The project itself does not report any error, but when I run my project with the emulator, it popped up "Unfortunately project has stopped", can anyone look at my project and know what error is? There are three java classes and three xml files: 1. MainActivity.java 2. CustomListAdapter.java 3. MyBgTask.java 4. listView.xml 5. activity_main.xml
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyBgTask asyncTask = new MyBgTask();
CustomListAdapter adapter = new CustomListAdapter(this, asyncTask.getTimeArray(), asyncTask.getConditionArray(),
asyncTask.getTempArray(), asyncTask.getHumidityArray(), asyncTask.getUrls());
ListView list = (ListView) findViewById(R.id.listView);
list.setAdapter(adapter);
asyncTask.execute();
}
/*public void onListItemClick(ListView lv, View view, int position, int imgid) {
String Slecteditem= (String)getListAdapter().getItem(position);
Toast.makeText(this, Slecteditem, Toast.LENGTH_SHORT).show();
}*/

public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
