Change this:

System.out.println("response msg==" + resp_msg);
Toast.makeText(Registration.this, "response msg==" + resp_msg, Toast.LENGTH_SHORT).show();
}
To:
if (resp_code.equals("200")) {
System.out.println("response msg==" + resp_msg);
Toast.makeText(Registration.this, "response msg==" + resp_msg, Toast.LENGTH_SHORT).show();
} else {
Toast.makeText(Registration.this,"Donot Match",Toast.LENGTH_SHORT).show();
}

call compare_version() method in else condition

First you have to understand the different between the login success response and the login failed(on a wrong username password combination) response.
You are reading "res_response" value from your JSON response although it is not in your login failed response.
Also you did a mistake in your code by hard-coding resp_code = "200";

How to use SharedPreferences in Android to store, fetch and edit values [closed]

Closed 5 years ago.
hey guys so i got a login activity that checks username and password with server to authenticate users. i want to use sharedpermissions to store username and password so that the user wont have log in every time. i also want to create a login button.
i tried to implement it but itjust skips login acitivity and takes me to my second activity. i left some of sharedpermission codes as comments (//)
can anyone show/tell me the best i can do it?
public class LoginActivity extends AppCompatActivity {
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
//String username = "";
//String password = "";
//SharedPreferences pre;

LoginActivity.this.startActivity(registerIntent);
}
final String username1 = SharedPreferenceUtils.getUsername(this);
final String password1 = SharedPreferenceUtils.getPassword(this);
// pre = getSharedPreferences("pref",MODE_PRIVATE);
//if(pre.getBoolean("username",true) && pre.getBoolean("password",true)){
tvRegisterLink.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent registerIntent = new Intent(LoginActivity.this, RegisterActivity.class);
LoginActivity.this.startActivity(registerIntent);
}
});
bLogin.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
final String username = etUsername.getText().toString();
final String password = etPassword.getText().toString();
// Response received from the server
Response.Listener<String> responseListener = new Response.Listener<String>() {

intent.putExtra("name", name);
intent.putExtra("username", username);
LoginActivity.this.startActivity(intent);
} else {
AlertDialog.Builder builder = new AlertDialog.Builder(LoginActivity.this);
builder.setMessage("Login Failed")
.setNegativeButton("Retry", null)
.create()
.show();
}
} catch (JSONException e) {
e.printStackTrace();
}
}
};
LoginRequest loginRequest = new LoginRequest(username, password, responseListener);
RequestQueue queue = Volley.newRequestQueue(LoginActivity.this);
queue.add(loginRequest);
}
});
}
}
public class UserAreaActivity extends AppCompatActivity {

final TextView etuname = (TextView) findViewById(R.id.textView3);
final Button Logout = (Button) findViewById(R.id.logout);
//String Name = SharedPreferenceUtils.getName(this);
//etwelcome.setText(Name);
red.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent registerIntent = new Intent(UserAreaActivity.this, Report.class);
UserAreaActivity.this.startActivity(registerIntent);
}
});
messages.setOnClickListener(new View.OnClickListener() {
#Override

if(isClear){

UserAreaActivity.this.startActivity(registerIntent);
}
}
});
Intent intent = getIntent();
String name = intent.getStringExtra("name");
String username = intent.getStringExtra("username");
String message = "Welcome " + name;
etwelcome.setText(message);
etusername.setText(username);
//Intent in = new Intent(getApplicationContext(), Messages.class);
//in.putExtra("username", username);
//UserAreaActivity.this.startActivity(in);
}
}

You can use SharedPreferences in your code .
Try this .
public class SharedPreferenceUtils {
private static final String SP_NAME = "sp";
public static final String USERNAME = "username";
public static final String PASSWORD = "password";
// create
public static boolean createSP(Context context, String username, String password) {
SharedPreferences.Editor editor = context.getSharedPreferences(SP_NAME, Context.MODE_PRIVATE).edit();
editor.putString(USERNAME, username);
editor.putString(PASSWORD, password);
return editor.commit();
}
// clear
public static boolean clearSP(Context context) {
SharedPreferences sharedPreferences = context.getSharedPreferences(SP_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPreferences.edit();
return editor.clear().commit();
}
// get access info
public static String getUsername(Context context) {
SharedPreferences sp = context.getSharedPreferences(SP_NAME, Context.MODE_PRIVATE);
return sp.getString(USERNAME, "");
}
// get branch info
public static String getPassword(Context context) {
SharedPreferences sp = context.getSharedPreferences(SP_NAME, Context.MODE_PRIVATE);
return sp.getString(PASSWORD, "");
}
}
Use in LoginActivity
SharedPreferenceUtils.createSP(this,username,password);
And use in other Activity
String username = SharedPreferenceUtils.getUsername(this);
String password = SharedPreferenceUtils.getPassword(this);
Edit
if (success) {
String name = jsonResponse.getString("name");
SharedPreferenceUtils.createSP(this, username, password);
}
Edit
private EditText etUsername, etPassword;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etUsername = (EditText) findViewById(R.id.etUsername);
etPassword = (EditText) findViewById(R.id.etPassword);
String username = SharedPreferenceUtils.getUsername(this);
String password = SharedPreferenceUtils.getPassword(this);
etUsername.setText(username);
etPassword.setText(password);
}
Edit
if(TextUtils.isEmpty(etUsername.getText().toString())||TextUtils.isEmpty(etPassword.getText().toString())){
Intent intent = new Intent(LoginActivity.this, A.class);
LoginActivity.this.startActivity(intent);
} else {
Intent registerIntent = new Intent(LoginActivity.this, B.class);
LoginActivity.this.startActivity(intent);
}
Edit
boolean isClear = SharedPreferenceUtils.clearSP(UserAreaActivity.this);
if(isClear){
Intent registerIntent = new Intent(UserAreaActivity.this, LoginActivity.class);
UserAreaActivity.this.startActivity(registerIntent);
}

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 {

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_mainmenu);

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);

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";

httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

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();
}

"\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?

