为什么我的Android Studio在安装（运行）后没有自动启动应用程序

Question

我通过单击android studio上的绿色箭头来构建和运行项目，我的应用程序应该会自动启动，但它只是安装了，什么也没发生。

我尝试重新安装android studio并创建一个新项目，但仍未解决。

这是我的“运行/调试”配置（仅为默认设置）。

这是android清单

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
    <activity android:name=".MainActivity">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>

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

我发现如下错误消息，为什么它断开连接？

Answer 1

它是由Chrome扩展程序-VideoStream引起的，它使用与adb相同的端口5556。只需终止或卸载它即可正常工作。
