Android If statement not breaking when condition is true

In this activity I am creating an account for users. I am using mobsandgeeks.saripaar API for validation features. To allow the activity to work I currently print the errors to an invisible text field, if this textfield has text, the activity does not go onto the next activity (i.e. there is an issue with user input).
I am having a problem with the if statement that checks if the username or email already exists in the database. When condition is true (checked in logs), the account is not created, but the 'Account created' message is still displayed and the application still goes to the next activity.
Any help on this would be much appreciated. Thanks

You have a problem in your condition:
Instead of:
else if (usernameExists == false | emailExists == false)
It should be:
else if (usernameExists == false && emailExists == false)
which means user/email not exist, insert them in DB and navigate to next activity.

Trying to keep user loggedIn in my android app after first login but not working

I am developing an android app, my app have a login activity. What i want to do is once a user is logged in for the first time it will remain logged in even if the app is closed.

Put this code in your onCreate()
SharedPreferences pref = getSharedPrefrences("login", Context.MODE_PRIVATE); //Opening 'login' sharedPreference
if(pref.getBoolean("LoggedIn", false)){ //checking if 'LoggedIn' exist in SharedPreference if no exist it returns false. if it exist fetches its value
//Move to Next Screen
} else {
loginButton.setOnClickListener(view -> login());
//Do other stuff
}
Then in your handleResponse().. Add these lines
//Lets suppose if User is logging in for the First time.. Below lines will add 'LoggedIn' to shared preference so user logged in directly next time
SharedPreferences.Editor editor = pref.edit();
editor.putBoolean("LoggedIn", true);
editor.apply();

Set LOGGEDIN_SHARED_PREF in your void handleResponse() as below :
editor.putBoolean(Constants.LOGGEDIN_SHARED_PREF,true);
Set your sharedPreferences globally
SharedPreferences sharedPreferences = getSharedPreferences(Constants.SHARED_PREF_NAME, Context.MODE_PRIVATE);
And edit on the same in your handleReponse()
SharedPreferences.Editor editor = sharedPreferences.edit();

How to get user data with SharedPreferences from RegisterActivity

}
}
i dont know what im missing that it dont verify the user if exists or login with the credentials i make in RegisterActivity.class
thanks

You are never retrieving the username and password from SharedPreferences. And at the end you are checking the information the user puts in the TextEdits against itself so the validation always returns true to any non empty value.
Change this:
SharedPreferences preference = getSharedPreferences("Reg",MODE_PRIVATE);
String username = mUsername.getText().toString();
String password = mPassword.getText().toString();
To this:
SharedPreferences preference = getSharedPreferences("Reg",MODE_PRIVATE);
String username = preference.getString("Username", "");
String password = preference.getString("Password", "");

How to: store image in sdcard, store and get imagepath in sharedpreferences for Profile Pic

Profile pic can be selected and set for a while but what we generally want (first object) is when user re-launch that page, there should be an image previously set by the user and if user has not set that image, there should be default image. I have used sharedpreferences for text views but it is said that for the image views, generally it is good practice to store the selected image first in sdcard, then get that Uri, make it string and then use it for sharedpreferences. i dont know if it can be done through onPause and onResume as well! if it is so, then which way should be prefer? and How to do that? Another thing is (Second object) i have an activity namely user profile where i want to inflate the data (Here, profile pic selected by the user) from edit profile activity. Here is the same case as of edit profile where if the user have not set custom profile pic then there should be default pic. Following is my edit profile activity:

Please consider that i have no experience in programming, coding or android development and i have just started to learn that!

You are right. You can store the image in your sd card and use the uri to load the image subsequently.
You can consider to save the image uri in the stored preference. With that you will just need to handle two cases.
In your onCreate() method
- Check if the image uri is valid (image exist)
- If it does, load it and make it the display image
- If it is missing, load the default image
* Alternatively, you can set the default image as the image for the imageview
Whenever the user updates the image
- Store the image into the sd card
- Update your shared preference
As such, you should not need to handle these in your onPause() and onResume() methods.
Hope it helps!

I have no much timer to write the entire answer, but here is how to store some Strings into the application shared Preferences:
1. storing some strings, it makes sense to store them when your "save"-button is clicked:
// assume a,b,c are strings with the information from ur edittexts to be saved:
String a,b,c;
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
SharedPreferences.Editor editor = sp.edit();
editor.putString("namekey",a);
editor.putString("UContact", b);
editor.putString("UEmail", c);
editor.commit();
now these 3 things are saved.
2. loading these values (e.g. in ur onCreate() method after setting the content):
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
// check if the namevalues "namekey", "UContact", "UEmail" have values saved in the sharedPreferences. If not, load defaultvalue
String user_name = sp.getString("namekey", "no name entered yet");
String user_email = sp.getString("UEmail", "no email entered yet");
String user_contact = sp.getString("UContact", "no Contact entered yet");
displayMessage(user_name);
displayUContact(user_contact);
displayUEmail(user_email);
Loading a value from the sharedPreferences always needs a 2nd parameter, which will be the result when there is nothing saved for this key. For example, if your application is started for the first time, and the user did not have entered anything in the edittexts, then "no name entered yet", and so on are loaded from the sharedPreferences.
and.. thats it so far.
Why did i not provide information on how to store a bitmap in the sharedPreferences?
- sharedPreferences can only store basic Types such as Float, Integer, String, Boolean
- You could save the image into the sd card, but remember: not every device is using a sd card. If your application uses the camera-intent instead, your foto is already saved in the gallery automatically. You can store this path as a String in the sharedPrefs.

