android9.0 framewrok.jar push到system/framework不起作用，解决方式:
adb push out/target/product/xxx/system/framework/boot-framework.vdex /system/framework/
adb push out/target/product/xxx/system/framework/arm/boot-framework.art /system/framework/arm
adb push out/target/product/xxx/system/framework/arm/boot-framework.art.rel /system/framework/arm
adb push out/target/product/xxx/system/framework/arm/boot-framework.oat /system/framework/arm
有的小伙伴不起作用，然后把services.jar 一起push进去就可以了
adb push out/target/product/xxx/system/framework/services.jar /system/framework/
然后重启设备，打印出了framework的log
