平台
RK3288 + Android 5.1
问题
内置应用失败, 编译LOG如下:
PRODUCT_COPY_FILES vendor/rockchip/common/nand/modules/arm/rk30xxnand_ko.ko.3.10.0:root/rk30xxnand_ko.ko.3.10.0 ignored. target Prebuilt: PrebuildApk (out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk) build/core/prebuilt_internal.mk:221: recipe for target 'out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk' failed make: *** [out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk] Error 1
Android.mk内容如下.
############################################################################### LOCAL_PATH := $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE := PrebuildApk LOCAL_MODULE_CLASS := APPS LOCAL_MODULE_TAGS := optional LOCAL_BUILT_MODULE_STEM := package.apk LOCAL_MODULE_SUFFIX := $(COMMON_ANDROID_PACKAGE_SUFFIX) LOCAL_CERTIFICATE := PRESIGNED LOCAL_SRC_FILES := $(LOCAL_MODULE).apk LOCAL_OVERRIDES_PACKAGES := Launcher3 LOCAL_PREBUILT_JNI_LIBS := \ lib/armeabi-v7a/libconceal.so \ lib/armeabi-v7a/libmp3lame.so \ lib/armeabi-v7a/libserial_port.so include $(BUILD_PREBUILT)
若LOCAL_CERTIFICATE := PRESIGNED
改为LOCAL_CERTIFICATE := platform
则编译正常.
分析

上面的代码, 没做很复杂的工作, 除了COPY, 就是COPY…
从报错的LOG来看, 是找不到 out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk
对应目录下当前的文件:
ls out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/ package.apk.aligned package.apk.unaligned
package.apk文件的产生与$(align-package) 有关:
|-- build/core/definitions.mk
# Align STORED entries of a package on 4-byte boundaries # to make them easier to mmap. # define align-package $(hide) mv $@ $@.unaligned $(hide) $(ZIPALIGN) -f 4 $@.unaligned $@.aligned $(hide) mv $@.aligned $@ endef
这段代码执行了脚本
package.apk => package.apk.unaligned
zipalign -f 4 package.apk.unaligned => package.apk.aligned
package.apk.aligned => package.apk
zipalign相关: APK优化工具zipalign的详细介绍和使用
在$(hide) $(ZIPALIGN) -f 4 $@.unaligned $@.aligned 后打上LOG:
$(hide) echo “zipalign finish”
发现并无LOG输出.
由此可推出, 在执行zipalign的过程出错了, 导致后面没有完成package.apk.aligned 到 package.apk的文件移动动作.
Zip alignment utility Copyright (C) 2009 The Android Open Source Project Usage: zipalign [-f] [-v] [-z] <align> infile.zip outfile.zip zipalign -c [-v] <align> infile.zip <align>: alignment in bytes, e.g. '4' provides 32-bit alignment -c: check alignment only (does not modify file) -f: overwrite existing outfile.zip -v: verbose output -z: recompress using Zopfli
添加 -c 试试:

Verification FAILED, zipalign执行失败, 但文件生成了, 而align-package也执行中断, 导致packae.apk不存在.
根据Makefile命令中的@和-符号中说明, 尝试加上 - (忽略执行结果)试试:
- $(ZIPALIGN) -v -f 4 $@.unaligned $@.aligned
hide := @, 在definitions.mk中有定义
build/core/prebuilt_internal.mk:218: recipe for target 'out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk' failed make: [out/target/product/rk3288/obj/APPS/PrebuildApk_intermediates/package.apk] Error 1 (ignored) Copy: out/target/product/rk3288/system/app/PrebuildApk/lib/arm/libconceal.so Copy: out/target/product/rk3288/system/app/PrebuildApk/lib/arm/libmp3lame.so Copy: out/target/product/rk3288/system/app/PrebuildApk/lib/arm/libserial_port.so Install: out/target/product/rk3288/system/app/PrebuildApk/PrebuildApk.apk
编译通过.
