I have tried to copy the tesseract 4 inside the /home/m/tess/tess-two/jni/com_googlecode_tesseract_android/src tess-two to compile it with the ndk-build for Android. But I got these result:

jni/com_googlecode_tesseract_android/tessbaseapi.cpp:550:31: error: assigning to 'PROGRESS_FUNC' (aka 'bool ()(int, int, int, int, int)') from incompatible type 'bool (void , int, int, int, int, int)': different number of parameters (5 vs 6) monitor.progress_callback = progressJavaCallback; ^~~~~~~~ jni/com_googlecode_tesseract_android/tessbaseapi.cpp:553:11: error: no member named 'progress_this' in 'ETEXT_DESC' monitor.progress_this = nat;

Thanks for the report. We're tracking Tesseract 4 efforts on https://github.com/rmtheis/tess-two/issues/196
