Regardless, DDMS can come in handy if you’re working on an earlier version of Android Studio, or if you are looking for a manual approach to debugging Android applications. The recommend substitute for DDMS is the new Android Profiler, which we’ll discuss later. DDMS runs apps, streaming the output of the apps’ debuggers directly to your command line.ĭDMS is a very advanced tool, however, it is important to note that this tool is deprecated in Android Studio v3.0. DDMS acts as a bridge between your apps and your command line, connecting directly to the virtual machines in your phone. Known as Dalvik Debug Monitor Server, the profiling tool can be launched directly from the command line. The Android SDK contains an independent Java application that you can use to monitor your Android app’s performance in real-time. If you don’t use Android Studio, or you’re not satisfied with the on-device profiling features that ship with Android, there is another alternative for you. We’ll dive into more detail on Android Studio in a later section. Each metric has a separate profiling section and provides a range of tweaks and customizations. With Android Studio, you can profile almost anything ranging from memory to battery. Android StudioĪndroid Studio is the de facto IDE for Android application development, so it comes packed with a ton of profiling abilities. You can learn more about it on the official Android Developers website. The graph also contains information like the time taken by each component of the rendering lifecycle, represented using bars of different colors. The height of the bars indicates the time it took for the device to render that frame on the screen. You’ll notice bars like the ones below on the bottom of your screen: Image source: Android DevelopersĮach vertical bar in this graph represents a frame of your app’s UI. In the dialog that pops up, choose On Screen As Bars option.Under the Monitoring section, choose the Profile GPU Rendering option.You can use the developer tools provided on every Android phone to profile GPU performance on the fly. There are multiple approaches that you can take to profile an Android application, but in this section, we’ll cover three. Apps that consume a high amount of battery are usually uninstalled by users quickly. Lastly, since all mobile devices run on some form of battery, you need to optimize your app to consume as little battery as possible. Improper network management can add unnecessary delays to content loading times, causing a bad experience for your users. Most Android applications rely on a remote server to provide content and information. Improper management can lead to laggy UIs, app slowdowns, and in the worst case, complete freezes. Processing is what controls the experience of your users when navigating through your app. As one of the most crucial, yet limited resources on mobile devices, improper memory management can lead to App Not Responding errors (ANRs) and application crashes. When profiling your Android apps, there are multiple areas that you can focus on, for one, memory. Without Android profiling, performance optimization would be nearly impossible. Therefore, it is essential that you optimize your app’s resource consumption to provide the best possible experience for your users. Profiling is a software development practice that helps identify performance and resource management bottlenecks in an application.Īndroid apps are meant to run on Android devices, which usually have limited hardware resources. Tip #4: Utilize contexts well to reduce unnecessary memory leaks.Tip #3: Re-use UI elements as much as possible. Tip #2: Avoid nesting layouts deeper than two to three levels.Tip #1: Relieve the UI thread by delegating to background threads.Android resource management best practices.On-device profiling via developer tools.What should Android profiling focus on?.We’ll cover what to look out for when profiling Android apps, how to get started with popular tools, and how to reduce resource overuse. In this guide, we’ll cover the fundamentals of profiling Android applications. While there are a lot of tools and platforms available to benchmark hosted apps, mobile apps often slip under the radar. Without proper performance monitoring, your application could be using up valuable resources unnecessarily, potentially causing revenue losses that could easily have been avoided.
