android - 将 gradle 构建工具版本升级到 3.2.1 后，React Native 签名的 apk 失败

Question

升级后在build.gradle文件中加入以下行

类路径 'com.android.tools.build:gradle:3.2.1'

gradle-wrapper.properties 文件中的下一行

distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip

我的应用程序的签名版本 apk 根本无法运行。虽然当我在开发模式下运行应用程序时一切正常。

下面是我在 android studio logcat 中遇到的错误 -

2018-11-23 17:49:24.552 3506-3570/? E/AndroidRuntime: FATAL EXCEPTION: Thread-2 Process: com.simplydatanow.driverapp, PID: 3506 java.lang.RuntimeException: Unable to load script from assets 'index.android.bundle'.

这是已签名的发布 apk，因此 index.android.bundle 应该已经存在于 apk 中。但不知何故，它无法找到它。感谢您的帮助。

Answer 1

在build.gradle(Module:app)中修改版本号和版本名

转到 Build-->Generate Signed Bundle or Apk--> 选择 APK--> 单击“Next”--> 输入 keystore 凭据，或者如果你没有创建它--> 检查 V1 和 V2在签名版本中 --> 单击完成以生成签名的 APK。

将此 APK 上传到 playstore
