Thanks fadden for such a nice explaination. There was "-fno-short-enums" missing in my linux-arm.mk, while merging this file I did some mistake. Now it is working fine.
So simple steps to compile with armv6 are sync with latest android git and modified linux-arm.mk file as mentioned in my previous mail. Use the corresponding It will work fine. Now I am starting compilation for armv7, these are my changes ifeq ($(TARGET_ARCH_VERSION),armv7) ARCH_ARM_HAVE_THUMB_SUPPORT := true ARCH_ARM_HAVE_THUMB_INTERWORKING := true ARCH_ARM_HAVE_64BIT_DATA := true ARCH_ARM_HAVE_HALFWORD_MULTIPLY := true ARCH_ARM_HAVE_CLZ := true ARCH_ARM_HAVE_FFS := true arch_version_cflags := -march=armv7-a -D__ARM_ARCH_7__ I am getting this error: Copying: out/target/common/obj/APPS/SdkSetup_intermediates/classes.jar target Dex: SdkSetup target Package: SdkSetup (out/target/product/generic/obj/APPS/SdkSetup_intermediates/package.apk) target R.java/Manifest.java: SettingsProvider (out/target/common/obj/APPS/SettingsProvider_intermediates/src/R.stamp) target Java: SettingsProvider (out/target/common/obj/APPS/SettingsProvider_intermediates/classes) Note: frameworks/base/packages/SettingsProvider/src/com/android/providers/settings/DatabaseHelper.java uses or overrides a deprecated API.
