Android應用程序創建桌面快捷方式

創建快捷方式代碼：
public static final String READ_SETTINGS_PERMISSION = "com.Android.launcher.permission.READ_SETTINGS";
public static final String INSTALL_SHORTCUT_PERMISSION = "com.android.launcher.action.INSTALL_SHORTCUT";
private static final String TAG = "WowUtils";

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);
