Support for Android

[lfuelling]

I'm not sure if GTA SA uses the same savegame format for Android as on PC. If yes, we could easily port the editor to Android. The TODOs below all depend on the first one. If Android uses another format or doesn't save locally at all (☁️) it might not be possible to port this.

Android does indeed use a similar savegame format than the PC version.

Steps to take:

• Evaluate the Android Savegame Format
  • Find out if the same blocks are used
  • Find out if the blocks of the android version and the pc version have the same stuff in them
  • Find out if some blocks are empty/unused in the Android version that are used on PC and vice-versa
• Refactor the Savegame handling logic to make it able to handle Android savefiles
  • Get the command line tool to extract blocks from an Android save
  • Get the command line tool to assemble a valid Android save
  • Implement the necessary stuff in libsavegame to make it able to read Android savegames
  • Implement the necessary stuff in libsavegame to make it able to save valid Android savegames

Upd8: What I found out so far:

• Android savegames also go from 1 to 8 with the same naming scheme. Additionally there are 9 and 10 savegames that are always "present" (on the file system) and seem to contain the two "cloud slots".
• Android savegames have a size of ~190500 bytes
  • The usual blocks used for the PC version don't work with this
  • Either the blocks are smaller or some are left out Some blocks are empty
• The savegame-extractor is able to load the savegame into the editor but it crashes as soon as it's loading the file.

Further updates, notes and task tracking will happen in:

• [WIP] Android Support #37
• [WIP] Android Docs docs#42

It's giving error "This file is not a GTA San Andreas PC save game" when I try to load save game from my Android device using the extractor

Yes, that's because this feature is still in development.
If you want to help please take a look at the links at the bottom of the issue description!

Hey, is this still in development? I'd love to help out with this in some way, if possible. I have a feeling with the release of the Vita port, there will be renewed interest in this tool working on Android Saves. I have a bit of game modding and coding experience, so I may be able to help you with some save files and research.

Hi @FloDoc, yes, this is still "in development" although to be honest I'm simply too dumb to properly analyze the differences of the android savegame.
I managed to extract the Blocks using the cli and snooped through with a Hex editor, but I was unable to identify the already documented values and stopped further analysis.

If you want to help, the best way to start might be taking a look at the docs and the cli which lets you extract a given savegame to block files that can in turn be inspected with any Hex editor.

Cool, will do! I've already found some interesting things like ammo and how that's different from PC. I'll keep you posted. Get Outlook for Android<https://aka.ms/ghei36>

Have you seen my GTASA binary template for the 010 Editor? It can parse almost everything in San Andreas save files of PC, PS2, OG Xbox and Android/iOS. 010 usually offers a generous trial period, if necessary. And if you don't have 010, you could probably pull all major differences between the various versions out of the constants lists and conditional statements in the structures. With 010, everything is all mapped out, and there's tons of enums and functions to help make the data easier to understand.
