Develop Reference

start method only after checking is there a needed value in sharedPref

Theres edit text field. It has to work like this:
1) if it is empty - nothing happen
2) if user put some NEW text starts method of TextWatcher with HTTP request which takes JSON object. Also the value of String will put in sharedpreference
3) if user open activity when sharedpreference already have value of previous string it has to just set text from that string and don't start method of TextWatcher with HTTP request.
So there are three conditions and progrmm has to make request only in case when value of string is not tha same as in shared pref. Now it sends request even if person just open app. I want to avoid wrong requests and make request only after new value of string.
THE MAIN QUESTION: How to launch HTTP request code ONLY in case if value in textfield is not the same as in sharedpref?
P.S. If you think my question is bad. Please tell me in notes NOT JUST MAKE -1 please. Teach new programmers

How to display extracted data from Facebook in a textview

I wrote code for connecting with Facebook and extracting username,email ID and Profile link .All the extracted details displays in different activity on the click of a button.But I wanted it to display it in the same actiivty as soon the login process is completed successfully.which means I need to edit the code after onSuccess but I don't no how to get the code
public class MainActivity extends AppCompatActivity {
CallbackManager callbackManager;
Button share,details;

To be Clear: All i wanted is to display the extracted details in the same activity after a successful login can you please help with it.?

please check the following code
protected void connectToFacebook() {

if (response.getError() != null) {
System.out.println("ERROR");
} else {
System.out.println("Success");
String jsonresult = String.valueOf(json);
System.out.println("JSON Result" + jsonresult);
String fbUserId = json.optString("id");

}
Log.v("FaceBook Response :", response.toString());
}
});
Bundle parameters = new Bundle();

Helo guys,
I'm new at android programming, I'm trying to make login application connect to localhost mysql with android studio based on this web. Here is code:
Mainactivity.java
public class Mainmenu extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainmenu);
Button login=(Button)findViewById(R.id.login);
login.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent login=new Intent(v.getContext(),Login.class);
startActivity(login);
}
});
Button register=(Button)findViewById(R.id.register);
register.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent regis= new Intent(v.getContext(),Register.class);
startActivity(regis);
}
});
Button exit=(Button)findViewById(R.id.exit);
exit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
finish();
}
});
}
Login.java
public class Login extends ActionBarActivity {
final EditText id=(EditText)findViewById(R.id.handphone);
final EditText pass=(EditText)findViewById(R.id.pass_login);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
TextView login=(TextView)findViewById(R.id.textView);
login.setText("Login to Human Tracker");
Button log=(Button)findViewById(R.id.login);
log.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String password=pass.getText().toString();
String handphone=id.getText().toString();
if (!password.equals("") && !handphone.equals("")) {
Toast.makeText(getApplication(),"Your id or password is wrong",Toast.LENGTH_SHORT).show();
} else {
masuk();
Toast.makeText(getApplication(),"Welcome", Toast.LENGTH_SHORT).show();
Intent user = new Intent(v.getContext(), User.class);
startActivity(user);
}
}
});
}
private void masuk(){
SharedPreferences prefs;
String prefName ="report";
InputStream is=null;
String result=null;
String line=null;
JSONObject jArray= null;
ArrayList<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
nameValuePairs.add(new BasicNameValuePair("hp",id.getText().toString()));
try {
HttpClient httpclient=new DefaultHttpClient();
HttpPost httppost=new HttpPost("http://10.0.0.2");
httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));
HttpResponse response = httpclient.execute(httppost);
HttpEntity entity=response.getEntity();
is=entity.getContent();
} catch (Exception e){
Log.e("Fail 1: Error in HTTP connection",e.toString());
Toast.makeText(getApplicationContext(),"Fail 1: Error in HTTP connection",Toast.LENGTH_SHORT).show();
}
try {
BufferedReader reader = new BufferedReader(new InputStreamReader(
is, "iso-8859-1"), 8);
StringBuilder sb = new StringBuilder();
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
result = sb.toString();
} catch (Exception e) {
Log.e("Fail 2: Error converting result ", e.toString());
}
try
{
JSONObject jobject = new JSONObject(result);
String S_pwd = jobject.getString("pass");
String S_name = jobject.getString("name");
String S_id = jobject.getString("id");
if(S_pwd.equals(pass.getText().toString())) {
Toast.makeText(getBaseContext(), "Login Successfully",
Toast.LENGTH_SHORT).show();
prefs = getSharedPreferences(prefName, MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
//---save the values in the EditText view to preferences---
editor.putString("id", S_id);
editor.putString("name", S_name);
//---saves the values---
editor.commit();
Toast.makeText(getApplicationContext(),"Login success",Toast.LENGTH_SHORT).show();
}
else {
Toast.makeText(getBaseContext(), "Login Failure \n" +
"\n Try Again", Toast.LENGTH_LONG).show();
id.setText("");
pass.setText("");
}
}
catch(Exception e)
{
Log.e("Fail 3", e.toString());
}
}
Everything is okay, i can go to User.java before add that private void masuk. Then im debug my application and no error. But why when i press login button on main menu(to go Login.java) it say 'Unfortunately Login has stopped'?

this will not work:
public class Login extends ActionBarActivity {
final EditText id=(EditText)findViewById(R.id.handphone);
final EditText pass=(EditText)findViewById(R.id.pass_login);
first of all call setContentView.
After that assign the Gui elements:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
EditText id=(EditText)findViewById(R.id.handphone);
EditText pass=(EditText)findViewById(R.id.pass_login);
or if you need them as class members:
EditText id;
EditText pass;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
id=(EditText)findViewById(R.id.handphone);
pass=(EditText)findViewById(R.id.pass_login);

it doesnt look like you ever log them in. look here
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
String email = inputEmail.getText().toString();
String password = inputPassword.getText().toString();
// Check for empty data in the form
if (email.trim().length() > 0 && password.trim().length() > 0) {
// login user
checkLogin(email, password);
} else {
// Prompt user to enter credentials
Toast.makeText(getApplicationContext(),
"Please enter the credentials!", Toast.LENGTH_LONG)
.show();
}
}
});
what is checkLogin(email, password);
and if it is returning a boolean you should be saying
if(checkLogin){
//log them in
}
can you post the checklogin code?

Remove notification from status bar after 20 second in android?

I created an android application. In this application I use the push notification concept. The notification is sent and received properly on the receiver.
Now I want to display the notification on status bar only for 20 second after that it will disappear. Can anyone tell me how can I do this? This is what I´ve so far.

you can create a service that runs in the background and that will timeout after 20 minutes and delete your notification.Before that a notification should be there to notify the user... and the user should be able to dismiss it on their own.
Reference :
Make notification disappear after 5 minutes
