AOSP: Cannot pack presigned apk

I build my project in Android Studio and generate signed apk, then put my apk in Android Open Source Project to pack my app with system image.
I followed these steps to pack my app with system image.
My problem is this line in Android.mk:

LOCAL_CERTIFICATE := < desired key >

if I don't sign the apk and use

LOCAL_CERTIFICATE := platform

everything goes well and build is successful
but if I sign my apk and use

LOCAL_CERTIFICATE := PRESIGNED

my build fails with Error 1:

make: *** [out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk] Error 1

for verbos log I make project with make showcommands and this is where error happens:

mv out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.unaligned
out/host/linux-x86/bin/zipalign -f -p 4 out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.unaligned out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.aligned
make: *** [out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk] Error 1

so the problem is zipalign! build system should not use zipalign for signed apk, but why does it use?

My full Android.mk:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)
LOCAL_MODULE := MyApp
LOCAL_MODULE_TAGS := optional
LOCAL_CERTIFICATE := PRESIGNED
LOCAL_DEX_PREOPT := false
LOCAL_MODULE_PATH := $(TARGET_OUT)/preinstall
LOCAL_MODULE_CLASS := APPS
LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX)
LOCAL_SRC_FILES := my_app.apk
LOCAL_PRIVILEGED_MODULE = true
LOCAL_OVERRIDES_PACKAGES := Home Launcher2 Launcher3


include $(BUILD_PREBUILT)

mv out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.unaligned

out/host/linux-x86/bin/zipalign -f -p 4 out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.unaligned out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk.aligned

make: *** [out/target/product/helpera64-v2/obj/APPS/MyApp_intermediates/package.apk] Error 1

From the error log, the zipalign command executed failed, so the potential failed reason is that your apk with wrong align. Maybe you can follow the Android's zipalign document to ensure your apk with the correct align.

PS: I have encountered the similar problem because of presigned apk has wrong align so file.
