Question

我正在尝试将Flutter添加到现有的Android应用中，但运行时崩溃了。我正在按照以下步骤操作： https://github.com/flutter/flutter/wiki/Add-Flutter-to-existing-apps。我知道这仍然处于测试阶段，并且在不久的将来可能会变得更好，但是我希望能够帮助其他人，或者我想错过一些简单的东西。

启动FlutterActivity的意图时，活动会启动，但会立即崩溃应用程序。开始活动看起来像这样：

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

这是我正在使用的颤动版本：

$ 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。这已被修改以保证安全性并使其简短，因此我可能会遗漏一些重要内容：

我已经能够使用新的Android项目，但我认为现有的Android项目可能会影响构建。

您可能需要查看Arnold Parge在Medium中的文章Embedding Flutter in existing Android project。

它详细解释了调整build.gradle，AndroidManifest.xml，MainActivity.java和其他android文件。

与现有应用程序混乱
