我在使用Google+登录时使用Firebase身份验证，点击登录按钮后，页面刷新（？）并且永远不会调用onActivityResult ...
在有人要求之前，Firebase Google登录已启用，我的SHA-1已添加且正确无误，我的google-services.json已添加并且是最新的。
一些更奇怪的行为：在卸载我的应用程序然后重新运行它之后，单击登录按钮后出现了选择用户的对话框。它在大约2秒后消失，从未恢复过来。

我尝试尽可能保持代码尽可能接近Firebase / Google Auth示例，以避免出现问题，因此我很遗憾这里出了什么问题。这是我的退出代码，以防引起问题：
// [START configure_signin]
// Configure sign-in to request the user's ID, email address, and basic
// profile. ID and basic profile are included in DEFAULT_SIGN_IN.
GoogleSignInOptions gso = new
GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
// [END configure_signin]
// [START build_client]
// Build a GoogleApiClient with access to the Google Sign-In API and the
// options specified by gso.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
// [END build_client]
signOutButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
mAuth.signOut();
Auth.GoogleSignInApi.signOut(mGoogleApiClient);
Intent intent = new Intent(v.getContext(), LoginActivity.class);
startActivity(intent);
}
});
任何帮助非常感谢
编辑：只是为了添加更多信息，我之所以做的不仅仅是
mAuth.signOut();
注销是因为我需要后续的登录对话框来始终询问哪个用户登录，并且添加额外的注销内容是我发现实现这一目标的唯一方法。同样，不确定该代码是否相关，但希望它有所帮助。

固定！我完全复制了Quickstart代码，现在登录工作。我不知道为什么，但我会想出来
