QUESTION
SO After being an iOS Developer for 8 and half years , I started learning andorid 4 months ago and I was given a Cordova andorid project to work on. Task was to integrate Fingerprint and face ID Login.
What i have in my current project ( very old project ) :
build gradle : 2.3.3 gradle version : 3.3 cordova-android version : 5.1.4
I know these are very old .
What i tried so far in last 10 days :
I tried to upgrade above to latest build gradle and gradle version. Whole bunch of errors appears , one after another.
I have tried adding bio-metric support library in build.gradle and in build-extra.gradle one by one .. but nothing works...
My Qustions:
Why cant i add bio-metric support library When i have everything compile and work fine on build gradle 2.3.3 and gradle 3.3 ?
Do i have to update gradle and every support library version to latest ? If yes then will it cause issues in code ? Lets say i have used Any old UI component which wwill generate compile time errors when i try to merge old support libraries with new biometric API. I tried it.
Can anyone just tell me the step by step of upgrading this project so that even there are compile time errors i can remove those and then once everything works fine i can add biometric support library.
Lastly Biometric support libraries can be integrated into any old project , thats why they are called support libraries. Correct me if i am wrong.
I am using Android studio on MAC OSX

QUESTION
I am still confused about how to build a working tess-two Android Studio project for using Tesseract OCR, despite several posts on it. There is a pre-built version available, whose "Usage" section of the "ReadMe" says we can do this by simply adding tess-two as an external dependency by just adding the following line to the dependencies section of our app's build.gradle:
ANSWER
Answered 2017-Jul-16 at 15:23In addition to the compile line added to the dependencies section of my app's build.gradle, do I also have to copy the tess-two folder (or some parts of it) into my main app's root directory?
No. By adding that compile line to your build.gradle, you're importing a compiled version of that library's code into your project, and there's no need to also copy its source code into your project.
You can confirm this yourself by creating a new project in Android Studio, adding the compile line for the library to your new app's build.gradle, and then adding a line of code to your new activity's onCreate method that references a class in the library:
QUESTION
I am using Tess-Two for creating an OCR for Android. I used the same image for conversion, but the result is very different from the tesseract for desktop.
The desktop version of tesseract gives a better result.
I am using the following lines on Android:
...ANSWER
Answered 2019-Aug-19 at 13:14So as I commented on your post and just solved it for me, I thought I share.
The first problem for me was that the image needs to be preprocessed for better results. I'm using OpenCV for the preprocessing. Here https://android.jlelse.eu/a-beginners-guide-to-setting-up-opencv-android-library-on-android-studio-19794e220f3c is a good example how to set it up.
Then the image needs to be switched into a binary image. For me the following gives best results

QUESTION
we are parsing an image showing a textsnippet which has a resolution of 2121x105 px. In Java we have the following code to get an byte array (one of our constraints is to work with a byte array here):
...ANSWER
Answered 2018-Aug-01 at 10:31tess-two which uses tesseract OCR expects decoded image in rgba rgb or gray format.
So you need to decode your png (this question explains how to do it in java) and convert result to byte array.
bpp is bytes per pixel for rgba format it would be 4 (1 byte is red 2 is green 3 is blue 4 is alpha) for rgb it would be 3 (1 byte is red 2 is green 3 is blue) for grayscale it would be 1.
bpl is bytes per line = bpp * image width
QUESTION
I am not much of an expert.I am using tesseract (tess-two) for developing an android application for my college project. The application crashes when I select the Nepali trained data.
*The application works only with Image selected from gallery. The image taken from camera returns empty result. So, yes! I am in big trouble here!!
Here is the snippet of the LogCat when I used eng.trainddata:
...ANSWER
Answered 2018-May-04 at 15:17So the other thing I had done wrong was the value of dataDirectory and just changing its value made the application a lot stable. The nep.trained data was found and initialized by the tesseract after that.
