【问题描述】：

我正在制作一个项目，其中当用户单击按钮时，计时器将启动，并且在用户设置时间后，我会在我的颤振项目中使用 just_audio: ^0.6.15+1 播放声音，但这会导致以下许多问题是错误东西。

这是我的代码

var t = DateFormat.Hms().parse(time);
var rT = DateFormat.Hms().parse(remTime);
var co = t.isAfter(rT);

if (co) {
  player.setUrl('$soundUrl');
  player.setVolume(1);
  player.play();
  player.setLoopMode(LoopMode.one);
}

这是我的颤振医生-v

【问题讨论】：

您是否在 AndroidManifest 中添加了 android:usesCleartextTraffic="true"？
@KamrulHasanJony 不知道如何以及在哪里添加这个给我详细信息

标签： android flutter just-audio flutter2.0

【解决方案1】：

首先转到您的 AndroidManifest.xml。它可以在 /android/app/src/main 中找到。

然后在<application标签下添加android:usesCleartextTraffic="true"。

您的 AndroidManifest.xml 应如下所示

<application
        android:name="io.flutter.app.FlutterApplication"
        android:label="shafa_doctor"
        android:requestLegacyExternalStorage="true"
        android:usesCleartextTraffic="true" //just add this line only
        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">
