android - 无法打开dex文件，无法识别版本号

Question

我已将 apk 推送到电视盒上的 system/priv-app，但当我尝试卸载应用程序时收到此错误:

dex2oat : Failed to create oat file: /data/dalvik-cache/arm/system@priv-app@<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="1a597b746c7b694a7b79717b7d7f5374696e7b76767f685a597b746c7b694a7b79717b7d7f5374696e7b76767f68347b6a71" rel="noreferrer noopener nofollow">[email protected]</a>@classes.dex: Permission denied

我尝试清理 dalvik 缓存，但没有成功。这是什么意思？

Answer 1

037 版本的 dex 格式是在 N 时间范围内引入的。 Android 版本早于 N 的设备将无法读取它。
