Android OCR 한글 및 영문 인식 Tesseract 샘플 프로젝트 테스트

http://cofs.tistory.com/175 우선 이거 따라해 봐야겠다.

1. 새 프로젝트 생성

2. https://github.com/GautamGupta/Simple-Android-OCR 에서 샘플프로젝트 다운로드

2-1. import를 시도해 본다.

File > New > Import Project..

> 다운로드 후 압축을 푼 경로 선택 > OK

> Next

> Next 

> 안되네..

압축을 푼 Simple-Android-OCR 폴더 안에 

https://github.com/rmtheis/tess-two 에서 tess-two를 다운 받아서 넣는다.

Simple-Android-OCR / project.properties 에서 

android.library.reference.1=../tess-two 를

android.library.reference.1=C:/Users/경로입력/Desktop/Simple-Android-OCR-master/Simple-Android-OCR-master/tess-two 로 변경 후 저장.

안드로이드 스튜디어에서 프로젝트 import 

되긴 함.

2. https://github.com/tesseract-ocr/tessdata 여기에서 tessdata 다운로드 ( 언어팩 )

http://cofs.tistory.com/175 여기 2번에 보면 assets/tessdata폴더에 넣으면 된다고 한다.

음.. 폴더가 없다면 app/src/main아래에 assets폴더를 생성하라고 한다. 

3. tess-two 모듈 다운로드 및 Import 하고 jar설정

File > New > Import Module.. 이 부분은 건너뜀

FIle > Project Structure > Modules > 프로젝트 선택 > 가장 끝에 있는 Dependencies 탭 선택

> + 기호 누름 > Module dependency > tesstwo선택 > OK > OK

4. 설정 파일(tess-two의 build.gradle) 수정 

Simple-Android-OCR-master / simpleAndroidOCR / build.gradle와

Simple-Android-OCR-master / tesstwo / bulid.gradle의 상단 부분은 같아야 한다고 한다. 아마도..

->  

Simple-Android-OCR-master / tesstwo / bulid.gradle 하단에 블로그에 나와있는 소스를 붙여넣는다.

+ 

compileSdkVersion 24
buildToolsVersion "24.0.0"

defaultConfig {
    applicationId "com.datumdroid.android.ocr.simple"
    minSdkVersion 23
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
}

이렇게 내용 수정함.

5. 실행을 해야 하는데..

Error:(17, 0) Gradle DSL method not found: 'compile()'
Possible causes:The project 'Simple-Android-OCR-master' may be using a version of Gradle that does not contain the method.
Open Gradle wrapper file 
The build file may be missing a Gradle plugin.

여기가 문제라는 건가,,,

simpleAndroidOCR/build.gradle
tesstwo/build.gradle
/build.gradle
여기에서 
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:24.0.0'
    compile 'com.android.support:design:24.0.0'
}
이렇게 바꿔봄.. 에러가 안사라짐..


Error:(35, 0) Could not find property 'Os' on task ':tesstwo:ndkBuild'.
Open File



Error:(7, 0) Gradle DSL method not found: 'compile()'
Possible causes:The project 'Simple-Android-OCR-master' may be using a version of the Android Gradle plug-in that does not contain the method (e.g. 'testCompile' was added in 1.1.0).
Fix plugin version and sync project

The error is saying that your project depends on google_Play_Service_Lib and android studio is not able to find that dependency, but what android studio did is giving you the path where you can paste that library and then you will able to import that project. first download google_service_lib from https://github.com/aporter/coursera-android/tree/master/Examples/google-play-services_lib or https://github.com/MobileChromeApps/google-play-services and now paste that in E:\android\CFPEvents\cfp-android-user now again import..

Using 'minifyEnabled' instead of 'runProguard' works properly. Previous code : buildTypes { release { runProguard false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } Current code : buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } Hope this helps . shareimprove this answer edited Apr 11 at 13:13 answered Dec 3 '14 at 7:54 Amitabha Biswas 2,9191417

If you are migrating to 1.0.0 you need to change the following properties. In the Project's build.gradle file you need to replace minifyEnabled. Hence your new build type should be buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } Also make sure that gradle version is 1.0.0 like classpath 'com.android.tools.build:gradle:1.0.0' in the build.gradle file. This should solve the problem.

By changing runProguard to minifyEnabled, part of the issue gets fixed. But the fix can cause "Library Projects cannot set application Id" (you can find the fix for this hereAndroid Studio 1.0 and error "Library projects cannot set applicationId"). By removing application Id in the build.gradle file, you should be good to go. shareimprove this answer answered Feb 5 '15 at 15:59 Sandeep Kumar 25925

Try to trace the answer here and then give the link to it. – codebot Feb 9 '15 at 6:30 Somebody should have told that already. Great! After doing minifyEnabled, need to do this as well in buld.gradle of all the external library projects as well. – sud007 Mar 17 '15 at 8:28 add a comment

runProguard has been renamed to minifyEnabled in version 0.14.0 (2014/10/31) or more in Gradle. To fix this, you need to change runProguard to minifyEnabled in the build.gradle file of your project.
