This is a blog on how to make your own app launcher!
CODE FOR LAUNCHER:Intent startupIntent = new Intent(Intent.ACTION_MAIN);
startupIntent.addCategory(Intent.CATEGORY_LAUNCHER);
final android.content.pm.PackageManager pm = getPackageManager();
List<android.content.pm.ResolveInfo> activities = pm.queryIntentActivities(startupIntent,0);
Collections.sort(activities, new Comparator<android.content.pm.ResolveInfo>() {
public int compare(android.content.pm.ResolveInfo a, android.content.pm.ResolveInfo b) {
android.content.pm.PackageManager pm = getPackageManager();
return String.CASE_INSENSITIVE_ORDER.compare(a.loadLabel(pm).toString(), b.loadLabel(pm).toString());
}
});
ArrayAdapter<android.content.pm.ResolveInfo> adapter = new ArrayAdapter<android.content.pm.ResolveInfo>(this, android.R.layout.simple_list_item_1, activities) {
public View getView(int pos, View convertView, ViewGroup parent) {
TextView tv = new TextView(MainActivity.this);
android.content.pm.ResolveInfo ri = getItem(pos);
tv.setText(ri.loadLabel(pm));
LinearLayout lin = new LinearLayout(MainActivity.this);
ImageView iv = new ImageView(MainActivity.this);
iv.setImageDrawable(ri.loadIcon(pm));
lin.addView(iv);
lin.addView(tv);
tv.setGravity(Gravity.CENTER_VERTICAL);
tv.setPadding(16,0,0,0);
tv.setTextSize(16);
tv.setLayoutParams(new LinearLayout.LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT));
LinearLayout.LayoutParams p = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.MATCH_PARENT);
p.width = 70;
p.height = 70;
p.bottomMargin = 4;
p.topMargin = 4;
iv.setLayoutParams(p);
lin.setPadding(6,6,6,6);
return lin;
}
};
listview1.setAdapter(adapter);
listview1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView adapter, View v, int position, long id) {
android.content.pm.ResolveInfo resolveInfo = (android.content.pm.ResolveInfo)adapter.getItemAtPosition(position);
android.content.pm.ActivityInfo activityInfo = resolveInfo.activityInfo;
if (activityInfo == null) return;
Intent i = new Intent(Intent.ACTION_MAIN);
i.setClassName(activityInfo.applicationInfo.packageName, activityInfo.name);
startActivity(i);
}
});

But you must have listview and must be on MainActivity and the id of the list view must be listview1.
