Crash caused by missing libopenalpr-native.so

ZKjellberg commented 8 years ago

Testing your application and I am receiving a crash when submitting the image. This was tested using the Sample app source code from this repository on a Nexus 6 running Android 6.0.1.

This error occurs when depending on the source within Android Studio, which is very awkward as the repo is structured as two seperate Android Studio projects with relative path references that didn't seem to work for me until I merged them into one project.

I also tested using the JitPack release and received the same error. I did have issues with the JitPack dependency as Android Studio could not resolve the suggested aar with the transitive flag, but using the reference: compile 'com.github.SandroMachado:openalpr-android:1.0.0' compiled.

Sample image used: https://commons.wikimedia.org/wiki/File:AZ_1950_license_plate.JPG

It appears the issue is related to how I am handling the dependency for the project with the missing libopenalpr-native.so binary.

Hey @ZKjellberg

About the jitpack import error. With the transitve syntax it should work... but looks like it is not working, so I updated the README of the project with your suggestion. Thanks

Can you please confirm that merging the project you didn't miss the assets folder in the sample application?

I also generated an apkapp-debug.apk.zip, can you also please test with it and verify if the problem persists?

I also updated the master with a fix to the sample project be able to compile out of the box. Can you please fetch the lastest master commits and try to open the sample project with Android Studio from this folder.

Hi @SandroMachado

I just tried importing it straight from your master and the sample project you provided, I receive similar errors:

20187-22048/com.sandro.openalprsample E/AndroidRuntime﹕ FATAL EXCEPTION: AsyncTask #1 Process: com.sandro.openalprsample, PID: 20187 java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/com.sandro.openalprsample-2/base.apk"],nativeLibraryDirectories=[/vendor/lib64, /system/lib64]]] couldn't find "libopenalpr-native.so"

@SandroMachado I tested using your app-debug-apk.zip install. When I submit my picture, the application gets stuck on Parsing Result. In the logs, it appears there is an error.

Line 77 is the below item, oddly the variable in is labeled as never used.

FileInputStream in = new FileInputStream(destination);

Reviewing the application permissions, it appears the issue is you never ask the user for permission to use their storage. When the user manually enables this from the Settings page, the application successfully runs.

When compiling from the latest source code, I am still experiencing a crash searching for the binary:

ZKjellberg commented 8 years ago

Regarding the APK you released, the failure for Parsing Result to advance is because you target SDK 23 which assumes you implement the new Android 6.0's permission system. I am pushing up code which should resolve this issue. Feel free to change the workflow.

SandroMachado commented 8 years ago

Hey @ZKjellberg and @Bryanli910

I think I have finally found the issue. Can you please try again with the master latest code?

ZKjellberg commented 8 years ago

Tested, application is now working. Thanks for the fix.

SandroMachado commented 8 years ago

Great! Thanks for the help! I will make a release with this fix.

SandroMachado commented 8 years ago

Closed by 1.0.1.

Hey @SandroMachado I have a problem with the last version of your example project, it shows me the following error.

couldn't find "libopenalpr-native.so"

How can I solve this error?
