The tool is particularly useful for Tor development +because it is able to profile native applications on the platform +whereas a lot of the normal tooling for the Android platform is only +able to collect information from Java-based applications. + +## Prerequisites + +Before using `simpleperf` there is a couple of steps that must be +followed. You should make sure you have both a recent installation of +the Android Software Development Kit (SDK) and Native Development Kit +(NDK) installed. These can be found on the Android Developers website. + +1. Follow the build instructions from the `BUILD` file in the Orbot + repository and build an Orbot APK (Android Package) file with + debugging enabled. Make sure that when you build the native content of + the Orbot application that you run the `make -C external` command with + an additional `DEBUG=1` as paramter to ensure that the Orbot build + process does not strip the debug symbols from the Tor binary. + +2. (Optional) Uninstall and clean-up your old Orbot installation that + is most likely downloaded from Google's Play Store or via fdroid: + + $ adb shell pm clear org.torproject.android + $ adb uninstall org.torproject.android + +3. Install the Android Package you generated in step 1: + + $ adb install /path/to/your/app-fullperm-debug.apk + +4. Check on your device that the newly installed Orbot actually works + and behaves in the way you expect it to. + +## Profiling using `simpleperf` + +The `simpleperf` tool can be found in the `simpleperf/` directory in +the directory where you installed the Android NDK to. In this +directory there is a set of Python files that will help you deploy the +tool to a device and collect the measurement data such that you can +analyze the results on your computer rather than on your phone. + +1. Change directory to the location of the `simpleperf` directory. +2. Open the `app_profiler.config` file and change + `app_package_name` to `org.torproject.android`, `apk_file_path` to + the path of your Orbot Android Package (APK file). +3. Optionally change the duration parameter in the `record_options` + variable in `app_profiler.config` to the duration which you would like + to collect samples in. The value is specified in seconds. +4. Run the app profiler using `python app_profiler.py`. This helper + script will push the `simpleperf` tool to your device, start the + profiler, and once it has completed copy the generated `perf.data` + file over to your computer with the results. + +### Analyzing the results + +You can inspect your resulting `perf.data` file via a simple GUI +program `python report.py` or via the command-line tool `simpleperf +report`. I've found the GUI tool to be easier to navigate around with +than the command-line tool. + +The `-g` option can be passed to the command line `simpleperf report` +tool allows you to see the call graph of functions and how much time +was spend on the call. + +## Tips & Tricks + +- When you have installed Orbot the first time, you will notice that + if you get a shell on the Android device that there is no Tor binary + available. This is because Orbot unpacks the Tor binary first time it + is executed and places it under the `app_bin/` directory on the + device. + + To access binaries, `torrc` files, and other useful information on + the device do the following: + + $ adb shell + (device):/ $ run-as org.torproject.android + (device):/data/data/org.torproject.android $ ls + app_bin app_data cache databases files lib shared_prefs + + Descriptors, control authentication cookie, state, and other files can be + found in the `app_data` directory. The `torrc` can be found in the `app_bin/` + directory. + +- You can enable logging in Tor via the syslog (or android) log + mechanism with: + + $ adb shell + (device):/ $ run-as org.torproject.android + (device):/data/data/org.torproject.android $ echo -e "\nLog info syslog" >> app_bin/torrc + + Start Tor the normal way via Orbot and collect the logs from your computer using + + $ adb logcat +
