UPDATE: so it does work on a real phone, but not on the emulator. At least it
works on my Nexus 1 running Android 2.3.3.

Hi,
In the code u have given,
boolean ok = api.init(dir, "eng");
can u please share,what does the "dir" refer to?
Thanks in Advance,

dir is a String containing the parent directory of the tessdata directory, in
this case dir = "/mnt/sdcard/".
Further update: it seems to have something to do with the version of Eclipse.
It didn't work on Helios V2, but on v3.6.2 with the same Android SDK it works!

Thanks for the reply Ian,
I have compiled the tesseract,leptonica and libjpeg in Ubuntu Linux as per the
instructions given in "read me" in tesseract-android-tools.I am also able to
initialize the tesseract engine.When I try to call "setImage" method passing
image in bytes format,it is accepting the image , but returning some different
junk characters every time(it is changing each time for same image) on calling
getUTF8Text.
I even tried calling "setImage" method passing Bitmap image, but it is
returning"Bitmap functions not available; library must be compiled under
android-8 NDK" Error.
libjnigraphics.so is present in my library.
We are using Eclipse ganymade 3.5.2 for this.Macro declaration for Leptonica
and ZLib has been included in "config_auto.h" which were missing.
Can you please share any solution as we are struck with it quite long.Thanks in
advance

I am certainly no expert on tesseract, so I can only tell you what I did to get
it to work:
- Compile tesseract and leptonica on a Debian machine (obviously Ubuntu should
work too.)
- Upgrade Eclipse, Helios, Eclipse SDK, version 3.6.2 works for me.
- Import the tesseract project and set is as a library. I set the build target
as Android 2.2.
- Create a test project, same build target.
- You are correct that it doesn't work with bitmaps, which is very unfortunate.
The only way I could get it to work was so save the image as a jpeg file, then
pass the jpeg to tesseract to scan. This is obviously not very efficient, but
it's the only thing I could get to work:
TessBaseAPI api = new TessBaseAPI();
boolean ok = api.init(tessParentDir+"/", "eng");
if ( !ok ) {
l.error("Failed to initialize api");
return;
}
File f = new File(testImg); // testImg = "/mnt/sdcard/test.jpg"
if (f == null || !f.canRead() || f.length() < 1) {
l.error(testImg + " is not readable");
} else {
l.info("Trying to read file", 4);
try {
Pix px = ReadFile.readFile(f);
api.setImage(px);
l.info("File read", 4);
String text = api.getUTF8Text();
l.info("Text is >>>" + text + "<<<", 1);
TextView tv = (TextView) findViewById(R.id.result);
tv.setText(text);
} catch (Exception e) {
l.error("Failed to read test image " + e.getMessage());
}
}
api.end();
I suggest you try this with test image I uploaded.
Good luck!

i tried ianjones method :
1/ downloaded the ndk & tesseract tools project with the README
2/ compiled it on debian
4/ create a project based on android 2.1 on Eclipse (win 7)
5/ copied the 3 .so (libjpeg/libtess/liblept in libs folder
6/ copied TessBaseAP.java in my package project
When i start the program i have this errors :
"No implementation found for native Lcom/test/TessBaseAPI";.nativeClassInit ()V

I understand this an issue tracker but since there doesn't seem to be a forum
I'll ask my question right here since its related,
I've got the project compiled and a sample app up. I placed the downloaded
english language data files i.e. eng.traineddata under /mnt/sdcard/tessdata.
I see this abrupt crash on api.init()

I figured out that the directory name has to be "tessdata" and the library will
append that to the path you provide. In this case /mnt/sdcard/ was enough.
It's working now and I can get some results. The results are not as good as I
expected but I am happy i've got something working on device and the OCR is
fast.

Yep so the steps to make it works :
create folder "/sdcard/tessdata/"
put your language ("lang.traineddata", not the .gz) files in the folder
in your code, api.init("/mnt/sdcard/", "lang");
Voila !
Thanks to anirudith ;)

Hi,
reading the image as pix and setimage(pix) is working fine in emulator but when
I tried in my device its showing
"Failed to read pix from file"
where we trying to read the jpg file from disk and converting it to pix.
I mentioned the path correctly and im having that jpg image in the sdcard.
Im using HTC incredible with android v2.2. how to solve it?

Since I started this, I will provide a summary of what worked for me. I’m not
suggesting that this is how it must be done - it’s just how I got it work.
Create a test image file (you can use the one I uploaded above) and put it
somewhere readable by the application. Make sure this file is readable, you can
use a filesystem explorer to verify the file, and as in my code above, display
the image in an ImageView in the application just to be sure it’s readable by
the application.
Create a directory called tessdata readable by the application (I used
/mnt/sdcard/tessdata). Place a language file (see above for the link) in this
directory (I have just tried the English one.)
When you initialize with .init(dir,lang), make sure the directory name
terminates in “/” (“/mnt/sdcard/” in this case) and the String lang
corresponds to the language file you put in the tessdata directory “eng” in
this case.
My test code is above, in summary:
TessBaseAPI api = new TessBaseAPI();
boolean ok = api.init(tessParentDir+"/", "eng");
if ( !ok ) {
Log.e("ocr","Failed to initialize api");
return;
}
File f = new File(testImg); // test image file including path.
if (f == null || !f.canRead() || f.length()<1 ) {
Log.e("ocr", testImg+ " is not readable");
} else {
Log.i("ocr", "Trying to read file");
Pix px = ReadFile.readFile(f);
api.setImage(px);
Log.i(“ocr”,"File read");
String text = api.getUTF8Text();
Log.i(“ocr”,"Text is >>>" + text + "<<<");
}
In my experience, this will only work on the emulator with some versions of
Eclipse. However, it seems to work on a real device, at least on my Nexus One.
It took me a long time to get it work. Defensive programming, i.e. checking
success/failure after each operation, is essential in tracking down where it
goes wrong.
This discussion would suggest that a Tesseract/Android forum would be a welcome
addition. I hope someone can create one.

