    <p>I am trying to write a very simple app that displays the name of every installed app on the device in a listview. I am using Google's ListView tutorial as a base.</p> <p>Here is my code:</p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final PackageManager pm = this.getPackageManager(); Intent intent = new Intent(Intent.ACTION_MAIN, null); intent.addCategory(Intent.CATEGORY_LAUNCHER); final ArrayList&lt;ResolveInfo&gt; list = (ArrayList&lt;ResolveInfo&gt;) pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED); for (ResolveInfo rInfo : list) { Log.i(TAG, ": Installed Applications " + rInfo.activityInfo. applicationInfo.loadLabel(pm).toString()); } final ArrayAdapter&lt;ResolveInfo&gt; adapter = new ArrayAdapter&lt;ResolveInfo&gt;(this, R.layout.list_item, list) { @Override public View getView(int position, View convertView, ViewGroup parent) { if (convertView == null) convertView = LayoutInflater.from(parent.getContext()). inflate(R.layout.list_item, parent, false); final String text = list.get(position).activityInfo. applicationInfo.loadLabel(pm).toString(); ((TextView)convertView.findViewById(R.id.text)).setText(text); final Drawable drawable = list.get(position).activityInfo.applicationInfo.loadIcon(pm); ((ImageView)convertView.findViewById(R.id.image)).setImageDrawable(drawable); return convertView; } }; setListAdapter(adapter); ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) { // On Item Click Activity // This is where I want to send the Package Name of the app selected to be passed to a method. } }); } &lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;ImageView android:id="@+id/image" android:layout_width="50dp" android:layout_height="50dp" /&gt; &lt;TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" android:padding="10dp" android:textSize="16sp" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>UPDATE: I now need to use an OnItemClickListener to pass the Package Name of the App selected to a method.</p>

    1. COCheck your LogCat to find what exception is being raised. Post it here if that doesn't answer the question.

    3. COIt turns out that this only force closes in the emulator, works okay on an actual device. Unfortunately the package info displays like this: ResolveInfo{4053e448 com.alphonso.pulse.NewsRack p=0 o=0 m=0x108000} Any ideas on how to make this more human read-able?

Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
