我有一个系统可以将 createUserWithEmailAndPassword 数据保存到实时数据库和身份验证数据库中。但是在使用谷歌登录创建了一个类似的系统之后，没有任何内容会保存到数据库中，也没有任何内容保存到身份验证数据库中。
我试过使用 Log.e，我试过调试应用程序，也试过解码代码...
这里是一些代码:

}
@Override

super.onActivityResult(requestCode, resultCode, data);
int RC_SIGN_IN = 100;
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {

// The ApiException status code indicates the detailed failure reason.
// Please refer to the GoogleSignInStatusCodes class reference for more information.
Toast.makeText(this, "Log in failed", Toast.LENGTH_SHORT).show();
Log.e(Tag, "error: ");
startActivity(new Intent(LoginOrSignupActivity.this, AccountInfoActivity.class));
}
}
void SaveToDataBase(){
database.addListenerForSingleValueEvent(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
GoogleSignInAccount Guser = GoogleSignIn.getLastSignedInAccount(LoginOrSignupActivity.this);
String EmailWithEtheraRemoved = Guser.getEmail().replace(".", " ");
if(!(dataSnapshot.child("Users").child(EmailWithEtheraRemoved).exists())){
LoadingBar.setMessage("Please wait while we load the credentialls in");
LoadingBar.setTitle("Register");
LoadingBar.setCanceledOnTouchOutside(false);
LoadingBar.show();
HashMap<String, Object> Userdatamap = new HashMap<>();
Userdatamap
.put("Email", Guser.getEmail());
Userdatamap
.put("Phone number", "Google intigrated sign in does not allow phone number requesting... This will be fixed in later patches");
Userdatamap
.put("Name", Guser.getGivenName() + Guser.getFamilyName());
if(Guser != null){
Userdatamap
.put("Created with", "Intigrated Google sign in");
}
database
.child("Users")
.child(EmailWithEtheraRemoved)
.updateChildren(Userdatamap)
.addOnCompleteListener(new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
LoadingBar.dismiss();
Toast.makeText(LoginOrSignupActivity.this, "Database save successful", Toast.LENGTH_SHORT).show();
Log.e("SignUpError :", task
.getException()
.getMessage());
}
}).addOnFailureListener(new OnFailureListener() {
@Override
public void onFailure(@NonNull Exception e) {
Toast.makeText(LoginOrSignupActivity.this, "Registration failed", Toast.LENGTH_SHORT).show();
Log.e(Tag, "error: ");
}
});
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
}
void LoadinGUI(){
LoginBtn = (Button) findViewById(R. id. Login_btn);
RegisterWithEmailBtn = (Button) findViewById(R. id. Register_WithEmail_btn);
RegisterWithGoogleBtn = (Button) findViewById(R. id. Register_WithGoogle_btn);
}
}
我希望应用程序将信息保存到实时数据库和身份验证数据库中。这些似乎都不起作用......
最佳答案
登录成功后忘记调用SaveToDataBase。这就是为什么没有日志和数据库条目的原因。
关于java - Firebase Auth 和 Firebase 数据库不保存 Google 注册，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/56957729/
