Error:Execution failed for task ':app:packageDebug'. > !zip.isFile()

Question

@UPDATE

Thank you very much. Now at least there are no errors. But it's still a far cry from how it worked before - how it should work. Now, the database looks ... strange. I think that something is still wrong with this gradle.

It should not look like. According to the java code in the database will be user and its data (name, email, date of account creation, id avatar)

In the application at the site next to the avatar you should display the name. Unfortunately, as you can see nothing happens. There is nothing wrong with the code because it previously worked. :(

I ruined my project! I tried to fix it but now it's worse than it was.

The project is chat client through Firebase.

It started when I deleted my base. I had too many test users, messages I wanted to clear it. Since then, it gets a million error notifications - trying to fix one thing leads to even worse errors.

I tried to connect to the application completely different base, I tried to re-arrange a few things. Nothing helps.

At first I thought that the problem is with wrong compile 'com.google.firebase:firebase-database:9.8.0' number. Then I received

E/FirebaseApp: Firebase API initialization failure.

I try to fix it. Application was started and in the database was very strange things.

Now i get

Error:Execution failed for task ':app:packageDebug'.> !zip.isFile()

Clean and Rebuild project should work. It work for me. Look at this: https://code.google.com/p/android/issues/detail?id=230211
