android - react-native run-android build 在没有红屏的情况下启动时崩溃

Question

我正在尝试在 Android 上构建我的应用程序的调试版本。离线版本工作正常。 (使用 react-native bundle ...)。但当然，它不会触发地铁 bundler 。此外， bundler 正在监听构建，当在浏览器上调用 https://localhost:8081/index.bundle?platform=android 时，它开始 bundle 。我试过:

1. 删除 build 文件夹
2. 生成新的 debug.keystore
3. 运行 ./gradlew clean
4. watchman watch-del-all
5. rm -rf .gradle
6. rm -rf node_modules
7. rm -rf package-lock.json
8. npm i
9. 运行 npx react-native run-android

以及几乎所有类型的清洁和重置。但是还是没有机会。这是一个高度自定义的项目，我无法更新 react-native 版本或清理 android 文件夹。

这是我的 react-native info 结果:

这是用于调试的 build.gradle 设置:

buildTypes {
        debug {
            signingConfig signingConfigs.debug
            applicationIdSuffix ".demo"
            versionNameSuffix " - Dev"
            resValue "string", "app_name", "My App"
        }

我相信定制以某种方式进行了一些更改，构建版本实际上不是显示调试红屏并连接到开发服务器的调试版本。但是我找不到要更改的源。

我还在我的笔记本电脑上安装了一个 react-native init --version 0.61.5，它安装、运行并连接到 Metro 服务器就像一个魅力。因此，如果您有任何进一步深入检查配置和 android 文件夹的建议，我将不胜感激。我尝试了很多关于 StackOverflow 的问题以及关于 react-native、react-native-CLI 和 metro repos 的问题，但找不到我需要的任何高级指南。

Answer 1

在 StackOverflow 上发布问题的魔力奏效了，经过几次尝试后我找到了答案。显然，问题出在 MainApplication.java 中导入的 BuildConfig 文件。这会导致程序使用导入的构建配置而不是此文件中的调试配置:

@Override
    public boolean getUseDeveloperSupport() {
      return BuildConfig.DEBUG;
    }

因为库在其构建配置中使用生产配置，当我们导入它时，编译器会阻止调试功能。这就是它无法连接到地铁 bundler 的原因。

因此，如果您正在查看此问题并遇到同样的问题，请确保检查 MainApplication.java 并删除您找到的任何外部 BuildConfig，例如:

import com.facebook.react.BuildConfig;
import androidx.multidex.BuildConfig;

在我的例子中，第二个在代码中。执行此操作后，请确保删除离线包(如果有):

rm android/app/src/main/assets/index.android.bundle

并删除 android build 文件夹:

rm -rf android/app/build

或:

cd android && ./gradlew clean

现在您可以运行 react-native run-android，它有望成功构建、运行并连接到 bunder。
