PERFETTO-TRACE File – What is .perfetto-trace file and how to open it?
PERFETTO-TRACE File Extension
Android System Trace – file format by Google
PERFETTO-TRACE is a file extension for Android System Trace files. These files contain data about the performance of an Android system, including information about processes, threads, and system calls. Developers can use this data to diagnose performance issues and improve the performance of their apps.
What is a PERFETTO-TRACE File?
A PERFETTO-TRACE file is a binary file that contains a trace of system activity. It is used to profile the performance of Android applications and system components. The trace contains information about CPU usage, memory usage, disk I/O, and network activity. It can be used to identify performance bottlenecks and optimize the system.
How to Create a PERFETTO-TRACE File
To create a PERFETTO-TRACE file, you can use the “perfetto” command-line tool. The following command will create a trace file named “trace.perfetto-trace”:
perfetto record -o trace.perfetto-trace
You can also use the Android Studio Profiler to create a PERFETTO-TRACE file. To do this, open the Profiler window and click on the “Record” button. The Profiler will create a PERFETTO-TRACE file in the “traces” directory of your project.
How to Analyze a PERFETTO-TRACE File
You can analyze a PERFETTO-TRACE file using the “perfetto-analyzer” tool. The following command will open the trace file in the Perfetto UI:
perfetto-analyzer trace.perfetto-trace
The Perfetto UI provides a variety of tools for analyzing the trace data. You can use these tools to identify performance bottlenecks and optimize the system.
Opening PERFETTO-TRACE Files on Android Devices
PERFETTO-TRACE files are generated by the performance profiling tool Perfetto, which is built into Android devices running Android 8.0 (Oreo) and later. These files contain a detailed record of system activity, including CPU usage, memory usage, and network traffic. To open a PERFETTO-TRACE file on an Android device, you can use the Perfetto Viewer app, which is available for free in the Google Play Store. Once the app is installed, you can open a PERFETTO-TRACE file by navigating to the file in the file manager and tapping on it. The Perfetto Viewer will then load the file and display a graphical representation of the system activity data.
Opening PERFETTO-TRACE Files on Other Platforms
In addition to being able to open PERFETTO-TRACE files on Android devices, you can also open them on other platforms, including Windows, macOS, and Linux. To do this, you will need to install the Perfetto Trace Viewer, which is available for download from the Perfetto GitHub repository. Once the Trace Viewer is installed, you can open a PERFETTO-TRACE file by dragging and dropping it onto the Trace Viewer window. The Trace Viewer will then load the file and display a graphical representation of the system activity data.
File Format
PERFETTO-TRACE files are binary files that store traces of system activity on Android devices. They are generated by the perfetto tracing tool, which is part of the Android SDK. PERFETTO-TRACE files contain a variety of data, including CPU usage, memory usage, and network activity. This data can be used to identify performance bottlenecks and other issues that can affect the performance of an Android device.
PERFETTO-TRACE files can be analyzed using the Android Studio profiling tools. To analyze a PERFETTO-TRACE file, open it in Android Studio and select the “Trace Viewer” tab. The Trace Viewer will display a timeline of the data in the file. You can zoom in and out of the timeline to view the data at different levels of detail. The Trace Viewer also provides a number of tools that can be used to analyze the data, such as a flame graph and a call tree.
