discussing getActivityResult in class

There must be a way to get intent result in a class without using onActivityResult. By using other methods...
I dont know how, but Iam sure there is a way.
My class that should get the result of the intent filepicker from this class without using onActivityResult in the MainActivity.java that extents activity. FilePicker.java
package com.hadiawali.codeeditor;
import android.content.Intent;
import android.app.Activity;
import android.net.Uri;
import android.os.Bundle;
public class FilePicker {
Intent filePicker = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
public static void startPicking(Activity activity) {
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.LOLLIPOP) {
Intent chooseFolder = new Intent(Intent.ACTION_OPEN_DOCUMENT_TREE);
chooseFolder.addCategory(Intent.CATEGORY_DEFAULT);
activity.startActivityForResult(Intent.createChooser(chooseFolder, "Choose directory"), 9999);
}
}
}
My class that extents activity. MainActivity.java
package com.hadiawali.codeeditor;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import androidx.appcompat.app.AppCompatActivity;
public class MainActivity extends AppCompatActivity {
Button btn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btn = findViewById(R.id.btn);
btn.setOnClickListener(
new View.OnClickListener() {
public void onClick(View v) {
FilePicker.startPicking(MainActivity.this);
//I need to get the intent reslut from the class without using onActivityResult
}
});
}
}

For example you send to intent from activity A to B then
in Activity A create Activity Result like below
ActivityResultLauncher<Intent> someActivityResultLauncher = registerForActivityResult(new ActivityResultContracts.StartActivityForResult(), new ActivityResultCallback<ActivityResult>() {
#Override
public void onActivityResult(ActivityResult result) {
if (result.getResultCode() == Activity.RESULT_OK) {
// callback called
}
}
});
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//call B activity
someActivityResultLauncher.launch(intent);
}
in Activity B your task is successfully complete then set
setResult(RESULT_OK);
finish();
or if task is not complete successfully then put
setResult(RESULT_CANCELED);
finish();

How to share tts as and audio file in android studio

I'm new to programming, and I'm creating an app with texttospeech and I wanna be able to share the tts output as an audio file to other apps like whatsapp for example. I have heard about synthesizetofile() but I don't know anything about it.
Here's my code:
Main Activity class
package com.example.texttospeech;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.speech.tts.TextToSpeech;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import androidx.appcompat.app.AppCompatActivity;
import java.io.File;
import java.util.HashMap;
import java.util.Locale;
public class MainActivity extends AppCompatActivity {
EditText etInput;
Button btDone, btShare;
MediaPlayer mMediaPlayer;
TextToSpeech textToSpeech;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
etInput = findViewById(R.id.et_input);
btDone = findViewById(R.id.bt_done);
btShare = findViewById(R.id.btn_share);
textToSpeech = new TextToSpeech(getApplicationContext()
, new TextToSpeech.OnInitListener() {
#Override
public void onInit(int i) {
if (i == TextToSpeech.SUCCESS) {
int lang = textToSpeech.setLanguage(Locale.ENGLISH);
}
}
});
btDone.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//String s = etInput.getText().toString();
//int speech = textToSpeech.speak(s, TextToSpeech.QUEUE_FLUSH, null);
HashMap<String, String> map = new HashMap<>();
map.put(TextToSpeech.Engine.KEY_PARAM_UTTERANCE_ID, "speak");
File myDir = getApplicationContext().getFilesDir();
String documents = "documents/data";
File documentsFolder = new File(myDir, documents);
documentsFolder.mkdir();
String path = "/"+documents+"/"+"test.mp3";
textToSpeech.synthesizeToFile("text to speech to audio", map, path);
mMediaPlayer = new MediaPlayer();
try{
mMediaPlayer.setDataSource(path);
mMediaPlayer.prepare();
}
catch (Exception e) {
Log.d("ROYs", e.toString());
e.printStackTrace();
}
mMediaPlayer.start();
}
});
btShare.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Bundle bundle = new Bundle();
Intent intent = new Intent( Intent.ACTION_SEND );
intent.setType("audio/mp3");
startActivity( intent );
}
});
}
private void shareAudio()
{
Bundle bundle = new Bundle();
Intent intent = new Intent( Intent.ACTION_SEND );
intent.setType("audio/mp3");
startActivity( intent );
}
}
Anyone who helps, would be appreciated very much!