Intent not passes my to my second Activity

The reason is that ones i fill in my user name, and password and click login button it is loads again at page requires tu fill user name, and password here is my source code
public class MainActivity extends Activity {
private EditText mTextUserName;
private EditText mTextPassword;
public String user_name;
public String pass_word;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextUserName = (EditText) findViewById(R.id.textUserName);
mTextPassword = (EditText) findViewById(R.id.textPassword);
final Button mButtonLogin = (Button) findViewById(R.id.buttonLogin);
mButtonLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
user_name = mTextUserName.getText().toString();
pass_word = mTextPassword.getText().toString();
// i am passing this intent
Intent goToNextActivity = new Intent(getApplicationContext(), ViewActivity.class);
goToNextActivity.putExtra("username", user_name);
goToNextActivity.putExtra("password", pass_word);
startActivity(goToNextActivity);
}
});
}
and in mine ViewActivity also
public class ViewActivity extends Activity {
private WebView webView;
public String pass_word;
public String user_name;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.view);
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollbarFadingEnabled(false);
webView.getSettings().setDefaultFontSize(20);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
//here i get them
getIntent().getStringExtra("username");
getIntent().getStringExtra("password");
webView.loadUrl("http://intranet.mdis.uz/");
}
but this doest works(( i spended 8 hours on research but nothing helped me

I think this line is wrong:
Intent goToNextActivity = new Intent(getApplicationContext(), ViewActivity.class);
you should not use ApplicationContext when you trying to start new activity. Try this:
Intent goToNextActivity = new Intent(MainActivity.this, ViewActivity.class);
EDIT:
Try this, it should send data via POST:
webView = (WebView) findViewById(R.id.webView);
webView.getSettings().setUseWideViewPort(true);
webView.setScrollbarFadingEnabled(false);
webView.getSettings().setDefaultFontSize(20);
webView.getSettings().setBuiltInZoomControls(true);
webView.getSettings().setJavaScriptEnabled(true);
webView.setWebViewClient(new WebViewClient());
String username = getIntent().getStringExtra("username");
String password = getIntent().getStringExtra("password");
String data = "username=" + username + "&password=" + password;
webView.postUrl("http://intranet.mdis.uz/", EncodingUtils.getBytes(data, "base64"));

Let me try it.
Do the modification like this once and see plz...
public class MainActivity extends Activity {
private EditText mTextUserName;
private EditText mTextPassword;
public String user_name;
public String pass_word;
ConnectionClass cc;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mTextUserName = (EditText) findViewById(R.id.textUserName);
mTextPassword = (EditText) findViewById(R.id.textPassword);
cc=new ConnectionClass(this);
final Button mButtonLogin = (Button) findViewById(R.id.buttonLogin);
mButtonLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
user_name = mTextUserName.getText().toString();
pass_word = mTextPassword.getText().toString();
user_name=Uri.encode(user_name); // you can encode your parameters so that it does not throw exception for e.g it will replace a space as %20 otherwise if user enters special character error will come.. :)
pass_word=Uri.encode(pass_word); // same as above
String url="http://myserver.com/login.php?username="+user_name"&password="+user_name; // this is your server page url and passing username and password in plain url u can test it in browser to verify its working :)
new AsyncTask<String,Void,String>() // new android versions does not allow network operations on main thread but need to do asynchronously...
{
#Override
protected String doInBackground(String... params) {
return cc.getServerResponse(params[0]);
}
#Override
protected void onPostExecute(String result) { // this method runs on UI thread and is called when background process is done to make it more fancy u can use onPreExecute() to show a loader and dismiss the dialog here :)
super.onPostExecute(result);
if(result!=null)
{
if(result.equals("1") // assuming u r returning "1" if successful.
{
Toast.makeText(context, "Successful", 2000).show();
Intent goToNextActivity = new Intent(MainActivity.this, ViewActivity.class);
goToNextActivity.putExtra("username", user_name);
goToNextActivity.putExtra("password", pass_word);
startActivity(goToNextActivity);
}
}
else
Toast.makeText(context, "Network problem...", 2000).show();
}
}.execute(url);
}
}
});
}
Here is the ConnectionClass
public class ConnectionClass {
Context context;
public ConnectionClass(Context ctx) {
this.context=ctx;
}
public String getServerResponse(String urlLink)
{
try
{
HttpClient client = new DefaultHttpClient();
HttpPost http_get = new HttpPost(url);
HttpResponse responses;
responses = client.execute(http_get);
if (responses != null)
{
InputStream in = responses.getEntity().getContent();
String a = convertStreamToString(in);
// Log.i("RETURN",a+"");
return a;
}
}
catch (Exception e)
{
e.printStackTrace();
}
return null;
}
String convertStreamToString(InputStream is) {
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try
{
while ((line = reader.readLine()) != null)
{
sb.append(line);
}
}
catch (Exception e)
{
//Toast.makeText(context, e.toString()+" io2", Toast.LENGTH_LONG).show();
}
finally
{
try
{
is.close();
}
catch (Exception e)
{
//Toast.makeText(context, e.toString()+" io3", Toast.LENGTH_LONG).show();
}
}
return sb.toString();
}
}
Hope it helps u :)
Thx
