #11WeeksofAndroid focuses (foci? points of focus? things upon which we focus? Hmmm: how about ‘topics’), and the latest episode on Privacy was no exception:

ADB 143: Shhhh! Private!
