Note: If the <data android:scheme= "Itheima" ></DATA> is configured in the manifest file, then the intent must be activated with Intent.setdata (Uri.parse ("Itheima: xxx ")); Such a setting, otherwise error.
If the manifest file is configured as <data android:scheme= "Itheima" android:mimetype= "Vns.android.cursor.item/haha" ></data> The activation intent must have Intent.setdataandtype (Uri.parse ("Itheima:gogogo"), "Vns.android.cursor.item/haha") or an error.
Scheme is the meaning of the specification of the data, and MimeType is the type of the description data
