android - When exporting .Apk in the android manifest its does not install on other phones, when getting from Bin folder it does install?

Question

Basically I made an app and exported the .apk (from the Android Manifest exporting section) so I could try it on my dad's phone.

I tried to install it on my dad and sister's phone and it gave "application not installed" however if I get the .apk from the Bin folder it works fine. Am I doing something wrong?

If I want to install the app on another phone what would I use to get the .apk? Is getting the .apk from bin safe as it does not have certificate?

证书很可能有问题。尝试制作新的证书、密钥库和别名，然后再次生成 .apk。当您尝试安装此新版本时，请确保手机上没有以前的应用程序实例，否则签名不匹配将导致安装失败。

另外，他们的手机上是否已经安装了以前版本的应用程序？由于同时使用有符号和无符号，可能会出现签名不匹配（实际上 .apk 是签名的，但它是由系统自动完成的） .apks
