android - Flutter 与现有应用程序崩溃

Question

我正在尝试将 Flutter 添加到现有的 Android 应用程序中，但遇到了运行时崩溃。我正在执行以下步骤: https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps .我知道这仍处于测试阶段，在不久的将来可能会变得更好，但我提出这个是希望能帮助其他人，或者万一我错过了一些简单的事情。

当启动我的 FlutterActivity 的 Intent 时，该 Activity 已启动，但随后立即使应用程序崩溃。开始 Activity 看起来像这样:

ComponentName componentName = new ComponentName(getActivity(), "com.example.flutterpart.MainActivity");
Intent intent = new Intent().setComponent(componentName);
startActivity(intent);

这是我使用的 flutter 版本:

$ flutter --version
Flutter 0.4.4 • channel beta • https://github.com/flutter/flutter.git
Framework • revision f9bb4289e9 (4 weeks ago) • 2018-05-11 21:44:54 -0700
Engine • revision 06afdfe54e
Tools • Dart 2.0.0-dev.54.0.flutter-46ab040e58

这是崩溃日志。为了安全起见，为了简短起见，这已经被修改，所以我可能遗漏了一些重要的东西:

我已经能够在一个新的 Android 项目中使用它，但我认为我现有的 Android 项目中可能有一些东西影响了构建。

你可能想看看文章 Embedding Flutter in existing Android project在 Arnold Parge 的 Medium 中。

它详细解释了如何调整 build.gradle、AndroidManifest.xml、MainActivity.java 和其他 android 文件。
