有人遇到过类似的问题吗?

Has anyone faced a similar problem?

谢谢.

推荐答案

在发布apk之前，我遇到了类似的问题，但我无法安装它，如果

I had a similar issue before while releasing apk, i was not able to install it, that was happening if the signature v2 is checked.

不幸的是，我不确定它为什么会导致此类问题！无论如何，如果您选中了v2，请尝试取消选中它，仅使用v1(罐子签名).

Unfortunately, I am not really sure why it causes such problems! anyway if you checked v2 try to uncheck it and use only v1 (the jar signature).

还要感谢 @codeMagic 为我们提供了

Also thanks to @codeMagic for providing us with this STO thread about differences between both types.
