Hi everyone I’m developing an app that uses the firebase database.

My problem is that I’m tempting the value of 29.90 in one of my database.

Ex:

Value of product: 29.90

I want to take this value within my internal program.

String value = datasnapshot.Chil("Product value"). getValue(String.class);

However, my program closes.

I tried to pass the value on firebase in the following ways: 29.90 and "29.90" but none worked.

Could the problem be "."?

So if you’re putting exactly this line of code, the problem could be the "d" missing in "Child," then it should be:

String valor = datasnapshot.child("Valor do produto").getValue();

    Thanks friend but I solved the problem...... The error was in another variable in firebase Altime.

  • Ex: I had in Realtime data base a string that stored an address of an image on the internet, but I didn’t realize it was empty. The problem was that I was using the Picasso library.

  • I took the firebase value and stored it in an internal string and passed it to the Picasso library. Picasso.get(). load(" "). Into(imageView); > Gives error if pass empty load
