# Android
Tesseract can be built for Android as a static command-line executable `tesseract`, or you can use [Java binding](https://github.com/rmtheis/tess-two) to work with **libtess** from your Android app.
Currently, the easiest build method can be found in a [tess-two fork](https://github.com/alexcohn/tess-two). This fork contains both tesseract and leptonica sources, so that it is enough to download the repository. To build the command-line executable, you don't need Android SDK or Android Studio, only install Android NDK (r.20 has been tested) and run the `ndk-build` command, e.g.:
```
ndk-build -C tess-two-git/tess-two tesseract APP_ABI=arm64-v8a
```
