[ASK] Penggunaan Text Watcher Message Handler

Salam agan-agan master
ane lagi buat aplikasi pake Message Handler sama Text Watcher,
Jadi si message handler ane pake buat ngambil data dari soket tcp arduino
terus text watcher buat ngeliat kalo editText terisi 10 karakter dia akan search database. Berikut masing-masing kodenya

Spoiler for code watchere:

Code:



// EditTextWacther Implementation

 private final TextWatcher mTextEditorWatcher = new TextWatcher() {

 

 public void beforeTextChanged(CharSequence s, int start, int count, int after)

 {

 // When No ID

 }



 public void onTextChanged(CharSequence s, int start, int before, int count)

 {

 

 }



 @Override

 public void afterTextChanged(Editable s) {

 // TODO Auto-generated method stub

 if(s.length()==10)

 {

 //sapi cariSapi = new sapi();

 EditText etTag = (EditText) findViewById(R.id.editText1);

 EditText etWaktu = (EditText) findViewById(R.id.editText2);

 EditText etStatus = (EditText) findViewById(R.id.editText3);

 cari=etStatus.getText().toString();

 Cursor cursor=dataSource.cariDataSapi(cari);

 if(cursor.moveToFirst()){

 hasildb=cursor.getString(2);

 for (; !cursor.isAfterLast(); cursor.moveToNext()) {

 hasildb = cursor.getString(2);

 idhasil = cursor.getString(1);

 dbid = cursor.getLong(0);

 cariSapi.setId(cursor.getLong(0));

 cariSapi.setTag(cursor.getString(1));

 cariSapi.setWaktu(cursor.getString(2));

 }

 }

 etTag.setText(idhasil);

 etWaktu.setText(hasildb);

 //etStatus.setText(count);

 } 



 }

};

Spoiler for handler:

Code:



@SuppressLint("HandlerLeak") Handler myUpdateHandler = new Handler() {

 public void handleMessage(Message msg) {

 switch (msg.what) {

 case MSG_ID:

 EditText etStatus = (EditText) findViewById(R.id.editText3);

 etStatus.setText(mClientMsg);

 break;

 default:

 break;

 }

 super.handleMessage(msg);

 }

 };

 

 class CommsThread implements Runnable {

 public void run() {

 Socket s = null;

 try {

 ss = new ServerSocket(SERVERPORT );

 } catch (IOException e) {

 e.printStackTrace();

 }

 while (!Thread.currentThread().isInterrupted()) {

 Message m = new Message();

 m.what = MSG_ID;

 try {

 if (s == null)

 s = ss.accept();

 BufferedReader input = new BufferedReader(new InputStreamReader(s.getInputStream()));

 String st = null;

 st = input.readLine();

 mClientMsg = st;

 myUpdateHandler.sendMessage(m);

 } catch (IOException e) {

 e.printStackTrace();

 }

 }

 }

 }

}

yang bikin ane bingung adalah ketika aplikasi menerima karakter dari soket tcp, aplikasi langsung forced close. emoticon-Sorry

Ada apa ya gan?ane liat di stackoverflow.com katanya pake background system nah bagaimana cara implementasi di kode ane jika kondisi kode ane seperti ini?

Trims banget ya gan kalo ada yang bantu?
