App crashes on loading library after upgrade to 1.6.2 and apriltag 1.1.1 about easyopencv HOT 12 CLOSED

Well that is..... puzzling 🐽

The key bit here seems to be

dlopen failed: cannot locate symbol "_ZN2cv3MatD1Ev" referenced by
"/data/app/com.qualcomm.ftcrobotcontroller-1/lib/arm/libEasyOpenCV.so"...

The symbol looks to be an OpenCV one.... are you using the default transitive dependency on 'org.openftc:opencv-repackaged-bundled-dylibs:4.5.3-C', or are you perhaps using a custom built version of the OpenCV native libraries?

from easyopencv.

Also what hardware are you running on?

from easyopencv.

We used to run a custom build long ago, but we've been running EasyOpenCV for the last two seasons. When we revert to 1.5.2 the pipeline works.

Here's what the module dependencies look like:

This is running on a chub with current OS and firmware, and with a Logitech C920 webcam

from easyopencv.

TeamCode build.gradle looks like:

apply from: '../build.common.gradle'
apply from: '../build.dependencies.gradle'

android {
namespace = 'org.firstinspires.ftc.teamcode'

packagingOptions {
    jniLibs.useLegacyPackaging true
}

}

dependencies {
implementation project(':FtcRobotController')
implementation 'org.openftc:easyopencv:1.6.2'
implementation 'org.openftc:apriltag:1.1.1'
annotationProcessor files('lib/OpModeAnnotationProcessor.jar')
implementation 'org.apache.commons:commons-math3:3.6.1'
implementation 'com.acmerobotics.roadrunner:core:0.5.6'
}

from easyopencv.

Can you test 1.5.3?

from easyopencv.

Exact same problem with 1.5.3 as with 1.6.2

from easyopencv.

Happy to setup a screenshare of the dev system if that helps.

from easyopencv.

That's very strange because I know multiple people using the latest versions without issue. I might build you an APK that I can prove works on my end and see what happens for you.

from easyopencv.

Please run adb shell pm uninstall com.qualcomm.ftcrobotcontroller

Then try this APK: https://drive.google.com/file/d/14qeWI9PhAZG9I9SZmQderh9UJf-5ARtM/view?usp=share_link

I tested that this APK runs correctly on a Control Hub with a C920 camera.

from easyopencv.

Oh and if that APK still crashes, then I'd probably suggest trying to factory reset the control hub.

@IronReignRobotics Were you able to test?

from easyopencv.

Closing due to no response. Feel free to re-open if you still have this issue.
