android - App Center - Android 版本在启动时崩溃

Question

通过 App Center 部署 React-Native 应用时出现问题 - 在本地执行 gradlew assembleRelease 时没有崩溃。
IOS build, deploy and running 构建成功。
在 Android 中 - 构建成功通过，但当我安装应用程序时它在启动时崩溃。

当我检查 logcat 时，我看到以下错误 - 该版本似乎是调试版本(提到了 metro)，但我不确定。

可能是什么问题？

Answer 1

终于解决了。这似乎是一个 react-native 0.63.3 问题，而不是 App Center 问题。

执行以下操作时:

gradlew clean
gradlew assembleRelease // or other variant

这个问题是Build成功了，但是apk里面没有创建index.android.bundle文件。

检查您是否可以:

1. unzip [APK_FILE] -d [directory] 
2. Go to assets directory and look for index.android.bundle file.

仅在再次运行之后:

gradlew assembleRelease // or other variant

我们得到apk里面的index.android.bundle文件

似乎存在任务顺序问题 - 已通过此 thread 解决

通过添加到 app/build.gradle:

// Fix for bundle not getting included in APK or AAB with android gradle plugin 4+
// Seems like there's a React-Native bug - task ordering issue and the assets get computed before the bundle is copied
// This forces the copy task to run before merge resources
// This should be fixed and removed starting with RN 0.63.4.
// Relevant thread: https://github.com/facebook/react-native/issues/29398#issuecomment-724350920
project.afterEvaluate {
  def isAndroidLibrary = plugins.hasPlugin("com.android.library")
  def variants = isAndroidLibrary ? android.libraryVariants : android.applicationVariants
  variants.all { def variant ->
    def targetName = variant.name.capitalize()
    def mergeResourcesTask = tasks.findByName("merge${targetName}Resources")
    def assetsCopyTask = tasks.findByName("copy${targetName}BundledJs")
    mergeResourcesTask.dependsOn(assetsCopyTask)
    logger.warn("Making task ${mergeResourcesTask} depend on ${assetsCopyTask}")
  }
}
