Android 13 内置可卸载的搜狗输入法

环境

系统：Android 13
芯片厂商：展锐

需求

默认只有英文输入法，没有中文，需要中文输入法，且可以卸载的。
实测为搜狗输入法，百度等其它输入法也同样适用。

实现

在SDK目录中创建packages/apps/SogouIME
从网上下载搜狗的apk重命名为SogouIME.apk放到SogouIME文件夹中。

创建Android.mk
注意有2个关键行
LOCAL_ENFORCE_USES_LIBRARIES := false　不加这个在安卓13中会编译不过
LOCAL_MODULE_PATH := $(TARGET_OUT)/vital-app　这行代码安装到/system/vital-app中，实现展锐的内置APP可卸载（恢复出厂可恢复）
整个mk内容如下

去掉LatinIME英文输入法，加上SogouIME

设置默认输入法
如果要改成百度输入法，可以把里面的默认百度输入法的2行配置注释去掉,把搜狗的删除就行．
