I have been asked to evaluate the Android platform for our product and I am looking at various options, I am only just scratching the surface just now and the one thing that is bothering me is that I cannot see how to compile code as straight ARM code (no Thumb), I know that Thumb runs slower and we will need the performance in key sections of our code.

I think it should just be setting the -march flag in the LOCAL_CFLAGS of the Android.mk file, but I cannot get that to work…

Can anyone help?

    Specifying the following flag for a module in Android.mk will compile straight ARM code.

    LOCAL_ARM_MODE := arm

    Enabling optimization may also help:

    LOCAL_CFLAGS := -O3
