BUILDING.md

Building

This project may be built manually as an alternative to including the pre-built AAR as an external dependency in your app project. To start the build, import this project into Android studio. The project can be compiled as a whole or separately by modules. You can choose which module to modify and compile according to your needs.

Building ocr_zs module

This module needs to rely on the tess-two module, make sure you import dependencies before compiling, In Android Studio, use

Build -> Rebuild Project

or use the following commands:

./gradlew assemble

to build or rebuild the project.

Building tess-two module

The Gradle build uses the gradle-stable plugin and the Android NDK to build the Tesseract and Leptonica native C/C++ code through a call to ndk-build in build.gradle. In Android Studio, use

Build -> Rebuild Project

or use the following commands:

./gradlew assemble

to build or rebuild the project.

Note: When building from Android Studio, you may need to set the path to your NDK installation.

Edit your local.properties file to include the path to your NDK directory:

ndk.dir=/path/to/your/android-ndk

Importing

After building, the code that is generated may be imported into your app project in Android Studio as a module using

File -> New -> Import Module -> module_name folder

and then adding the dependency to your app/lib module build.gradle:

    dependencies {
        implementation project(':module_name')
    }

Removing

If you want to remove your app's dependency on this module, reverse the import process by removing the module using the Project Structure dialog(File->Project Structure), manually deleting the module subfolder from your app project folder, and removing the module reference from your app module build.gradle.
