I am building custom image.I going through android source, i want to get rid off bottom softkey button bar in android, Can some one please direct me to source file to change ?
To enable / disable them, as far as I know you simply have to edit the build.prop:
qemu.hw.mainkeys=0 (show on screen buttons)
qemu.hw.mainkeys=1 (disable on screen buttons)
If the line does not exist in your build.prop, add it at the bottom.
