Reduce Binary Size

[laurent mallet]

Hello,

I have 3 libraries in my project. The release size is about 5Mo with
default parameters in Android.mk.
After ndk-build, i use "arm-eabi-strip -s libs/armeabi" to reduce size
to 4Mo.
It is too big. So after some googling, i try some interesting flags:

LOCAL_CFLAGS := -ffunction-sections -fdata-sections ...
LOCAL_LDFLAGS := -Wl,-Map=moblox.map,--cref,--gc-section

With these flags, the size is 3Mo. It is working on Nexus One and G1.
But i'm not sure
that these flags are legal. Is there any recommandations for
authorized flags for NDK build ?


Thx,

Hi,

Are you using c++?

Maybe -fvisibility=hidden can help.

Thanks,
Anders

Hi,

You're my savior. The size of my library is now 1.5Mo with all these
flags. It is a bit painfull, but it rocks.

Thanks.