Ian

The owner of the project didn't put the latest version of the sources in the
download section.
You can get the latest version of the project with a svn checkout
http://tesseract-android-tools.googlecode.com/svn/trunk/
For Windows and to build Android 2.2 app :
1/ downloaded the ndk & tesseract tools (svn) project with the README
2/ build it on debian(vmware) with the ndk
3/ tesseract tools is actually a library and has a eclipse .project so just
import that project after building the so's with ndk and build it.
4/ Set it as lib :
http://developer.android.com/guide/developing/projects/projects-eclipse.html#Set
tingUpLibraryProject
5/ Now in the same workspace create a new android project i.e. your app. Go to
properties and reference the library from step 3
(http://developer.android.com/guide/developing/projects/projects-eclipse.html#Re
ferencingLibraryProject)
6/ Build your app based on Android 2.2 (min) :
http://code.google.com/p/tesseract-android-tools/issues/detail?id=5#c16
And it should work !

Hi,
check your ReadFile.java. If 2.2 or below you are not supposed to get this
error. It will go to the else part in the below code.
public static Pix readFile(File file) {
if (file == null)
throw new IllegalArgumentException("File must be non-null");
if (!file.exists())
throw new IllegalArgumentException("File does not exist");
if (!file.canRead())
throw new IllegalArgumentException("Cannot read file");
// TODO Fix support for JPEG library in Android 2.2 & lower
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.FROYO) {
final int nativePix = nativeReadFile(file.getAbsolutePath());
if (nativePix == 0)
throw new RuntimeException("Failed to read pix from file");
return new Pix(nativePix);
} else {
final BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inPreferredConfig = Bitmap.Config.ARGB_8888;
final Bitmap bmp = BitmapFactory.decodeFile(file.getAbsolutePath(), opts);
final Pix pix = readBitmap(bmp);
bmp.recycle();
return pix;
}
}
it will be in this fashion. and I think you are using some older version of
tesseract android tools.
You can get the latest version of the project with a svn checkout
http://tesseract-android-tools.googlecode.com/svn/trunk/

boolean ok = api.init(Environment.getExternalStorageDirectory() + "/", "spa");
if ( !ok ) {
Log.e("ocr","Failed to initialize api");
return;
}
File f = new File(Environment.getExternalStorageDirectory() +
"/tessdata/eurotext.jpg"); // test image file including path.
if (f == null || !f.canRead() || f.length()<1 ) {
Log.e("ocr", f + " is not readable");
} else {
Log.i("ocr", "Trying to read file");
Pix px = ReadFile.readFile(f);
api.setImage(px);
Log.i("ocr","File read");
String text = api.getUTF8Text();
Log.i("ocr","Text is >>>" + text + "<<<");
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText(text);

Hi, thanks for the reply.
The image is a jpg file, I converted it on my computer and copied it to my
sdcard.
I also tried the digits.jpg file that you can find earlier in this post.
It definitely seems an android version problem, I successfully executed the
application on a 2.3 emulator.
It's weird since the target version on the AndroidManifest states 8 as min sdk
version.

Hi,
First of all, what I'd do is, instead of referring directly to the sdcard
directory try Environment.getExternalStorageDirectory() just to be sure it's
getting the right path.
In my case it would only work with jpg images and as I mentioned before, I
would get the same error "Failed to read pix from bitmap" unless I executed it
in a 2.3 sdk version emulator.
I hope I helped.

Hi all. The problem might be solved. Since lib won't read files on Android 2.2
and I didn't like the process of saving files to SD card, I found a workaround:
convert Bitmap to 8bpp picture. Since I don't have knowledge of image
manipulation, someone has to do it properly. Here is code that accepts only one
color from 4 bytes per pixel image:
Drawable d = getResources().getDrawable(R.drawable.hello);
Bitmap bmp = ((BitmapDrawable)d).getBitmap();
byte[] store = new byte[bmp.getWidth()*bmp.getHeight()*4];
ByteBuffer buffer = ByteBuffer.wrap(store);
bmp.copyPixelsToBuffer(buffer);
byte[] bmpData = new byte[store.length/4];
int c = 0;
for (int i=0; i<store.length; i++) {
if (i%4==1) {
bmpData[c] = store[i];
c++;
}
}
TessBaseAPI tess = new TessBaseAPI();
boolean ok = tess.init("/sdcard/", "eng");
if (!ok) {
Log.e("TEST", "TESS DICT FAILED");
}
tess.setDebug(true);
Pix px = ReadFile.readBytes8(bmpData, bmp.getWidth(), bmp.getHeight());
tess.setImage(px);
String str = tess.getUTF8Text();
And it works on a simple image ;)
Hope this helps.

I think you have probably reached the limit of Tesseract, at least on Android.
I have found that the image needs to be extremely clear for Tesseract to make
sense of it, otherwise you just get a lot of junk as you have described. For
example, I cannot get Tessseract to scan successfully the attached image. It's
a bit disappointing :-(

tesseract expects uncompressed image. You'll get garbage if you're sending it a
compressed image (like the jpg you've attached)
Original comment by [email protected]

If tesseract requires an uncompressed image, why then does it support jpeg? As
detailed above, since the Android implementation doesn't work with bitmaps,
there's no alternative. (Setting the jpeg quality in the camera parameters with
setJpegQuality(100) doesn't help.)
