在构建apk时，在android apk中显示APP未安装错误

Question

我已经生成了一个签名的 apk 并提供给客户端。下次当我使用相同的签名 apk 构建 apk 时。安装时显示为未安装应用程序。有人请告诉我为什么会这样

请找到我的 gradle 代码。版本代码为 1，版本名称为 1.1 用于以前的构建

应用插件：'com.android.application' 安卓{

Answer 1

可能发生的原因有几个：

1. 以前的版本代码低于当前版本。尝试增加它或/并在设备上的应用信息屏幕中检查版本名称
2. 签名不匹配。小心他们的数据
3. 关闭谷歌播放保护。可能问题出在谷歌服务的某个地方
