错误一

问题：没有指定keystore或指定路径不对

产生原因：

没有指定的Keystore，或者更换本地Keystore文件的位置导致。

解决办法：

找到有效的Keystore，在下图指定位置重新指定，并输入正确密码!

没有指定Keystore，报错原文：

UnityException: Can not sign the application Unable to sign the application; please provide passwords!

指定位置错误，报错原文

错误二

问题：无法合并AndroidMainFest。

产生原因：

导入了两个冲突的jar包，里面自定义的AndroidMainFest不能自动合并导致 下文中的【@android:authorities="com.czhenya.test.fileProvider" ----- @android:authorities="com.czy.test.fileProvider"】

解决办法：

找到对应的jar包，将两者统一。我这边是将其他工程使用的jar包误添加到此工程，所以直接删除，就解决问题了。若不确定是否还有其他用处，建议剪切到其他文件下进行备份并再次尝试打包。

产生原因：

AndroidSDK工具损坏或者版本过低

解决办法：

检测AndroidSDK配置或者升级AndroidSDK工具
