add android launcher shortcut to home screen

Question

This person was generous enough to add his code to his question. But I can't make out where to get the following variables:

res, app_id, and p in

BitmapDrawable bd = (BitmapDrawable) (res.get(app_id).activityInfo.loadIcon(p).getCurrent());

Here is his code:

Intent shortcutIntent = new Intent();
shortcutIntent.setClassName(ai.packageName, ai.name);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
shortcutIntent.addCategory(Intent.ACTION_PICK_ACTIVITY);
Intent intent = new Intent();
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, appName);

BitmapDrawable bd=(BitmapDrawable)(res.get(app_id).activityInfo.loadIcon(p).getCurrent());
Bitmap newbit;
newbit=bd.getBitmap();
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, newbit);

intent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
context.sendBroadcast(intent);

Also, are there anything that I must add to the manifest file?

EDIT:

I replace

BitmapDrawable bd=(BitmapDrawable)(res.get(app_id).activityInfo.loadIcon(p).getCurrent());
Bitmap newbit;
newbit=bd.getBitmap();
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON, newbit);

with

intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
        Intent.ShortcutIconResource.fromContext(this, R.drawable.launcher_icon));

and it still does not work. Which is why I am wondering about the manifest file.

Answer 1

In the manifest you need

<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
