public class GmailSignin extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener{
    TextView signInButton;
    private GoogleApiClient mGoogleApiClient;
    private static final int RC_SIGN_IN = 9001;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
                .requestEmail()
                .build();

    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();


    signInButton = (TextView) findViewById(R.id.sign_in_button);
    signInButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            signIn();
        }
    });
}


 void signIn() {
    Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        handleSignInResult(result);
    }
}

private void handleSignInResult(GoogleSignInResult result) {
    Log.d("Signin", "handleSignInResult:" + result.isSuccess());
    if (result.isSuccess()) {
        // Signed in successfully, show authenticated UI.
        GoogleSignInAccount acct = result.getSignInAccount();
        Conatants.name=acct.getDisplayName();
        Conatants.email=acct.getEmail();
        Conatants.id=acct.getId();
        Intent intent=new Intent(getApplicationContext(),Details.class);
        startActivity(intent);

    } else {
        // Signed out, show unauthenticated UI.
    }
}


@Override
public void onConnectionFailed(ConnectionResult connectionResult) {

}
public void onStart(){
    OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);

    if (opr.isDone()) {
        // If the user's cached credentials are valid, the OptionalPendingResult will be "done"
        // and the GoogleSignInResult will be available instantly.
        Log.d("gmailsignup", "Got cached sign-in");
        GoogleSignInResult result = opr.get();
        handleSignInResult(result);
    } else {
        // If the user has not previously signed in on this device or the sign-in has expired,
        // this asynchronous branch will attempt to sign in the user silently.  Cross-device
        // single sign-on will occur in this branch.
        opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
            @Override
            public void onResult(GoogleSignInResult googleSignInResult) {
                handleSignInResult(googleSignInResult);
            }
        });
    }
}
}
