Android mtk 系统应用改为可卸载，恢复出厂可恢复

news 来源：原创 2025/6/14 7:18:30

ystem/app或者priv-app目录下的系统应用需要可卸载

vendor/mediatek/proprietary/frameworks/base/data/etc/pms_sysapp_removable_system_list.txt
在文件中添加需要可卸载应用的包名

 com.android.quicksearchboxcom.android.calendarcom.android.dreams.basiccom.android.musicfxcom.android.calculator2com.android.emailcom.android.exchange
+com.android.fmradio

将systemapp改为可卸载后打开报错，如：
