Google Auth迁移到androidx:SignInHubActivity不实现Lifecycle

Question

迁移到AndroidX后,我面临以下问题与Google Auth lib:

在Android 9 API 28上:

java.lang.IncompatibleClassChangeError: Class 'com.google.android.gms.auth.api.signin.internal.SignInHubActivity' does not implement interface 'androidx.lifecycle.LifecycleOwner' in call to 'androidx.lifecycle.Lifecycle androidx.lifecycle.LifecycleOwner.getLifecycle()' (declaration of 'androidx.lifecycle.LiveData' appears in /data/app/fourbottles.bsg.workinghours4b-G1onPKgFFE-l3aqjx0qDJw==/split_lib_dependencies_apk.apk)

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:858)

在Android 5.0.2 API 22上

Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'androidx.lifecycle.Lifecycle$State androidx.lifecycle.Lifecycle.getCurrentState()' on a null object reference

    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:694)

我使用以下lib版本:

implementation 'com.google.android.gms:play-services-gcm:16.0.0'
implementation 'com.google.android.gms:play-services-auth:16.0.1'
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'androidx.multidex:multidex:2.0.1'

一旦我开始具有意图的活动,代码就会崩溃:

val signInIntent = Auth.GoogleSignInApi.getSignInIntent(googleApiClient)
startActivityForResult(signInIntent, LOGIN_WITH_GOOGLE_CODE)

我在settings.gradle文件中有以下属性:

android.useAndroidX=true
android.enableJetifier=true

Google Auth lib不支持使用AndroidX libs进行身份验证吗？

有没有办法从支持lib行为的androidX lib启动一个意图？  

我接受java和kotlin语言的答案.

更新1:27.12.2017

Google api客户端创建:

 GoogleSignInOptions googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestIdToken(getString(R.string.default_web_client_id))
                .requestEmail()
                .build();

 googleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this, this)
                .addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions)
                .build();

可能是因为enableAutoManage？

更新2:28.12.2018

我设法使用以下代码登录:

Task<GoogleSignInAccount> sign = googleSignInClient.silentSignIn();
GoogleSignInAccount result = sign.getResult();

所以我认为凭证或其他配置文件没有问题.这样,用户将无法选择帐户.

我认为Jetifier以同样的方式失败了.

使用API​​ 27我得到了同样的错误.

Answer 1

我通过使用最新版本的appcompat库解决了此问题：

implementation "androidx.appcompat:appcompat:1.1.0-rc01"

在以前的版本中，类AppCompatActivity没有实现LifecycleOwner接口，因此导致您观察到错误。

Answer 2

同样的问题！我刚刚添加了“核心”依赖项，并将“ appcompat”更改为最新的alpha版本，它有所帮助。

dependencies {

implementation "androidx.core:core:1.1.0-alpha03"
implementation "androidx.legacy:legacy-support-v4:1.0.0"
implementation "androidx.annotation:annotation:1.0.1"
implementation "androidx.recyclerview:recyclerview:1.1.0-alpha01"
implementation "androidx.appcompat:appcompat:1.1.0-alpha01"
implementation 'androidx.constraintlayout:constraintlayout:1.1.3'
implementation "androidx.cardview:cardview:1.0.0"
implementation "com.google.android.material:material:1.1.0-alpha02"

implementation "com.google.firebase:firebase-core:16.0.6"
implementation "com.google.firebase:firebase-auth:16.1.0"
implementation "com.google.firebase:firebase-storage:16.0.5"
implementation "com.google.firebase:firebase-perf:16.2.3"
implementation 'com.firebaseui:firebase-ui-database:4.3.0'

implementation "com.google.android.gms:play-services-auth:16.0.1"
implementation "com.google.android.gms:play-services-location:16.0.0"
implementation "com.google.android.gms:play-services-maps:16.0.0"
...
}

我用：

compileSdkVersion 28
buildToolsVersion "28.0.3"

顶级gradle.build：

dependencies {
    classpath 'com.android.tools.build:gradle:3.3.0'
    classpath 'com.google.gms:google-services:4.2.0'
    ...
}

gradle.properties：

android.debug.obsoleteApi=true
android.enableR8 = true
android.useAndroidX=true
android.enableJetifier=true

gradle包装器的gradle版本设置为gradle-4.10.1-all.zip。我也尝试使AS 3.3 无效/重新启动。希望它能帮助到别人。
