LoaderManager is being called automatically on pressing Back key in Android? - java

I am newbie in Android. Here is the LoaderManager class I have written code on Button click to initialize Loader. When I am pressing back button of device I came to previous activity and my call to Initialize loader is again called and it automatically starts new activity without pressing any key even my initialize loader is on button click.
Why is it happening so?
LoginActivityService.java
public class LoginActivityService extends Activity implements
LoaderCallbacks<User>
{Context context;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login_view_service);
context = this;
userName = (EditText) findViewById(R.id.userName1);
password = (EditText) findViewById(R.id.password1);
loginBtn = (ImageButton) findViewById(R.id.login1);
logoutBtn = (Button) findViewById(R.id.logout1);
loginBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
doLogin(userName.getText().toString(),password.getText().toString());
}
});
}
public void doLogin(String userNameString, String passwordString) {
Log.i("do login button if", "login button clicked" + "username:"
+ userNameString + "passwor:" + passwordString);
if (userNameString.length() == 0 || passwordString.length() == 0) {
Toast.makeText(context, "UserName Or Password Should be Filled",
Toast.LENGTH_SHORT).show();
}
else
{ try {
getLoaderManager().restartLoader(1, null,LoginActivityService.this);
}
catch (Exception e) {
Log.i("do Login Stack Trace if Response false","do Login Stack Trace Catch Block");
e.printStackTrace();
}}
#Override
public Loader<User> onCreateLoader(int id, Bundle args) {
Log.i("in loader", "login button clicked" + "username:"+ userName.getText().toString() + "passwor:"
+ password.getText().toString());
loginLoader = new LoginLoader(context, userName.getText().toString(),
password.getText().toString(), "2013-07-10 01:18:26");
Log.i("login loader", "" + loginLoader);
return loginLoader;
}
#Override
public void onLoadFinished(Loader<User> arg0, User userInstance) {
Log.i("status", "" + userInstance);
if (userInstance == null) {
Toast.makeText(getApplicationContext(),"User Id and Password is wrong", Toast.LENGTH_SHORT).show();
}
else {
Intent intent = new Intent(LoginActivityService.this,
ProposalListActivity.class);
startActivity(intent);
}
}
#Override
public void onLoaderReset(Loader<User> arg0) {
// TODO Auto-generated method stub
// getLoaderManager().restartLoader(10000,null,LoginActivityService.this);
}
}
My problem is I am getting data from Service and "userInstance" is not null so it moves towards nextActivity but when I press back key of device it comes to the previous activity and it automatically moves to the same activity from where we have pressed back key. This is happening because my class that extends AsyncTaskLoader have onloadinBackground() and this method is being called again can someone point me why this is happening:
public class LoginLoader extends AsyncTaskLoader<User>
{
#Override
public User loadInBackground() {
// TODO Auto-generated method stub
User listUser = LoginListService.getLoginInstance().getLoginResult(userName,password,apkVersion);
Log.d(TAG, "load in background");
return listUser;
}
}
Can someone please guide me what code I need to add in this to avoid automatic call of loadinBackground?

Try to destroy the loader once you received data:
public void onLoadFinished(Loader<User> arg0, User userInstance) {
Log.i("status", "" + userInstance);
if (userInstance == null) {
Toast.makeText(getApplicationContext(),"User Id and Password is wrong", Toast.LENGTH_SHORT).show();
} else {
getLoaderManager().destroyLoader(arg0.getId());
Intent intent = new Intent(LoginActivityService.this,
ProposalListActivity.class);
startActivity(intent);
}
}

i don't know where i put the sharedpreferces exactly to make it save the session
the sharedpreferences there just for passing data between Main.java and Menu.java
i wan't to add another sheredPreferences to save session like facebook means when i login in Main.java ---redirecte--> Menu.java so if i close an run the app again he will start with Menu.java :) and Thank you
if you implement that way the user will login only once in your application and will be forever connected. the best is to do it this way:
first add a checkbox to login to let the user decide if he wants to save his login.
add sharepreferences if checked and delete sharepreferences if uncheck.
read sharedpreferences in the onresume() method of main activity and add some logic to intent directly to menu activity if preferences is not null
I used mySharedPreferences that indicate to me if user already logged in, and I pass a int value from previous activity to know if the user just enter the app or not.
public class ConnectWithFaceBookActivity extends Activity{
int mode = Activity.MODE_PRIVATE;
private SharedPreferences mySharedPreferences;

