Android 8.1.0，
展锐平台。
过CTA认证，内置的触宝输入法会连接网络，且默认就获取到访问网络的权限，没有弹请求窗口访问用户，会导致过不了认证。

预置应用触宝输入法Go版连网未明示（开启后），流量耗费触宝输入法Go版连网未明示

对应方法：禁用触宝输入法。改用原生google输入法
常见输入法的包名和类名
百度：com.baidu.input/.ImeService
讯飞：com.iflytek.inputmethod/.FlyIME
腾讯：com.tencent.qqpinyin/.QQPYInputMethodService
谷歌：com.google.android.inputmethod.pinyin/.PinyinIME
搜狗：com.sohu.inputmethod.sogou/.SogouIME
触宝：com.cootek.smartinput5/.

设置默认输入法为原生输入法LatinIME

安卓8.1 用的平台SDK自触宝输入法，设备启动后会看到如下目录system/vital-app/TouchPalGlobal/
想删除掉，换成谷歌的。
SDK触宝目录./vendor/sprd/partner/TouchPal
搜索到启用触宝的编译配置项：
sprd/feature_configs/oversea/config.mk:18: TouchPalGlobal

删除其配置

查找SDK下触宝相关

删除触宝
rm vendor/sprd/partner/TouchPal/ -r

out目录下也有一些编译后的apk等文件，也一样删除掉。

也可以设置成谷歌中文输入法
