Java 没有Google Play服务，Firebase Auth无法工作

由于try 使用Firebase AuthUI登录时出错，我的应用程序被Amazon Appstore拒绝.

我决定做一些研究，发现所有亚马逊Fire设备都没有运行Google Play服务.我安装了一个没有谷歌服务的新模拟器，也得到了一个错误.

奇怪的是，Firebase Auth的20.0.0版引入了"The Firebase Authentication Android library now works on devices without Google Play services."功能.

代码

public void signIn() {
    List<AuthUI.IdpConfig> listProviders = Arrays.asList(
            new AuthUI.IdpConfig.GoogleBuilder().build(),
            new AuthUI.IdpConfig.FacebookBuilder().build(),
            new AuthUI.IdpConfig.TwitterBuilder().build(),
            new AuthUI.IdpConfig.YahooBuilder().build(),
            new AuthUI.IdpConfig.EmailBuilder().build()
    );

    // Create and launch sign-in intent
    Intent intentSignIn = AuthUI.getInstance()
            .createSignInIntentBuilder()
            .setAvailableProviders(listProviders)
            .setTheme(R.style.LoginTheme)
            .setLogo(R.drawable.login_icon)
            .setTosAndPrivacyPolicyUrls(
                    "URL",
                    "URL")
            .build();
    activityResultLauncherSignIn.launch(intentSignIn);
}

// https://developer.android.com/training/basics/intents/result
private final ActivityResultLauncher<Intent> activityResultLauncherSignIn = registerForActivityResult(
        new FirebaseAuthUIActivityResultContract(),
        this::onSignInResult
);

private void onSignInResult(FirebaseAuthUIAuthenticationResult firebaseAuthUIAuthenticationResult) {
    IdpResponse idpResponse = firebaseAuthUIAuthenticationResult.getIdpResponse();
    if (firebaseAuthUIAuthenticationResult.getResult代码() == RESULT_OK) {
        if (firebaseUser != null && firebaseUser.getEmail() != null && !firebaseUser.isEmailVerified())
            sendVerificationEmail();
    } else {
        // Sign in failed. If response is null the user canceled the sign-in flow using the back button. Otherwise check response.getError().getError代码() and handle the error.
        if (idpResponse != null && idpResponse.getError() != null) {
            Log.e(TAG, "Problem with Firebase authentication: " + idpResponse.getError().getError代码());
        }
    }
}

错误: Firebase身份验证问题:0
