홈화면에 아이콘 추가하기. ㅋㄷ

AndroidManifest.xml 파일에 권한 추가.

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

실행화면에 코드 추가.

Intent shortcutIntent = new Intent();
shortcutIntent.setClassName("packageName", "className");
//shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

Intent addIntent = new Intent();
addIntent.putExtra(Intent.EXTRA_SHORTCUT_INTENT, shortcutIntent);
addIntent.putExtra(Intent.EXTRA_SHORTCUT_NAME, "shortcut_name");
addIntent.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE,
Intent.ShortcutIconResource.fromContext(context, R.drawable.icon));
//intent.putExtra("duplicate", false);
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
            context.sendBroadcast(addIntent);
