解决方案

添加声明 android:sharedUserId="android.uid.system"

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="io.flutter.demo.gallery"
    android:sharedUserId="android.uid.system">

    <!-- The INTERNET permission is required for development. Specifically,
         flutter needs it to communicate with the running application
         to allow setting breakpoints, to provide hot reload, etc.
    -->
    <uses-permission android:name="android.permission.INTERNET"/>

    <!-- 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. -->
    <application android:name="io.flutter.app.FlutterApplication" android:label="Gallery" android:icon="@mipmap/ic_launcher">
        <activity android:name=".MainActivity"
                  android:launchMode="singleTop"
                  android:theme="@android:style/Theme.Light.NoTitleBar"
                  android:configChanges="orientation|keyboardHidden|keyboard|screenSize|locale|layoutDirection|fontScale|screenLayout|density"
                  android:hardwareAccelerated="true"
                  android:windowSoftInputMode="adjustResize">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>
                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>
</manifest>
