Why negativeButton is "invisible"?

I'm trying to build an app with biometric authentication (Fingerprint) and I'm having some troubles with the negative button.
The button works, but for some reason is completely invisible.
This is how the app shows
And this is how it sees when you prees the button. As you can see, it exist, but i don't know how to make it visible
I'm using BiometricPrompt and BiometricManager in Java.
Edit: It seems that the button shows normally in any other phone that isn't mine
I'm using a Xiaomi Redmi Note 8.
However this is the code that I'm using:
private void initViews()
{
biometricManager = BiometricManager.from(this);
passwordEditText=findViewById(R.id.passwordText);
loginButton=findViewById(R.id.loginButton);
switch (biometricManager.canAuthenticate()) {
case BiometricManager.BIOMETRIC_SUCCESS:
Log.d("MY_APP_TAG", "App can authenticate using biometrics.");
break;
case BiometricManager.BIOMETRIC_ERROR_NO_HARDWARE:
Log.e("MY_APP_TAG", "No biometric features available on this device.");
break;
case BiometricManager.BIOMETRIC_ERROR_HW_UNAVAILABLE:
Log.e("MY_APP_TAG", "Biometric features are currently unavailable.");
break;
case BiometricManager.BIOMETRIC_ERROR_NONE_ENROLLED:
Log.e("MY_APP_TAG", "The user hasn't associated " +
"any biometric credentials with their account.");
break;
}
executor = ContextCompat.getMainExecutor(this);
biometricPrompt = new BiometricPrompt(EnterYourPassActivity.this,
executor, new BiometricPrompt.AuthenticationCallback() {
#Override
public void onAuthenticationError(int errorCode,
#NonNull CharSequence errString) {
super.onAuthenticationError(errorCode, errString);
if(errString.equals("Use account password"))
{
passwordEditText.setVisibility(View.VISIBLE);
}
else
{
Log.d("MY_APP_TAG",""+errString);
Toast.makeText(getApplicationContext(),
"Authentication error: " + errString, Toast.LENGTH_SHORT)
.show();
}
}
#Override
public void onAuthenticationSucceeded(
#NonNull BiometricPrompt.AuthenticationResult result) {
super.onAuthenticationSucceeded(result);
Toast.makeText(getApplicationContext(),
"Authentication succeeded!", Toast.LENGTH_SHORT).show();
Intent seeingFiles = new Intent(EnterYourPassActivity.this, SeeingFilesActivity.class);
startActivity(seeingFiles);
}
#Override
public void onAuthenticationFailed() {
super.onAuthenticationFailed();
Toast.makeText(getApplicationContext(), "Authentication failed",
Toast.LENGTH_SHORT)
.show();
}
});
promptInfo = new BiometricPrompt.PromptInfo.Builder()
.setTitle("Biometric login for my app")
.setSubtitle("Log in using your biometric credential")
.setNegativeButtonText("Use account password")
.build();
loginButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
biometricPrompt.authenticate(promptInfo);
}
});
}

Try to change negativeButton text in this way:
Important - put string into resources:
<string name="negative_button_text"><![CDATA[<font color=\'#48a134\'>Your text at given color</font>]]></string>
As you can see, you can set text color in hex.
Now put negativeText into BiometricPrompt as follows:
val negativeButtonText = getString(R.string.negative_button_text)
val promptInfo = BiometricPrompt.PromptInfo.Builder()
.setTitle("title")
.setDescription("description")
.setNegativeButtonText(fromHtml(negativeButtonText))
.build()
fun fromHtml(html: String): Spanned {
return HtmlCompat.fromHtml(html, HtmlCompat.FROM_HTML_MODE_LEGACY)
}
In given example negativeText is green and prompt looks like THIS.

