Google Play: java.lang.UnsatisfiedLinkError: org.bytedeco.javacpp.avutil #2 - P8 Lite

[anonym24]

I tested my app on some devices (cpu arm64-v8a or armeabi-v7a) , everything works ok with javacv ffmpeg libs

I also uploaded my app on Google Play Console (closed alpha version).

Google Play Console generates Pre-launch report for every app version

Here what I got

One device failed (Huawei P8 Lite) but I don't understand why, if javacv ffmpeg wasn't correctly set-up in my project then all devices would fail (my own and Google ones)

My app project includes:

javacv/cpp/ffmpeg-3.2.1-1.3

jniLibs

libs (project/app/libs)

build.gradle

...
        ndk {
            abiFilters 'armeabi-v7a', 'x86'
        }
...
...
dependencies {
    ...
    compile files('libs/ffmpeg-platform-3.2.1-1.3.jar')
    compile files('libs/javacpp-1.3.3.jar')
    compile files('libs/javacv-1.3.3.jar')
    compile files('libs/ffmpeg-3.2.1-1.3.jar')

# end javacv

So everything is set-up correctly 100%, so I don't need to look at #133 (I already read it many times), it seems some sort of specific issue here with this P8 Lite device

If someone have a suggestion what could be a problem or maybe even have such device (P8 Lite) and could test it?

Make sure to use ReLinker:
https://github.com/bytedeco/javacpp-presets/wiki/The-UnsatisfiedLinkError-X-File-%28a-real-experience%29
This usually works around that kind of issue.

Do I have to do this only for .so files (\app\src\main\jniLibs\armeabi-v7a) ? Then which order I have to use with ReLinker for next .so files?

ReLinker.log(logger).recursively().loadLibrary(context, "?");
ReLinker.log(logger).recursively().loadLibrary(context, "?");
...

my list without "lib" and ".so":

avcodec
avformat
avutil
jniavcodec
jniavformat
jniavutil
jniswresample
jniswscale
swresample
swscale

Do I also need to use it for jar files (\app\libs)? Or only for .so files?

p.s. I also cannot find/import org.bytedeco.javacpp.logger.debug :

[saudet]

What do you mean by "find/import"? Are you getting error when calling System.setProperty("org.bytedeco.javacpp.logger.debug", "true")?

[anonym24]

@saudet I just didn't know how to set it

anyway I just tried this order and it worked:) (all test devices on Google Play worked):

    ReLinker.log(logger).recursively().loadLibrary(this, "jniavcodec");
    ReLinker.log(logger).recursively().loadLibrary(this, "avcodec");
    ReLinker.log(logger).recursively().loadLibrary(this, "jniavformat");
    ReLinker.log(logger).recursively().loadLibrary(this, "avformat");
    ReLinker.log(logger).recursively().loadLibrary(this, "jniavutil");
    ReLinker.log(logger).recursively().loadLibrary(this, "avutil");
    ReLinker.log(logger).recursively().loadLibrary(this, "jniswresample");
    ReLinker.log(logger).recursively().loadLibrary(this, "swresample");
    ReLinker.log(logger).recursively().loadLibrary(this, "jniswscale");
    ReLinker.log(logger).recursively().loadLibrary(this, "swscale");

p.s. also we can remove or comment this line in proguard file (https://github.com/bytedeco/javacv/wiki/Configuring-Proguard-for-JavaCV):

# -keepattributes *Annotation*, Exceptions, Signature, Deprecated, SourceFile, SourceDir, LineNumberTable, LocalVariableTable, LocalVariableTypeTable, Synthetic, EnclosingMethod, RuntimeVisibleAnnotations, RuntimeInvisibleAnnotations, RuntimeVisibleParameterAnnotations, RuntimeInvisibleParameterAnnotations, AnnotationDefault, InnerClasses

it works ok without it, so we don't have to try to keep so much

[saudet]

Awesome, thanks for the report!
