Login Details using Content Provider, brings many loop

I want to create a Toast Text (about I haven't registered in the database) on the Login Activity. However, there is a problem when I put this Toast text. If I put it inside a while loop Cursor.MoveToNext(), it will loop as many times as many entries it has.
Inside the loop
if(cursor!=null)
{
{
int i = 0;
while(cursor.moveToNext())
{
if(cursor.getString(i).equals(input_email) && cursor.getString(i).equals(input_password))
{
Log.d(TAG, "Udah masuk belum " );
Toast.makeText(getApplicationContext(),"Login Successful!", Toast.LENGTH_SHORT).show();
Intent intent =new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
i = i + 1;
}
else
{
Toast.makeText(getApplicationContext(),"You haven't Registered yet!", Toast.LENGTH_SHORT).show();
Intent intent =new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
}
}
cursor.close();
}
}
But when I putted outside of the loop, it brings error. Do you know what is the solution of this one?
Outside the loop
String [] projection ={ServiceProvidersContract.Columns.SEmail, ServiceProvidersContract.Columns.spPassword};
Cursor cursor = contentResolver.query(ServiceProvidersContract.CONTENT_URI, projection, null, null, null);
Log.d(TAG, "Checking Cursor" + cursor );
if(cursor!=null)
{
{
int i = 0;
while(cursor.moveToNext())
{
if(cursor.getString(i).equals(input_email) && cursor.getString(i).equals(input_password))
{
Log.d(TAG, "Udah masuk belum " );
Toast.makeText(getApplicationContext(),"Login Successful!", Toast.LENGTH_SHORT).show();
Intent intent =new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
i = i + 1;
}
}
cursor.close();
if(!cursor.getString(i).equals(input_email) && cursor.getString(i).equals(input_password))
{
Toast.makeText(getApplicationContext(),"You haven't Registered yet!", Toast.LENGTH_SHORT).show();
Intent intent =new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
}
}
}

Just want to clarify, I did finally login successfully in my login parts using For and While.
The other problem is coming from the Toast Text ( where I couldn't put the failed Toast Text in the loop). This is my codes :
private static final String TAG = "LoginActivity";
private Button btnLogin, btnLinkToRegister;
private SessionManager session;
private EditText password, email;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
// Defining everything
email = (EditText) findViewById(R.id.email);
password = (EditText) findViewById(R.id.password);
btnLinkToRegister = (Button) findViewById(R.id.btnLinkToRegister);
btnLogin = (Button) findViewById(R.id.btnLogin);
// Login button Click Event
btnLogin.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
ContentResolver contentResolver = getContentResolver() ;
String input_email = email.getText().toString().trim();
String input_password = password.getText().toString().trim();
Log.d(TAG, "onClick: " + input_email + input_password);
// Check for empty data in the form
if (!input_email.isEmpty() && !input_password.isEmpty()) {
Log.d(TAG, "onClick: if statement succeseful");
// checking from the database
String [] projection ={ServiceProvidersContract.Columns.SEmail, ServiceProvidersContract.Columns.spPassword};
Cursor cursor = contentResolver.query(ServiceProvidersContract.CONTENT_URI, projection, null, null, null);
Log.d(TAG, "Checking Cursor" + cursor );
if(cursor!=null)
{
cursor.moveToFirst();
while(cursor.moveToNext())
{
Log.d(TAG, "while process");
for(int i=0; i<cursor.getColumnCount(); i++)
{
Log.d(TAG, "for process " + cursor.getString(i));
if (cursor.getString(0).equals(input_email) && cursor.getString(1).equals(input_password)) {
Log.d(TAG, "if process");
Toast.makeText(getApplicationContext(), "Login Successful!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
break;
}
}
}
if (!cursor.getString(0).equals(input_email) && cursor.getString(1).equals(input_password)) {
Log.d(TAG, "if process");
Toast.makeText(getApplicationContext(), "You haven't registered yet!", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(intent);
finish();
}
cursor.close();
}
} else {
// Prompt user to enter credentials
Toast.makeText(getApplicationContext(),
"Please enter the credentials!", Toast.LENGTH_LONG)
.show();
}
}
});
btnLinkToRegister.setOnClickListener(new View.OnClickListener() {
public void onClick(View view){
Intent i = new Intent(LoginActivity.this, RegisterActivity.class);
startActivity(i);
finish();
}
});
}

jav.nullPointer .Exception when using Intent's putExtra() method

I keep getting a NulPpointerException, when I use the Intent's putExtras() method like shown below. It is in the onClick method where I create an intent and call the register activity class. I use android"s account authentication mechanism. Whenever the signUpTxt Textview is clicked, the app crushes and the error log trace below shows. What am I missing?
Here is my source code
public class LoginActivity extends AccountAuthenticatorActivity {
//.......................................

}
Iam passing the extras from Authenticator.java which extends AbstractAccountAuthenticator, in the addAccount() method
#Override
public Bundle addAccount(AccountAuthenticatorResponse response,
String accountType, String authTokenType,
String[] requiredFeatures, Bundle options)
throws NetworkErrorException {
Bundle result;
if (hasAccount(mContext)) {
result = new Bundle();
Intent i = new Intent(mContext, LoginActivity.class);
i.putExtra(LoginActivity.ARG_ACCOUNT_TYPE, accountType);
i.putExtra(LoginActivity.ARG_AUTH_TYPE, authTokenType);
i.putExtra(LoginActivity.ARG_IS_ADDING_NEW_ACCOUNT, true);
i.putExtra(AccountManager.KEY_ACCOUNT_AUTHENTICATOR_RESPONSE,response);
result.putParcelable(AccountManager.KEY_INTENT, i);
return result;
}

Based on the API:
Intent.getExtras() returns:
the map of all extras previously added with putExtra(), or null if none have been added
My guess would be that you are not passing in any extras and therefore passing null to the Intent.putExtras() method... Or if you think you are you may be doing so incorrectly.

