android 系统如何添加多语言支持

之前在项目中遇到了这样一个问题，因为项目要适配多语言，但是奇怪的是，在android 的自带的setting=》language列表中和开机导航页中有好几种语言就是显示不出来。

解决：

framework/base/core/res/res/下添加如下：

增加对应语言的的文件夹（eg：中国台湾），并且该文件夹中有以下两个文件（目录结构如下）：在这里插入图片描述

其中，第一个文件：donottranslate-maps.xml 内容如下（这个文件好像也可以不要）：

<?xml version="1.0" encoding="utf-8"?>

<resources>

    <!-- Do not translate. -->
    <integer-array name="maps_starting_lat_lng">
        <item>40083518</item>（这两个是对应国家的经纬度）
        <item>4734369</item>
    </integer-array>
    <!-- Do not translate. -->
    <integer-array name="maps_starting_zoom">
        <item>4</item>
    </integer-array>

</resources>

strings.xml
此文件下为android系统中主要的翻译，具体可以根据英语文件夹下的翻译。一版低版本上都有。可以直接拷过来

另外这还不算完，前面只是配置了android系统支持此语言，但是要是想要在开机导航和settings中显示对应的国家语言，还要在以下文件中配置。
在device下的oem.mk文件中（名字不一定为oem.mk,一版为厂商名字或者特定的名字.mk）

PRODUCT_BOOT_JARS += com.mediatek.mtkaudiopatchmanager 

PRODUCT_NAME := globe_na
PRODUCT_BRAND := globe_ATV
PRODUCT_DEVICE := globe_na
PRODUCT_MODEL := globe
#sky wayhome modify for PRODUCT_MANUFACTURER netflix test, 2018.01.25
PRODUCT_MANUFACTURER := Skyworth
export TV_WORK_WITH_ALEXA_SUPPORT ?=true
# Put en_US first in the list, so make it default.
PRODUCT_LOCALES := en_US en_CA fr_CA es_ES ko_KR zh_CN zh_TW(***在此行配置对应的语言缩写***)
# inherit from the non-open-source part, if present
$(call inherit-product-if-exists, vendor/toshiba_globe/device-vendor.mk)

# Build WebView from source when using the internal source.
override PRODUCT_PREBUILT_WEBVIEWCHROMIUM := $(PRODUCT_USE_PREBUILT_GMS)

这样，就可以显示想要的国家语言了。
