Manifest.xml添加權限：
<uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.UNINSTALL_SHORTCUT" />
<uses-permission android:name="com.android.launcher.permission.READ_SETTINGS" />
代碼使用示例：
WowUtils.createShortcut(this, MainActivity.class, getString(R.string.app_name), R.drawable.ic_launcher);