you can simply use this
Intent intent = getIntent();
finish();
startActivity(intent);
I hope thats work
You can use sharedPreference for this. you can save the value of each edittext in one sharedprefrerece (with unique key for each edittext and set values at the time of focus change. see example:)
EditText txtEdit= (EditText) findViewById(R.id.edittxt);
txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {
public void onFocusChange(View v, boolean hasFocus) {
if(!hasFocus)
//do job here when Edittext lose focus
//means save value here
}
});
and load these saved value at on create.
Hope you are getting some idea from this
Edit: This is for your condition
if(firstRun==false)//if running for first time
{
SharedPreferences.Editor editor=settings.edit();
editor.putBoolean("firstRun",true);
editor.commit();
//execute your code for first time
}
else
{
if(alldataSaved==false)
{
//stay in this activiy
}
else
{
Intent iSubmit = new Intent(Registration_Form.this,Employee_List.class);
startActivity(iSubmit);
finish();
//Default Activity startActivity(a);
}
}
That's not how Android works. You cannot "restore" the same Activity in that fashion. What you CAN however do is save out the EditText content, for example in the onPause() or onStop() function, save out the contents of the EditTexts as Strings, put them in a List, then serialize that List out into a file. In the onResume() or onStart() method, deserialize this data from the file.
An example for such serialization is shown here, but I'll also paste it here:
Put objects into bundle
Serialization:
private List<String> list = new ArrayList<String>();
#Override
public void onPause()
{
super.onPause();
FileOutputStream out = null;
try
{
out = openFileOutput("ModelBackup",Context.MODE_PRIVATE);
try
{
ObjectOutputStream oos = new ObjectOutputStream(out);
oos.writeObject(list);
}
catch(IOException e)
{
Log.d(this.getClass().toString(), e.getMessage());
}
}
catch(FileNotFoundException e)
{
Log.d(this.getClass().toString(), e.getMessage());
}
finally
{
try
{
if(out != null) out.close();
}
catch(IOException e)
{
Log.d(this.getClass().toString(), e.getMessage());
}
}
}
Deserialization:
#Override
public void onResume()
{
super.onResume();
FileInputStream in = null;
try
{
in = openFileInput("ModelBackup");
ObjectInputStream oos = new ObjectInputStream(in);
try
{
list = (List<String>)oos.readObject();
}
catch(ClassNotFoundException e)
{
list = null;
}
}
catch(IOException e)
{
Log.d(this.getClass().toString(), e.getMessage());
}
finally
{
try
{
if(in != null) in.close();
}
catch(IOException e) {}
}
}
If restarting an activity from a fragment, I would do it like so:
new Handler().post(new Runnable() {
#Override
public void run()
{
Intent intent = getActivity().getIntent();
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_NO_ANIMATION);
getActivity().overridePendingTransition(0, 0);
getActivity().finish();
getActivity().overridePendingTransition(0, 0);
startActivity(intent);
}
});

Image uploading on Facebook

Toast.makeText(getApplicationContext(),"yoohooo ",Toast.LENGTH_SHORT).show();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
Toast.makeText(getApplicationContext(), "no", Toast.LENGTH_SHORT).show();
}
}
});
}
#Override
public void onError(SocialAuthError error) {
Log.d("ShareButton", "Authentication Error: " + error.getMessage());
}
#Override
public void onCancel() {
Log.d("ShareButton", "Authentication Cancelled");
}
#Override
public void onBack() {
Log.d("Share-Button", "Dialog Closed by pressing Back Key");
}
}
// To get status of message after authentication
private final class UploadImageListener implements SocialAuthListener<Integer> {
#Override
public void onExecute(String provider, Integer t) {
Log.d("Custom-UI", "Uploading Data");
Integer status = t;
Log.d("Custom-UI", String.valueOf(status));
Toast.makeText(getApplicationContext(), "Image Uploaded", Toast.LENGTH_SHORT).show();
}
#Override
public void onError(SocialAuthError arg0) {
// TODO Auto-generated method stub
}
}
}
Every time i click the update button a "no" message is printed on toast. Although the program does not show any error. I would be really greatfull if anybody can help me out on this.

Facebook Login/Google Login - Same Activity?

I am trying to give my users the option to sign in with either Google or Facebook. So far I found an example to implement a Google Sign in Flow, but I am confused if I can implement a similar Facebook Login Flow within the same Activity.
Anyone have an Idea as to handle the Logins? I was thinking about potentially defining a class to handle the Login Flows for both Google / Facebook, and perhaps just check to see which is being used when the app launches. Any Ideas?
public class MainActivity extends Activity implements ConnectionCallbacks,
OnConnectionFailedListener, OnClickListener, OnAccessRevokedListener {
private static final String TAG = "MainActivity";
// A magic number we will use to know that our sign-in error
// resolution activity has completed.
private static final int OUR_REQUEST_CODE = 49404;
// The core Google+ client.
private PlusClient mPlusClient;
// A flag to stop multiple dialogues appearing for the user.
private boolean mResolveOnFail;
// We can store the connection result from a failed connect()
// attempt in order to make the application feel a bit more
// responsive for the user.
private ConnectionResult mConnectionResult;
// A progress dialog to display when the user is connecting in
// case there is a delay in any of the dialogs being ready.
private ProgressDialog mConnectionProgressDialog;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
// We pass through this for all three arguments, specifying the:
// 1. Context
// 2. Object to call onConnected and onDisconnected on
// 3. Object to call onConnectionFailed on
mPlusClient = new PlusClient.Builder(this, this, this)
.setVisibleActivities("http://schemas.google.com/BuyActivity")

// We use mResolveOnFail as a flag to say whether we should trigger
// the resolution of a connectionFailed ConnectionResult.

findViewById(R.id.sign_out_button).setOnClickListener(this);
findViewById(R.id.sign_out_button).setVisibility(View.GONE);

// Configure the ProgressDialog that will be shown if there is a
// delay in presenting the user with the next sign in step.
mConnectionProgressDialog = new ProgressDialog(this);
mConnectionProgressDialog.setMessage("Signing in...");
}
#Override
protected void onStart() {
super.onStart();
Log.v(TAG, "Start");
// Every time we start we want to try to connect. If it
// succeeds we'll get an onConnected() callback. If it
// fails we'll get onConnectionFailed(), with a result!
mPlusClient.connect();
}
#Override
protected void onStop() {
super.onStop();
Log.v(TAG, "Stop");
// It can be a little costly to keep the connection open
// to Google Play Services, so each time our activity is
// stopped we should disconnect.
mPlusClient.disconnect();
}
#Override

set both fragments (facebook and google) in the layout that you use as login and in another to receive the session validated

android:id="#+id/sign_in_button"
android:layout_below="#id/authButton"

in the new activity place the same functions to validate the sesion and use
if (session.isOpened()) { }
to hide google login button or
public void onConnected(Bundle connectionHint)
{
}
to hide facebook login button
