| # BanUninstall | ||
|
|
||
| 一个禁止卸载和禁止清除用户数据的Xposed模块 | ||
|
|
||
| A Xposed Module that prevents apps be uninstall or apps' data be cleared | ||
|
|
||
| ### Compatibility | ||
| Android 5.0 - Android 14 | ||
|
|
||
| I have tested with my phone on Android 14, and it works well. I can't ensure it works on your phone. | ||
|
|
||
| **So before you use it, you must test it with an irrelevant app by yourself.** | ||
|
|
||
| **I am not responsible for any data loss if you test it using an important app.** |
