Question

升级build.gradle文件中的以下行

classpath 'com.android.tools.build:gradle:3.2.1'

和gradle-wrapper.properties文件中的行下面

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

我的应用程序的签名发行版APK根本不起作用。虽然当我在开发模式下运行该应用程序时，一切正常。

以下是我在android studio logcat中遇到的错误-

2018-11-23 17：49：24.552 3506-3570 /？ E / AndroidRuntime：致命异常：线程2 进程：com.simplydatanow.driverapp，PID：3506 java.lang.RuntimeException：无法从资产“ index.android.bundle”加载脚本。确保捆绑包包装正确，或您正在运行打包服务器。在com.facebook.react.bridge.CatalystInstanceImpl.jniLoadScriptFromAssets（本机方法）在com.facebook.react.bridge.CatalystInstanceImpl.loadScriptFromAssets（CatalystInstanceImpl.java:216）在com.facebook.react.bridge.JSBundleLoader $ 1.loadScript（JSBundleLoader.java:33）在com.facebook.react.bridge.CatalystInstanceImpl.runJSBundle（CatalystInstanceImpl.java:234）在com.facebook.react.ReactInstanceManager.createReactContext（ReactInstanceManager.java:1137）在com.facebook.react.ReactInstanceManager.access $ 900（ReactInstanceManager.java:113）在com.facebook.react.ReactInstanceManager $ 5.run（ReactInstanceManager.java:944）在java.lang.Thread.run（Thread.java:764）

这是签名的发行版APK，因此index.android.bundle应该已经存在于APK中。但是以某种方式无法找到它。任何帮助表示赞赏。

更改build.gradle（Module：app）中的版本代码和版本名称

转到Build->生成签名包或Apk->选择APK->单击'Next'->输入密钥库凭据或如果您没有创建它->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上载到Playstore

将gradle构建工具版本升级到3.2.1