From
getIntent().getStringExtra(ARG_ACCOUNT_NAME);
I can say thay you have used putStringExtra method, instead of putExtras.
Therefore, when you try getIntent().getExtras it is null.

Google+ login, fetching user data using new google services

I am implementing login with google using the new google services version 4.2, I am creating my google client as follows:
mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
.addApi(Plus.API)
.addScope(Plus.SCOPE_PLUS_PROFILE)
.addScope(Plus.SCOPE_PLUS_LOGIN)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
With only SCOPE_PLUS_LOGIN it does not work- internal error. However I can login using this ApiClient and following the instructions found at google. But whenever I am trying to access any information via
Plus.PeopleApi.getCurrentPerson(mGoogleApiClient)
The object is empty, I have added my SHA-1 key to my console, and have no idea what could go wrong.
Thanks for any answers

Try with this method:
private static final int REQUEST_CODE_GPLUS = 9000;
private static final String TAG_GPLUS = "google";
private ProgressDialog mProgressDialogGplus;
private PlusClient mPlusClient;
private ConnectionResult mConnectionResult;
mPlusClient = new PlusClient.Builder(SignUpActiivty.this, callbacks,
connectionFailedListener).setActions(
"http://schemas.google.com/AddActivity",
"http://schemas.google.com/BuyActivity")
// .setScopes(Scopes.PLUS_PROFILE) // recommended login scope
// for social features
.build();
mProgressDialogGplus = new ProgressDialog(SignUpActiivty.this);
mProgressDialogGplus.setCancelable(false);
mProgressDialogGplus.setMessage("Signing in...");
mProgressDialogGplus.show();
mPlusClient.connect();
Methods:
1. ConnectionCallbacks callbacks = new ConnectionCallbacks() {
public void onDisconnected() {
Log.v(TAG_GPLUS, "disconnected");
}
#Override
public void onConnected(Bundle arg0) {
Log.v(TAG_GPLUS, "onConnected");
mProgressDialogGplus.dismiss();
String accountName = mPlusClient.getAccountName();
Toast.makeText(SignUpActiivty.this, accountName + " is connected.",
Toast.LENGTH_LONG).show();
if (mPlusClient.getCurrentPerson() != null) {
Person currentPerson = mPlusClient.getCurrentPerson();
saveGooglePlusUserData(currentPerson);
}
}
};
2. OnConnectionFailedListener connectionFailedListener = new OnConnectionFailedListener() {
#Override
public void onConnectionFailed(ConnectionResult result) {
Log.v(TAG_GPLUS, "onConnectionFailed result = " + result);
if (mProgressDialogGplus.isShowing()) {
// The user clicked the sign-in button already. Start to resolve
// connection errors. Wait until onConnected() to dismiss the
// connection dialog.
if (result.hasResolution()) {
Log.v(TAG_GPLUS,
"onConnectionFailed result.hasResolution() = "
+ result);
try {
result.startResolutionForResult(SignUpActiivty.this,
REQUEST_CODE_GPLUS);
} catch (SendIntentException e) {
mPlusClient.connect();
}
}
}
// Save the intent so that we can start an activity when the user
// clicks the sign-in button.
mConnectionResult = result;
}
};
In onActivityResult :
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.v(TAG, "requestCode = " + requestCode + " resultCode = "
+ resultCode);
if (requestCode == REQUEST_CODE_GPLUS && resultCode == RESULT_OK) {
Log.v(TAG, "requestCode = " + requestCode + " resultCode = "
+ resultCode);
mConnectionResult = null;
mPlusClient = new PlusClient.Builder(SignUpActiivty.this,
callbacks, connectionFailedListener).setActions(
"http://schemas.google.com/AddActivity",
"http://schemas.google.com/BuyActivity").build();
mPlusClient.connect();
}
}
And method saveGooglePlusUserData is:
private void saveGooglePlusUserData(Person currentPerson) {
int gender_id = currentPerson.getGender();
Person.Name name = currentPerson.getName();
String account_id = currentPerson.getId();
String email = mPlusClient.getAccountName();
String bDate = currentPerson.getBirthday();
int ageGroup = countGPlusUserAge(bDate);
// Person.Name name = {"familyName":"surname","givenName":"Name"}
// BirthDate = 1988-04-24
String firstName = "";
String lastName = "";
try {
JSONObject jObj = new JSONObject(name.toString());
firstName = jObj.getString("givenName");
lastName = jObj.getString("familyName");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Log.v(TAG_GPLUS, "FirstName = " + firstName + " Name = " + name);
Log.v(TAG_GPLUS, "LastName = " + lastName);
Log.v(TAG_GPLUS, "Account_id = " + account_id);
Log.v(TAG_GPLUS, "Email = " + email);
Log.v(TAG_GPLUS, "Gender ID = " + gender_id);
Log.v(TAG_GPLUS, "BirthDate = " + bDate);
}
Hope this will help you.

When I used SCOPE_PLUS_PROFILE it would connect but I would get nothing when I used both scopes it would do the same and when I used just the login it wouldn't connect. For me the reason was because I changed my package name and I didn't change it in the client id on google developers console. You might not have exactly the same situation but try to check if your client id info is correct.

You must search the web to get Example.Bye the way Here is a link.3 minute to json
You must also go to this site to make everything clearJson
