@dannyball710 Looks like this line is triggering the both crashes: https://github.com/adaptech-cz/Tesseract4Android/blob/48429cbfeaf650944d57e51590c190a702cd1373/tesseract4android/src/main/cpp/tesseract/src/src/ccmain/pagesegmain.cpp#L103 So `pix_binary_` is null. Are you sure the bitmap you are giving to Tesseract is valid? When you are...

@dannyball710 Is it possible that you send the non-null bitmap to Tesseract, but before it has chance to process it, you call bitmap.recycle() somewhere else in the code? Or maybe...

I'm closing this as it has been without actionable response for some time. If you still have this problem and think it is caused by bug in the library, or...

@daniel-stoneuk Perhaps you can close this issue as it was merged?

@daniel-stoneuk Aha, I saw on the MaterialPreferenceLibrary notice that that library is deprecated now as it was merged to MAL. And can you be more specific? What kind of performance...

Also, I'm comparing the changes between your branch and master and I noticed some weird things: - why is there new INTERNET permission in AndroidManifest? // EDIT: I see, it's...

@daniel-stoneuk I pushed some fixes for the preferences branch.

@daniel-stoneuk As I now tried it, the bad performance during scrolling really seems to be caused by the nested RecyclerViews - it can be seen when you scroll down slowly,...

Hmm, maybe the scrolling issues are also caused by the DiffUtil, as it seems it freezes a bit for me always when new card should be added/drawn for first time...

@qinxianyuzou Does your `testOCR` directory contains subdirectory called `tessdata` in which are the `*.traineddata` language files? If you have language files directly in `testOCR`, it won't work.
