Android OCR Demo

Simple app shows you how to do OCR on Android platform

1. This project use tess-two project to do OCR, using tess-two project make it simple to develop OCR Android project, you don't need to do any native coding and compiling work, just reference this project and use it as java package.

2. Currently this Android OCR Demo support 2 languages: English and Chinese, effect for English is better than Chinese. If you want to do other language OCR, please goto tesseract-ocr project and download the trained model for your specific language, or you could train your OCR model yourself, but model training is non-trivial task.

3. Alought OCR is developed by c, by using tess-two project, you don't need to care about Android hardware platform (armeabi, armeabi-v7a, mips, x86), usually for NDK development, hardware platform is really trivial thing you need to care about.

Android NDK Demo

Simple app shows you how to develop native c/c++ by NDK on Android platform

1. This project is really a simple demo project that shows you how to configure native code development and how to develop native code in c/c++, how to compile native code by NDK, how to call native code in Android project by JNI.

2. The main purpose of this project is give you an example that showing how to configure NDK development environment. Please goto NDK Demo to see the detailed setup instructions.

3. In order to develop your customized Android app by native code, you need to understand basic mechanism of JNI.
