我正在使用Appium在Android设备上编写自动化测试。我需要设置不同的语言，并使用语言和语言环境功能，并将它们设置如下：
capabilities["language"] = "sv"
capabilities["locale"] = "SE"
它适用于Android Emulators（v 6.0 / API 23，v7.1.1 / API 25）。它适用于OS 7.0（API 24）及更高版本的不同实际设备。它不适用于API 23及更低版本的真实设备。我总是收到一个错误：
selenium.common.exceptions.WebDriverException：消息：处理命令时发生未知的服务器端错误。原始错误：无法设置语言：sv和国家/地区：SE
我尝试了不同的组合，比如在sv_SE sv-SE等设置的语言环境，但没有任何帮助。

如何使用Appium在较低的API版本上更改设备语言？
它不支持每个official Appium docs的Real Devices
language（Sim / Emu-only）为模拟器/仿真器设置的语言。在Android上，仅适用于22级及以下的API级别
例如：fr
locale（仅限Sim / Emu）为模拟器/仿真器设置的区域设置。
例如：fr_CA
它可能已经开始用于运行OS 7+的一些真实设备，但这更像是谷歌的奖励，相当肯定它不适用于每一个。
https://github.com/appium/io.appium.settings怎么样？对不起，我没有尝试，但它似乎支持更改区域设置没有API级别限制。
