如何从Google登录退出？

Question

According to google docx we have two methods

• SingOut
• RevokeAccess

I need second one

For this way google provide such method

public void revokeAccess() {
    GoogleSignInOptions gso = getGoogleSignInOptions();
    mGoogleApiClient = getGoogleApiClient(gso);
    if (mGoogleApiClient.isConnected()) {
        Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
                new ResultCallback<Status>() {
                    @Override
                    public void onResult(@NonNull Status status) {
                        Logger.log(GoogleImplementation.class, "signOut:onResult:" + status, Logger.ERROR);
                    }
                });
    } else {
        Logger.log(GoogleImplementation.class, "GoogleApiClient is not connected yet.", Logger.ERROR);
    }
}

But everytime when i try to invoke it i get error

GoogleApiClient is not connected yet.

I found the same issue on stack and according to this as far as i understand i have to invoke revokeAccess() on the same object which i made LogIn()

Therefore question how i can to save this object? Or i misunderstand the consept?

What am i doing wrong?

EDIT

@NonNull
public GoogleApiClient getGoogleApiClient(GoogleSignInOptions gso) {
    return new GoogleApiClient.Builder(context)
            .enableAutoManage(activity, listenerConnection)   <-----
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .build();
}

EDIT 2

public void revokeAccess() {
    GoogleSignInOptions gso = getGoogleSignInOptions();
    mGoogleApiClient = getGoogleApiClient(gso);
    if (mGoogleApiClient.isConnected()) {
        Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
                new ResultCallback<Status>() {
                    @Override
                    public void onResult(@NonNull Status status) {
                        Logger.log(GoogleImplementation.class, "signOut:onResult:" + status, Logger.ERROR);
                    }
                });
    } else {
        mGoogleApiClient.connect();
        Logger.log(GoogleImplementation.class, "GoogleApiClient is not connected yet.", Logger.ERROR);
        Auth.GoogleSignInApi.revokeAccess(mGoogleApiClient).setResultCallback(
                new ResultCallback<Status>() {
                    @Override
                    public void onResult(@NonNull Status status) {
                        Logger.log(GoogleImplementation.class, "signOut:onResult:" + status, Logger.ERROR);
                    }
                });
    }
}

在每个不同的活动中，您应该连接您的GoogleApiClient，它不会跨活动保持连接状态。
