Unsupported usage of main-dex list. The usage of main-dex-list content for the compilation of non-DEX inputs is deprecated.

Strange error when compiling. It happens on one of my laptops only, on the other it works well. The files are identical in both laptops and both have the same Java version and Adobe AIR SDK version.

That dx tool failed output sounds like it's using the "legacy" build mechanism - which wouldn't work with later Android build tools or SDKs. So it may be there's a difference in the Android set-up between the machines..

You may be able to tell more from the adt.log file (or simpler - use the AIR SDK Manager and the 'Troubleshooting' tab) but I would suggest trying to use the newer Gradle-based build mechanism, which should kick in automatically if you set up the Android platform SDK and have an app descriptor namespace of 33+..

thanks

@ajwfrost

I downloaded AIR SDK from here: https://airsdk.harman.com/download

And I have simply been using the command line. Where may I find the AIR SDK Manager and the adt.log file?

[marchbold]

Have a look on the airsdk site: https://airsdk.dev

I am not sure how to use the newer Gradle-based build mechanism. The steps that I am taking for this are the following:

1. Remove <BuildLegacyAPK>true</BuildLegacyAPK> from application.xml.
2. Add the following to adt.cfg:

AndroidPlatformSDK=C:/Users/david/AppData/Local/Android/Sdk
JAVA_HOME=C:/Program Files/Java/jdk-21

I have Android Studio 2024.2.2 installed, with the Android 15 SDK and Gradle 8.10.2. I want the apk to work in this Android version.

Then I get the output:

ADT 51.1.3.5 called with: -package -target apk -storetype pkcs12 -keystore hfx.p12 HeroFighterX_FullVer.apk application_fullver.xml -extdir extensions HeroFighterX_FullVer.swf _Pic_Gen

Target requested was apk-captive-runtime, but not using legacy APK so building via Android Studio

Creating device SDK handler - location passed in = C:\Users\david\AppData\Local\Android\Sdk

NOTE: Multiple Android build-tools folders exist, choosing the latest version (35.0.1) for packaging

Version in APK = 51.1.3.5, version of ADT = 51.1.3.5

NOTE: targets later than Android 33 need Gradle Plugin versions of 8 or more. Adjusting to 8.1.1

Any help would be appreciated.

Okay so you've managed to change it so it's building via Gradle, which is great .. but it looks like you have the Android 35 platform installed; we are adjusting from our default to use the Android Gradle Plug-in 8.1.1 but I think we're likely still using an older Gradle version, which isn't compatible with Java-21.

A few options maybe - I don't know that it would help but potentially using Java 17 may help? - but otherwise, assuming you don't want to downgrade your environment's Android platform installation, it may be worth adding a flag to your application descriptor file to ensure you use a later Gradle version too.

For Android-35, you could try having:

<android>
     <androidGradlePluginVersion>8.8</androidGradlePluginVersion>
     <gradleVersion>8.10.2</gradleVersion>
</android

or 8.7 + 8.9, or other combinations from https://developer.android.com/build/releases/gradle-plugin#updating-gradle

Using Java 17 has allowed the apk to compile. However I cannot install it in Bluestacks, whereas the legacy build works. Attempting to install it in the Android emulator gives the following error:

Error running 'HeroFighterX_FullVer' The application could not be installed: INSTALL_FAILED_NO_MATCHING_ABIS Installation failed due to: 'Error code: 'INSTALL_FAILED_NO_MATCHING_ABIS', message='INSTALL_FAILED_NO_MATCHING_ABIS: INSTALL_FAILED_NO_MATCHING_ABIS: Failed to extract native libraries, res=-113'' List of apks: [0] 'C:\Users\david\ApkProjects\HeroFighterX_FullVer\HeroFighterX_FullVer. apk'

From your command line, it's leaving the APK with the default architecture/ABI (armv7) - I'm not sure which architecture Bluestacks needs, it sounds like it can support all of them but is there any way you can check this?
https://support.bluestacks.com/hc/en-us/articles/360058929011-What-is-Application-Binary-Interface-ABI-in-BlueStacks-5

You could try adding the -arch x64 option perhaps, to generate an x86_64 version? Or you could use -target aab to package up an Android App Bundle which contains all of them; if you use ADT to install this onto the BlueStacks emulator, the tools should automatically pick the right architecture.

Plus - it might also be worth opening the APK file with a zip editor and making sure it looks okay, with an AndroidManifest.xml file in the root folder and a lib/armeabi-v7a/libCore.so native library folder (which is what Bluestacks is rejecting).

thanks
