NativeScript Angular

NOTE: The recommended approach for reducing the app size by splitting it per architecture is the Android App Bundle which is supported out of the box through the --aab NativeScript CLI flag.

Android ABI split

If the recommended Android App Bundle approach is not applicable for you, an ABI split could be manually configured as an alternative. The ABI split approach will produce different apk files for the different architectures. To achieve this you need to enable ABI splits at app/App_Resources/Android/app.gradle

Enable ABI split

android {
  defaultConfig {
    ndk {
  splits {
    abi {
      enable true //enables the ABIs split mechanism
      reset() //reset the list of ABIs to be included to an empty string
      include 'arm64-v8a', 'armeabi-v7a', 'x86'
      universalApk true

Note: In order to get a maximum app size reduction, you can combine the Android App Bundle with a compiled V8 heap snapshot.

Publishing ABI split apk

Now you will need to upload all built apk files in Google Play Developer Console. To achieve this the different apks need to have different Version Codes otherwise Google Play won't allow adding them in the same version. To use different Version Codes you can add the following code in your App_Resources/Android/app.gradle which will prefix the different architecture apk Version Codes with different prefixes:

project.ext.abiCodes = ['armeabi-v7a': 1, 'arm64-v8a': 2, 'x86': 3]

android.applicationVariants.all { variant ->
    variant.outputs.each { output ->
        def baseAbiVersionCode = project.ext.abiCodes.get(output.getFilter("ABI"), 0)
        if (baseAbiVersionCode != null) {
            output.versionCodeOverride = baseAbiVersionCode * 10000000 + variant.versionCode
