Application launcher icon is not deleted from Home screen when uninstalling android app

Question

I'm using a similar codesnippet as shown below to add an application shortcut on the homescreen:

    Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
    shortcutIntent.setClassName(this, this.getClass().getName());
    shortcutIntent.putExtra(EXTRA_KEY, "ApiDemos Provided This Shortcut");

    // Then, set up the container intent (the response to the caller)

    Intent intent = new Intent();
    intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
    intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.shortcut_name));
    Parcelable iconResource = Intent.ShortcutIconResource.fromContext(
            this,  R.drawable.app_sample_code);
    intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);

    // Now, return the result to the launcher

    setResult(RESULT_OK, intent);

There is no problem with creating the shortcut, but when uninstalling the app, the shortcut remains on the homescreen. When uninstalling other apps they all seem to also remove their corresponding homescreen shortcuts. This is what i try to achieve with my "created-by-code-shortcut-icon"

Does any of you Android experts here on Stackoverflow know whats needed to remove the app shortcut from the homescreen when the app is uninstalled ?

I found some related threads, but they do not provide me the solution for my problem, but please feel free to catch up:

Answer 1

I think you can try putting this action in the second Intent: "com.android.launcher.action.INSTALL_SHORTCUT"

This works for me, the launcher icon gets installed on the home screen, and when I uninstall the application, the icon is removed. Have been struggling some time with this.

Intent shortcutIntent = new Intent(Intent.ACTION_MAIN);
shortcutIntent.setClassName(this, this.getClass().getName());

Intent intent = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");
intent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
intent.putExtra(Intent.EXTRA_SHORTCUT_NAME, getString(R.string.app_name));
Parcelable iconResource = Intent.ShortcutIconResource.fromContext(
            this,  R.drawable.launcher_icon);
intent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);
sendBroadcast(intent);

Hope this helps.
