Preface: I am using Flutter to develop an Android app.But I found that when I open the App and then switch to the background, and then reopen the App after a while, the App will be stuck on the startup page and cannot be opened normally.
This is my MainActivity:
class MainActivity: FlutterActivity() {
///There is Nothing.
}
This is my AndroidManifest.xml configuration：
<activity
android:name=".MainActivity"
android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode"
android:exported="true"
android:hardwareAccelerated="true"
android:launchMode="singleTop"
android:theme="@style/LaunchTheme"
android:windowSoftInputMode="adjustResize">
<meta-data
android:name="io.flutter.embedding.android.NormalTheme"
android:resource="@style/NormalTheme" />
<meta-data
android:name="io.flutter.app.android.SplashScreenUntilFirstFrame"
android:value="true" />
<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>
<meta-data
android:name="flutterEmbedding"
android:value="2" />
The launch_background content is:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="?android:colorBackground" />
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/ic_logo" />
</item>
</layer-list>
And,the main.dart code:
void main() async {
await onCreated();
runApp(const App());
}
class App extends StatelessWidget {
const App({super.key});
@override
Widget build(BuildContext context) {
return GetMaterialApp(
title: AppConfig.getAppName,
debugShowCheckedModeBanner: false,
locale: const Locale('zh', 'CN'),
fallbackLocale: const Locale('zh', 'CN'),
theme: ThemeData(
primaryColor: AppColors.primaryColor,
),
defaultTransition: Transition.rightToLeft,
getPages: AppRoutes.appRoutePages,
initialRoute: AppRoutes.getAppInitPage,
routingCallback: (value) {
AppRoutes.onAppRouteCallback(value);
},
builder: FlutterSmartDialog.init(),
navigatorObservers: [FlutterSmartDialog.observer],
localizationsDelegates: GlobalMaterialLocalizations.delegates,
supportedLocales: const [
Locale('zh', 'CN')
],
);
}
...
}
onCreated() content is:
Future onCreated() async {
logInfo("#startAppInit");
WidgetsFlutterBinding.ensureInitialized();
await initMMKV();
await _queryAppInfo();
await CameraChecker.getInstance().startCheck();
await _init();
await _initAppEnv();
}
Through the following output log, you will find that the code "startAppInit" has no output.
Then, the output log in Logcat：
