The Android does not talk despite my code being error free and accurate. I have used a toast function to see where the issue occurs. However, both toasts are called.
I have removed all irrelevant code.
The code below is mostly relevant.

String full = ("My name is"+toSpeak+ "and I am having a Seizure at 38.901 Latitude and -77.031 Longitude ");
Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show();
talker.speak(full, TextToSpeech.QUEUE_FLUSH, null);
Toast.makeText(getApplicationContext(), full, Toast.LENGTH_SHORT).show();
talker.speak("HELLO",TextToSpeech.QUEUE_FLUSH, null);
}
}
There are several problems with your code. You should check for error returned by setLanguage. You cannot call speakOut until onInit has been called. One way you can insure this is to disable the talk button in the xml layout file and enable it in onInit.

im trying to move the info of a user from one activity to the other, but everytime i run the app it crashes at the "startActivity(i)" Line (i checked everything else, it only crashes at that line).
that's the MainActivity Code

import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

import android.widget.Toast;
import com.example.hw1511.Model.User;
import org.w3c.dom.Text;
import java.io.Serializable;
import java.util.LinkedList;
import java.util.List;
public class MainActivity extends AppCompatActivity implements Serializable {
private EditText Name;
private EditText Age;
private EditText Birth;
private Button AddUser;
private Button Send;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Name = findViewById(R.id.Name);
Age = findViewById(R.id.Age);
Birth = findViewById(R.id.Birth);
AddUser = findViewById(R.id.AddUser);
Send = findViewById(R.id.Send);
Intent i = new Intent(MainActivity.this, SecondActivity.class);
List<User> list1 = new LinkedList<>();
AddUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (Name.getText().toString().trim().length() > 0 && Age.getText().toString().trim().length() > 0 && Birth.getText().toString().trim().length() > 0) {
User u = new User(Name.getText().toString(), Integer.parseInt(Age.getText().toString()), Birth.getText().toString());
list1.add(u);
Name.setText("");
Age.setText("");
Birth.setText("");
}
else {
Toast.makeText(MainActivity.this, "Fill All", Toast.LENGTH_SHORT).show();
}
}
});
Send.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
i.putExtra("Users", (Serializable) list1);
startActivity(i);
}
});
}
}
and that's the SecondActivty Code (it's preety much empty)

please if anyone help me understand what is making my app crash everytime i press the send button! it would really help me a lot.
Your User objects need to implement Serializable as well.
Also, since LinkedLists are Serializable you can use putSerializable(String key, Serializable value) instead of putExtra
How can I get String from my database and combine it with Image from my drawable folder. Help Please.
this is my main activity.

First I will describe the process/problem briefly in words. Afterwards, I'll attach all of the code.
I start the android application in debug mode.
Main activity gets called.
It calls Activity2 via "intent".
Then (in onCreate) I start an Async activity in order to get information from a webserver. I do that with this command "new Kontakt(info1, info2, information).execute();"
I've put a break point at the onPostExecute method in "Kontakt" to see what happens. But!! It doesn't stop there. So then I figured, "okey, the doInBackground method didn't get called for some reason"
When I continue to run the code, as a surprise, onPostExecute gets called (somewhere at the end of onClick) and stops at the break point just the way I want it but than it's too late, because I'd like to have the output already in the onCreate method where I called "new Kontakt(info1, info2, information).execute();".
So why does it call onPostExecute too late and what can I do to make the process call it properly already in onCreate at the line "new Kontakt(info1, info2, information).execute();" in Activity2?
The code is below

In Activity2, when onCreate() calls new Kontakt(info1, info2, information).execute();:
an asynchronous task (Kontakt) is started in the background
the execution of onCreate() continues
so it's normal that you don't have the response immediately.
