In preparation for google play 64 bit requirement I updated my project to include arm64-v8a libs. So now I have both armeabi-v7a and arm64-v8a folders inside Android/jni/ folder.
I use Clang Qt 5.12.4 for Android ARMv7 and Clang Qt 5.12.4 for Android ARM64-v8a kits for it’s respective builds.
The issue now is that only the 64 bit version works. Even when I use armeabi-v7a for building, it ends up with the following errors trying to look for arm64:

All android files are handled by gradle, now I’m not well-versed with gradle, but I assume it should handle which abi to use based on the kit used to build?
If I remove arm64-v8a from the filter the 32-bit app will work, but then the 64-bit one doesn’t. build.gradle:
android { … defaultConfig { minSdkVersion 19 ndk { abiFilters “armeabi-v7a”, “arm64-v8a” } } sourceSets { main { manifest.srcFile ‘AndroidManifest.xml’ java.srcDirs = [qt5AndroidDir + ‘/src’, ‘src’, ‘java’] aidl.srcDirs = [qt5AndroidDir + ‘/src’, ‘src’, ‘aidl’] res.srcDirs = [qt5AndroidDir + ‘/res’, ‘res’] resources.srcDirs = [‘src’] renderscript.srcDirs = [‘src’] assets.srcDirs = [‘assets’] jniLibs.srcDirs = [‘libs’, ‘jni’] } } … }
Has anyone encountered a similar issue or has any idea how to make it build only the libs for the kit I’m using? I don’t really understand why it’s looking for 64-bit libs when building with Clang Qt 5.12.4 for Android ARMv7.
