【问题描述】：
在 build.gradle 文件中升级以下行后
classpath 'com.android.tools.build:gradle:3.2.1'
gradle-wrapper.properties 文件中的以下行
distributionUrl=https\://services.gradle.org/distributions/gradle-4.6-all.zip
我的应用程序的签名发布 apk 根本不工作。虽然当我在开发模式下运行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。确保您的捆绑包包装正确或 你正在运行一个打包服务器。 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。任何帮助表示赞赏。
