从 Android v1 迁移到 V2

Question

大家好，我是 Flutter 的新手，我遇到了这个问题。

我的应用程序显然是 V2，但 Android 工作室仍然表示该应用程序必须迁移。

我执行了他们建议的步骤，但仍然得到相同的结果有人可以建议我做错了什么吗？这是我必须做的事情的链接： https://github.com/flutter/flutter/wiki/Upgrading-pre-1.12-Android-projects

这是我修改的。

AndroidManifest.xml

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.ipill">
    <!-- io.flutter.app.FlutterApplication is an android.app.Application that
         calls FlutterMain.startInitialization(this); in its onCreate method.
         In most cases you can leave this as-is, but you if you want to provide
         additional functionality it is fine to subclass or reimplement
         FlutterApplication and put your custom class here. -->

            <meta-data
                android:name="io.flutter.embedding.android.NormalTheme"

            <!-- Displays an Android View that continues showing the launch screen

                 gap between the end of Android's launch screen and the painting of
                 Flutter's first frame. -->
            <!-- Specify that the launch screen should continue being displayed -->
            <!-- until Flutter renders its first frame. -->

            <intent-filter>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>

        <!-- Don't delete the meta-data below.

        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
        <meta-data
            android:name="com.google.android.gms.wallet.api.enabled"
            android:value="true" />
        <meta-data
            android:name="com.google.android.geo.API_KEY"
            android:value=""/>
    </application>

</manifest>

文件 MainActivity.kt 包含以下内容

 package com.example.ipill

import io.flutter.embedding.android.FlutterActivity

class MainActivity: FlutterActivity() {

}

我还尝试使用 flutter install --ignore-deprecation 标志，但他们说它不起作用。

任何帮助，因为我迷路了，我真的需要让应用程序工作，我发现了一个类似的问题，我应用了他们的建议，但它不起作用。

这是我得到的日志

Answer 1

我能够通过设置来解决这个android:name问题

android:name="${applicationName}"在android/app/src/main/AndroidManifest.xml

显然，即使你已经升级到 V2 嵌入，Flutter 2.10 的检查也比以前的版本更严格。

Answer 2

在你的 main/xml 文件中，更改android:name为android:name="${applicationName}
