When I try to create an Android APK, I get this message.
What am I doing wrong ?
I use w11

I'm sorry, but an uncaught exception occurred.

It seems like it can't find a file, try reading through the words and taking a little time to digest the meanings.

I solved it but I have another problem.

When I try to compile for the apk to download all the tools with the app "the question" I get failure.

I cannot download the tools in the rapt folder,

the one that weighs 2.5 gb.

Are you using a VPN? Some will cause failures here.

I changed the DNS, and it worked.

Hi Wills747 !

I have used some of your SDKs to create android ports for some games and they work great. Thank you very much for your work.

I am looking to create a port for version 8.3.6 and a rather old version 7.3.5. Do you have SDKs for these versions?

I will donate to you, I promise!

8.3.6 should be 8.3.7 compatible?
7.3.5 I still have somewhere, I've modified rapt to still work after bintray shut down but it's otherwise stock.

Haven't tried it yet but let me see if it works.

7.3.5 I still have somewhere, I've modified rapt to still work after bintray shut down but it's otherwise stock.

I know this is quite old version, very few games still support it. But my customers really need games of this version. Do i have any test version of 7.3.5?

Every game that I do with that old of an SDK gets an upgrade

It works pretty well. Thanks a lot.
Btw, I just donated to you, as promised.

Hello, first of all - great work! Using your solutions to keep my players' save data in place.

With the new update, I used your Renpy 8.3.7 SDK. And some of my players on android 15 (and 14 too I believe) got this message:

Unsafe app blocked

This app was built for an older version of Android and doesn't include the latest privacy protections.

Installing this app may put your device at risk. Learn more about Play Protect.

And while they can click "Install anyway" without problems, can this be solved on my end somehow? And do I understand right that this is due to targeting SDK29? Or is there something else I could have made a mistake about while installing the Renpy? Like installing SDK through Renpy itself after download, for example.

Unfortunately I still have to target 29, anything newer is too restrictive. Although I haven't looked at the core mechanics for a while I doubt anything will change in Google's storage.
Android 16 will likely be more of the same.

Seems like I was wrong, it's not about android version because the person with android 12 got the same message, while the other with 15 didn't. It's something about specific android firmwares. For now, error was only on Xiaomi phones, so it breaks my theory about SDK target version.

Play Protect is updated independent of Android version and it's more to do with the age of SDK29
Play Protect pretty much follows similar rules as Google play store apps. For more info

I believe if we adhere to the new standards, then we lose the ability to write to the external directories. They got really super restrictive about what can access files outside the app's local storage.

Can you get some old, please?
I need more of the 745, 7.4.11, 744, and 746.
But if you have any extras and can send them, I would be very grateful.

 

[Derek Lamperouge]

I have a doubt in 7.4.11, although I read the instructions, there are three options for saving Single
'I will number the end of the masses to make it more noticeable.'

What is the RenPy version of the game you're trying to port?
Have you tried 7.5.0.242n? If this errors out 7.4.11 is unlikely to work as well. Look up the history of incompatible changes for RenPy, often there are switches you can use to revert behaviours.

It was 7.4.11, I managed to do it.

But will it work with 7.4.5/6?



What about this image?

I don't understand the three options. What are dual and single?

Dual would be in two locations? While single would be only one?

Single was only alternative saves folder, dual included the original android/data folder.
Dual is the behaviour going forwards.
7.5.0.242n is a nightly and much more backwards compatible than the 7.5 released.
I've also back ported a number of newer features into it and it contains fixes for Android that 7.4.11 never will.
