What is system tracing on my android?
System tracing on Android refers to a process of recording system-level events on the device. This process can be used for performance analysis and debugging purposes.
System tracing was introduced in Android 4.1 (Jelly Bean). To enable system tracing, you need to use the Android Debug Bridge (adb) tool. Once enabled, system tracing will record events such as CPU usage, memory allocation, and garbage collection. These events are then written to a trace file that can be analyzed later.
System tracing can be a useful tool for understanding the performance of your Android app. It can help you identify bottlenecks and optimize your code. However, system tracing can also be a battery drain, so it’s important to only enable it when you need it.

How does system tracing on my android work?
System tracing on your Android device is a process that allows you to see how your device is performing and where any bottlenecks are. This can be helpful in optimizing your device’s performance or in troubleshooting any issues you may be having.
System tracing works by taking a snapshot of your device’s current state and then recording all subsequent events that occur. These events can include anything from process start/stop to garbage collection to file I/O. Once the trace is complete, you can then analyze it to see where any potential issues are.
There are a few different ways to perform system tracing on Android. The most common way is to use the Android Debug Bridge (ADB). This tool is included with the Android SDK and allows you to connect to your device and run commands on it.
Alternatively, you can also use the Systrace tool from Google. This tool is a bit more advanced and requires you to have a rooted device. However, it provides more options for tracing and can be helpful in more difficult cases.
Once you have chosen a method for tracing, you will need to select which trace options to enable. There are many different trace options available, so it is important to only enable the ones that are relevant to your needs. Otherwise, the trace will be much larger and more difficult to analyze.
Once you have enabled the desired trace options, you can start the trace. This will typically take a few minutes to complete, depending on the trace options and the speed of your device. Once the trace is complete, you can then save it to a file and analyze it later.
System tracing can be a helpful tool in optimizing your Android device’s performance. By understanding where any bottlenecks are, you can make changes to improve your device’s speed and efficiency.
