huawei-mobile-services - 华为 Push Kit Flutter：Push.getToken() 返回 ResultCode -5

问题描述

当我查看文档时，它告诉 -5 与 proguard 规则有关，因此我按照此处所述添加了它们。 https://developer.huawei.com/consumer/en/doc/development/HMSCore-References-V5/error-code-0000001050255690-V5

android/proguard-rules.pro

## Flutter wrapper
-keep class io.flutter.app.** { *; }
-keep class io.flutter.plugin.**  { *; }
-keep class io.flutter.util.**  { *; }
-keep class io.flutter.view.**  { *; }
-keep class io.flutter.**  { *; }
-keep class io.flutter.plugins.**  { *; }
-dontwarn io.flutter.embedding.**

## HMS Core SDK
-ignorewarnings
-keepattributes *Annotation*
-keepattributes Exceptions
-keepattributes InnerClasses
-keepattributes Signature
-keepattributes SourceFile,LineNumberTable
-keep class com.huawei.hianalytics.**{*;}
-keep class com.huawei.updatesdk.**{*;}
-keep class com.huawei.hms.**{*;}

android/app/build.gradle 部分：

buildTypes {
        release {
            // TODO: Add your own signing config for the release build.
            // Signing with the debug keys for now, so `flutter run --release` works.
            signingConfig signingConfigs.release
            useProguard true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }

这是代码初始化和获取令牌部分：

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {


  String _token = '';

  @override
  void initState() {
    HwAds.init();
    initPush();
    super.initState();
  }

  Future<void> initPush() async {
    if (!mounted) return;
    Push.getTokenStream.listen(_onTokenEvent, onError: _onTokenError);
  }

  void _onTokenEvent(String event) {
    print('onTokenEvent');
    _token = event;
    showResult("TokenEvent", _token);
  }

  void _onTokenError(Object error) {
    print('onTokenError');
    PlatformException e = error;
    showResult("TokenErrorEvent", e.message);
  }

  void showResult(String name, [String msg = "Button pressed."]) {
    print('$name: $msg');
    if (msg.isNotEmpty) Push.showToast(msg);
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Home'),
      ),
      body: SingleChildScrollView(
        child: Column(
          children: [
            RaisedButton(
              child: Text('Interstitial Ad Page'),
              onPressed: ()=> Navigator.pushNamed(context, '/interstitialPage'),
            ),
            RaisedButton(
              child: Text('Get token'),
              onPressed: ()=> Push.getToken(''),
            ),
          ],
        ),
      ),
    );
  }
}

我正在使用云调试，型号名称是 P40。我创建了一个发布 apk，选择了数据存储位置，提供了 SHA256，启用了 Push Kit，启用了 push kit 后更新了 agconnect-services。还有什么我想念的吗？
