Android Development Questions—JDK and Presplash/Downloading images

[limpciabatta]

Hi, I've been trying to figure out what I need/how I should go about exporting my Ren'Py project as an Android app that users can play on their Android devices, and after reviewing the documentation here (https://www.renpy.org/doc/html/android.html#android), I have a few questions, primarily about the Java Development Kit and the presplash/downloading images. If you're able to help provide some clarity for me on these topics, I'd greatly appreciate it!

1: To start, I've downloaded the Java Development Kit found here: https://adoptium.net/ —I'm using a mac and downloaded Temurin for macOSx64. However, the Ren'Py documentation says that I need version 8 of the JDK (here: https://adoptopenjdk.net/releases.html? ... nt=hotspot)—is this just something in the documentation that needs to be updated to reflect the latest updates of the JDK, or should I find a way to download OpenJDK 8?

2: I downloaded Temurin for macOSx64 to my downloads folder, and then I've gone into the Ren'Py launcher>Android and selected Install SDK & Create Keys. However, I receive the following error message:

Code: Select all

I'm sorry, but an uncaught exception occurred.

Am I getting this error because I'm using a wrong version of the JDK, the JDK wasn't installed in the correct folder, or is this due to another issue? And any advice on how to resolve this error?

3: Presplash and downloading images—is there any guidance on the sizes these images should be? I'm using the 2560x1440 screen dimensions for my game development, so would it be safe to assume that I should use those dimensions for these images, too?

Thank you so much, I really appreciate any help you're able to provide on these!

Ren'Py (currently) specifically required version 8, yes. Other versions will not work.

Groovy, thanks! I've deleted the version of the JDK I previously downloaded and downloaded JDK8, although I'm still getting this error:

Upon further research/looking for instances where others have encountered the same error, I think it looks like I either don't have the JDK8 installed correctly/in the correct place, or I might need to set the JAVA_HOME system variable? I'm not sure how to do either of these (I'm using macOS Sonoma 14.1) though—are there any specific steps I can follow?

Thanks!

I'm sorry, I have no experience with macs, my last interaction with one being over 2 decades ago.

I don't recognise the bug you are experiencing
