I'm trying to run a ANPR project downloaded from http://code.google.com/p/android-anpr/source/.

When I try to execute it, the app is closing immediately.

I tried to debug it, but it looks like the problem comes from NativeGraphics.yuvToRGB(data, preview.cs.width, preview.cs.height);, and I can not figure out why exactly.

Would be really great if someone could take some time and try to run it and and discuss the error with me. In my opinion, there are some missing libraries or wrong implementation.

  • Please read the [FAQ](http://stackoverflow.com/help/how-to-ask) about how to ask. You should provide the experts some more hints e.g. the error message. –  Jul 01 '13 at 11:07
  • @user2538472,did you successfully executed the above source in android? If so let me know, i'm facing issue in these. – Senthil Mg Apr 23 '14 at 14:27

I had the same issue - try changing your toolchain for the NDK. I believe it is set to arm-linux-androideabi-4.6 by default, but if you change it to arm-linux-androideabi-4.8 it should work.

  • Did you successfully executed the android-anpr src from code.google.If so help me to resolve the problem i am facing on it. – Senthil Mg Apr 23 '14 at 14:23

You may want to check out OpenALPR (http://www.openalpr.com). It should compile under the NDK and would give you more accurate readings. It's probably a bit faster as well.

I was having similar trouble; By the way there's information in the log, but it does not show up as an error nor does it show up as related to the app.. you really have to pay attention. The short version, for me, was this: There's a bit of assembly code in graphics_core.cpp that requires you to have a NEON-capable ARM core. The log messages say mine is, but a SIGSEV happens somewhere in there so I'm not convinced the assembly code is correct (seems to be reading memory it does not own). Thankfully there's an easy way around this: In GraphicsCore :: yuvToRGB replace:

#ifdef __ARM_NEON__

with:

#if 0

and the code in the else branch will be used instead. I've yet to get it to properly recognize any plate yet but it doesn't recognize plates in my region at all so I'm not going to be looking further into it.

By the way, the log messages look something like this:
