Javacv: INSTALL_FAILED_INVALID_APK with 1.5.2

[UpAndDownAgain]

Im trying to use FFmpegFrameGrabber in Android but when I try to install i get the INSTALL_FAILED_INVALID_APK error.
I start with empty project then add ffmpeg.jar, ffmpeg-android-arm.jar, javacpp.jar, javacv.jar into app/libs then add those as jar dependencies in project structure

I'm using android studio 3.6.1
Thanks for help

There should be more details about why it's "invalid". Please show all the information that it provides.

So the error I was getting was caused by failing to extract native libraries which is fixed by adding

android:extractNativeLibs="true"

into androidManifest.xml into application section. It might be useful to add this into readme in case others run into the same issue
