@sethshal Of course it matters. Please ask the Android team for information regarding your native platform, and let us know what you find! Thanks

For android, I wrote the build.gradle as below. Everything is good.

dependencies {
    compile group: 'org.bytedeco', name: 'javacv', version: '1.0'
    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '2.4.11-0.11', classifier: 'android-arm'
    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.6.1-0.11', classifier: 'android-arm'
}

hi Saudet, i'm facing same problem, i have updated both file javacv and javacpp from download from github, full zip 135 mb. I just copy "RecordActivity" to our example and try to use things but everything same issue reported.. App crash when i start recording. Showing me this logcat

[saudet]

@lfdversluis So, are you confident that your instructions on the wiki fixes all and every problem related to ProGuard, and we can close this issue? Let me know! Thanks

[lfdversluis]

@saudet I recall @sethshal having issues with it. I did not gain any errors but then again every architecture (and almost every phone) is different. I hope @sethshal can comment if he has issues or managed to fix them (and update the wiki if needed)

[sethshal]

I haven't worked on the project for a while. So I haven't had a chance to test any new build. The last I had tried it the app size was huge as I had to disable proguard. I had managed to reduce the app size a bit by removing so library files.

[Jamoke]

It was a long read. But I've read all the posts, and desperately need to get this working. I approached it skeptically, but the instructions on the wiki page were very helpful, and after adjusting the proguard settings manually, and following ALL of the instructions, I still get this error:

E/System: Uncaught exception thrown by finalizer
E/System: java.lang.NoClassDefFoundError: Failed resolution of: Lorg/bytedeco/javacpp/avcodec;

my build.gradle has:

dependencies {
    compile group: 'org.bytedeco', name: 'javacv', version: '1.1'
    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.0.0-1.1', classifier: 'android-arm'
    compile group: 'org.bytedeco.javacpp-presets', name: 'opencv', version: '3.0.0-1.1', classifier: 'android-x86'
    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.8.1-1.1', classifier: 'android-arm'
    compile group: 'org.bytedeco.javacpp-presets', name: 'ffmpeg', version: '2.8.1-1.1', classifier: 'android-x86'
}

I also tried previous versions of ffmpeg and openCV (2.6.1, 2.4.1, etc) which were stated to be working in this thread. My proguard-rules.pro file contains the instructions straight from the wiki today. ( https://github.com/bytedeco/javacv/wiki/Configuring-Proguard-for-JavaCV ) Again, the instructions were good, and appear to work, because before these settings were applied, I was getting duplicate symbols for including the ffmpeg library, as well as the ffmpeg x86, and ffmpeg arm libraries. So I think that certainly helps when compiling with Android SDK 23 build tools for multiple platforms. However I still get the error. I am running on a Galaxy S6 (which is Arm-64).

*Edit: I was wrong. It didn't compile correctly, and it was using a cached APK with the manaul copies of the JAR files for deploying to device. the compiler when I had the proguard settings, and the dependencies setup the error was:

What went wrong:

Execution failed for task ':app:transformResourcesWithMergeJavaResForDevDebug'. com.android.build.api.transform.TransformException: >com.android.builder.packaging.DuplicateFileException: Duplicate files copied in APK META->INF/maven/org.bytedeco.javacpp-presets/ffmpeg/pom.properties File1: /Users/[me]/.gradle/caches/modules-2/files-2.1/org.bytedeco.javacpp-presets/ffmpeg/2.8.1-1.1/e887e3cf952e0aa10212467c399d94a4daa78e2e/ffmpeg-2.8.1-1.1.jar File2: /Users/[me]/.gradle/caches/modules-2/files-2.1/org.bytedeco.javacpp-presets/ffmpeg/2.8.1-1.1/e9de6569f01f6546da3e51ea1315bb933a38e11c/ffmpeg-2.8.1-1.1-android-arm.jar *

**Edit 2: I fixed the duplicate file exception by adding:

packagingOptions { exclude 'META-INF/maven/org.bytedeco.javacpp-presets/ffmpeg/pom.properties' exclude 'META-INF/maven/org.bytedeco.javacpp-presets/ffmpeg/pom.xml' }

but now the gradle console output is throwing a new exciting error:

Execution failed for task ':app:transformClassesAndResourcesWithProguardForDevDebug'. java.io.IOException: Can't write ...../build/intermediates/transforms/proguard/dev/debug/jars/3/1f/main.jar (Can't read ......./org.bytedeco.javacpp-presets/opencv/3.0.0-1.1/[hash]/opencv-3.0.0-1.1.jar(;;;;;;*/.class) (Duplicate zip entry opencv-3.0.0-1.1.jar:org/bytedeco/javacpp/opencv_videostab$ColorInpainter.class)) **

*\ Edit 3: I had the jar files and the dependencies defined... Cost of trying to many options. I was able to get the compiler errors to go away, and it looks like everything is working now. As a note: I specifically did NOT need to update the proguard manually per the wiki. That in fact caused a myriad of problems... The proguard that ships with Android SDK / Android Studio now works fine.

Hi, I followed the wiki instructions but still got the ClassNotFoundException with difference stack trace output:

Don't know why such many .so libs were not found and ignored up there, which may cause the exception. Did I miss anything??

Thanks.

[Jamoke]

If the libraries are missing, then the proguard didn't run correctly... Did you follow the steps in this wiki document:

https://github.com/bytedeco/javacv/wiki/Configuring-Proguard-for-JavaCV

(P.S. - in regards to the "Upgrade your proguard in the Android SDK" I didn't need to replace my Proguard version. The one that came with Android SDK was new enough as of now [December 2015])

[crossmo]

@Jamoke thanks :) Yes, I did. I even disabled progard and failed with no locks.

[ShihabSoft]

Hope you got the correct dependencies in libs folder and try Project->Clean

try to change your classpath to classpath 'com.android.tools.build:gradle:1.2.3'
then clean and rebuild its in build.gradle (project: ) file the classpath of this example https://github.com/bytedeco/sample-projects/blob/master/JavaCV-android-example/build.gradle use classpath 'com.android.tools.build:gradle:1.2.3'

[vxhviet]

@Jamoke would you mind providing the steps to get this working? I've literally trying every possible methods provided but still haven't managed to get this working :'(

[saudet]

@Jamoke Could you update the instructions on the wiki page with your findings? Thanks a lot for testing this out!
