Crash during EU recognizing

[Lasek]

Hey, I use sample application. I changed us to eu but app was crashed during plate recognizing.

String result = OpenALPR.Factory.create(MainActivity.this, ANDROID_DATA_DIR).recognizeWithCountryRegionNConfig("eu", "", destination.getAbsolutePath(), openAlprConfFile, 10);

Log:

Probably this is related to #1and should be fixed now, can you please test with the version 1.0.1?

[Lasek]

I tested with 1.0.1 version. Issue still exists.

I have the same issue

[SandroMachado]

I tried with a Portuguese licence plate and it worked as expected (please check the screenshot above).

Probably the problem was that the library was not able to recognize any licence plate in the picture. I improved the sample application (https://github.com/SandroMachado/openalpr-android/commit/e1037941f4f7dba1bd74ef24b0833ccfd8fd6e18) to display a toast instead of crashing when the library is not able to recognize any licence plate.

Same issue here with v1.1.0.

Same picture works with "us" and doesn't with "eu". Tested with sample app on two different devices.

Fortunately I was able to get rid of this SIGSEGV! All i did was adding the new folder in assets of the library: main/assets/runtime_data/keypoints/eu I also copied there one of the files from "us" folder.

Already made few tests that were producing the crash before - now wasn't able to reproduce the problem!

Fixed by #9.
