?PS:关于删除

网上有人说shortcut的删除需要root。其实是不用的。

只是在删除的时候有点和创建不同的地方，看代码：

?

AndroidShortCutUtils.addShortcutToDesktop(this, this.getPackageName(), ".MainActivity", null, null, false);//删除的时候className需要包括有package的信息。AndroidShortCutUtils.delShortcutFromDesktop(this,  this.getPackageName(), "com.knowhow.android.client.MainActivity", null);
