我正在制作一条短信备份和恢复 Android 应用程序。
不幸的是，我的应用程序无法在小米手机上恢复短信，包括带有Android 6的Redmi 3s，带有Android 12的Redmi Note 11，但在其他手机中，它可以很好地执行短信备份和恢复操作。
我该如何解决这个错误？

此外，在我的 MainActivity 文件中，我已获取 Manifest.permission.READ_SMS 权限。
更新：我删除了手机上的所有短信，没有类似的id，不再显示错误Logcat，但错误仍然存在，短信无法恢复，仅在小米手机上。
我刚刚注意到重复 ID 的问题已得到解决。嗯，这个问题只存在于小米手机上。
尝试检查以下可能性。
如果问题仍然存在，请考虑在小米设备上进行短信备份和恢复的替代方法。小米的定制可能会与某些方法发生冲突。您可以探索使用小米官方备份和恢复 API（如果可用）等选项。
