  1. POvariable scope with inner classes
    text
    copied!<p>I am creating a <code>Splash</code> screen(<code>Activity</code>) in my Android app. I have an inner class which extends <code>AsyncTask</code>. The constructor for this inner class accepts a <code>Context</code> object, which is being sent inside the <code>Splash</code> activity's <code>onCreate</code> method. There is also reference to a constant <code>String</code> field. </p> <pre><code>public class Splash extends Activity { private static final String TAG = "Splash"; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.splash); new SplashAsyncTask(this).execute(new Void[] {}); } private class SplashAsyncTask extends AsyncTask&lt;Void, Void, Void&gt; { private Context context; public SplashAsyncTask(Context context) { this.context = context; } @Override protected Void doInBackground(Void... params) { try { Thread.sleep(1500); } catch(InterruptedException e) { if(Constants.LOGGING) Log.e(TAG, e.toString()); } return null; } @Override protected void onPostExecute(Void result) { super.onPostExecute(result); } } } </code></pre> <p>what scope should i be using for the <code>private static final String TAG = "Splash";</code> variable? all scopes seem to work fine, but what is proper/more efficient? I notice that eclipse automatically creates the variable with the <code>public</code> scope declaration</p> <p>Also, Do i really need to send the <code>Context</code> object to the <code>SplashAsyncTask</code> constructor? or can i/should i just use <code>Splash.this</code> in all cases where i need a <code>Context</code> reference?</p>
