Difficulties so far are +libraries that need tweaks to work with the new version of ghc, and some +that use cabal in ways that break cross compilation. Haskell's network +library was the last and most challenging of those. + +At this point, I'm able to start trying to build git-annex for android. +Here's the first try! + +

Can't seem to find a directory I can write to on the +Asus Transformer, with a filesystem that supports the +x bit. Do you really +have to root Android just to run simple binaries? I'm crying inside. + +It seems that the blessed Android NDK way would involve making a Java app, +that pulls in a shared library that contains the native code. For haskell, +the library will need to contain a C shim that, probably, calls an entry +point to the Haskell runtime system. Once running, it can use the FFI to +communicate back to the Java side, probably. The good news is that CJ van +den Berg, who already saved my bacon once by developing ghc-android, tells +me he's hard at work on that very thing. + +---- + +In the meantime, downloaded the Android SDK. Have gotten it to build a +`.apk` package from just javascript code, and managed to do it without +using eclipse (thank god). Will need this later, but for now want to wash +my brain out with soap after using it.
