When we run Systrace while using our app, -it will collect data from Android then format it into an html file we can view in a web browser. -When we open the Systrace results, we’re hoping it will be able to help us resolve some of the -underlying issues associated with our SDK. - -## Run systrace locally - -Execute following command in your terminal will run Systrace for 10 seconds: - -``` -python $ANDROID_HOME/platform-tools/systrace/systrace.py --time=10 -o ~/trace.html gfx view res -``` - -This command will output a file called `trace.html`. -More information how to interpret the values can be found [here](http://developer.android.com/tools/help/systrace.html). - -More information about this topic can be found [here](https://codelabs.developers.google.com/codelabs/android-perf-testing/index.html?index=..%2F..%2Fbabbq-2015&viewga=UA-68632703-1#0) - -## Automating Systrace with Espresso - -The following annotation is being used to isolate the tests and classes that should be included in the performance tests. - -```java -@PerfTest -``` - -You can optionally define extra rules to gather more data during a performance test: - -```java -@Rule -public EnableTestTracing mEnableTestTracing = new EnableTestTracing(); - -@Rule -public EnablePostTestDumpsys mEnablePostTestDumpsys = new EnablePostTestDumpsys(); - -@Rule -public EnableLogcatDump mEnableLogcatDump = new EnableLogcatDump(); - -@Rule -public EnableNetStatsDump mEnableNetStatsDump = new EnableNetStatsDump(); -``` - -## Automating Systrace with MonkeyRunner - -An example of such a script can be found [here](https://github.com/googlecodelabs/android-perf-testing/blob/master/run_perf_tests.py). -The script is following this structure: - -- Check environment variables -- Define functions -- Clear local data from previous runs -- Find an Android device -- Enable and clear graphics info dumpsys -- Start a systrace thread & test suite thread in parallel -- Wait for both threads to complete -- Download files from device -- Run analysis on downloaded files - -## Note -Testing on a device with minimum SDK 6.0 is preferred. -The tools above work on older versions of Android, but less data will be collected.
