Question

当我在模拟器上运行我的应用程序“RUN”时，它可以工作。但是当我手动安装 APK 时，我收到一条错误消息“未安装应用程序”，请问有什么想法吗？

Answer 1

禁用 minifyEnable。然后生成构建

 buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }

不工作我的 android studio 4.1.3 flutter 2.0.3

模拟器或物理设备上的“应用程序未安装”android？
