【问题描述】：

您好，我在 Play 商店中有应用程序。我更新了应用程序和颤振 2.0，但是当我在 Playstore 中下载应用程序时，互联网连接不起作用。我建立了发布模式并发送正常的电话互联网连接，但如果有人想要下载应用程序在 Playstore 连接不工作我不明白问题出在哪里。

这是我的主要 androidmanifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.agronet_seracilik">
         <uses-permission android:name="android.permission.INTERNET" />
         <uses-permission android:name="android.permission.CAMERA" />   
         <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />  
    <application
        android:name="io.flutter.app.FlutterApplication"
        android:label="Agronet Seracılık A.Ş"
        android:icon="@mipmap/ic_launcher">``
        <activity
            android:name=".MainActivity"
            android:launchMode="singleTop"
            android:theme="@style/LaunchTheme"
            android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
            android:hardwareAccelerated="true"
            android:windowSoftInputMode="adjustResize">
            <!-- Specifies an Android theme to apply to this Activity as soon as
                 the Android process has started. This theme is visible to the user
                 while the Flutter UI initializes. After that, this theme continues
                 to determine the Window background behind the Flutter UI. -->
            <meta-data
              android:name="io.flutter.embedding.android.NormalTheme"
              android:resource="@style/NormalTheme"
              />
            <!-- Displays an Android View that continues showing the launch screen
                 Drawable until Flutter paints its first frame, then this splash
                 screen fades out. A splash screen is useful to avoid any visual
                 gap between the end of Android's launch screen and the painting of
                 Flutter's first frame. -->
            <meta-data
              android:name="io.flutter.embedding.android.SplashScreenDrawable"
              android:resource="@drawable/launch_background"
              />
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
        <!-- Don't delete the meta-data below.
             This is used by the Flutter tool to generate GeneratedPluginRegistrant.java -->
        <meta-data
            android:name="flutterEmbedding"
            android:value="2" />
    </application>
    
</manifest>

【问题讨论】：

你试过了吗：***.com/a/65578828/1318946

现在可以使用了，谢谢。

【参考方案1】：

您需要在清单中授予应用程序权限

<application
    android:name="io.flutter.app.FlutterApplication"
    android:label="Agronet Seracılık A.Ş"
    android:icon="@mipmap/ic_launcher"
    android:usesCleartextTraffic="true"> --> Add this line to send http request after flutter 2.0
