Unlock the Power of Android Profiler: A Comprehensive Guide
What is Android Profiler?
Android Profiler is a built-in tool in Android Studio that provides real-time data about your app’s performance, including CPU, memory, network, and energy usage. This powerful tool is available on all Android Studio versions above 3.0.
Setting Up Android Profiler
To get started with Android Profiler, navigate to View, Tool Windows, and select Profiler. This will open the Profiler window at the bottom of the screen. Next, run your app from Android Studio on your phone or emulator. The Android Profiler will automatically pick up the process and add a new session.
Profiling Network Usage
With Android Profiler, you can profile the network usage of your app, ensuring that it doesn’t perform any unwanted network activity. To do this, open the Network Profiler, which will show you all the network requests and responses in real-time. You can hover over the graph to find out the size of data sent and received at a particular instant, helping you evaluate if correct network requests and responses are being performed at the correct time.
Profiling Energy Usage
Use the Energy Profiler to determine if your app drains more battery than it should. This profiler estimates power consumption by the resources your app consumes, helping you identify areas for improvement. You can run Energy Profiler on an emulator, too.
Profiling Memory Usage
The Memory Profiler helps you debug crashes, applications not responding (ANRs), and freezes due to memory leaks in your app. This profiler splits memory into various components, such as Java, native, graphics, etc., and shows the number of objects allocated. You can capture a heap dump to record all the objects allocated by Android OS and your application.
Profiling Events
Monitor events like touch, activity transitions, and device rotations using the Events Profiler. Touches are registered as red dots right above the name of the displayed activity. You can hover over the blue line to get more details about the displayed activity and fragment.
Profiling CPU Activity
Analyze your app’s CPU usage and thread activity in real-time using the CPU Profiler. You can see the list of all the threads in your application, and thread states are indicated by three colors: green (running), yellow (active but waiting), and gray (inactive). To get a more detailed view, press the record button and edit the sampling rate as needed.
The Power of Android Profiler
Android Profiler makes it easy to find bugs or troubleshoot your Android application. Without requiring any third-party library, Android Studio allows you to profile your application’s CPU, network, energy, and memory usage. With this powerful tool, you can build an app that is free from slow performance, high battery consumption, and memory leakages.
