I want to save data to firebase. This is my Activity Code :
private Firebase firebaseRef;
Firebase.setAndroidContext(this);
try {
mUserId = firebaseRef.getAuth().getUid();
} catch (Exception e) {
// loginWithMailView();
}
itemsUrl = Constants.FIREBASE_URL + "/Person/" + mUserId +"/Information/";
//Person + null (?) + the other information
and this is for my button code :
buttonSave = (Button) findViewById(R.id.btnKaydolKayit);
buttonSave.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
firebaseRef = new Firebase(Constants.FIREBASE_URL);
String name = editTextName.getText().toString().trim();
String surname = editTextSurname.getText().toString().trim();
String gender = final_result.getText().toString();
String mail = editTextMail.getText().toString();
String pass = editTextPass.getText().toString().trim();
String phone = editTextPhone.getText().toString().trim();
String trom = final_resultT.getText().toString();
String bloodGroup = spinnerBlood.getSelectedItem().toString();
String dateBlood = dateTextViewBlood.getText().toString();
String dateTrombo = dateTextViewTrom.getText().toString();
if (pass.isEmpty() || mail.isEmpty()) {
AlertDialog.Builder builder = new AlertDialog.Builder(KaydolActivity.this);
builder.setMessage(R.string.signup_error_message)
.setTitle(R.string.signup_error_title)
.setPositiveButton(android.R.string.ok, null);
AlertDialog dialog = builder.create();
dialog.show();
} else {
firebaseRef.createUser(mail, pass, new Firebase.ResultHandler(){
@Override
public void onSuccess() {
firebaseRef = new Firebase(Constants.FIREBASE_URL);
// firebaseRef.setValue();
AlertDialog.Builder builder = new AlertDialog.Builder(KaydolActivity.this);
builder.setMessage("Hesap başarılı bir şekilde oluşturuldu!").setPositiveButton(R.string.login_button_label, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialogInterface, int i) {
Intent intent = new Intent(KaydolActivity.this, loginWithMail.class);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
}
});
AlertDialog dialog = builder.create();
dialog.show();
}
@Override
public void onError(FirebaseError firebaseError) {
AlertDialog.Builder builder = new AlertDialog.Builder(KaydolActivity.this);
builder.setMessage(firebaseError.getMessage())
.setTitle(R.string.signup_error_title)
.setPositiveButton(android.R.string.ok, null);
AlertDialog dialog = builder.create();
dialog.show();
}
});
}
new Firebase(itemsUrl).push().child("name").setValue(name);
new Firebase(itemsUrl).push().child("surname").setValue(surname);
new Firebase(itemsUrl).push().child("gender").setValue(gender);
new Firebase(itemsUrl).push().child("mail").setValue(mail);
new Firebase(itemsUrl).push().child("pass").setValue(pass);
new Firebase(itemsUrl).push().child("phone").setValue(phone);
new Firebase(itemsUrl).push().child("trom").setValue(trom);
new Firebase(itemsUrl).push().child("bloodGroup").setValue(bloodGroup);
new Firebase(itemsUrl).push().child("trom").setValue(trom);
new Firebase(itemsUrl).push().child("dateBlood").setValue(dateBlood);
new Firebase(itemsUrl).push().child("dateTrombo").setValue(dateTrombo);
}
});

When I save a data to firebase as the following photo ( Login&Auth )
but mUserId is null. so when I look database mUserid is null ( like a photo )
You can use these lines of code to get Current User Uid with Android Firebase Framework
FirebaseUser currentFirebaseUser = FirebaseAuth.getInstance().getCurrentUser() ;
Toast.makeText(this, "" + currentFirebaseUser.getUid(), Toast.LENGTH_SHORT).show();
To get Current User UID, you just need this line of code:
String currentuser = FirebaseAuth.getInstance().getCurrentUser().getUid();
the problem is that in firebase when you create a user it doesn't sign in the user. Here is from the docs:
Creates a new email / password user with the provided credentials. This method does not authenticate the user. After the account is created, the user may be authenticated with authWithPassword(). https://www.firebase.com/docs/web/api/firebase/createuser.html
Firebase ref = new Firebase("https://<YOUR-FIREBASE-APP>.firebaseio.com");
ref.authWithPassword(mail, pass, new Firebase.AuthResultHandler() {
@Override
public void onAuthenticated(AuthData authData) {
System.out.println("User ID: " + authData.getUid() + ", Provider: " + authData.getProvider());
}
@Override
public void onAuthenticationError(FirebaseError firebaseError) {
// there was an error
}
});
So once your user is created call the authWithPassword function. Hope it helps!
