[Java for Android App Development] Florent1510:
I am currently working on an App Switcher with the ability to also add custom apps in the app switcher. So, I already got the recent apps loader built. This is the code for this part of the app:

public class Corners_RecentApps extends Activity {
private ArrayList<PanelItemDetail> rowItems = null;
private ListView listView;
private ArrayList<String> packageName = null;
private ArrayList<String> className = null;

[MENTION=439709]override[/MENTION]
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
boolean rightpanel = getSharedPreferences(getPackageName() + "_preferences", Context.MODE_PRIVATE).getBoolean("panelpos_right", true);
if(rightpanel){
overridePendingTransition(R.anim.left_slide_in_fast, 0);
setContentView(R.layout.right_side_panel);
}
else
{
overridePendingTransition(R.anim.right_slide_in_fast, 0);
setContentView(R.layout.activity_left_side_panel);
}
ImageView imgbtn = (ImageView) findViewById(R.id.transparentbackground);
ImageView panelbg = (ImageView) findViewById(R.id.panelbackground);
listView = (ListView)findViewById(R.id.panelcontents);
packageName = new ArrayList<String>();
className = new ArrayList<String>();

ActivityManager am = (ActivityManager) this.getSystemService(ACTIVITY_SERVICE);
List<ActivityManager.RecentTaskInfo> tasks = am.getRecentTasks(30, 0);
rowItems = new ArrayList<PanelItemDetail>();
PackageManager pacMgr = getPackageManager();

for (ActivityManager.RecentTaskInfo recentTask : tasks) {
try {
rowItems.add(new PanelItemDetail(pacMgr.getApplicationIcon(recentTask.origActivity.getPackageName())));
packageName.add(recentTask.origActivity.getPackageName());
className.add(recentTask.origActivity.getClassName());

Log.d("#@#", "getPackageName = " + recentTask.origActivity.getPackageName());
Log.d("#@#", "getClassName = " + recentTask.origActivity.getClassName());
} catch (NameNotFoundException e) {
e.printStackTrace();
}
}

SharedPreferences myPreference = PreferenceManager.getDefaultSharedPreferences(this);
String itembg = myPreference.getString("itembg_list", "");

if(itembg.equals("defaults"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_default, rowItems);
listView.setAdapter(adapter);
}
else if(itembg.equals("dark"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_dark, rowItems);
listView.setAdapter(adapter);
}
else if(itembg.equals("light"))
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_light, rowItems);
listView.setAdapter(adapter);
}
else
{
PanelArrayAdapter adapter = new PanelArrayAdapter(this,R.layout.panelrow_none, rowItems);
listView.setAdapter(adapter);
}
listView.setOnItemClickListener(new OnItemClickListener() {
[MENTION=439709]override[/MENTION]
public void onItemClick(AdapterView<?> parent, View view, int postion, long id) {
try{
boolean rightpanel = getSharedPreferences(getPackageName() + "_preferences", Context.MODE_PRIVATE).getBoolean("panelpos_right", true);

Intent taskintent = getPackageManager().getLaunchIntentForPackage(packageName.get(postion).toString());
startActivity(taskintent);

if(rightpanel){
overridePendingTransition(R.anim.right_slide_in, R.anim.zoom_out);
}
else
{
overridePendingTransition(R.anim.left_slide_in, R.anim.zoom_out);
}
finish();
}

catch (NullPointerException fail) {
Toast.makeText(getApplicationContext(), "!", Toast.LENGTH_SHORT).show();
}

}
});
SharedPreferences panelbgpref = PreferenceManager.getDefaultSharedPreferences(this);
String panelbgset = panelbgpref.getString("panelbg_list", "");

if(panelbgset.equals("light"))
{
panelbg.setImageResource(R.drawable.panelbg_light);
}
else
{
panelbg.setImageResource(R.drawable.panelbg);
}

imgbtn.setOnClickListener(new View.OnClickListener(){
[MENTION=439709]override[/MENTION]
public void onClick(View v) {
if(v.getId() ==R.id.transparentbackground){
moveTaskToBack(true);
finish();
}
}
});
}

Now I want to let the users define in the app settings up to 3 own apps that should be shown on every moment.

How should I do that?

Thank you :)