We can have method to retrieve the Uri for selected image as below:
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
Uri uri = data.getData();
try {
Bitmap bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), uri);
// CALL THIS METHOD TO GET THE ACTUAL PATH
File finalFile = new File(getRealPathFromURI(uri));
outputFileUri = Uri.fromFile(finalFile);
stringUri = outputFileUri.toString();
// Log.d(TAG, String.valueOf(bitmap));
userImageView.setImageBitmap(bitmap);
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(Uimage, stringUri);
editor.apply();
} catch (IOException e) {
e.printStackTrace();
}
}
}
public String getRealPathFromURI(Uri uri) {
Cursor cursor = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
return cursor.getString(idx);
}
So now we have String that represents or has been stored with value of Uri for our selected image.
Next is to use this string for sharedpreferences as below:
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(Uimage, stringUri);
editor.apply();
Uimage is the key and it has string value stringUri with it! Each time user change the profile pic, we will have updated Uimage and associated stringUri at the same time.
Now, in onCreate method, we will check if there is sharedpreferences available with this value and if so, then we want to display the selected image. It should be noted here that sharedpreferences is used to save and keep the primitive data across re-launching of the app. Editor.putString is used to store some value and sharedpreferences.getString is used to read that value.
if (sharedpreferences.contains(Uimage)){
String imagepath = sharedpreferences.getString(Uimage, "");
uriString = Uri.parse(imagepath);
userImageView.setImageURI(uriString);
}
uriString is Uri!
And it worked!
Next is to send this profile pic to the user profile activity. We will use intent to send the selected pic to user profile activity and sharedpreferences in onCreate method of user profile activity to save and keep that pic there across re-launch as below:
1. Sending pic to the user profile activity using intent in edit profile activity as below:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_save:
Snackbar snackbar = Snackbar
.make(coordinatorLayout, "Saved!", Snackbar.LENGTH_LONG);
snackbar.show();
Intent userProfileIntent = new Intent(EditUserProfile.this, UserProfile.class);
if (sharedpreferences.contains(stringUri)){
userProfileIntent.putExtra(Uimage, stringUri);
}
setResult(RESULT_OK, userProfileIntent);
finish();
}
return true;
}
….and read and handle this intent at user profile activity as below:
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case Edit_Profile:
if (resultCode == RESULT_OK) {
String imageIntent = data.getStringExtra(Uimage);
displayUimage(imageIntent);
}
break;
}
}
Where:
public void displayUimage (String imageString){
ImageView importImage = (ImageView) findViewById(R.id.importImage);
imageString = sharedpreferences.getString(Uimage, "");
uriString = Uri.parse(imageString);
importImage.setImageURI(uriString);
}
Intent is used to get the pic from edit profile activity to user profile activity. If we press back or exit the app and re-launch it, user profile activity will lose that pic. In order to save and keep that pic there across re-launching of app, we need to use sharedpreferences there.
Save and Keep that pic there at user profile activity using sharedpreferences as below:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_profile);
Toolbar userProfileToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(userProfileToolbar);
importImage = (ImageView) findViewById(R.id.importImage);
importImage.setImageResource(R.drawable.defaultprofilepic);
sharedpreferences = getSharedPreferences(Uimage, MODE_PRIVATE);
if (sharedpreferences.contains(Uimage)){
String imagepath = sharedpreferences.getString(Uimage, "");
uriString = Uri.parse(imagepath);
importImage.setImageURI(uriString);
}
}
We first have initialized our importImage with the default one but then we check if there is sharedpreferences with special key is available.
That simply means, if the sharedpreferences contains Uimage (which is possible only if the user have changed the profile pic and the Uimage will be always updated as soon as user change the profile pic) then we will get Uri for that image and set it to importImage so that we will have same profile pic as user have selected at edit profile activity.

Sinch mobile verification Skipping

I have made an app in which first the user verifies its number with the help of sinch verification and then after succesfull verification it goes to the gameactivity but the problem is that every time the user opens the app he or she has to verify again which is a very bad out come.
i dont how o skip the verification process after again opening the app

I just want that on re opening verification process should not be again called.

You can use SharedPreferences. add a key to your SharedPreferences object and initialize with value 0. You can do something like below
SharedPrefences prefences = PrefenceManager.getSharedPreferences("TAG",Context.MODE_PRIVATE);
SharedPreferences.Editor editor = preferences.edit();
Now on successfull verification :
preferences.putInt("key",1);
so on next launch check for this key value, if its 1 skip the VerificationActivity and start GameActivtiy i.e
int value = preferences.getInt("key",0);
if(value == 0){
// Verify
}else{
// Skip Verification
}
