We get a description, links to the documentation and even video links for relevant talks on that subject. The alert states that there was a long View#draw() call.

Let’s look at a trace I took, and select one of the alerts on the top: The interesting parts are the Alerts and the Frames, showing you insights the tool has generated based on the data it collected. On the video, I explained the different sections.

You can generate a trace file using the Android Device Monitor tool, or using command line. In one of the latest SDK tools updates, this tool was improved with generated insights from the data, helping us to find problems. This tool reminds us that the phone we hold in our hands, is actually is a powerful computer that can do many things at the same time. Systrace shows us an overview of what’s currently running on the phone. That’s because developers weren’t sure what to do with the information it provides. Systrace is one of the greatest tools that you probably don’t use. In many cases, that other thing can be your time spent finding and fixing it, but it can also be the quality of your bitmaps or the amount of data you should store in a specific data structure. You optimize one thing - it comes on the expense of another. Trade-offs - Performance optimization is all about trade-offs. Newer and stronger devices might not get too excited about performance issues you may have, but not all your users use the latest and greatest. Use slow devices - If you really want to expose all the weak spots, slower devices will help you more. Use the tools we’ll go over soon, and measure how your app performs a few times before and after you make your change. After looking at the same animation for a few times, you’ll start imagining it’s running faster. Now, Let’s go over some of the important things I was talking about, hopefully I can give a deeper explanation for everything, starting with the basic rules I follow when I work on optimizations: My RulesĮverytime I approach a performance problem, or looking for performance problems, I follow these rules:Īlways Measure - Optimizing with your eyes is never a good idea.