Mobile OTP Verification without signing in using Firebase Phone Auth

I am currently making an android app where I need to verify if the user is entering correct mobile number using the OTP.
The user is already signed in the application using his email and password.
Now I need to verify the mobile number the user enters without using the signInWithCrendntial() method of firebase phone auth.
How do i go about it ?
My mCallbacks is
#Override
public void onVerificationCompleted(PhoneAuthCredential credential) {
Toast.makeText(getApplicationContext(), "Verification Complete", Toast.LENGTH_SHORT).show();
showMessage("Success!!","OTP verified!" + credential);
cred = credential;
//btn_add_guest.setEnabled(true);
}
#Override
public void onVerificationFailed(FirebaseException e) {
Toast.makeText(getApplicationContext(), "Verification Failed", Toast.LENGTH_SHORT).show();
Log.i(TAG,"Error is "+e.getMessage());
}
#Override
public void onCodeSent(String verificationId,
PhoneAuthProvider.ForceResendingToken token) {
Toast.makeText(getApplicationContext(), "Code Sent", Toast.LENGTH_SHORT).show();
mVerificationId = verificationId;
mResendToken = token;
Log.i(TAG,"VERFICATION ID IS"+mVerificationId);
Log.i(TAG,"RESEND TOKEN"+mResendToken);
btn_add_guest.setEnabled(false);
}
};
I m calling this method on button Pressed where put_otp is textView where user enters the OTP.
verifyPhoneNumberWithCode(mVerificationId,put_otp.getText().toString());
PhoneAuthCredential credential = PhoneAuthProvider.getCredential(mVerificationId, put_otp.getText().toString());
Log.i(TAG,credential.getProvider());
private void verifyPhoneNumberWithCode(String verificationId, String code) {
Log.i(TAG,"RESEND TOKEN IN METHOD IS"+mResendToken); if(code.equals(mResendToken)&&verificationId.equals(mVerificationId)){
Toast.makeText(AddGuestActivity.this, "Verification Success", Toast.LENGTH_SHORT).show();
btn_add_guest.setEnabled(true);
}
else
Toast.makeText(this,"Please provide correct OTP",Toast.LENGTH_SHORT).show();
}

You can link an email/pass account with a phone account https://firebase.google.com/docs/auth/android/account-linking?authuser=0

Firebase not firing a success or unsuccess

I've followed the instructions exactly, in fact, I even used the code from the Firebase helper in android studio. My issue is as such, nor login or failure to login is occurring with my code! What am I missing?
public void toSubscribe(View v) {
Log.d("OK", "this part first");
String strUsername, strPassword;
strUsername = ((EditText) findViewById(R.id.username)).getText().toString();
strPassword = ((EditText) findViewById(R.id.password)).getText().toString();
if (strUsername.matches("")) {
Toast.makeText(MainActivity.this, "You did not enter a username.", Toast.LENGTH_SHORT).show();
return;
}
if (strPassword.matches("")) {
Toast.makeText(MainActivity.this, "You did not enter a password.", Toast.LENGTH_SHORT).show();
return;
}
mAuth.signInWithEmailAndPassword(strUsername, strPassword)
.addOnCompleteListener(MainActivity.this, new OnCompleteListener<AuthResult>() {
#Override
public void onComplete(#NonNull Task<AuthResult> task) {
Log.d("TAG", "signInWithEmail:onComplete:" + task.isSuccessful());
// If sign in fails, display a message to the user. If sign in succeeds
// the auth state listener will be notified and logic to handle the
// signed in user can be handled in the listener.
if (!task.isSuccessful()) {
Log.w("TAG", "signInWithEmail", task.getException());
Toast.makeText(MainActivity.this, "Authentication failed.",
Toast.LENGTH_SHORT).show();
}
}
});
}
Not much else to say... I tried using a new JSON file and it still doesn't work. I've Googled tons of stuff but nothing really worked.

please check the following:
1-you install and add Gson file correctly from firebase console
2- you enable firebase authentication from firebase console
3- you mAuth initialized correctly

Android: Google Sign in Integration with Sashido (Parse.com SDK) without Cloud Code

I'm writing this question and answer because I haven't seen a full solution to the integration of Google sign in on Android using Facebook's Parse SDK (or Sashido in my case) as a back-end without cloud code.
Related Questions:

How would one go about integrating Google Sign in with Parse back-end without Cloud Code?

