Rt, write the code as follows

 public static void writeTag (Tag Tag) {
MifareUltralight ultralight=MifareUltralight. Get (tag); 
Try {
Ultralight. The connect (); 
Ultralight. WritePage (4, "1". GetBytes (Charset. Class.forname (" utf-8 "))); 
//ultralight. WritePage (5, "efgh" getBytes (Charset. Class.forname (" US - the ASCII "))); 
//ultralight. WritePage (6, "ijkl" getBytes (Charset. Class.forname (" US - the ASCII "))); 
//ultralight. WritePage (7, "mnop" getBytes (Charset. Class.forname (" US - the ASCII "))); 
Ultralight. Close (); 
} the catch (IOException e) {
The e (" NFC WRITE ERROR ", "IOException while closing MifareUltralight... ", e); 
} the finally {
Try {
Ultralight. Close (); 
} the catch (IOException e) {
The e (" NFC WRITE ERROR ", "IOException while closing MifareUltralight... ", e); 
} 
} 
} 

But one of the following implementation will generate abnormal:
