  1. POMy Simple ListView app is leaking memory. What am I doing wrong?‏
    text
    copied!<p>First off, I did post this to the android google group first but its moderated and I'm not sure how long itll take to show up there so hoping someone here can help.</p> <p>I created a simple app with a ListView following the ListActivity examples I found on the net.</p> <p>The app has 2 activities with the first having a button to create the second. When i hit the close button on the second activity I would like it to release its memory (or at least allow it to be garbage collected). Currently it will never release.</p> <p>I must be doing something wrong here because the MyListActivity never gets released. Can anyone tell me if I am doing something wrong with the way my activities are created/destroyed? or if my usage of the ListView is wrong?</p> <p>Thanks.</p> <p>My App as a zip - <a href="http://www.mediafire.com/?l26o5hz2bmbwk6j" rel="nofollow">http://www.mediafire.com/?l26o5hz2bmbwk6j</a></p> <p>Screen Shot of Eclipse MAT showing the list activity never releasing memory - www.mediafire.com/?qr6ga0k</p> <pre><code>public class MyListActivity extends ListActivity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.listlayout); ListAdapter ada = new ArrayAdapter&lt;String&gt;(this,android.R.layout.simple_list_item_1, GENRES); setListAdapter(ada); } @Override public void onDestroy() { super.onDestroy(); System.gc(); } public void ClickHandler(View target) { switch (target.getId()) { case R.id.LL_Btn1: finish(); break; } } private static final String[] GENRES = new String[] { "Action", "Adventure", "Animation", "Children", "Comedy", "Documentary", "Drama", "Foreign", "History", "Independent", "Romance", "Sci-Fi", "Television", "Thriller" };} public class MainActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } public void ClickHandler(View target) { switch (target.getId()) { case R.id.M_Button01: Intent intent = new Intent(); intent.setClassName(MyListActivity.class.getPackage().getName(), MyListActivity.class.getName()); startActivity(intent); break; } }} </code></pre>
