In Might 2022, Google introduced the Google Play SDK Index. That is a part of their efforts to supply extra data and transparency to builders. In line with Google, greater than 80% of the code that may be present in a median utility comes from SDKs. If you consider it for a second, you’ll notice that numerous code in an app just isn’t developed by the app developer himself. That is fairly wonderful, actually.
Builders are particularly involved about third-party libraries, as they’ll pose numerous issues:
- safety flaws
- Inflation app dimension
- Trigger crashes/errors
- Complicate dependencies
That is why it’s important for builders to know that they’ll belief third-party libraries. However how can builders know that third-party library code is nice for them to make use of? Some builders depend on what number of stars an SDK has on GitHub or assume that if different folks use it, then it ought to be tremendous. Nonetheless, these choices usually are not a whole take a look at.
Google Play’s SDK Index may assist builders really feel extra snug.
However what does this SDK Index present to builders? And the way does it make it easier to make extra knowledgeable choices about selecting a third-party library to make use of inside your purposes?
SDKs for everybody
The unique intention behind selecting a 3rd celebration library is to not code one thing that another person has already performed. And hopefully performed with ease. However every SDK might have a distinct function that it serves. Some might make it easier to show adverts, others gather analytics knowledge, and so forth. That is why Google’s SDK index is split into 9 classes:
- Promoting and monetization
- Analytics
- Knowledge administration
- Location
- Advertising and engagement
- Funds
- Social
- Consumer authentication
- Consumer assist
Once you click on on a selected SDK, you will note a display that presents numerous details about it. The very first thing that can catch your consideration is whether or not or not that SDK is a part of the Google Play Console SDK (registration badge).

The screenshot above exhibits that the Regulate SDK is a part of the Google Play SDK Console, and this helps you perceive that the folks behind this SDK have made a dedication that their SDK won’t trigger your app to violate Google Performs insurance policies.

How essential is that this issue for you as a developer to contemplate? That is primarily so that you can say.
Unpacking an SDK
Let’s check out all the info uncovered about every SDK within the Google Play SDK Index. In line with Google makes use of “Google Play app utilization knowledge with SDK code detection” to present you all kinds of concepts.
If we take the Regulate SDK instance above, we will see that the SDK particulars web page is separated into a number of sections:
- SDK Particulars
- Android integration
- SDK Adoption by Amenities
- SDK Adoption by Model
- android permissions
- SDK retention per app
- SDK Variations
As an alternative of describing every part, let’s deal with those that imply probably the most to you, the app developer.
Within the Android integration you may see what API degree the SDK has been examined in opposition to and what’s the minimal API that the SDK requires.

Underneath the SDK Particulars there’s a hyperlink to the Information within the knowledge safety part, which is able to take you to the SDK proprietor’s web site. There you will note how they gather knowledge and what they use it for.

the Android permissions The part, as you will have guessed, exhibits what permissions the SDK requests.

After all, there’s an asterisk (⭐️) right here, as a result of if you happen to hover over the query mark subsequent to the title, you will uncover that:
Returns a listing of Android permissions that defend an API that makes use of at the very least a current model of the SDK. An SDK model is taken into account current if it was launched throughout the final yr. This consists of non-obligatory use by the SDK the place the SDK doesn’t at all times require this permission and may solely use it if the applying has made it accessible.
Word: Google Play can’t at all times detect all permissions utilized by an SDK.
be part of the pack
Chances are you’ll be questioning, how does an SDK get included within the index? Effectively, there’s a easy reply for that. You need to meet the next standards:
- Fall into one of many classes listed above
- Meet energetic person and app set up thresholds
- Distributed via a Maven repository
If you’re an SDK proprietor and meet the above guidelines and want to be listed within the Google Play SDK index, you may full the shape under.
For the lovers, you will have seen that at level n. In #2, Google maintains its ambiguity, because it has not publicly disclosed thresholds for energetic apps and person installs. You might have additionally seen that a number of the knowledge that Google presents is just for apps with over a thousand installs.
Whereas this initiative remains to be pretty new, I sit up for seeing the way it will develop within the close to future. Google goals to supply extra data and transparency, however because it stands, it is midway there. There may be far more to be desired and it’ll even be attention-grabbing to see if (and the way) Apple responds to this.