First of all, follow the steps provided by Android Developers on starting and implementing the integration.
Start Integrating Google Sign-In into Your Android App
Integrating Google Sign-In into Your Android App
In the onCreate your activity you need to build the GoogleSignInOptions
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestIdToken(getString(R.string.default_web_client_id))
.requestEmail()
.build();
You can get your web_client_id when you add Google Services to your project to your Google Developers account. Find out more at: Creating a Google API Console project and client ID
Build your GoogleApiClient (make it a global instance private GoogleApiClient mGoogleApiClient;)
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() {
#Override
public void onConnectionFailed(#NonNull ConnectionResult connectionResult) {
Log.e("Failed", "failed" + connectionResult.getErrorMessage());
}
})
.addApi(Auth.GOOGLE_SIGN_IN_API, gso)
.build();
Listen out for the click on the dedicated button for your Google sign in and then start a Auth.GoogleSignInApi.getSignIntent(mGoogleApiClient);
case R.id.btn_google:
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
break;
Make sure you've assigned a value to RC_SIGN_IN (I've done 1000)
Now start adding implementation to your onActivityResult method
// Result returned from launching the Intent from
// GoogleSignInApi.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {
GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
handleSignInResult(result);
} else {
ParseFacebookUtils.onActivityResult(requestCode, resultCode, data);
}
Now to handle the sign in request:
`private void handleSignInResult(GoogleSignInResult result) {
Log.e("handleSignIn", "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
final GoogleSignInAccount acct = result.getSignInAccount();
if (acct != null) {
ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
query.setLimit(10000);
query.whereEqualTo("email", acct.getEmail());
query.findInBackground(new FindCallback<ParseObject>() {
#Override
public void done(List<ParseObject> objects, ParseException e) {
if (e == null) {
if (objects.size() == 0) {
saveNewUserGoogle(acct);
} else {
loginGoogleUser(objects.get(0), acct);
}
} else {
saveNewUserGoogle(acct);
}
}
});
}
} else {
Log.e("failed", "failed to sign in");
// Signed out, show unauthenticated UI.
}
}`
So what this method does is if the request to the GoogleSignIn Request is successful, get the account details, query the _User table in your database and to see if the email with the account matches. If it does, Log the user in.
private void loginGoogleUser(ParseObject j, GoogleSignInAccount acct) {
ParseUser.logInInBackground(j.getString("username"), String.valueOf(acct.getId()), new LogInCallback() {
public void done(ParseUser user, ParseException e) {
if (user != null) {
Intent i = new Intent(AllLoginActivity.this, MainActivity.class);
startActivity(i);
finish();
} else {
Log.e("failed", "could not be validated");
}
}
});
}
else sign the user up:
private void saveNewUserGoogle(GoogleSignInAccount acct) {
google = true;
final ParseUser user = new ParseUser();
String mFullName = acct.getDisplayName();
String mEmail = acct.getEmail();
String mProfilePic = String.valueOf(acct.getPhotoUrl());
String mUsername = acct.getId();
String password = acct.getId();
user.setUsername(mUsername);
user.setEmail(mEmail);
user.setPassword(password);
user.put("userEmail", mEmail);
user.put("uniqueID", mUsername);
user.put("name", mFullName);
user.put("loginMethod", "Google");
user.put("profilePicture", mProfilePic);
user.signUpInBackground(new SignUpCallback() {
public void done(ParseException e) {
if (e == null) {
Log.e("SaveTest", "Successful");
//sign user up
} else {
switch (e.getCode()) {
case ParseException.USERNAME_TAKEN:
Toast.makeText(context, "Sorry, this username has already been taken.", Toast.LENGTH_SHORT).show();
break;
case ParseException.USERNAME_MISSING:
Toast.makeText(context, "Sorry, a username is needed", Toast.LENGTH_SHORT).show();
break;
case ParseException.PASSWORD_MISSING:
Toast.makeText(context, "Sorry, a password is needed.", Toast.LENGTH_SHORT).show();
break;
case ParseException.OBJECT_NOT_FOUND:
Toast.makeText(context, "invalid credentials", Toast.LENGTH_SHORT).show();
break;
case ParseException.CONNECTION_FAILED:
Toast.makeText(context, "Sorry, internet is needed.", Toast.LENGTH_SHORT).show();
break;
default:
Log.d("Testing", e.getLocalizedMessage());
break;
}
}
}
});
}
So for this if you set the password on Parse as the clientID it'll be unique to that user and can be read by Parse and given by Google.
Note: I'm setting the username as the Google Identifier and then when they have successfully connected and signed up I display a username dialog box where they enter a username, so it can be displayed as something in plain text rather than numerics.

