你设置了 RELEASE_STORE_FILE="" 的路径吗？ - Faysal Ahmed

将path参数的值设为空白，然后发送。 - Cyph3rCod3r

是的 RELEASE_STORE_FILE="" - Keyur Patel

我需要设置哪个路径？ - Keyur Patel

这将是您的应用程序密钥库文件URL。 - Faysal Ahmed

Answer 1

您提供的密钥库路径是""。请检查gradle.properties文件，确保它包含RELEASE_STORE_FILE=""。将""替换为您的密钥库路径。如果您现在不需要，则只需删除这些行并进行检查。

- Faysal Ahmed

---

这个没有默认路径。在调试期间，您可以删除这些行。当您想要创建签名的APK时，您需要创建一个密钥库文件。当您拥有该文件后，添加那些行并设置密钥库文件的路径。 - Faysal Ahmed

没有第一个干净的Gradle签名APK，无法生成。 - Keyur Patel

我已经设置了密钥库路径，但仍然收到相同的错误。 - Khyati Chitroda

请问您能分享一下 Git 仓库的 URL 吗？ - Faysal Ahmed

RELEASE_STORE_FILE="D:\Demos\linphone-android-master\keystore.jks" 不是正确的设置方式。这个设置是可选的，你可以尝试将其删除，然后重新运行。 - Faysal Ahmed

Answer 2

如果你正在使用React Native和EXPO，运行以下命令：

npx expo prebuild --platform android --clean 

重新生成Android目录

- Leandro Ariel

Answer 3

不要尝试从Android Studio打开它。这是带有自动构建的C语言文件。请阅读readme。
