So, for nested calls, such as those in the following snippet, make sure that you properly match each call to beginSection() with a call to endSection().Īdditionally, you cannot call beginSection() on one thread and end it from another thread you must call both methods on the same thread. I just ran adb shell id on my Pixel 4 and it only returns one line. It expects one line but on your device it outputs two, the first being 'uid2000 (shell).' and the second an empty string. Note: When you call beginSection() multiple times, calling endSection() ends only the most recently called beginSection() method. S-DA92 1 1 Looking at the code in deviceutils.py, I think it runs the id shell command and uses the output to determine if the device 'has root'. In Android 4.3 (API level 18) and higher, you can use the Trace class in your code to define customevents that then appear in Systrace reports, as shown in the following codesnippet. This guide describes how to define custom events in both managed code and nativecode. Note: This approach is different from using the Debug class, which helps you inspect detailedapp CPU usage by generating. It includes tools that interface with the Android platform, such as adb, fastboot, and systrace. html sched freq idle am wm gfx view binder_driver hal \ The Android SDK Platform-Tools is a component for the Android SDK.
If you capture a new system trace of the "debug"version of your app and include the -a option, as shown in the followingsnippet, these custom events appear in a Systrace report:
The Android platform provides a tracing API which you can use to label aparticular section of code. Systrace shows you information about processes onlyat the system level, so it's sometimes difficult to know which of your app orgame's methods were executing at a given time relative to system events.
