Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.priyankvex:Easy-Ocr-Scanner-Android:'
	}
	dependencies {
		implementation("com.github.priyankvex:Easy-Ocr-Scanner-Android:")
	}
	<dependency>
	    <groupId>com.github.priyankvex</groupId>
	    <artifactId>Easy-Ocr-Scanner-Android</artifactId>
	    <version></version>
	</dependency>

                            
    libraryDependencies += "com.github.priyankvex" % "Easy-Ocr-Scanner-Android" % ""
        
        

                            
    :dependencies [[com.github.priyankvex/Easy-Ocr-Scanner-Android ""]]

# Easy-Ocr-Scanner-Android Easiest and simplest OCR scanner library for Android built using Tesseract and Leptonica.

<h2>About</h2>

Easy OCR Library is made by having only one goal in mind: Making OCR as easy as possible. (Don't you just love when things actually mean what they show).

Easy OCR uses a fork of tesseract, <a href="https://github.com/rmtheis/tess-two">Tess Two</a>. But deals with all the pain of setting up and building the library using NDK.

<h2>Usage</h2>

Using EasyOcrLibrary is as simple as it can get.

<b>Step 0</b>

Copy your trained data file into the assets/tessdata folder. You can download the required .traineddata file from <a href="https://code.google.com/p/tesseract-ocr/downloads/list">here</a>.

<b>Step 1</b>

NOTE : "eng" is the name of the traineddata file as here we are using eng.traineddata .

 // initialize EasyOcrScanner instance.
mEasyOcrScanner = new EasyOcrScanner(MainActivity.this, "EasyOcrScanner",
        Config.REQUEST_CODE_CAPTURE_IMAGE, "eng");

<b>Step 2</b>

Implement java EasyOcrScannerListener.

implements EasyOcrScannerListener

Then define the callbacks.

<b>Step 3</b>

Start the scan!

mEasyOcrScanner.takePicture();

<b>Step 4</b>

Call java onImageTaken() in java onActivityResult()

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        // Call onImageTaken() in onActivityResult.
        if (resultCode == RESULT_OK && requestCode == Config.REQUEST_CODE_CAPTURE_IMAGE){
            mEasyOcrScanner.onImageTaken();
        }
    }

<b>And you are done!</b>

Get the scaned text in the callback java onOcrScanFinished().
