I try to learn how i can use google sign in in my android App, but i catch com.google.android.gms.common.api.ApiException: 16 And i can't find on stackoveflow answer, what is it and why i catch it. In documentation i read, what it "was canceled by user", but my google account accepted to install apps
import android.support.v7.app.AppCompatActivity
import android.os.Bundle
import android.util.Log
import com.google.android.gms.auth.api.signin.GoogleSignIn
import com.google.android.gms.auth.api.signin.GoogleSignInOptions
import com.google.android.gms.auth.api.signin.GoogleSignInAccount
import android.content.Intent

import com.google.android.gms.common.api.ApiException
class MainActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val gso = GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build()
val mGoogleSignInClient = GoogleSignIn.getClient(this, gso)
val account = GoogleSignIn.getLastSignedInAccount(this)
if(account != null){
Log.e("!!!", account.email)
} else {
val signInIntent = mGoogleSignInClient.signInIntent
startActivityForResult(signInIntent, 0)
}
}
public override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == 0) {
// The Task returned from this call is always completed, no need to attach
// a listener.
val task = GoogleSignIn.getSignedInAccountFromIntent(data)
handleSignInResult(task)
}
}
private fun handleSignInResult(completedTask: Task<GoogleSignInAccount>) {
try {
val account = completedTask.getResult(ApiException::class.java)
// Signed in successfully, show authenticated UI.
Log.e("!!!", account.email)
} catch (e: ApiException) {
e.printStackTrace()
}
}
}
I followed this guide . Did the configuration of the project. If it's matter, i use VDS for this. Account was created in the same place
Here is stackTrace:

I had the same problem, start activity result kept coming back with RESULT_CANCELED and errorCode 16. The problem was my client configuration in Google Cloud Platform Console. I was using the regular debug and release api key. The result came back OK
when I used web application as my Google Console configuration.
Hope it helps.
Was having the same problem, turns out I did not set support mail on firebase project settings .
If this is the case, firebase will show you edit project settings when trying to enable Google sign in on Firebase Authentication . You can copy your client Id from firebase
Maybe a bit late to the party here but after more than 4 hours debugging I realized that:
1.- Add an Android client with your signing-certificates fingerprints under the OAuth client IDs list. This is mandatory.
2.- Add the Web application client ID in your code in case your need to get an id token
// ID and basic profile are included in DEFAULT_SIGN_IN
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken("YOUR_CLIENT_ID")
.requestEmail()
.build();
Hope it helps
For me the only thing that worked was to provide 2 oauth client ids . a web application client id AND an android client id
In my android app i use the client id and client secret of the web application. Even though i don't use the android client id anywhere in my app it is still required. ie if i delete the oauth android client in the google api console my app stops working EVEN THOUGH i dont use that client id ANYWHERE in my app.
this makes absolutely no sense to me! go figure . but so far this is the only thing that has worked.
un-freaking-believable.
I am developing an Android application using Flutter, tried to integrate Google Sign In and faced the same problem with ApiException: 16 and SIGN_IN_FAILED (instead of RESULT_CANCELED).
Application type on Firebase was set to android.
In my case, after many hours of debugging, it turned out to be a wrong SHA-1 problem .
As soon as I extracted the SHA-1 key from my project and updated Firebase console, it worked.
我使用了一个不同的 oauth id 密钥,这是我从下载项目设置中找到的,并在项目中添加了客户端 3 密钥。
