Android build failing before launch

[Cozmoz]

I've recently updated Android Studio and am now having the following error output on build, I am running the latest Android SDK Build-Tools 36-rc5, Android SDK Command-line Tools and CMake. I also have Android Emulator, Android Emulator hypervision driver, Android SDK Platform-Tools, Google Play services, Google Repository and SDK Patch Applier v4 installed. Any help would be appreciated.

This suggest that gradle cannot make a secure https connection.

Reasons why that may be (in the order of likeliness):

1. I think Java might include its own certificates as well, so out-dated JDK could also be a problem. Latest android environments requires JDK 17, so you should double check that you have the latest patch of JDK 17 installed.
2. Your OS is out of date and doesn't have the latest intermediate certificates
3. VPN is manipulating the connection and is preventing a proper handshake
4. HTTP proxy is manipulating the connection and is preventing a proper handshake

The nature of the error makes it difficult to pinpoint the exact cause, but it is a client side environment issue.

Build-Tools 36-rc5

This isn't your issue at hand but will be an issue later. Build Tools 36 is currently not supported. cordova-android@13 will expect the latest version of build tools 34. cordova-android@14 (not yet released) will expect the latest version of build tools 35.

Thanks for the prompt response Norman, I've updated my software as follows:

• Android Studio Meerkat Feature Drop | 2024.3.2 Canary 6
• Gradle 8.13
• Java 8
• Java SE Development Kit 23.0.2

I am not running a VPN, am running an up to date version of Windows 11 and am getting the following error:

If you can recommend software versions that work together I would happily uninstall what I have and start fresh. Thanks.

This indicates that you're running JDK 23. Android SDK requires JDK 17 as I mentioned in an earlier post. Android SDK tends to lag behind in support quite significantly over the newer bleeding edge java.

so you should double check that you have the latest patch of JDK 17 installed

To be more clear, I meant to ensure you're using the latest patch/minor release of JDK 17. e.g. if you were had JDK 17.0.0, when JDK 17.0.14 is available, that could resolve issues. I did not mean to upgrade to a newer JDK major release if you were already using JDK 17.

To resolve this issue, you'll need to downgrade to JDK 17. If you need JDK 23 for something else on your workstation, you can have both installed simultaneously and use CORDOVA_JAVA_HOME environment variable to make cordova use JDK 17. CORDOVA_JAVA_HOME if set will take priority over JAVA_HOME when using the Cordova command line tool.

Thanks, that worked.
