Steps to reproduce the issue:

    mTessBaseApi = new TessBaseAPI();
    mTessBaseApi.setDebug(false);
    mTessBaseApi.init(mDataPath, mLang);

This is happening with signed apk, basically post uploading to Google Play. Issue is for only specific Native platform armeabi-v7a

Expected result:

OCR should scan the data and provide the expected results / output.

Tess-two version:

6.3.0

Android version:

Android 6.0

Phone/device model: Galaxy Note Edge (tblte) / Redmi 3S (land)

Phone/device architecture (armeabi, armeabi-v7a, x86, mips, arm64-v8a, x86_64, mips64):

Native platform armeabi-v7a

Thanks for reporting this. Do you have an input image for which this native crash happens consistently?

[SidhanshuUdawat]

Usually this happens when scanning McDonald's or KFC over the counter receipts. This crash is happening in all devices with Native platform: armeabi-v7a.

Do you have any idea how to fix this ?

@SidhanshuUdawat Short answer: No. The simplest way to investigate this crash would be to reproduce it.

Please provide an input image for which this native crash happens consistently, and a link to the training data file that you're using.
