@Override

public void onClick(View v) {

Cursor get = db.getAll();

get.moveToFirst();

if (get.getCount() == 0) {

db.insert(pass.getText().toString());

public boolean onOptionsItemSelected(MenuItem item) {

switch (item.getItemId()) {

case R.id.exit:

finish();

break;

}

return false;

}

}

5. Buat service ServiceRecv.java seperti dibawah ini:

import android.telephony.SmsMessage;

import android.widget.Toast;

public class ServiceRecv extends Service {

private class SMSReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

Bundle extras = intent.getExtras();

String strMessage = “”;

if (extras != null) {

Object[] smsextras = (Object[]) extras.get(“pdus”);

for (int i = 0; i < smsextras.length; i++) {

SmsMessage smsmsg = SmsMessage

.createFromPdu((byte[]) smsextras[i]);

String strMsgBody = smsmsg.getMessageBody().toString();

String strMsgSrc = smsmsg.getOriginatingAddress();

strMessage += “SMS from ” + strMsgSrc + ” : ” + strMsgBody;

}

Bundle send = new Bundle();

send.putString(“message”, strMessage);

Intent change = new Intent(ServiceRecv.this, Alert.class);

change.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

change.putExtras(send);

startActivity(change);

}

}

}

private SMSReceiver smsRecv;

private IntentFilter intentFilter;

@Override

public void onCreate() {

super.onCreate();

smsRecv = new SMSReceiver();

intentFilter = new IntentFilter();

intentFilter.addAction(“android.provider.Telephony.SMS_RECEIVED”);

registerReceiver(smsRecv, intentFilter);

}

@Override

public int onStartCommand(Intent intent, int flags, int startId) {

// TODO Auto-generated method stub

return Service.START_STICKY;

}

@Override

public void onDestroy() {

super.onDestroy();

unregisterReceiver(smsRecv);

}

@Override

public IBinder onBind(Intent intent) {

// TODO Auto-generated method stub

return null;

}

}

6. Buat kelas DatabaseHandler.java untuk menghandle database seperti dibawah ini:

package com.interactive.i_sms;

import android.content.ContentValues;

import android.content.Context;

import android.database.Cursor;

import android.database.sqlite.SQLiteDatabase;

import android.database.sqlite.SQLiteOpenHelper;

public class DatabaseHandler extends SQLiteOpenHelper {

private static final String DATABASE_NAME = “0001.db”;

private static final int SCHEMA_VERSION = 6;

public DatabaseHandler(Context context) {

super(context, DATABASE_NAME, null, SCHEMA_VERSION);

}

@Override

public void onCreate(SQLiteDatabase db) {

db.execSQL(“CREATE TABLE PASSWORD (ID INTEGER NOT NULL PRIMARY KEY AUTOINCREMENT, PASSWORD VARCHAR NOT NULL)”);

}

@Override

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {

// TODO Auto-generated method stub

}

public void insert(String password) {

ContentValues carry = new ContentValues();

carry.put(“PASSWORD”, password);

getWritableDatabase().insert(“PASSWORD”, null, carry);

}

public void update(String password) {

ContentValues carry = new ContentValues();

carry.put(“PASSWORD”, password);

getWritableDatabase().update(“PASSWORD”, carry, null, null);

}

public Cursor getAll() {

return (getReadableDatabase().rawQuery(“SELECT * FROM PASSWORD”, null));

}

public String getPassword(Cursor c) {

return (c.getString(1));

}

}

7. Buat tampilan halaman pengaturan prefs.xml seperti dibawah ini:

<?xml version=“1.0” encoding=“utf-8”?>

<PreferenceScreen

xmlns:android=“http://schemas.android.com/apk/res/android&#8221; >

<CheckBoxPreference

android:title=“Password Authentication”

android:summaryOn=“Password is enabled”

android:summaryOff=“Password is disabled”

android:defaultValue=“true”

android:key=“passEnabled” />

<EditTextPreference

android:title=“Setup new password”

android:summary=“input your new password”

android:key=“newPass” />

</PreferenceScreen>

8. Buat preference activity Prefs.java seperti dibawah ini:

package com.interactive.i_sms;

import android.content.SharedPreferences;

import android.database.Cursor;

import android.os.Bundle;

import android.preference.PreferenceActivity;

import android.preference.PreferenceManager;

public class Prefs extends PreferenceActivity{

private SharedPreferences pref;

DatabaseHandler db = new DatabaseHandler(this);

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

addPreferencesFromResource(R.xml.prefs);

pref = PreferenceManager.getDefaultSharedPreferences(getBaseContext());

}

@Override

protected void onDestroy() {

super.onDestroy();

String newPass = pref.getString(“newPass”, “”);

Cursor get = db.getAll();

get.moveToFirst();

if (!db.getPassword(get).equals(newPass)) {

if (!newPass.equals(“”)) {

db.update(newPass);

}

}

}

}

9. Buat tampilan main.xml seperti dibawah ini:

<?xml version=“1.0” encoding=“utf-8”?>

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_margin=“10dp” >

<TextView

android:id=“@+id/passT”

android:layout_width=“wrap_content”

android:layout_height=“wrap_content”

android:layout_alignParentLeft=“true”

android:layout_alignParentTop=“true”

android:text=“Password : “ />

<TextView

android:id=“@+id/tes”

android:layout_width=“wrap_content”

android:layout_height=“wrap_content”

android:layout_toRightOf=“@+id/passT” />

public class Main extends Activity {

private SharedPreferences pref;

private TextView tes;

private ImageView end;

private Intent smsReceiver;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

smsReceiver = new Intent(this, ServiceRecv.class);

startService(smsReceiver);

pref = PreferenceManager.getDefaultSharedPreferences(getBaseContext());;

tes = (TextView) findViewById(R.id.tes);

end = (ImageView) findViewById(R.id.end);

end.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

stopService(smsReceiver);

Toast.makeText(Main.this, “SMS popup service has been stopped”, Toast.LENGTH_LONG).show();

}

});

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

MenuInflater menuItem = getMenuInflater();

menuItem.inflate(R.menu.options_main, menu);

return true;