Getting a Malformed access token "t ​ype":"OAuthException","code":190

I am writing an android application to get the Facebook user albums and photos and display in my Android application.
I have created a Facebook App with APP_ID 281846961912565.
While creating the Facebook instance, I am passing this id as follows
facebook = new Facebook(APP_ID);
Using this instance, I am able to login to my FB account post on messages on facebook wall programatically.
After logging in, I get an access_token.
I'm using the access token to get the album ids using facebook.request("https://graph.facebook.com/me/albums?access_token="+facebook.getAccessToken());
Now I get {"error":{"message":"Malformed access token ACCESSTOKENACCESSTOKEN?access_token=ACCESSTOKENACCESSTOKEN","t‌​ype":"OAuthException","code":190}}
Can any of you please help me resolve this issue and point out what i am doing wrong.
My code is as follows:
private static final String[] PERMISSIONS = new String[] { "publish_stream","user_photos" };
public boolean saveCredentials(Facebook facebook) {
Editor editor = getApplicationContext().getSharedPreferences(KEY,
Context.MODE_PRIVATE).edit();
editor.putString(TOKEN, facebook.getAccessToken());
editor.putLong(EXPIRES, facebook.getAccessExpires());
return editor.commit();
}
public boolean restoreCredentials(Facebook facebook) {
SharedPreferences sharedPreferences = getApplicationContext()
.getSharedPreferences(KEY, Context.MODE_PRIVATE);
facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
return facebook.isSessionValid();
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
facebook = new Facebook(APP_ID);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.facebook_dialog);
String facebookMessage = getIntent().getStringExtra("facebookMessage");
if (facebookMessage == null) {
facebookMessage = "Test wall post";
}
messageToPost = facebookMessage;
}
R.layout.facebook_dialog is the dialog which pops up asking if a message should be shared on facebook or not. If yes the following method is called.
public void share(View button) {
if (!facebook.isSessionValid()) {
loginAndPostToWall();
} else {
postToWall(messageToPost);
}
}
public void loginAndPostToWall() {
facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH,
new LoginDialogListener());
}
class LoginDialogListener implements DialogListener {
public void onComplete(Bundle values) {
saveCredentials(facebook);
if (messageToPost != null) {
postToWall(messageToPost);
}
}
public void onFacebookError(FacebookError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onError(DialogError error) {
showToast("Authentication with Facebook failed!");
finish();
}
public void onCancel() {
showToast("Authentication with Facebook cancelled!");
finish();
}
}
public void postToWall(String message) {
Bundle parameters = new Bundle();
parameters.putString("message", message);
parameters.putString("description", "topic share");
try {
facebook.request("me");
String response = facebook.request("me/feed", parameters, "POST");
Log.d("Tests", "got response: " + response);
if (response == null || response.equals("")
|| response.equals("false")) {
showToast("Blank response.");
} else {
showToast("Message posted to your facebook wall!");
}
getImagesFromUserAlbum();
finish();
} catch (Exception e) {
showToast("Failed to post to wall!");
e.printStackTrace();
finish();
}
}
Later when I do a `private void getImagesFromUserAlbum() {
facebook.getAccessToken();
JSONArray albumss = null;
String response = null;
try {
response = facebook.request("me/albums");
// `
I get the error
{"error":{"message":"Malformed access token ACCESSTOKEN?access_token=ACCESSTOKEN","type":"OAuthException","code":190}}
Thanks for your help.
The code above is now the working copy. Thanks to Bartek.

If you look at the Errors page in the documentation you will see that when you get error 190 you should authorise/reauthorise the user.
I suspect that this happened to you because you first logged in, then added the permissions to access the albums to your application BUT did not log out and log back in. Hence, you need to obtain a new access token which will grant the new permissions to your application.

Please check is there &expires in your access token if yes then remove it because it is not part of access_token and try after that.
