我正在按照https://firebase.google.com/docs/auth/android/firebaseui
中的说明实施用于Firebase身份验证的预构建UI。基本上，我的应用程序上发生的事情是成功登录后，我的应用程序被移至后台，这导致无法调用onActivityResult方法。但是，我不知道发生这种情况的原因是什么。
我正在使用最新版本的FirebaseUI，Google Play Auth和Firebase依赖项，如我应用程序的build.gradle文件中所示。
我遇到了很多问题，这些问题现在都不是一个问题。就像有不正确的SHA-1（在点击登录按钮后导致错误）或缺少依赖项一样。
我尝试生成一个发行版APK，以防调试APK发生某些事情，但结果是相同的。
对此有任何帮助吗？
经过大量测试，我发现唯一看起来不太好的是出现在logcat中的错误：
[DeviceKeyStore]无法加载密钥：找不到设备密钥文件。
这是我用来调用FirebaseUI库的代码：
override fun onResume() {
super.onResume()
val mAuth = FirebaseAuth.getInstance()
val currentUser = mAuth?.currentUser
if (currentUser == null) {
requireFirebaseLogin()
}
}
private fun requireFirebaseLogin() {
val providers = arrayListOf(
AuthUI.IdpConfig.AnonymousBuilder().build(),
AuthUI.IdpConfig.EmailBuilder().build(),
AuthUI.IdpConfig.FacebookBuilder().build(),
AuthUI.IdpConfig.GoogleBuilder().build())
startActivityForResult(
AuthUI.getInstance()
.createSignInIntentBuilder()
.setAvailableProviders(providers)
.setLogo(R.mipmap.logo)
.build(),
RequestCodes.FIREBASE_SIGN_IN)
}
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (requestCode == RequestCodes.FIREBASE_SIGN_IN) {
val response = IdpResponse.fromResultIntent(data)
if (resultCode == Activity.RESULT_OK) {
mapApplication.firebaseAuth = mAuth
initSetup()
} else {
// Sign in failed. If response is null the firebaseAuth canceled the
// sign-in flow using the back button. Otherwise check
// response.getError().getErrorCode() and handle the error.
}
}
}
