Android: java.lang.IllegalStateException: GoogleApiClient must be connected

I am integrating Google Plus into my android app, when I tried to log into Google Plus my app just crashed. It says -

java.lang.IllegalStateException: GoogleApiClient must be connected

Following is the number of lines that the stack points to,

if (Plus.AccountApi.getAccountName(mGoogleApiClient) != null)

@Override
    public void onConnected(Bundle connectionHint) {
        String personName = "Unknown";
        if (Plus.AccountApi.getAccountName(mGoogleApiClient) != null) {
            personName = Plus.AccountApi.getAccountName(mGoogleApiClient); 
        }
}

I took all the steps to integrate, added google services to my project and registered my app with the google API site.

First check if it's connected and then do your stuff.



GoogleApiClient mGoogleApiClient;
if(mGoogleApiClient.isConnected()){
  // good
}else{
  //connect it
  mGoogleApiClient.connect(GoogleApiClient.SIGN_IN_MODE_OPTIONAL);
}

Anyway, change your code to:



@Override
    public void onConnected(Bundle connectionHint) {
        String personName = "Unknown";
        if (isSignedIn()) {
          if (Plus.AccountApi.getAccountName(mGoogleApiClient) != null) {
            personName = Plus.AccountApi.getAccountName(mGoogleApiClient); 
          }
        }
}
