What causes this Android APK Upload error: “Non-upgradable APK”

Question

I have an Android APK in the Google Play store with an Target SDK of 23.

I have released a new version (same target SDK) and Google shows me this error:

If I

Answer 1

I just had the same issue with the versions, as I upgraded react-native to 0.60.5 So I calculated the differences between missing versionCode version

Version 1.9 = VersionCode => 4194313

Version 1.10 = VersionCode = 3145739

Difference : 194313 - 3145739 = 1048574

Each APK per architecture will use that formula

versionCodes.get(abi) * 1048576 + defaultConfig.versionCode

I have modified a little bit my formula

versionCodes.get(abi) * 1048576 + defaultConfig.versionCode + 1048574

// applicationVariants are e.g. debug, release
applicationVariants.all { variant ->
    variant.outputs.each { output ->
        // For each separate APK per architecture, set a unique version code as described here:
        // https://developer.android.com/studio/build/configure-apk-splits.html
        def versionCodes = ["armeabi-v7a": 1, "x86": 2, "arm64-v8a": 3, "x86_64": 4]
        def abi = output.getFilter(OutputFile.ABI)
        if (abi != null) {  // null for the universal-debug, universal-release variants
            output.versionCodeOverride =
                    versionCodes.get(abi) * 1048576 + defaultConfig.versionCode + 1048575;
        }
