一、语言

1、修改路径：build/target/product/full_base.mk

-# Put en_US first in the list, so make it default.
-PRODUCT_LOCALES := en_US
+# Put zh_CN first in the list, so make it default.
+PRODUCT_LOCALES := zh_CN en_US

2、修改路径：build/target/product/languages_default.mk        //这里把zh_CN移到第一个即可

PRODUCT_LOCALES := \
        zh_CN \
        en_US \

二、时区

在RK平台，默认的代码中的时区是GMT

本人验证过，联网后时间不会跟着网络的时间走，必须得自己点一下对应的时区，时间才匹配。

以下是修改默认时区的patch

//cd frameworks/base/
//这里默认的时区，我修改的是上海
