This is the first part of a blog post series about bytecode transformations on Android. In this part we’ll cover different approaches to bytecode manipulation in Java as well as how to make it work with Android and the Android Gradle plugin. In the next two parts we’ll dive into the actual bytecode, bytecode instructions and how we can modify the bytecode and inject our own instructions, using Room as an example.

Now every developer can customize the performance monitoring charts and data views on the Performance page to see what is most important to them and their team, helping prioritize relevant performance monitoring metrics so they can take action faster.

Over the last year we added Sentry’s error monitoring to our developer environment so that we could better understand the health of it. In this blog post I’m going to touch on how fragile local development environments can be, how we brought observability into what’s happening by introducing Sentry, and what outcomes it has driven for our engineering organization.
