I'm making an Android project, and for starters I have been figuring out how signing up works. By the way, I used Firebase for this. Here's my code:
package com....
import...
public class MainActivity extends AppCompatActivity {
//VIEW AND WIDGETS
Button createUser, moveToLoginBtn;
EditText userEmailEdit, userPasswordEdit;
//FIREBASE AUTH FIELDS
FirebaseAuth nAuth;
FirebaseAuth.AuthStateListener nAuthlistener;
DatabaseReference mDatabaseRef, mUserCheckData;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//ASSIGN ID
createUser = (Button) findViewById(R.id.createUserBtn);
moveToLoginBtn = (Button) findViewById(R.id.moveToLogin);
userEmailEdit = (EditText) findViewById(R.id.emailEditTextCreate);
userPasswordEdit = (EditText) findViewById(R.id.passEditTextCreate);
//ASSIGN INSTANCE
mDatabaseRef = FirebaseDatabase.getInstance().getReference();
mUserCheckData = FirebaseDatabase.getInstance().getReference().child("Users");
nAuth = FirebaseAuth.getInstance();
nAuthlistener = new FirebaseAuth.AuthStateListener(){
@Override
public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
FirebaseUser user = firebaseAuth.getCurrentUser();
if (user != null) {
final String emailForVer = user.getEmail();
mUserCheckData.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(DataSnapshot dataSnapshot) {
checkUserValidation(dataSnapshot, emailForVer);
}
@Override
public void onCancelled(DatabaseError databaseError) {
}
});
} else {
}
}
};
//ON CLICK LISTENER
createUser.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view) {
final String userEmailString, userPassString;
userEmailString = userEmailEdit.getText().toString().trim();
userPassString = userPasswordEdit.getText().toString().trim();
if (!TextUtils.isEmpty(userEmailString) && !TextUtils.isEmpty(userPassString))
{
nAuth.createUserWithEmailAndPassword(userEmailString,userPassString).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
@Override
public void onComplete(@NonNull Task<AuthResult> task) {
if (task.isSuccessful())
{
DatabaseReference mChildDatabase = mDatabaseRef.child("Users").push();
String key_user = mChildDatabase.getKey();
mChildDatabase.child("isVerified").setValue("unverified");
mChildDatabase.child("userKey").setValue(key_user);
mChildDatabase.child("emailUser").setValue(userEmailString);
mChildDatabase.child("passWordUser").setValue(userPassString);
Toast.makeText(MainActivity.this, "User Account Created!", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, Profile.class));
}
else
{
Toast.makeText(MainActivity.this, "User Account Creation Fail", Toast.LENGTH_LONG).show();
startActivity(new Intent(MainActivity.this, MainActivity.class));
}
}
});
}
}
});
//MOVE TO LOGIN
moveToLoginBtn.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View view){
startActivity(new Intent(MainActivity.this, LoginActivity.class));
}
});
}
private void checkUserValidation(DataSnapshot dataSnapshot, String emailForVer) {
Iterator iterator = dataSnapshot.getChildren().iterator();
while (iterator.hasNext())
{
DataSnapshot dataUser = (DataSnapshot) iterator.next();
if(String.valueOf(dataUser.child("emailUser").getValue()).equals(emailForVer) && dataUser.child("emailUser") != null)
{
if(String.valueOf(dataUser.child("isVerified").getValue()).equals("unverified") && dataUser.child("isVerified") != null)
{
Intent in = new Intent(MainActivity.this, Profile.class);
in.putExtra("USER_KEY" , String.valueOf(dataUser.child("userKey").getValue()));
startActivity(in);
//in.putExtra("NAME_KEY" , String.valueOf(dataUser.child("nameKey").getValue()));
}else
{
startActivity(new Intent(MainActivity.this, Welcome.class));
}
}
}
}
@Override
protected void onStart() {
super.onStart();
nAuth.addAuthStateListener(nAuthlistener);
}
@Override
protected void onStop() {
super.onStop();
nAuth.removeAuthStateListener(nAuthlistener);
}
}
I think I have implemented my methods correctly. But it toasts:
User Account Creation Failed
Is my
checkUseValidation() method wrong? Any kind of help is appreciated.
Also please pay attention to my:
public void onComplete
method, I have set it right I think. I don't know why the data isn't getting saved to the firebase database. Or why is the task unsuccesful as show in line:
if (task.isSuccessful())
Thank you very much.
