生成 APK（已签名）升级 gradle 版本时出现问题

Problem when generating APK (signed) upgrading gradle version

提问人：Alejandro Casado Benito 提问时间：12/20/2021 最后编辑：Alejandro Casado Benito 更新时间：7/8/2022 访问量：2483

问：

我正在尝试将我的 gradle 版本更新到最新版本，一切正常，但是当我生成签名的 APK 时，应用程序停止工作（无法启动）。 目前我有： Android gradle 插件版本：4.1.2 Gradle 版本：6.5

我试过更新到： Android gradle 插件版本：4.2.0 Gradle 版本：7.0.2 这就是我有问题的地方，我生成了签名的APK，但应用程序无法正常工作。

我怀疑它是否与 Proguard 或 R8 有关，我不太了解这些文档，所以我尽量不运行它们以查看它是否来自那里的故障，但即使这样我也没有让它工作。

我构建类型：

buildTypes {
    release {
        minifyEnabled true
        shrinkResources true
        proguardFiles 'proguard-android.txt'
    }
}

你知道问题可能出在哪里吗？

您能否在logcat中找到并在此处发布您尝试启动应用程序时正在打印的错误？（按包名过滤 logcat 日志通常会有所帮助）

这是你的崩溃：。此行下方应该有一个完整的异常堆栈跟踪，请查看。正如你所看到的，有一个对 null 引用的方法的调用。你能在源代码中找出确切的行吗？如果是 - 请尝试添加一些日志以找出导致它的原因。12-24 11:23:11.978 23520 23520 E AndroidRuntime: java.lang.RuntimeException: Unable to create application com.spotbros.application.SpotbrosApplication: java.lang.NullPointerException: Attempt to invoke interface method 'boolean android.database.Cursor.moveToFirst()' on a null object referenceCursor.moveToFirst()

我仍在寻找光标错误，但我找不到它。但是我尝试更新附加组件和 gradle 版本，并且在更新附加组件时发生错误。因为如果我把 Android Gradle 插件版本：4.1.2 Gradle 版本：7.0.0.0 它可以正常工作。知道为什么会这样吗？

您必须为 'minifyEnabled' 设置 false，为 'shrinkResources' 设置 release

buildTypes {
release {
    minifyEnabled false
    shrinkResources false
    proguardFiles 'proguard-android.txt'
    }
}

感谢您的回复，我也试过了，但它也不起作用。我一直在尝试更新插件和 gradle 版本，但当您更新插件时失败。因为如果我把 Android gradle 插件版本：4.1.2 Gradle 版本：7.0.0 它可以工作

如果您在应用程序中使用数据库，可能是因为您在 ProGuard File for Database 中的设置，您应该在签署 APK 时检查数据库文件是否存在。
