Android Firebase OnCompleteListener not working
0
I am building a code where I want to save some data in Firebase database. The database reference is databasereference and unique is databasereference.push().
The problem is the code seems to work until the OnCompleteListener. Then it seems to stop.
The code is:
databaseReference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
String name = dataSnapshot.child("firstname").getValue().toString() + " " + dataSnapshot.child("lastname").getValue().toString();
unique.child("name").setValue(name).addOnCompleteListener(
new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if(task.isSuccessful()){
unique.child("UserId").setValue(userId);
int ts = (int) (System.currentTimeMillis()/1000);
unique.child("time").setValue(0-ts);
}
}
}
);
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
Here the database is only storing child name. If we modify the code like this:
databaseReference.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
String name = dataSnapshot.child("firstname").getValue().toString() + " " + dataSnapshot.child("lastname").getValue().toString();
unique.child("UserId").setValue(userId);
int ts = (int) (System.currentTimeMillis()/1000);
unique.child("time").setValue(0-ts);
unique.child("name").setValue(name).addOnCompleteListener(
new OnCompleteListener<Void>() {
@Override
public void onComplete(@NonNull Task<Void> task) {
if(task.isSuccessful()){
unique.child("somethingElse").setValue("something else");
}
}
}
);
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
In this case it stores userId, time, name but not the somethingElse.

You should add a message to see if your listener is called, also you may be getting an error (add log for the case where the task is not successful).
