Question

我以前开发过一个应用，现在已经完成了更新。我在测试确定可以使用相同密钥和相同applicationId构建的APK时，程序包失败。

确保使用相同的applicationId和相同的密钥进行构建。
通过Google搜索解决方案。
降级构建工具/ gradle插件
升级到最新版本的构建工具/ gradle插件

这是我的设置：

builde.gradle：

    apply plugin: 'com.android.application'
    android {
        compileSdkVersion 28
        buildToolsVersion "28.0.3"

            project.ext.set("archivesBaseName", "1.0.7");
            // Make sure this is consistent with the redirect URI used in res/raw/auth_config.json,
            // or specify additional redirect URIs in AndroidManifest.xml
            manifestPlaceholders = [
                    'appAuthRedirectScheme': 'com.myapp.app'
            ]
        }
        signingConfigs {

无法安装新的APK，并显示错误消息：

奇怪的是这一行：

    06-20 13:36:55.168 1454-1548/? W/PackageManager: Package com.myapp.app shared user changed from com.myapp to <nothing>; replacing with new

请帮助，我很绝望。

应用程序更新失败，并显示错误消息：com.android.server.pm.PackageManagerException：scanPackageLI
