Android Studio：无法找到 apk

Question

我正在尝试创建一个未签名的 apk，我可以在内部共享它以进行测试。在 Android Studio 上，我执行了以下操作：

1. 单击构建 -> 清理项目
2. 构建 -> 制作项目

构建成功并显示以下消息：

但是，我找不到 apk。我尝试查看项目的 app/outputs 目录，但该目录只有一个名为 logs/ 的文件夹，没有其他文件夹。任何建议都会有所帮助。

Answer 1

make 项目不会生成未签名的 apk。我犯了同样的错误你可以做的是使用 gradle 构建未签名的 apk。只需按照以下步骤操作（您可以比我输入这些步骤更快地完成）：

1. 在 运行 按钮的左侧，您应该会看到一个下拉列表，上面写着 "app"，左侧有一个 android 徽标。点击它。
2. 点击"Edit Configurations"
3. 单击左上角的绿色加号按钮 select "Gradle"
4. 在显示名称的地方，输入您想要的任何内容，其余的留空。我将我的设置为 "Assemble"
5. 在显示 "Before launch: Gradle task" 的下方单击绿色加号，然后 select "Run Gradle Task"
6. 在它说 "tasks" 的地方输入 "assemble"
7. 按OK再OK保存
8. 按 运行 按钮。 apk 将出现在 YourProjectFolderName>app>build>outputs>apk

要将 运行 按钮改回 运行 通过 adb 连接您的应用，只需再次单击第 1 步中的下拉按钮，然后 select "app"

另请注意，您不能在物理设备上安装未签名的 APK。无论您是通过电子邮件发送 apk、通过 USB 将其复制到 phone 存储，还是任何其他方法，它都不会让您安装它。您需要创建一个签名的 apk（非常简单）或将每个测试设备连接到您的计算机并通过 adb 安装。
