State of the Android port (1.5-2.1)

This problem will hopefully become less of an issue as Android matures, making Google more reluctant to change to much every version.

Please devs take Android as a more relevant priority, its the mobile platform that grows more quickly now.

It does run on android, but only on 1.5 and 1.6

Nope, currently running 2.2...everything is the same and all applications are functioning as normal, only thing missing is the SD application move...gotta wait for devs to enable it in their apps.

Just so everyone knows where I'm up to:

- I have rewritten all the audio and asset-reading code to avoid private Android APIs and instead call into supported Java routines.
- I have rewritten the graphics to avoid private Android 2D stuff and instead use (supported) OpenGLES.
- the port still uses my custom arm-android-eabi toolchain (not off-the-shelf NDK) since when I tried the NDK I hit some toolchain bugs. I'll tackle this one later.

So in theory, this should work properly on all Android versions 1.5 and newer (on arm CPUs). It will unfortunately use more memory+cpu than previous versions, but I haven't noticed any problems on my slower devices (Archos5 (software GL) and G1).

Fwiw I flip-flopped back and forth between GLES and other 2D approaches several times since neither was as efficient as the direct Surface access that I use currently. I think GL is the right choice long-term, since it should only get faster, while the 2D stuff will likely fall farther behind.

Remaining showstopper bugs:
- There are a few cases where portions of the screen don't get updated correctly - I need to double check my dirty rectangle tracking code.
- It works on all my other devices/emulators, but on my G1 I only get a black screen :( Probably something "special" about its GL implementation.
- There is some change in Android 2.0+ dynamic linker that completely breaks symbol resolution when loading plugins.

The last one looks the same as what hit some cyanogenmod versions too. I'm building an Android2.0 system image with extra linker debugging enabled so I can single-step through the linker and see what's going on. Fun.

Can't wait to try scummvm on the nexus!
Thanks for all your awesome work!

Likewise! I have two very long flights coming up in a week so if some testing is required I would REALLY love to help.

HTC Hero running VillianSense 6.2.0

I was playing Monkey Island on my Hero 1.5 before Rooting and I have to say it was amazing, stable and fast so please keep up the good work!

There are many of us who want to try ScummVM on our Nexus

Ah, if there just were more of you who don't just want to try it on the Nexus, but who also had the ability to help out with making this possible...

Well, I have a moto droid (2.1), but my coding skills are probably not up to par with you guys. I'm willing to do some testing if you guys need help in that regard though!

<<< I wanted to go into coding but ended up in Marketing

for shame I was not smart enough!

my first attempt to compile and run scummvm for Android (all version)
compiled original sources without any changes
temporary only with one engine scumm
tested on my Samsung i5700 Spica (Android 2.1)