add data to listview from another activity

I'm really confused on how to add from another activity I keep getting an error in this part of the code:
Emails a = new Emails(intent.getStringExtra("inputEmail"), intent.getStringExtra("inputBody"), intent.getStringExtra("inputSubject"));
So the error says "actual and formal argument lists differ in length". if anyone could help me out it would be such a huge help thank you :)
this my code:
main activity:
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.ListView;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
private Button newEmail;
private ListView listView;
private EmailAdapter emailAdapter;
private ArrayList<Emails> emailsArrayList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
emailAdapter = new EmailAdapter(this, emailsArrayList);
listView.setAdapter(emailAdapter);
updateList();
newEmail.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, SendActivity.class);
startActivity(intent);
}
});
}
private void init(){
newEmail = (Button) findViewById(R.id.newBtn);
listView = (ListView) findViewById(R.id.list);
emailsArrayList = new ArrayList<>();
Emails emails = new Emails ();
emails.setEmails("josemari#yahey.com");
emails.setSubject("Sample Data");
emails.setBody("this is the sample data");
emailsArrayList.add(emails);
}
private void updateList()
{
Bundle bundle = getIntent().getExtras();
Intent intent = getIntent();
if(bundle != null)
{
Emails a = new Emails(intent.getStringExtra("inputEmail"), intent.getStringExtra("inputBody"), intent.getStringExtra("inputSubject"));
emailAdapter.add(a);
emailAdapter.notifyDataSetChanged();
}
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent intent)
{
super.onActivityResult(requestCode, resultCode, intent);
if(requestCode == 1 && resultCode == RESULT_OK)
{
Emails a = new Emails(intent.getStringExtra("inputEmail"), intent.getStringExtra("inputBody"), intent.getStringExtra("inputSubject"));
emailAdapter.add(a);
emailAdapter.notifyDataSetChanged();
}
}
#Override
protected void onStart() {
super.onStart();
Log.d("MainActivity","onStart invoked");
}
#Override
protected void onResume() {
super.onResume();
Log.d("MainActivity","onResume invoked");
}
#Override
protected void onPause() {
super.onPause();
Log.d("MainActivity","onPause invoked");
}
#Override
protected void onStop() {
super.onStop();
}
#Override
protected void onRestart() {
super.onRestart();
}
#Override
protected void onDestroy() {
super.onDestroy();
}
}
this is the add item activity:
import androidx.appcompat.app.AppCompatActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.Toast;
import java.util.ArrayList;
public class SendActivity extends AppCompatActivity {
private Button send;
private Button discard;
private EditText email;
private EditText subject;
private EditText body;
private ArrayList<Emails> emailsArrayList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_send);
send = (Button) findViewById(R.id.sendBtn);
discard = (Button) findViewById(R.id.discardBtn);
email = (EditText) findViewById(R.id.inputEmail);
subject = (EditText) findViewById(R.id.inputSubject);
body = (EditText) findViewById(R.id.inputBody);
discard.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(SendActivity.this, MainActivity.class);
startActivity(intent);
}
});
send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String inputEmail = email.getText().toString();
String inputSubject = subject.getText().toString();
String inputBody = body.getText().toString();
if (inputBody.isEmpty() || inputEmail.isEmpty() || inputEmail.isEmpty()){
Toast.makeText(SendActivity.this, "Please enter the following data", Toast.LENGTH_SHORT).show();
}
else {
emailsArrayList = new ArrayList<>();
Emails newEmails = new Emails ();
newEmails.setEmails(inputEmail);
newEmails.setSubject(inputSubject);
newEmails.setBody(inputBody);
emailsArrayList.add(newEmails);
Intent intent = new Intent();
getIntent().putExtra("inputEmail", inputEmail);
getIntent().putExtra("inputSubject", inputSubject);
getIntent().putExtra("inputBody", inputBody);
setResult(RESULT_OK, intent);
finish();
}
}
});
}
}

I would also change the following as well:
private void updateList()
{
Bundle bundle = getIntent().getExtras();
Intent intent = getIntent();
if(bundle != null)
{
Emails a = new Emails(intent.getStringExtra("inputEmail"), intent.getStringExtra("inputBody"), intent.getStringExtra("inputSubject"));
emailAdapter.add(a);
emailAdapter.notifyDataSetChanged();
}
}
to
private void updateList()
{
Intent intent = getIntent();
Bundle bundle = intent.getExtras();
if(bundle != null)
{
Emails a = new Emails(String)bundle.get("inputEmail"), (String)bundle.get("inputBody"), (String)bundle.get("inputSubject"));
emailAdapter.add(a);
emailAdapter.notifyDataSetChanged();
}
}
I would try this absolutley first: You may beable to use what you have and just change the Bundle bundle and Intent intent lines around in your updateList(). Again no expert but try that first and then above that second. I hope it works for you.

Google sign up pop-up does not appear for choosing accounts

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

#Override

super.onStart();
// Check if user is signed in (non-null) and update UI accordingly.
FirebaseUser currentUser = mAuth.getCurrentUser();
updateUI(currentUser);

#Override

});
}
}, 300000, 300000);
}
public void Clicked(View view){
Toast.makeText(this,"Hello User",Toast.LENGTH_SHORT).show();
mp.start();
}
public void googleSignUp(View view) {
GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
Intent signInIntent = mGoogleSignInClient.getSignInIntent();
startActivityForResult(signInIntent, RC_SIGN_IN);
}
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
// Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
if (requestCode == RC_SIGN_IN) {

// Signed in successfully, show authenticated UI.
updateGUI(account);
} catch (ApiException e) {
// The ApiException status code indicates the detailed failure reason.
// Please refer to the GoogleSignInStatusCodes class reference for more information.
Log.w("null", "signInResult:failed code=" + e.getStatusCode());
updateGUI(null);
}
}
private void updateGUI(Object o) {
Toast.makeText(this,"SignUP by google Successful?",Toast.LENGTH_SHORT).show();
}
private void updateUI(FirebaseUser account) {
if(account==null)
Toast.makeText(this,"NULL",Toast.LENGTH_SHORT).show();
else
Toast.makeText(this,"SignUP Successful?",Toast.LENGTH_SHORT).show();
}
}
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();
}
}

Place Picker loads to long, variables don't change correctly

I'm making a simple place picker program in android. I want to save some text when user choose a point on map with place picker. And the problem is when I click on button the place picker opens too long and variable which is responsible for place can't keep up change and dialog that responses for enter text never opens. I think, maybe problem is with threads, isn't it?

Please help me, what could go wrong?

Your problem is that the Place Picker communicates with your main activity asynchronously, so you're opening your dialog before it returns. Try waiting until Place Picker has returned before opening the dialog like so:
.
.
.
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.AddEventButton:
place = null;
callPlacePicker();
break;
}
}
.
.
.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == PLACE_PICKER_REQUEST) {
if (resultCode == RESULT_OK) {
place = PlacePicker.getPlace(this, data);
openDialog();
}
}
}
