I encountered the same problem you got,please let me know if you solve it

[c1rew]

I don't know the really problem is, and after modify many source code file can not solve this crash.

but I found a bug, maybe it is the point.

source code file jni/src/core/ImageProc.cpp
line 64 str = plateVec[0];
if input image have not plate, vector plateVec will be empty, that will be crash.

I think this will help you.

after few days , I will update this project to latest EasyPR and fix this crash on my own page.

@dylanchann I've just change the 63rd line of source code file jni/src/core/ImageProc.cpp:
if (count == 0) to
if(!plateVec.empty() && count == 0)
hope it helps .
