Use ADB Shell to Benchmark FeatherCNN on Android Devices.

This is an example to show how to test FeatherCNN on Android devices with a Ubuntu 16.04 desktop using adb tool. In the following, we illustrate necessary steps to show how it works.

Prerequisites

  • Install g++/gcc cross compiler for X86 platform and adb tools.
  sudo apt-get install gcc-aarch64-linux-gnu
  sudo apt-get install g++-aarch64-linux-gnu
  sudo apt-get install android-tools-adb

  cd NDK_PATH
  unzip android-ndk-r17b-linux-x86_64.zip 
  export NDK_ROOT=$NDK_PATH/android-ndk-r17

Build FeatherCNN for Benchmarking

  • Build FeatherCNN
    ./build_script/build_android.sh
    ./build_script/push_android.sh

A program named as test will be generated, and you can find 3 executable files with:

    find . -name "test"

and then it outputs:

./test/libs/arm64-v8a/test
./test/obj/local/arm64-v8a/objs/test
./test/obj/local/arm64-v8a/test
  • copy any one of the generated program and its related data to android devices
  adb push ./test/libs/arm64-v8a/test /data/local/tmp
  adb push ./data/input_3x224x224.txt /data/local/tmp
  adb push ./data/mobilenet.feathermodel /data/local/tmp
  • benchmarking
  adb shell ./data/local/tmp/test ./data/local/tmp/mobilenet.feathermodel ./data/local/tmp/input_3x224x224.txt 10 1
