I have made a google sign up button using the link
However, on execution, the pop-up window that usually appears for choosing a google account does not appear.
I have added an onClick option on the google sign-in button and used the function googleSignUp().
Below, I have put code I have used

}
I am getting no errors but the code does not give the desired result.
In the official documentation example:
https://github.com/firebase/quickstart-android/blob/8262596a009b50b6c99191001f7e5470391bcc4a/auth/app/src/main/java/com/google/firebase/quickstart/auth/java/GoogleSignInActivity.java#L71-L75
The code that declares and configures the GoogleSignInOptions is in the onCreate() method rather than in the class like your example shows. Perhaps instead of
public class MainActivity extends AppCompatActivity {
// you declared it here
public void onCreate() {
// rather than here
}
}
try putting it in the onCreate method
public class MainActivity extends AppCompatActivity {
public void onCreate() {
// declare and build it here
GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
}
}

Anybody know how to fix it?

private BiometricPrompt biometricPrompt;
private BiometricPrompt.PromptInfo promptInfo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
auth_button = findViewById(R.id.btn2);

Executor executor = ContextCompat.getMainExecutor(this);
biometricPrompt = new BiometricPrompt(MainActivity.this, executor, new

#Override

super.onAuthenticationError(errorCode, errString);
Toast.makeText(MainActivity.this,"Error:"+errString,
Toast.LENGTH_SHORT).show();
}
#Override

BiometricPrompt.AuthenticationResult result) {
super.onAuthenticationSucceeded(result);
Toast.makeText(MainActivity.this,"Authorized", Toast.LENGTH_SHORT).show();
}
#Override

}
});
promptInfo = new BiometricPrompt.PromptInfo.Builder().setTitle("Biometric
Authorization").setSubtitle("login using Finger print")
.setNegativeButtonText("Cancel").build();
auth_button.setOnClickListener(v -> biometricPrompt.authenticate(promptInfo));
}
}
I want the function to go to the new layout if the authentication is successful.
But whenever I try using intent with looping statements the code breaks and goes in an infinite
loop.
How do I overcome this problem such that the code reaches the next layout like on successful authentication.
I am creating a chat app in which Users can create groups. when a users creates a group, he/she can choose a group profile image. but if i choose the image, it wont upload. what to do?
I have inspected the code, there is no error anywhere

I fixed it by moving the code in the on success listener itself

I have this code that initializes text to speech. However, text to speech takes around ten seconds to load so I would like it to be done in async. How can I do this without changing the functionality of my code?
import java.util.Locale;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.content.res.Resources;
import android.view.Window;
import android.view.WindowManager;
import android.widget.TextView;
import android.widget.Button;
import java.lang.String;
import java.util.Random;
public class MainActivity extends Activity implements TextToSpeech.OnInitListener{
TextToSpeech tts;
private static final Random r_generator = new Random();
String textViewString;
int MY_DATA_CHECK_CODE = 1234;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
Resources res = getResources();
TextView tv = (TextView) findViewById(R.id.animal_text);
String loadingString = res.getString(R.string.Loading);
tv.setText(loadingString);
Intent checkIntent = new Intent();
checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);
}
protected void onActivityResult(
int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
tts = new TextToSpeech(this, this);
} else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}
#Override
public void onInit(int status) {
int result=tts.setLanguage(Locale.US);
if(result==TextToSpeech.LANG_MISSING_DATA ||
result==TextToSpeech.LANG_NOT_SUPPORTED){
Log.e("error", "This Language is not supported");
}
Resources res = getResources();
TextView tv = (TextView) findViewById(R.id.animal_text);
String[] myString = res.getStringArray(R.array.englishAnimalArray);
String q = myString[r_generator.nextInt(myString.length)];
tv.setText(q);
textViewString = tv.getText().toString();
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
tts.speak(textViewString, TextToSpeech.QUEUE_FLUSH, null);
} else {
tts.speak(textViewString, TextToSpeech.QUEUE_FLUSH, null, null);
}
}
I'd suggest you can take this by using AsyncTask.
An AsyncTask works as follows:
private ProgressDialog pDialog; // Progress Dialog to load during the AsyncTask
private class InitializeSpeechEngine extends AsyncTask<Void, Void, Void>{
#Override
protected void onPreExecute(Void aVoid){
// Initialization code goes inside onPreExecute
pDialog = new ProgressDialog(MainActivity.this);
pDialog.setTitle("Loading Speech to Text Engine");
pDialog.setMessage("Please Wait...");
pDialog.setCancellable(false);
pDialog.show();
}
#Override
protected void doInBackground(Void... params){
// Perform the speech to text initialization here
}
#Override
protected void onPostExecute(Void aVoid){
// Display Toast that the engine is ready for use.
pDialog.dismiss();
Toast.makeText(MainActivity.this, "Speech to text engine initialization complete", Toast.LENGTH_SHORT).show();
}
#Override
protected void onProgressUpdate(Void... params){
}
You can start executing the AsyncTask by making the following call.
new InitialiazeSpeechEngine().execute();
