公共类 MainActivity 扩展 Activity {

protected static final String TAG = "Kinvey Testing ";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

   final Client mKinveyClient = new Client.Builder(this.getApplicationContext()).build();


    mKinveyClient.ping(new KinveyPingCallback() 
    {
      public void onFailure(Throwable t) {
            Log.e(TAG, "Kinvey Ping Failed", t);
      }
       public void onSuccess(Boolean b) {
           Log.d(TAG, "Kinvey Ping Success");
        }
    });


}
