passing the GoogleApiClient obj from one activity to another

Question

I want to be able to update my score for my leaderboard in a different activity other than the one that creates the GoogleApiClient obj ( the main activity ).

What is th

Answer 1

My real test is: 1. Can not pass an GoogleApiClient as an object to another service or activity, by using it as a Intent parameter. 2. Let use Singleton class solve it as below: + Step 1: Make Singleton class which include GoogleApiClient object as data member. Please do like this:

import com.google.android.gms.common.api.GoogleApiClient;

public class MyGoogleApiClient_Singleton {
    private static final String TAG = "MyGoogleApiClient_Singleton";
    private static MyGoogleApiClient_Singleton instance = null;

    private static GoogleApiClient mGoogleApiClient = null;

    protected MyGoogleApiClient_Singleton() {

    }

    public static MyGoogleApiClient_Singleton getInstance(GoogleApiClient aGoogleApiClient) {
        if(instance == null) {
            instance = new MyGoogleApiClient_Singleton();
            if (mGoogleApiClient == null)
                mGoogleApiClient = aGoogleApiClient;
        }
        return instance;
    }

    public GoogleApiClient get_GoogleApiClient(){
        return mGoogleApiClient;
    }
}   

• Step 2: In main Activity class do initialize a GoogleApiClient object then call getInstance with mGoogleApiClient as a parameter of Singleton base class.

• Step 3: In another service/Activity which you want to pass GoogleApiClient object to, just call getInstance(null) of Singleton baseclass, and call get_GoogleApiClient to get desired GoogleApiClient object.
