android - 更新应用程序崩溃 RealMigrationNeededException 但尚未修改 RealmObjects
问题描述
我最近发布了我的应用程序的新版本，更新到它后，由于“io.realm.exceptions.RealmMigrationNeededException：由于以下错误需要迁移”，应用程序立即崩溃
我的目标是更新应用程序，运行领域迁移而不会崩溃。
应用程序因 io.realm.exceptions.RealmMigrationNeededException 崩溃：由于以下错误需要迁移：
Property 'HistoryLogModel.bytes' has been made optional. (unmodified for this release)
Property 'StatusDataModel.data' has been made optional. (unmodified for this release)
Property 'TelemetryLogModel.data' has been made optional. (unmodified for this release)
Property 'TelemetryLogModel.timeStamp' has been made optional. (modified for this release and migration is created)
除了 TelemetryLogModel.timeStamp 之外，其余这些属性都未针对此版本进行修改。
该应用程序的原始版本具有io.realm:realm-gradle-plugin:7.0.2
最新版本有io.realm:realm-gradle-plugin:7.0.8
查看更新日志，这两个版本之间没有重大更改。
这是堆栈跟踪：
