How Do I profile a native android application with Streamline

FabianSchuetze

How can I profile a Native Application on the Android device?


Suppose I have an native application and can execute it on an Android device at `/data/local/tmp/my.bin` . How can I profile this application with Streamline?

Inspired by this thread: https://community.arm.com/support-forums/f/armds-forum/9615/profiling-android-native-code I have pushed `gatord` (located at `Arm_Performance_Studio_2024.0/streamline/bin/android/arm64/` to the android device and run the exectuable like so:

```

./gatord --output /data/local/tmp/ --app my.bin                          
``

However, I cannot see a trace file afterwards. How could I profile this application?

    Hi

    That is generally correct, you should give the name of the capture as part of output, so something like:

    ./gatord -o /data/local/tmp/capture.apc -A application args...

    ought to work.

    Refer to `--help` for a list of command line arguments used to configure the target (see for example `--print counters`, and `-C` for configuration).

    You can also use the Streamline UI to make a live capture from the target in this configuration (which will allow you to apply GPU templates if you are interested in such things)... run gatord like:

    ./gatord -A application args...


    and then use the "TCP/IP" option, rather than the "Android" option in the "Start" tab. If your device is connected by adb/usb, and the adb command is in the PATH (or is configured in the Streamline UI preferences) then you should see the device appear in the list of available devices.
