Prerequisites

Android Studio

1. Download and install Adnroid Studio from https://developer.android.com/studio
2. Create a new project. Keep default settings.
3. Probably you'll face a error similar to the following:

Click onto highlighted link to resolve it. Then you may see the next one error:

Resolve it in the same way.

1. Plug in USB cable connected to device. Make sure that Developers Mode on the device is enabled. You may find an appropriate instructions for your version of OS.

2. Authorize an Android device.

• Ubuntu

  1. Install Android Debug Bridge

  $ sudo apt-get install adb
  

  1. Check device id

  $ lsusb
  Bus 003 Device 008: ID 1bbb:9018 T & A Mobile Phones
  

  1. Add the following line to /etc/udev/rules.d/51-android.rules (create it if there is no file). The first 4 symbols are vendor's id and the last one are product's id:

  SUBSYSTEM="usb", ATTRS{idVendor}=="1bbb", ATTRS{idProduct}=="9018", MODE=="0666"
  

  Note that sudo directive may be required. Apply sudo chmod a+rw /etc/udev/rules.d/51-android.rules after all above.

  1. Restart adb service. Probably, connection should be permitted from the device side (notification will appear). Check that device is detected by adb devices.

  $ sudo adb kill-server && sudo adb start-server && sudo adb devices
  List of devices attached
  PEJB25BF4MXAHN4 device
  

  1. In case of undetected device problem at Android Studio or permissions problems just restart adb again and make sure that device is detected.

• Windows

  1. No specific settings are required (tested on Windows 10).

1. Launch a project on device by Run->Run 'app'. Select detected device.

Python

2. NumPy

• sudo apt-get install python-pip && sudo pip install numpy for Ubuntu

OpenCV

1. Download OpenCV source code from https://github.com/opencv/opencv or using git:

git clone https://github.com/opencv/opencv --depth 1

1. Create a folder for OpenCV's build.

cd /path/to/opencv
mkdir build && cd build

1. Build OpenCV.

• Ubuntu

cmake -DCMAKE_BUILD_TYPE=Release -DBUILD_LIST=dnn,python2,videoio,highgui /path/to/opencv && make -j4

• Windows

  "C:\Program Files\CMake\bin\cmake.exe" ^
      -DCMAKE_BUILD_TYPE=Release ^
      -DBUILD_LIST=dnn,python2,videoio,highgui ^
      -G "Visual Studio 14 Win64" /path/to/opencv
  
  "C:\Program Files\CMake\bin\cmake.exe" --build . --config Release -- /m:4

Test Python and OpenCV

import cv2 as cv

img = cv.imread('/path/to/example.png')
cv.imshow('Hello!', img)
cv.waitKey()
