最近修改Android接口,报了一个VNDK的错误
我总结了如下几种方式:
1、直接关闭(不推荐):
在BoardConfig.mk中加入如下两行,可以在编译的时候不去check VNDK,关掉这个可能会导致XTS某些测项跑不过,一般code review也不会给过...
BOARD_VNDK_VERSION :=
BOARD_VNDK_RUNTIME_DISABLE := true
2、粗暴法:
删除如下目录的这些文件
/prebuilts/abi-dumps/vndk
./28/32/arm_armv7-a-neon/source-based/libion.so.lsdump.gz
./28/32/x86/source-based/libion.so.lsdump.gz
./28/64/arm64_armv8-a/source-based/libion.so.lsdump.gz
./28/64/arm_armv8-a/source-based/libion.so.lsdump.gz
./28/64/x86/source-based/libion.so.lsdump.gz
./28/64/x86_64/source-based/libion.so.lsdump.gz
./28/64/x86_x86_64/source-based/libion.so.lsdump.gz
我最终在本地的解法就是进入到/prebuilts/abi-dumps/vndk,搜索libmedia_omx, 将搜索到的libmedia_omx.so.lsdump*全部删除。并重新编译,结果就build pass了。这样也不太好,如果你上代码到服务器,自己这样一搞可以编过,那别人就惨了...
3重新生成(推荐):
其实报错信息有让你去跑一个脚本,之前我也有试过,始终跑不过,找了很多资料,结果少了-products xxx // xxx为boardname,敲如下命令就build pass了,上code到服务器,完美~
development/vndk/tools/header-checker/utils/create_reference_dumps.py -l libmedia_omx -products xxx // xxx为boardname
下面举例说明:
在hardware/interfaces/audio下新增了接口
报了一个VNDK的错误,如下:
意思就是android.hardware.audio.common@5.0::types 的哈希值在hardware/interfaces/current.txt存在,需要更新修改后的哈希值
执行命令:sha256sum ./audio/common/5.0/types.hal ,这里修改那个*.hal文件,就执行 sha256sum xx/xx/xx/*.hal
下面是我新生成的哈希值,发现这个值和上面error的值一样,也许编译时已经计算出
现在将新的值替换到hardware/interfaces/current.txt中对应行

重新编译后如果还报错:
需要执行:
development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.audio.common@5.0 -products TARGET_PRODUCT
来生成新的android.hardware.audio.common@5.0
例:
development/vndk/tools/header-checker/utils/create_reference_dumps.py -l android.hardware.audio@4.0 -products full_k50v1_64_bsp
他会换原先的,重新编译后通过。
