# Android Demo quick start
### 1. Install the latest version of Android Studio
It can be downloaded from https://developer.android.com/studio . This Demo is written by Android Studio version 4.0.
### 2. Create a new project
The NDK version 20b is used in the demo test, and the compilation can be successfully supported for version 20 and above.
If you are a beginner, you can install and test the NDK compilation environment in the following ways.
File -> New ->New Project to create "Native C++" project
1. Start a new Android Studio project
Select Native C++ in the project template, select Paddle OCR/deploy/android_demo path

exit the project after compiling, and enter again.
### 3. Send to mobile
Complete the compilation, click Run, and check the effect on the mobile phone.
### 4. How to customize the demo picture
1. Image storage path: android_demo/app/src/main/assets/images
