一上来按照之前经验增加 wallpaper.te 文件，编译直接报错

错误一

ermediates/built_28.0_plat_sepolicy -o out/target/product/qssi/obj/FAKE/treble_sepolicy_tests_28.0_intermediates/built_28.0_plat_sepolicy -f /dev/null )"

和文件格式之类的有关系

在 file_contexts 中发现了一个例子 extra_free_kbytes.sh 看着靠谱，就直接复用它来

grep extra_free_kbytes_exec ./system/sepolicy/ -nir
./system/sepolicy/private/file_contexts:233:/system/bin/extra_free_kbytes.sh u:object_r:extra_free_kbytes_exec:s0
./system/sepolicy/private/compat/31.0/31.0.ignore.cil:19: extra_free_kbytes_exec
./system/sepolicy/private/compat/32.0/32.0.ignore.cil:29: extra_free_kbytes_exec
./system/sepolicy/public/extra_free_kbytes.te:3:type extra_free_kbytes_exec, system_file_type, exec_type, file_type;
./system/sepolicy/prebuilts/api/33.0/private/file_contexts:233:/system/bin/extra_free_kbytes.sh u:object_r:extra_free_kbytes_exec:s0
./system/sepolicy/prebuilts/api/33.0/private/compat/31.0/31.0.ignore.cil:19: extra_free_kbytes_exec
./system/sepolicy/prebuilts/api/33.0/private/compat/32.0/32.0.ignore.cil:29: extra_free_kbytes_exec
./system/sepolicy/prebuilts/api/33.0/public/extra_free_kbytes.te:3:type extra_free_kbytes_exec, system_file_type, exec_type, file_type;

错误二

解决办法在 31.0.ignore.cil 和 32.0.ignore.cil 中增加 wallpaper wallpaper_exec

最坑就是这个错误，一直查不到原因，隔了两天看了错误二中有 See examples of how to fix this 网址提示，去看了看，发现了一个文件 file_contexts_asan

把 /oem/bin/wallpaper.sh u:object_r:wallpaper_exec:s0 从 file_contexts 移动到 file_contexts_asan 中，编译错误解决。

system/core/rootdir/init.rc

on property:persist.test.wallpaper=1
    start  setwallpaper
