我的 Flutter 应用正在运行。 我将我的独立应用程序连接到 Firebase 我点击了这个链接: https://firebase.google.com/docs/flutter/setup?platform=android#add-flutterfire-plugins
在我搞砸我的安装和应用程序之前。 希望有人能够帮助我。
我正在使用运行 Android Studio、模拟器和 VS Code 的 Macbook。 谢谢你的时间! 罗伯特
【问题讨论】:
【参考方案1】:这是一个 multiDex 问题。正如您在堆栈跟踪中看到的那样Learn how to resolve this issue at https://developer.android.com/tools/building/multidex.html
在你的 android/app/build.gradle 的 defaultConfig 部分添加以下内容
multiDexEnabled true
并在依赖项下添加以下内容
compile 'com.android.support:multidex:1.0.3'
这将启用多索引支持。

【讨论】:
【参考方案2】:首先,您提出的建议是有效的!
但是是否可以更改文件 android/app/build.gradle 中的设置
defaultConfig
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.flutter_course"
minSdkVersion 16
targetSdkVersion 28
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
multiDexEnabled true
并将 minSdkVersion 16 更改为 21? 我在哪里可以找到最新版本的 minSdkVersion,以便保持最新?
感谢您的帮助!
