Android - CookieSyncManager to prevent Webview lost session after Pause Resume

By adding CookieSyncManager onCreate of Activity and also on corresponding events like onPause and onResume, taking care my session ID for the PHP server when the Activity/WebView reloads.

public class MainActivity extends Activity {
    @Override
     protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);
           setContentView(R.layout.activity_main);

           CookieSyncManager.createInstance(this); 
           CookieSyncManager.getInstance().startSync();

           WebView myWebView = ((WebView)findViewById(R.id.webview));
           myWebView.setWebViewClient(new WebViewClient());
    }
   @Override
    protected void onResume() {
           super.onResume();
           CookieSyncManager.getInstance().stopSync();
    }
    @Override
     protected void onPause() {
           super.onPause();
           CookieSyncManager.getInstance().sync();
    }
}
