Android Build Tools only builds x86_64 no matter what. APK runs installed via adb, but shows incompatible on Play Store

So this is happening. No matter what I try doing on the build.gradle, all APK are coming out with `native_code = 'x86_64'` flag, so when I deploy the app to the store the result is having +15K uncompatible devices, and only 19 compatible. I first thought that, somehow, having NDK installed was the reason, or my modified build script. But it still happens when I go through the Generate Signed APK wizard. The `splits` block was also originally missing, and didn't help. The weirdest thing is that when I install via a console push, IT WORKS! I also tried switching to the recommended JRE, also several APK naming strategies regarding file creation, like moving the output to different directories or not using the file constructor. My `build.gradle` looks like this: ``` defaultConfig { applicationId "com.chiskosystems.brokr" versionCode versionNumber versionName "${versionMajor}.${versionMinor}.${versionPatch} (${versionBuild}) Release" minSdkVersion 16 targetSdkVersion 25 testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" multiDexEnabled true jackOptions { enabled false } vectorDrawables { useSupportLibrary true } } splits { abi { enable true reset() include 'armeabi', 'armeabi-v7a', 'arm64-v8a' } } project.ext.versionCodes = ['armeabi': 1, 'armeabi-v7a': 2, 'arm64-v8a': 3] applicationVariants.all { variant -> variant.outputs.each { output -> def fileNaming = "apk/brokr" def outputFile = output.outputFile output.versionCodeOverride = project.ext.versionCodes.get(output.getFilter( com.android.build.OutputFile.ABI), 0) * 10000000 + android.defaultConfig.versionCode } } signingConfigs { release { try { storeFile file('../mystore.jks') keyAlias 'release' storePassword KEYSTORE_PASSWORD keyPassword KEY_PASSWORD } catch (ex) { throw new InvalidUserDataException("You should define KEYSTORE_PASSWORD and KEY_PASSWORD in gradle.properties.") } } } dataBinding { enabled true } dexOptions { javaMaxHeapSize "3g" preDexLibraries false } buildTypes { release { minifyEnabled false proguardFile 'path/proguard-project.pro' ... buildConfigField "String", 'SERVER', '"https://myfirebaseserver.com"' debuggable false signingConfig signingConfigs.release } debug { minifyEnabled false applicationIdSuffix ".debug" versionNameSuffix "-debug" buildConfigField "String", 'SERVER', '"https://myfirebaseserver.com"' } } compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 } productFlavors { sandbox { buildConfigField "String", 'PAYPAL_ENV', '"PayPalConfiguration.ENVIRONMENT_NO_NETWORK"' } full { buildConfigField "String", 'PAYPAL_ENV', '"PayPalConfiguration.ENVIRONMENT_PRODUCTION"' signingConfig signingConfigs.release targetSdkVersion 25 } } ``` Happening on both Win and Unix systems. I've spent the whole day modifiyng the script without success and I'm helpless at this point. Any ideas of what the bleep is going on? Thanks a lot!
