Enhancing App Security on Google Play

Posted by Eric Davis, Android Security Team

We’re constantly investing in new tools and services to help developers build secure Android applications. This includes the application sandbox and Security APIs in the platform, Security APIs in Google Play Services, and even open source testing tools. Last year, Google Play also helped developers enhance the security of their applications by looking directly at the code they’ve written and offering suggestions for improvements.

The Google Play App Security Improvement Program is the first of its kind. It has two core components: We provide developers with security tips to help them build more secure apps, and we help developers identify potential security enhancements when uploaded to Google Play. This week, to help educate developers, Kristian Monsen, one of our engineers, gave a presentation about security best practices at the Samsung Developer Conference. And in 2015, we worked with developers to improve the security of over 100,000 apps through the program.

How it works

Before any app is accepted into Google Play, it is scanned for safety and security, including potential security issues. We also continuously re-scan the over one million apps in Google Play for additional threats.

If your app is flagged for a potential security issue, you will be notified immediately to help you quickly address the issue and help keep your users safe. We’ll deliver alerts to you using both email and the Google Play Developer Console, with links to a support page with details about how to improve the app.

Typically, these notifications will include a timeline for delivering the improvement to users as quickly as possible. Applications may be required to make security improvements before any other app updates can be be published.

You can confirm that you’ve fully addressed the issue by uploading the new version of your app to the Google Play Developer Console. Be sure to increment the version number of the fixed app. After a few hours, check the Developer Console for the security alert; if it’s no longer there, you’re all set!

The success of this program rests on our partnership with you—the developers of apps on Google Play—and the security community. We’re all responsible for providing safe, secure apps to our users.
