根因分析
应用数据目录保留了之前安装的陈旧 UID，导致在卸载后未清除数据的情况下重新安装时 UID 不匹配。
English
App data directory retains a stale UID from a previous installation, causing a mismatch when reinstalling after uninstalling without clearing data.
官方文档
https://developer.android.com/studio/command-line/adb#installingapk解决方案
-
Uninstall the app completely with adb uninstall com.example.app, then reinstall via adb install path/to/app.apk. This removes the stale data directory.
-
On a rooted device, run adb shell and execute: su -c 'rm -rf /data/data/com.example.app' to force-delete the directory, then reinstall.
-
If using Android Studio, go to Build > Clean Project, then Run > 'Uninstall All' from the device dropdown, then rebuild and deploy.
无效尝试
常见但无效的做法:
-
Reinstall the app without clearing data first via adb install -r
95% 失败
The -r flag preserves app data, including the stale UID, so the mismatch persists.
-
Manually delete the package directory using adb shell rm -rf /data/data/com.example.app
80% 失败
On production devices without root, the shell lacks permissions to delete system data directories.
-
Change the package name in the manifest to avoid the conflict
90% 失败
This requires code changes and doesn't fix the root cause, leading to a different app identity.
