Data does not save in Firebase

Question

I’m trying to save data in my Firebase database but the app doesn’t save. I can install, boot the app, and move between pages without an app crash, but I can’t save data.

Before implementing the material design was managing to save the data, now I can no longer save.

From what I’ve already researched it seems to be some problem with the Firebase connection, as it apparently disconnects while the app is running. But I couldn’t find a solution that worked.

I’m using:

• Java Android
• Material Design for Android (Java)

What I’ve already tried:

• Swap Splash Screen image from drawable folder to xxx-hpi mipmap folder;
• I deleted the project cache;
• I checked the size of the project, but it’s not very big yet, because I don’t use Fragment or very complex things yet;
• I uninstalled the app and installed again

Firebase is connected to the project and with Rule write:true
